MabVax Therapeutics Holdings, Inc.
Company Background
We are a Delaware corporation, originally incorporated in 1988 under the name Terrapin Diagnostics, Inc. in the state of Delaware, and subsequently renamed “Telik, Inc.” in 1998, and thereafter renamed MabVax Therapeutics Holdings, Inc. in September 2014. Our principal corporate office is located at 11588 Sorrento Valley Road, Suite 20, San Diego, CA 92121 telephone: (858) 259-9405. Our internet address is www.mabvax.com. On July 8, 2014, we consummated a merger with MabVax Therapeutics, pursuant to which our subsidiary Tacoma Acquisition Corp. merged with and into MabVax Therapeutics, with MabVax Therapeutics surviving as our wholly owned subsidiary. This transaction is referred to as the “Merger.”
On September 8, 2014, we filed an amended and restated certificate of incorporation to increase the authorized number of shares of our common stock to 150,000,000 shares, increase the number of shares of our authorized preferred stock to 15,000,000 shares, and change our name to “MabVax Therapeutics Holdings, Inc.”
Business Overview
 
We are a clinical-stage biopharmaceuticalbiotechnology company focused on discovering and developing innovative monoclonalthe development of antibody-based therapeutics and vaccines forproducts to address unmet medical needs in the diagnosis and treatment of cancer.  MabVax has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been vaccinated against targeted cancers with our proprietary vaccines.  MabVax's lead development program is centered around our HuMab-5B1 antibody, which is fully human and discovered from the immune response of cancer patients vaccinated with an antigen-specific vaccine during a Phase I trial at Memorial Sloan Kettering Cancer Center, or MSK.   The antigen the antibody targets is expressed on more than 90% of pancreatic cancers, and expressed in significant percentages on small cell lung cancer, stomach, colon and other cancers, making the antibody potentially broadly applicable to many types of cancers.  We have other antibody candidates that are also in preclinical development.
Monoclonal antibodies are produced from a single DNA sequence encoded into multiple cells that all produce the same single antibody. We generate our pipeline of antibody-based product candidates from patients who have been vaccinated with proprietyproprietary vaccines licensed from Memorial Sloan Kettering Cancer Center (“MSK”).MSK. Our approach involves surveying the protective immune response from many patients to identify the ideala monoclonal antibody candidate against a specific target on the surface of a cancer cell. We believe this approach provides us with a novel next-generation human antibody technology platform. We believe our approach to antibody discovery identifies theallows us to identify antibody candidates with superior performance characteristics while minimizing many of the toxicity and off target binding drawbacks (phenomenon occurring when antibodies bind to non-cancer cells) of other discovery technologies. Our lead antibody candidates have been recovered from patients who have been reported to have had substantially better treatment outcomes than other patients in the clinical trials conducted by us and our partners.technologies.
 
Our therapeutic vaccines were developed at MSK and are exclusively licensed to us pursuant to agreements entered into in 2008. These vaccines are administered in the adjuvant setting (the period following completion of conventional treatment and consisting primarily of watchful waiting) and have been shown to elicit a protective antibody response in clinical studies. The antibodies are intended to seek out circulating tumor cells and micrometastases (small clusters of cancer cells) to kill them before they can cause cancer recurrence. Our lead cancer vaccines targeting recurrent sarcoma (soft tissue cancer) and ovarian cancer are currently in proof of concept Phase II multi-center clinical trials. Both trials have received substantial federal grant monies to support their development.

Our Growth and Core Business Strategy
 
Our primary business strategy is to develop our early antibody product candidates through proof of concept clinical trials, which may represent either phase I or phase II clinical trials depending on the program and extent of progress. We intend to then partner those product candidates having the highest clinical and commercial potential from our discovery library of antibody candidates obtained from blood samples from patients who have been vaccinated with proprietary vaccines licensed from MSK.  candidates.
Our Clinical Development Programs and Plans for 2017
 
Recent DevelopmentsMVT-5873 – for the Treatment of Pancreatic Cancer
 
PhaseIn our progress report released in November 2016, we stated that the safety of our HuMab-5B1 antibody designated as MVT-5873 had been established at three incremental dose levels in our phase I Clinical Trialclinical trial. The purpose of HuMab-5B1 – In December 2015, we received notice from the U.S. Food and Drug Administration (FDA) authorizing the initiation of a Phasethis phase I clinical trial, with HuMab-5B1 as a therapeutic treatment for pancreatic cancer.  We filed an Investigational New Drug (IND) application for our lead fully human antibody product on November 30, 2015.  Patient enrollmentinitiated in the Phase I clinical trialFebruary 2016, is expected to begin at multiple investigational sites in the first quarter of 2016.  The Phase I trial will evaluate theestablish safety and tolerability, and pharmacokineticsto determine the recommended phase II dose for patients with locally advanced and metastatic pancreatic cancer or other malignancies expressing the same cancer antigen known as CA19-9. Patients entering this part of HuMab 5B1 as a single agent orthe trial were stage three and stage four cancer patients who had failed all previous treatments, and had progressive disease.
Study protocol allows patients to remain on therapy beyond the initial 28-day treatment and safety assessment cycle based on acceptable dose tolerability and investigator assessment of continued benefit from the treatment. Every second treatment cycle the investigator assesses disease status using RECIST 1.1 measurement criteria to evaluate tumor response rate and duration of response.
After establishing the current dosage safety level for MVT-5873 in combinationPart 1 of the trial, we were able to initiate part 2 of our phase I study. Part 2 combines MVT-5873 with a standard of care chemotherapy regimen in subjectsnewly diagnosed treatment naïve patients. The dosage levels established in our MVT-5873 monotherapy trial also have cleared all subsequent dose levels utilized in our Phase I clinical study of MVT-2163 as an immuno-PET imaging agent as well as the dose levels planned for our clinical study of our radioimmunotherapy product MVT-1075 that combines MVT-5873 with metastatic pancreatic cancer.  The first cohorta radioactive substance.
Recent progress – As of April 2017, we had enrolled 29 patients in Part 1 of our phase I trial at three clinical sites. Twenty-five patients are currently evaluable. We have seen an efficacy signal from early study results primarily in patients who enter the trial with CA19-9 levels below 2,500 U/ml. In this group of patients, will be enrolledwe observed that the first cycle of treatment with MVT-5873 reduces CA19-9 levels by 95% or more and close to normal levels. We also observed that approximately half of the patients with CA19-9 levels below 2,500 U/ml. convert from progressive disease to stable disease. Further, approximately 30% of this responder set maintained stable disease for four or more months. Patients continue to tolerate the study drug reasonably well with drug infusion reactions being the most common adverse event which is adequately addressed by slowing the infusion rate and use of routine premedication. Increases in liver function tests are seen early in a traditional dose escalation regimen to assess safety and determine the optimal dose of the antibody.  A second patient cohort will establish the safety and optimized dose of the antibody when administered with a standard of care chemotherapy.   Two additional patient cohorts will be administered the optimized dose of antibody as a single agent, or in combination with a standard of care chemotherapy regimen, for the treatmentminority of patients with pancreatic cancer.and appear reversible.
 
Phase I Clinical TrialPlan for remainder of 201789Zr-HuMab-5B1In January 2016, we filed an IND application withWe plan to conduct a small phase Ib study in the FDA for 89Zr-HuMab-5B1, utilizing our fully human antibody productsecond half of 2017 to evaluate the use of MVT-5873 as a new generation PET scan cancer imaging agent.  Subject to FDA authorization to proceed, we plan to initiate the Phase I clinical trial in patients with pancreatic cancer in early 2016.  The 89Zr-HuMab-5B1 imaging agent has demonstrated high-resolution images of tumors in xenograft animal models, potentially making it an important new tool to aid in the diagnosis, monitoring and assessment ofmaintenance therapy for pancreatic cancer patients whose chemotherapy treatments no longer provide improvement and are experiencing increasing levels of toxicity. We believe we can demonstrate proof-of-concept for this approach with a small cohort of approximately 10 patients. Results from this study are anticipated around year end 2017.
MVT-2163 –as an attractive companion diagnosticImaging Agent for the HuMab-5B1 therapeutic product. This second planned Phase I trial will evaluate thePancreatic Cancer
In our progress report released in November 2016, we stated that we had established interim safety, and acceptable pharmacokinetics and biodistribution of our immuno-PET imaging agent that we designate as MVT-2163 in our phase I clinical trial. MVT-2163 is comprised of MVT-5873 conjugated to a radio label. We have completed the initial two cohorts of patients as specified in our protocol. In the first cohort, we administered MVT-2163 alone and in the second cohort we administered MVT-2163 following a blocking dose of MVT-5873. We reported that the initial PET images demonstrated target specificity by correlation with lesions identified by conventional computerized tomography (CT) scans. The biodistribution data obtained in the first two cohorts demonstrated improvement in PET images by pre-administration of MVT-5873, as has been observed with other antibody based PET agents. We initiated the MVT-2163 phase I trial in June 2016 to evaluate a next generation diagnostic PET imaging agent in patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies. MVT-2163 (89Zr-HuMab-5B1) combines the well-established PET imaging radiolabel Zirconium [Zr-HuMab-5B1 in cancer patients.  The89Zr] with the targeting specificity of MVT-5873. We designed the trial will also purport to determineestablish safety, pharmacokinetics, biodistribution, optimal time to obtain the ideal dosePET image, and conditions for an optimalthe amount of MVT-5873 to be used prior to administration of MVT-2163 to obtain optimized PET scan image usingimages. We continue to actively recruit patients and expect to establish the new imaging agent.

Oxford Loan – On January 15, 2016, we entered into a Loan and Security Agreement with Oxford Finance LLC providing for senior secured term loans to usoptimal co-administration dose of MVT-5873 early in the aggregate principal amount of up to $10,000,000.  On January 15, 2016, we received an initial loan of $5,000,000 under the Loan and Security Agreement.2017.
Underwritten Offering – On September 30, 2015, we entered into an underwriting agreement with Laidlaw & Company (UK) Ltd. relating to the issuance and sale in a public offering of 2,500,000 shares of the Company’s common stock and 1,250,000 three-year warrants to purchase 1,250,000 shares of the Company’s common stock at an initial exercise price of $1.32 per share. The shares of common stock were sold at a public offering price of $1.10 per share and the warrants were sold at a price of $0.01 per warrant. The offering closed on October 5, 2015 with total gross proceeds to us of $2,750,000.

Recent progress – As of April Private Placement – On March 31, 2015of 2017 we had completed enrollments in the phase 1a portion of our study in all three planned cohorts. We have expanded cohort 3 to evaluate not only an increased blocking dose but the impact of expanding the time interval between the administration of a blocking dose and April 10, 2015, we entered into separate subscription agreements with accredited investors relatingthe MVT-2163 PET agent. We have determined that a 47 mg. blocking dose and a time interval of 2 to 4 hours significantly improves the issuance and sale of $11,714,498 of units at a purchase price of $0.75 per unit, with each unit consisting of one share of  common stock (or, at the election of any investor who, as a result of receiving common stock would hold in excess of 4.99%quality of the Company’s issuedPET scan image.

Images seen from use of MVT-2163 appear to purchase one halfbe identifying smaller metastatic sites that are below the limit of one share of common stock at an initial exercise price of $1.50 per share (such sale and issuance, the “April Private Placement,” or the “Private Placement”). We conducted an initial closing of the April Private Placement on March 31, 2015 in which we sold an aggregate of $4,995,750 of units. Following the initial closing we entered into separate reconfirmation agreementsdetection with the investors in order to extend the initial closing date, increase the offering amount, and adopt a lockup agreement which was entered into by all investors who elected to continue their investment. A second closing was held on April 10, 2015 in which we entered into separate subscription agreements for the sale of an additional $6,718,751 of units.CT scans.
On April 14, 2015, as a condition to participation by OPKO Health, Inc. (“OPKO”) and Frost Gamma Investments Trust (“FGIT”) in the April Private Placement, we entered into an Escrow Deposit Agreement with Signature Bank N.A. and OPKO, as amended on June 22, 2015, pursuant to which $3.5 million from the April Private Placement was deposited into and held at Signature Bank.  The escrowed funds were released us on June 30, 2015 as part of a letter agreement giving OPKO the right, but not the obligation, until June 30, 2016, to nominate and have appointed up to two additional members of the our Board of Directors, or to approve the person(s) nominated by the Company.  The nominees will be subject to satisfaction of standard corporate governance practices and any applicable national securities exchange requirements.

Preferred and Warrant Holders Common Stock Exchange Agreements

On March 25, 2015, we entered into separate exchange agreements (collectively, the “Exchange Agreements”) with certain holders of our Series A-1 Preferred Stock and A-1 Warrants and holders of our Series B Preferred Stock and Series B Warrants, all previously issued by us. Pursuant to the Exchange Agreements, the holders exchanged their respective preferred shares and warrants and relinquished any and all other rights they may have pursuant to such securities, their respective governing agreements and certificates of designation, including any related registration rights, in exchange for an aggregate of 2,537,502 shares of our common stock and an aggregate of 238,156 shares of our newly designated Series D Convertible Preferred Stock  (collectively the “Exchange Securities”).

Plan for remainder of 2017 – In consultation with our clinical investigators, we plan to expand our phase 1 program for the remainder of 2017 to include additional patients who will consent to have the smaller potential metastatic sites being seen with MVT-2163 images biopsied to provide evidence that MVT-2163 is identifying previously unseen disease. Better understanding of the extent and spread of the cancer will significantly improve the clinical decision regarding eligibility for curative surgery. We expect to have results of biopsies later in 2017.
MVT-1075 –as a Radioimmunotherapy for Pancreatic Cancer
We are developing HuMab-5B1 into a third potential product for use as a radioimmunotherapy that we have designated as MVT-1075. MVT-1075 represents a unique product opportunity for MabVax by conjugating MVT-5873 with a low-energy radiation emitter, 177Lu, which has a relatively short tissue penetration range to minimize potential side effects of the radiation. MVT-5873 provides the opportunity for tumor-specific targeting of a more potent analog of MVT-5873. We submitted our IND in late December 2016, and the IND was authorized to proceed on January 27, 2017. We plan to initiate the phase I trial of MVT-1075 in the first half of 2017.

We are a Delaware corporation, originally incorporated in 1988 under the name Terrapin Diagnostics, Inc. in the state of Delaware, and subsequently renamed “Telik, Inc.” in 1998, and thereafter renamed MabVax Therapeutics Holdings, Inc. in September 2014. Our principal corporate office is located at 11535 Sorrento Valley Road, Suite 400, San Diego, CA 92121 and our telephone number is (858) 259-9405. On July 8, 2014, we consummated a merger with MabVax Therapeutics, pursuant to which our subsidiary Tacoma Acquisition Corp. merged with and into MabVax Therapeutics, with MabVax Therapeutics surviving as our wholly owned subsidiary. This transaction is referred to as the “Merger.” Our internet address iswww.mabvax.com. Information on our website is not incorporated into this prospectus.
Listing Reverse Split
On August 2, 2016, the Board approved a 1-for-7.4 reverse stock split, or the Listing Reverse Split. The Listing Reverse Split was intended to allow us to meet the minimum share price requirement of The NASDAQ Capital Market, or NASDAQ. On August 11, 2016, we received approval from The NASDAQ Capital Market for the listing of our common stock under the symbol “MBVX”, subject to implementation of the Listing Reverse Split and closing of our August 2016 public offering (the “August 2016 Public Offering,” and the investors in the August 2016 Public Offering, the “August 2016 Investors”). On August 16, 2016, we implemented the Listing Reverse Split, closed on the August 2016 Public Offering and began trading on The NASDAQ Capital Market at the open of business on August 17, 2016. Unless otherwise stated herein, all per share amounts herein give effect to the Listing Reverse Split.

RISK FACTORS
 
Any investment in our common stocksecurities involves a high degree of risk. Investors should carefully consider the risks described below and all of the information contained in this prospectus before deciding whether to purchase our common stock.securities. Our business, financial condition and results of operations could be materially adversely affected by these risks if any of them actually occur. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face as described below and elsewhere in this prospectus.
 
General Risks

We will be required to raise additional funds to finance our operations and remain a going concern; we may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us.
 
Our operations to date have consumed substantial amounts of cash. Negative cash flows from our operations are expected to continue over at least the next several years. Our cash utilization amount is highly dependent on the progress of our product development programs, particularly, the results of our preclinical and clinical studies and those of our partners, the cost, timing and outcomes of regulatory approval for our product candidates, and the rate of recruitment of patients in our human clinical trials. In addition, the further development of our ongoing clinical trials will depend on upcoming analysis and results of those studies and our financial resources at that time.
 
We will require future additional capital infusions including public or private financing, strategic partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or products, in order to continue the development of our product candidates. However, there can be no assurances that we will complete any financings, strategic alliances or collaborative development agreements, and the terms of such arrangements may not be advantageous to us. Any additional equity financing will be dilutive to our current stockholders and debt financing, if available, may involve restrictive covenants. If we raise funds through collaborative or licensing arrangements, we may be required to relinquish, on terms that are not favorable to us, rights to some of our technologies or product candidates that we would otherwise seek to develop or commercialize. Our failure to raise capital when needed could materially harm our business, financial condition and results of operations.
 
Additionally, we are prohibited from issuinggranted certain rights to approve future (i) issuances of our securities, (ii) equity or debt financings and (iii) sales of any development product assets currently held by us, subject to certain exceptions, for as long as the lead investor in our August 2016 Public Offering holds 50% or more of the shares of common stock (or Series F Preferred Stock) purchased by the lead investor in the August 2016 Public Offering or until a financing with net proceeds to us of at least $7.5 million in which we are able to sell our securities at a minimum per share price of $7.40 or greater (the “Consent”). In connection with this offering, we have agreed with the lead investor of the August 2016 Public Offering to issue up to 2,900,000 shares of common stock to the August 2016 Investors, as incentive shares to those investors to make a minimum required investment in this public offering of at least 50% of their investment in the $9.4 million August 2016 Public Offering, or the Minimum Required Investment, and who still hold 100% of the shares of common stock. Such August 2016 Investors shall be entitled to receive their pro rata share of 2,900,000 shares, after the lead investor in this offering receives the first 10%. In the event the August 2016 Investors purchased Series F Preferred Stock and make the Minimum Required Investment and who still hold 100% of the shares of Series F Preferred Stock at the closing of this offering, then the conversion rate for the Series F Preferred Stock would change only for those investors making the Minimum Required Investment, resulting in an increase of up to 1,163,291 in the number of shares of common stock that the Series F Preferred Stock may be converted into, assuming all holders of Series F Preferred Stock make the Minimum Required Investment, or from 665,281 to 1,828,572 common share equivalents. In the event of a liquidation, dissolution or winding up of the Company, each share of Series F preferred stock will be entitled to a per share preferential payment equal to the par value of $0.01 per share. There is no adjustment required by the Series F Certificate of Designations as a result of pricing in financings, and is being offered by the Company as an incentive for participation in this financing by the holders of Series F Preferred Stock. The August 2016 Investors who still hold 100% of their shares from the August 2016 Public Offering and make the Minimum Required Investment in this offering in order to receive a portion of the 2,900,000 shares, will have their outstanding warrants, exercisable at a price of $5.55 and $6.29, respectively, from the August 2016 Public Offering, cancelled.
Further, as an inducement for investors in our April 2015 financing to participate in this financing, and provided the April 2015 investors invest at least 25% of their original investment in the April 2015 financing and still hold 100% of their common stock or Series E preferred stock from the April 2015 financing, then up to 805,361 warrants to purchase common stock at $11.10 per share that were issued in that financing will be reduced to $2.00 per share and the cashless exercise provision shall be removed. To the extent there is less than 100% participation, the number of warrants offered for repricing would be reduced pro rata.
Further, if this offering is consummated for at least $10 million in capital from investors who are not security holders from the August 2016 Public Offering, the lead investor’s Consent right will terminate. Should the Consent be required in connection with future offerings, we may be required again to provide additional consideration, including, but not limited to, consideration in the form of cash and/or additional shares of our capital stock and/or securities convertible into or exercisable for shares of our capital stock, in order to obtain the Consent.  If we are unable to obtain the Consent when necessary for future offerings, we may be unable to raise additional funds. An inability to raise additional funds could have a material adverse effect on our financial condition, results of operations, ability to conduct our business and on the price of our common stock, enter intostock. We have also granted the lead investor in this offering certain rights to approve future (i) issuances of our securities, (ii) equity or debt financings and (iii) sales of any equity line of credit or issue any floating or variable priced equity linked instrument withoutdevelopment product assets currently held by us, subject to certain exceptions, if such securities are sold at price below $2.50 per share and for as long as the consent of a certain recipient of Exchange Securities untillead investor in the earlier to occur of: (a) April 1, 2017; (b) the date on which the Company has raised $10 million in equity financing; (c) the date on which the Company has closed oneoffering holds 50% or more licensing agreements with corporate partners pursuant to whichof the Company is entitled to receive in total a minimum of $10,000,000 in initial licensing or equity investments under such agreements; and (d) the date on which shares of Series G Preferred Stock purchased by the Company's common stock are listed on a national securities exchange.  These arrangements may make it difficult for us to raise or borrow additional funds.lead investor in this offering.
 
Our ongoing capital requirements will depend on numerous factors, including: the progress and results of preclinical testing and clinical trials of our product candidates under development; the costs of complying with the FDA and other domestic and foreign regulatory agency requirements, the progress of our research and development programs and those of our partners; the time and costs expended and required to obtain any necessary or desired regulatory approvals; the resources that we devote to manufacturing expenditures; our ability to enter into licensing arrangements, including any unanticipated licensing arrangements that may be necessary to enable us to continue our development and clinical trial programs; the costs and expenses of filing, prosecuting and, if necessary, enforcing our patent claims, or defending against possible claims of infringement by third-party patent or other technology rights; the cost of commercialization activities and arrangements, if any, that we undertake; and, if and when approved, the demand for our products, which demand depends in turn on circumstances and uncertainties that cannot be fully known, understood or quantified unless and until the time of approval, including the range of indications for which any product is granted approval.
The terms of our secured debt facility require us to meet certain operating and financial covenants and place restrictions on our operating and financial flexibility. If we raise additional capital through debt financing, the terms of any new debt could further restrict our ability to operate our business.

Effective in January 2016, we entered into a $10 million loan and security agreement with Oxford Finance LLC, or Oxford Finance, that is secured by a lien covering substantially all of our assets, excluding intellectual property. As of December 31, 2016, we had an outstanding principal balance of $5 million.The option to draw the second $5 million expired on September 30, 2016. The loan and security agreement contains customary affirmative and negative covenants and events of default. The affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports and maintain insurance coverage. The negative covenants include, among others, restrictions on transferring collateral, changing our business, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments and creating other liens on our assets, in each case subject to customary exceptions. As of May 11, 2017, we were in compliance with all the covenants. If we default under the loan agreement, the lenders may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately cease operations. Further, if we are liquidated, the lender’s right to repayment would be senior to the rights of the holders of our common stock and preferred stock to receive any proceeds from the liquidation. The lenders could declare a default upon the occurrence of any event that they interpret as a material adverse change as defined under the loan agreement, thereby requiring us to repay the loan immediately or to attempt to reverse the declaration of default through negotiation or litigation. Any declaration by the lenders of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.
 
We have a history of losses, and we anticipate that we will continue to incur losses in the future; our auditors have included in their audit report an explanatory paragraph as to substantial doubt as to our ability to continue as a going concern.
 
We have experienced net losses every year since our inception and, as of December 31, 2014 and September 30, 2015,2016, had an accumulated deficit of $24,550,308 and $56,619,570, respectively.$78,262,261. Our auditors have included in their audit report a “going concern” explanatory paragraph as to substantial doubt as to our ability to continue as a going concern that assumes the realization of our assets and the satisfaction of our liabilities and commitments in the normal course of business. We anticipate continuing to incur substantial additional losses over at least the next several years due to, among other factors, expenses related to the following: the GMP manufacture of our 5B1 antibody to create clinical trial supplies, conducting Phase I clinical trials with the 5B1HuMab-5B1 antibody, preclinical testing of follow-on antibody candidates, investor and public relations, SEC compliance efforts, anticipated research and development activities and the general and administrative expenses associated with each of these activities. We have not yet commercialized any product candidates. Our ability to attain profitability will depend upon our ability to develop and commercialize products that are effective and commercially viable, to obtain regulatory approval for the manufacture and sale of our products and to license or otherwise market our products successfully. We may never achieve profitability, and even if we do, we may not be able to sustain being profitable. If we are unable to obtain additional capital we may be forced to license, sell or terminate our activities with respect to promising technologies which may require us to agree to disadvantageous terms that will prevent us from realizing the potential value from the results of our efforts and expenditures.
 
If we are unable to obtain required regulatory approvals, we will be unable to market and sell our product candidates.
 
Our product candidates are subject to extensive governmental regulations relating to development, clinical trials, manufacturing, oversight of clinical investigators, recordkeeping and commercialization. Rigorous preclinical testing and clinical trials and an extensive regulatory review and approval process are required to be successfully completed in the United States and in each foreign jurisdiction in which we offer our products before a new drug or other product can be sold in such jurisdictions. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain, and subject to unanticipated delays. The time required to obtain approval by the FDA, or the regulatory authority in such other jurisdictions is unpredictable and often exceeds five years following the commencement of clinical trials, depending upon the complexity of the product candidate and the requirements of the applicable regulatory agency.
 
In connection with the clinical development of our product candidates, we face risks that:
the product candidate may not prove to be safe and efficacious;
 
patients may die or suffer serious adverse effects for reasons that may or may not be related to the product candidate being tested;
 
we may fail to maintain adequate records of observations and data from our clinical trials, to establish and maintain sufficient procedures to oversee, collect data from, and manage clinical trials, or to monitor clinical trial sites and investigators to the satisfaction of the FDA or other regulatory agencies;
 
the results of later-phase clinical trials may not confirm the results of earlier clinical trials; and
 
the results from clinical trials may not meet the level of statistical significance or clinical benefit-to-risk ratio required by the FDA or other regulatory agencies for marketing approval.
Only a small percentage of product candidates for which clinical trials are initiated receive approval for commercialization. Furthermore, even if we do receive regulatory approval to market a product candidate, any such approval may be subject to limitations such as those on the indicated uses for which we may market a particular product candidate.
 
Our management and our independent registered public accounting firm identified certain material weaknesses in our internal control over financial reporting upon completion of our audit in May of 2014 that were not fully remediated as of December 31, 2014. While we have implemented certain internal controls to address material weaknesses, if we are unable to maintain effective internal control, we may not be able to produce timely and accurate financial statements, and our independent registered public accounting firm could conclude that our internal control over financial reporting is not effective, which could adversely impact investor confidence and our stock price.
 
In connection with the audit
-8-
Table of our financial statements as of and for the year ended December 31, 2014, our management and our independent registered public accounting firm identified material weaknesses in our internal control over financial reporting relating to the reporting of non-routine complex transactions and the lack of segregation of duties. These material weaknesses were primarily the result of a limited number of employees in our accounting department. In June 2014, we added an assistant controller, a person dedicated solely to processing accounts payable, and another person dedicated to reviewing and reporting on clinical trials progress and expenses. In April 2015, the assistant controller was promoted to controller and we hired a Senior Director of Finance to take over some of the responsibilities of the controller and Chief Financial Officer, so that the Chief Financial Officer is able to perform review functions on significant transactions on a going forward basis. These persons have continued to work in these capacities following the Merger. On March 25, 2015 we filed with the SEC an amended quarterly report for the quarter ended September 30, 2014, to correct certain errors in our financial statements for that period, namely an error in accounting for employee severance expense relative to the July 2014 Merger. On October 30, 2015, we filed with the SEC our quarterly report for the quarter ended September 30, 2015 in which we disclosed that management had concluded that we continued to have material weaknesses in our internal control related to segregation of duties and recording of complex accounting transactions for the period ended September 30, 2015. Additional errors may occur if we are not able to eliminate the material weaknesses in our internal control over financial reporting. Our management is responsible for maintaining, implementing and testing our internal controls over financial reporting. These efforts are intended to maintain an effective control environment but may not be sufficient to remediate any material weaknesses identified by our independent registered accounting firm and may not prevent significant deficiencies from occurring.Contents

Our product candidates have not completed clinical trials, and may never demonstrate sufficient safety and efficacy in order to do so.
 
Our product candidates are in the clinical and pre-clinical stages of development. In order to achieve profitable operations, we alone, or in collaboration with others, must successfully develop, manufacture, introduce and market our products. The time frame necessary to achieve market success for any individual product is long and uncertain. The products we are currently developing will require significant additional research, development and preclinical and clinical testing prior to application for commercial use or sale. A number of companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in clinical trials, even after showing promising results in early or later-stage studies or clinical trials. Although we have obtained some favorable results to-date in preclinical studies and clinical trials of certain of our potential products, such results may not be indicative of results that will ultimately be obtained in or throughout such clinical trials, and clinical trials may not show any of our products to be safe or capable of producing a desired result. Additionally, we may encounter problems in our clinical trials that may cause us to delay, suspend or terminate those clinical trials.
 
Further, our research or product development efforts may not be successfully completed, any compounds we currently have under development may not be successfully developed into drugs, may not receive regulatory approval on a timely basis, if at all, and competitors may develop and bring to market products or technologies that render our potential products obsolete. If any of these events occur, our business would be materially and adversely affected.
 
If clinical trials or regulatory approval processes for our product candidates are prolonged, delayed or suspended, we may be unable to commercialize our product candidates on a timely basis, which would require us to incur additional costs and delay our receipt of any revenue from potential product sales.
 
We cannot predict whether we will encounter problems with any of our completed, ongoing or planned clinical trials that will cause us or any regulatory authority to delay or suspend those clinical trials or delay the analysis of data derived from them. A number of events, including any of the following, could delay the completion of our ongoing and planned clinical trials and negatively impact our ability to obtain regulatory approval for, and to market and sell, a particular product candidate:
conditions imposed on us by the FDA or another foreign regulatory authority regarding the scope or design of our clinical trials;
delays in obtaining, or our inability to obtain, required approvals from institutional review boards or other reviewing entities at clinical sites selected for participation in our clinical trials;
 
insufficient supply of our product candidates or other materials necessary to conduct and complete our clinical trials;
 
slow enrollment and retention rate of subjects in our clinical trials;
 
serious and unexpected drug-related side effects related to the product candidate being tested; and
 
delays in meeting manufacturing and testing standards required for production of clinical trial supplies.
 
Commercialization of our product candidates may be delayed by the imposition of additional conditions on our clinical trials by the FDA or any other applicable foreign regulatory authority or the requirement of additional supportive studies by the FDA or such foreign regulatory authority. In addition, clinical trials require sufficient patient enrollment, which is a function of many factors, including the size of the patient population, the nature of the trial protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease, the conduct of other clinical trials that compete for the same patients as our clinical trials, and the eligibility criteria for our clinical trials. Our failure to enroll patients in our clinical trials could delay the completion of the clinical trial beyond its expectations. In addition, the FDA could require us to conduct clinical trials with a larger number of subjects than we may have projected for any of our product candidates. We may not be able to enroll a sufficient number of patients in a timely or cost-effective manner. Furthermore, enrolled patients may drop out of our clinical trials, which could impair the validity or statistical significance of the clinical trials.
 
We do not know whether our clinical trials will begin as planned, will need to be restructured, or will be completed on schedule, if at all. Delays in our clinical trials will result in increased development costs for our product candidates, and our financial resources may be insufficient to fund any incremental costs. In addition, if our clinical trials are delayed, our competitors may be able to bring products to market before we do and the commercial viability of our product candidates could be limited. In cases where an outside party, such as the National Cancer Institute (“NCI”)NCI conducts a clinical trial on our behalf, we may not have direct involvement in discussions with the FDA regarding the factors discussed above.

 
We are substantially dependent on the success of our product candidates, MVT-5873, MVT-2163 and MVT-1075, and we cannot provide any assurance that any of our product candidates will be commercialized.
To date, our main focus and the investment of a significant portion of our efforts and financial resources has been in the development of our product candidates, MVT-5873, MVT-2163, and MVT-1075, which are in clinical development. Our future success depends heavily on our ability to successfully manufacture, develop, obtain regulatory approval, and commercialize these product candidates, which may never occur.  Before commercializing either product candidate, we will require additional clinical trials and regulatory approvals for which there can be no guarantee that we will be successful. We currently generate no revenues from our product candidates, and we may never be able to develop or commercialize a marketable drug.
Our product candidates will remain subject to ongoing regulatory review even if they receive marketing approval, and if we fail to comply with continuing regulations, we could lose these approvals and the sale of any of our approved commercial products could be suspended.
 
Even if we receive regulatory approval to market a particular product candidate, the manufacturing, labeling, packaging, adverse event reporting, storage, advertising, promotion, and record keeping related to the product will remain subject to extensive regulatory requirements. If we fail to comply with the regulatory requirements of the FDA and other applicable domestic and foreign regulatory authorities or discover any previously unknown problems with any approved product, manufacturer, or manufacturing process, we could be subject to administrative or judicially imposed sanctions, including:
restrictions on the products, manufacturers, or manufacturing processes;
warning letters;
 
warning letters;
civil or criminal penalties;
fines;
 
injunctions;
fines;
injunctions;
product seizures or detentions;
pressure to initiate voluntary product recalls;
suspension or withdrawal of regulatory approvals; and
refusal to approve pending applications for marketing approval of new products or supplements to approved applications.
 
Our industry is highly competitive, and our product candidates may become obsolete.
 
We are engaged in a rapidly evolving field. Competition from other pharmaceutical companies, biotechnology companies and research and academic institutions is intense and likely to increase. Many of those companies and institutions have substantially greater financial, technical and human resources than we do. Those companies and institutions also have substantially greater experience in developing products, conducting clinical trials, obtaining regulatory approval and in manufacturing and marketing pharmaceutical products. Our competitors may succeed in obtaining regulatory approval for their products more rapidly than we do. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. We are aware of potential competitors developing products similar to our sarcoma vaccine, ovarian cancer vaccine and pancreatic cancer antibodies product candidates. Our competitors may succeed in developing products that are more effective and/or cost competitive than those we are developing, or that would render our product candidates less competitive or even obsolete. In addition, one or more of our competitors may achieve product commercialization or patent protection earlier than we do, which could materially adversely affect our business.

 
If physicians and patients do not accept our future products or if the market for indications for which any product candidate is approved is smaller than expected, we may be unable to generate significant revenue, if any.
 
Even if any of our product candidates obtain regulatory approval, they may not gain market acceptance among physicians, patients, and third-party payers. Physicians may decide not to recommend our treatments for a variety of reasons including:
timing of market introduction of competitive products;
demonstration of clinical safety and efficacy compared to other products;
 
demonstration of clinical safety and efficacy compared to other products;cost-effectiveness;
 
cost-effectiveness;
limited or no coverage by third-party payers;
convenience and ease of administration;
prevalence and severity of adverse side effects;
restrictions in the label of the drug;
other potential advantages of alternative treatment methods; and
ineffective marketing and distribution support of its products.
 
If any of our product candidates are approved, but fail to achieve market acceptance or such market is smaller than anticipated, we may not be able to generate significant revenue and our business would suffer.
 
As we evolve from being a company that is primarily involved in clinical development to a company that is also involved in commercialization, we may encounter difficulties in expanding our operations successfully.
 
As we advance our product candidates through clinical trials, we will need to expand our development, regulatory, manufacturing, marketing and sales capabilities and may need to further contract with third parties to provide these capabilities. As our operations expand, we likely will need to manage additional relationships with such third parties, as well as additional collaborators, distributors, marketers and suppliers.
 
Maintaining third party relationships for these purposes will impose significant added responsibilities on members of our management and other personnel. We must be able to: manage our development efforts effectively; recruit and train sales and marketing personnel; manage our participation in the clinical trials in which our product candidates are involved effectively; and improve our managerial, development, operational and finance systems, all of which may impose a strain on our administrative and operational infrastructure.
 
If we enter into arrangements with third parties to perform sales, marketing or distribution services, any product revenues that we receive, or the profitability of these product revenues to us, are likely to be lower than if we were to market and sell any products that we develop without the involvement of these third parties. In addition, we may not be successful in entering into arrangements with third parties to sell and market our products or in doing so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products effectively. If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our products.

The uncertainty associated with pharmaceutical reimbursement and related matters may adversely affect our business.
 
Market acceptance and sales of any one or more of our product candidates will depend on reimbursement policies and may be affected by future healthcare reform measures in the United States and in foreign jurisdictions. Government authorities and third-party payers, such as private health insurers and health maintenance organizations, decide which drugs they will cover and establish payment levels. We cannot be certain that reimbursement will be available for any of our product candidates. Also, we cannot be certain that reimbursement policies will not reduce the demand for, or the price paid for, our products. If reimbursement is not available or is available on a limited basis, we may not be able to successfully commercialize any product candidates that we develop.
 
In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, also called the Medicare Modernization Act, or MMA, changed the way Medicare covers and pays for pharmaceutical products. The legislation established Medicare Part D, which expanded Medicare coverage for outpatient prescription drug purchases by the elderly but provided authority for limiting the number of drugs that will be covered in any therapeutic class. The MMA also introduced a new reimbursement methodology based on average sales prices for physician-administered drugs.
 
The United States and several foreign jurisdictions are considering, or have already enacted, a number of legislative and regulatory proposals to change the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payers in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. We expect to experience pricing pressures in connection with the sale of any products that it develops due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals.
 
In March 2010,Moreover, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or collectively, ACA, became law in the U.S. The goal of ACA is intended to reduce the cost of health care and substantially change the way health care is financed by both government and private insurers. While we cannot predict what impact on federal reimbursement policies this legislation will have in general or on our business specifically, the ACA may result in downward pressure on pharmaceutical reimbursement, which could negatively affect market acceptance of, and the price we charge for, any products we develop that receive regulatory approval.
Our ability to generate product revenues will be diminished if our therapies sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.
Our ability to commercialize our therapies, alone or with collaborators, will depend in part on the extent to which reimbursement will be available from private health maintenance organizations and health insurers and other healthcare payers. Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers are challenging the prices charged for medical products and services. Cost control initiatives could decrease the price that we would receive for any products in the future, which would limit our revenue and profitability. Government and other healthcare payers increasingly attempt to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs and therapeutics. We also cannot predictmight need to conduct post-marketing studies in order to demonstrate the impactcost-effectiveness of ACA onany future products to such payers’ satisfaction. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Even if one of our business, as manyproduct candidates is approved by the FDA, insurance coverage may not be available, and reimbursement levels may be inadequate, to cover such therapies. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for one of the ACA reforms require the promulgationour products, once approved, market acceptance of detailed regulations implementing the statutory provisions, which have not yet been fully promulgated and implemented.such product could be reduced.
 
We only have a limited number of employees to manage and operate our business.
 
As of January 25, 2016,May 11, 2017, we hadhave a total of 1725 full-time employees and threetwo part-time employees. Our focus on limiting cash utilization requires us to manage and operate our business in a highly efficient manner. We cannot assure you that we will be able to retain adequate staffing levels to run our operations and/or to accomplish all of the objectives that we otherwise would seek to accomplish.
 
We depend heavily on our executive officers, directors, and principal consultants and the loss of their services would materially harm our business.
 
We believe that our success depends, and will likely continue to depend, upon our ability to retain the services of our current executive officers, directors, principal consultants and others. In addition, we have established relationships with universities, hospitals and research institutions, which have historically provided, and continue to provide, us with access to research laboratories, clinical trials, facilities and patients. The loss of the services of any of these individuals or institutions would have a material adverse effect on our business.

Our internal computer systems, or those of our third-party service providers, licensees, licensors, collaborators or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption in our business and operations.
Despite the implementation of security measures, our internal computer systems and those of our current and future service providers, licensees, licensors, collaborators and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we are not aware of any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed, on-going or future clinical trials could result in delays in our regulatory approval efforts and significant costs to recover or reproduce the data. Likewise, we rely on third parties to manufacture our drug candidates and conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liabilities and the further development and commercialization of our product candidates could be delayed.
 
Due in part to our limited financial resources, we may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable indications or therapeutic areas for our product candidates or those that are in-licensed, and/or we may be unable to pursue the clinical trials that we would like to pursue.
 
We have limited technical, managerial and financial resources to determine the indications on which we should focus the development efforts related to our product candidates. Due to our limited available financial resources, we may have to curtailcurtailed clinical development programs and activities that might otherwise leadhave led to more rapid progress of our product candidates through the regulatory and development processes.
 
We may make incorrect determinations with regard to the indications and clinical trials on which to focus the available resources that we do have. Furthermore, we cannot assure you that we will be able to retain adequate staffing levels to run our operations and/or to accomplish all of the objectives that we otherwise would seek to accomplish. Our decisions to allocate our research, management and financial resources toward particular indications or therapeutic areas for our product candidates may not lead to the development of viable commercial products and may divert resources from better opportunities. Similarly, our decisions to delay or terminate drug development programs may also cause us to miss valuable opportunities.
 
If the third parties on which we rely for the conduct of our clinical trials and results do not perform our clinical trial activities in accordance with good clinical practices and related regulatory requirements, we may be unable to obtain regulatory approval for or commercialize our product candidates.
 
We use independent clinical investigators and other third-party service providers to conduct and/or oversee the clinical trials of our product candidates and expect to continue to do so for the foreseeable future. We rely heavily on these parties for successful execution of our clinical trials. Nonetheless, we are responsible for confirming that each of our clinical trials is conducted in accordance with the FDA’s requirements and our general investigational plan and protocol.
 
The FDA requires us and our clinical investigators to comply with regulations and standards, commonly referred to as good clinical practices, for conducting and recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the trial participants are adequately protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule or may not conduct our clinical trials in accordance with regulatory requirements or the respective trial plans and protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our product candidates or result in enforcement action against us.
 
We have limited manufacturing capacity and have relied on, and expect to continue to rely on, third-party manufacturers to produce our product candidates.
 
We do not own or operate manufacturing facilities for the production of clinical or commercial quantities of our product candidates, and we lack the resources and the capabilities to do so. As a result, we currently rely, and expect to rely for the foreseeable future, on third-party manufacturers to supply our product candidates. Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured our product candidates or products ourselves, including:
reliance on third-parties for manufacturing process development, regulatory compliance and quality assurance;
limitations on supply availability resulting from capacity and scheduling constraints of third-parties;
the possible breach of manufacturing agreements by third-parties because of factors beyond our control; and
the possible termination or non-renewal of the manufacturing agreements by the third-party, at a time that is costly or inconvenient to us.
 
If we do not maintain our key manufacturing relationships, we may fail to find replacement manufacturers or develop our own manufacturing capabilities, which could delay or impair our ability to obtain regulatory approval for our products and substantially increases our costs or deplete profit margins, if any. If we do find replacement manufacturers, we may not be able to enter into agreements with them on terms and conditions favorable to us and there could be a substantial delay before new facilities could be qualified and registered with the FDA and other foreign regulatory authorities.
 
The FDA and other foreign regulatory authorities require manufacturers to register manufacturing facilities. The FDA and corresponding foreign regulators also inspect these facilities to confirm compliance with current cGMPs. Contract manufacturers may face manufacturing or quality control problems causing drug substance production and shipment delays or a situation where the contractor may not be able to maintain compliance with the applicable cGMP requirements. Any failure to comply with cGMP requirements or other FDA, EMA and comparable foreign regulatory requirements could adversely affect our clinical research activities and our ability to develop our product candidates and market our products following approval.
 
Our current and anticipated future dependence upon others for the manufacture of our product candidates may adversely affect our future profit margins and our ability to develop our product candidates and commercialize any products that receive regulatory approval on a timely basis.

Risks Relating to Our Intellectual Property
It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.
 
We have been issued patents, applied for other patents, and intend on continuing to seek additional patent protection for our families of antibodies from our antibody development program, our vaccines, methods of use and other compounds that we discover.  However, any or all of such compounds, methods or new uses of known compounds may not be subject to effective patent protection. Further, the development of regimens for the administration of our vaccines, which involve specifications for the frequency, timing and amount of dosages, has been, and we believe may continue to be, important to our efforts, although those processes, as such, may not be patentable. In addition, our issued patents may be declared invalid or our competitors may find ways to avoid the claims in the patents.
 
Our commercial success will depend, in part, on our ability to obtain and maintain patent protection, protect our trade secrets and operate without infringing on the proprietary rights of others. Our commercial success will also depend, in part, on our ability to market our product candidates during the term of our patent protection.  For example, certain patents primarilyincluding in foreign countries within our portfolio expired in 2014 and can no longer be relied on for protection in those countries. As of January 25, 2016,May 11, 2017, we were the exclusive licensee or sole assignee or co-assignee of 1114 granted United States patents, 32 pending United States patent applications, 147 international patents and 319 pending international patent applications.  The patent position of pharmaceutical and biotechnology firms like us are generally highly uncertain and involves complex legal and factual questions, resulting in both an apparent inconsistency regarding the breadth of claims allowed in United States patents and general uncertainty as to their legal interpretation and enforceability.  No absolute policy regarding the breadth of claims allowed in biopharmaceutical patents has emerged to date in the United States or in many foreign jurisdictions. Changes in either the patent laws or in interpretations of patent laws in the United States and foreign jurisdictions may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be enforced in the patents that we currently own or that may be issued from the applications we have filed or may file in the future or that we have licensed or may license from third parties, including MSK for the vaccine antigen patents. Further, if any patents we obtain or license are deemed invalid or unenforceable, it could impact our ability to commercialize or license our technology.  Thus, patent applications assigned or exclusively licensed to us may not result in patents being issued, any issued patents assigned or exclusively licensed to us may not provide us with competitive protection or may be challenged by others, and the current or future granted patents of others may have an adverse effect on our ability to do business and achieve profitability.
 
     One of our issued US patents is directed to a candidate antibody product that will expire in 2034. Other previously filed antibody patent applications will, if issued, have patent expiration dates depending on country and filing date between 2034 and 2035.  It is possible that the term of the antibody patent and certain patents issuing from the antibody patent applications may be extended for a portion of the time the candidate product was under regulatory review. Patents covering components of the sarcoma vaccine will expire in 2022.  Patents covering the polyvalent ovarian vaccine will expire between 2018 and 2025.  We believe that our product candidates are eligible for Orphan Drug designation from FDA depending on the indication for which it is approved by FDA.  Each product that receives an Orphan Drug designation would be eligible for up to 7 additional years of patent protection.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
 
others may be able to make compounds that are similar to our vaccines and monoclonal antibody-based candidates and any future product candidates we may seek to develop but that are not covered by the claims of our patents;
if we encounter delays in our clinical trials, the period of time during which we could market our vaccines and monoclonal antibody-based candidates under patent protection would be reduced;
we might not have been the first to conceive, make or disclose the inventions covered by our patents or pending patent applications;
we might not have been the first to file patent applications for these inventions;
any patents that we obtain may be invalid or unenforceable or otherwise may not provide us with any competitive advantages; or
the patents of others may have a material adverse effect on our business.
 
Due to the patent laws of a country, or the decisions of a patent examiner in a country, or our own filing strategies, we may not obtain patent coverage for all of the product candidates that may be disclosed or methods involving these candidates that may be disclosed in the parent patent application. We plan to pursue divisional patent applications and/or continuation patent applications in the United States and many other countries to obtain claim coverage for inventions that were disclosed but not claimed in the parent patent application, but may not succeed in these efforts.

 
Composition of matter patents on the active biological component are generally considered to be the strongest form of intellectual property protection for biopharmaceutical products, as such patents generally provide protection without regard to any method of use. We cannot be certain that the claims in our patent applications covering composition-of-matter of our candidates will be considered patentable by the U.S. Patent and Trademark Office, or USPTO, courts in the United States or by the patent offices and courts in foreign countries. Method of use patents protect the use of a product for the method recited in the claims. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may infringe or contribute to or induce the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute. Interference proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications or those of our collaborators or licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or interference proceedings may fail, resulting in harm to our business, and, even if successful, may result in substantial costs and distract our management and other employees.
 
There have been numerous changes to the patent laws and proposed changes to the rules of the USPTO, which may have a significant impact on our ability to protect our technology and enforce our intellectual property rights. For example, in September 2011, President Obama signed the America Invents Act that codifies several significant changes to the U.S. patent laws, including, among other things, changing from a “first to invent” to a “first inventor to file” system, limiting where a patent holder may file a patent suit, replacing interference or “first to invent” proceedings with derivation proceedings and creating inter partes review and post-grant opposition proceedings to challenge the validity of patents after they have been issued. The effects of these changes are currently unclear as the USPTO only recently has adopted regulations implementing the changes, the courts have yet to address most of these provisions, and the applicability of the act and new regulations on specific patents and patent applications discussed herein have not been determined and would need to be reviewed.

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number ofmany procedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. In such an event, our competitors might be able to enter the market, which would have a material adverse effect on our business.
 
We also rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, licensees, licensors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information such that our competitors may obtain it. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how, such as new therapies, including therapies for the indications we are targeting. If others seek to develop similar therapies, their research and development efforts may inhibit our ability to conduct research in certain areas and to expand our intellectual property portfolio, and also have a material adverse effect on our business.

 
Moreover, because some of the basic research relating to one or more of our patent applications and/or patents were performed at various universities and/or funded by grants, one or more universities, employees of such universities and/or grantors could assert that they have certain rights in such research and any resulting products. Further, others may independently develop similar products, may duplicate our products, or may design around our patent rights. In addition, as a resultbecause of the assertion of rights by a third-party or otherwise, we may be required to obtain licenses to patents or other proprietary rights of others in or outside of the United States. Any licenses required under any such patents or proprietary rights may not be made available on terms acceptable to us, if at all. If we do not obtain such licenses, we could encounter delays in product market introductions during our attempts to design around such patents or could find that the development, manufacture or sale of products requiring such licenses is foreclosed. In addition, we could incur substantial costs in defending suits brought against us or in connection withabout patents to which we hold licenses or in bringing suitsuing to protect our own patents against infringement.
 
We require employees and the institutions that perform our preclinical and clinical trials to enter into confidentiality agreements with us. Those agreements provide that all confidential information developed or made known to a party to any such agreement during the course of the relationship with us be kept confidential and not be disclosed to third-parties, except in specific circumstances. Any such agreement may not provide meaningful protection for our trade secrets or other confidential information in the event of unauthorized use or disclosure of such information.
 
With respect to our vaccine programs we have in-licensed rights from third parties. If these license agreements terminate or expire, we may lose the licensed rights to some or all of our vaccine product candidates. We may not be able to continue to develop them or, if they are approved, market or commercialize them.
 
We depend on license agreements with third-parties for certain intellectual property rights relating to our product candidates, including, but not limited to, the license of certain intellectual property rights from MSK. In general, our license agreements require us to make payments and satisfy performance obligations in order to keep these agreements in effect and retain our rights under them. These payment obligations can include upfront fees, maintenance fees, milestones, royalties, patent prosecution expenses, and other fees. These performance obligations typically include diligence obligations. If we fail to pay, be diligent or otherwise perform as required under our license agreements, we could lose the rights under the patents and other intellectual property rights covered by these agreements. If disputes arise under any of our in-licenses,license agreements, including our in-licenses fromlicense agreement with MSK, we could lose our rights under these agreements. Any such dispute may not be resolvable on favorable terms, or at all. Whether or not any disputes of this kind are favorably resolved, our management’s time and attention and our other resources could be consumed by the need to attend to these disputes and our business could be harmed by the emergence of such a dispute.
 
If we lose our rights under these agreements, we might not be able to develop any related product candidates further, or following regulatory approval, if any, we might be prohibited from marketing or commercializing these product candidates. In particular, patents previously licensed to us might, after termination of an agreement, be used to stop us from conducting these activities.

We are dependent on MSK for the establishment of our intellectual property rights related to the vaccine program, and if MSK has not established our intellectual property rights with sufficient scope to protect our vaccine candidates, we may have limited or no ability to assert intellectual property rights to our vaccine candidates.

Under our agreement with MSK, MSK was responsible for establishing the intellectual property rights to the vaccine antigen conjugates, mixtures of vaccine antigen conjugates that make up polyvalent vaccine candidates and methods of use. As we were not responsible for the establishment of our intellectual property rights to these vaccine antigen conjugates, mixtures of vaccine antigen conjugates and methods of use, we have less visibility into the strength of our intellectual property rights to our vaccine candidates than if we had been responsible for the establishment of these rights. If MSK did not establish those rights so they are of sufficient scope to protect the vaccine candidates, then we may not be able to prevent others from using or commercializing some or all of our vaccine candidates, and others may be able to assert intellectual property rights in our vaccine candidates and prevent us from further pursuing the development and commercialization of our vaccine candidates.

 
We may not obtain exclusive rights to intellectual property created as a resultbecause of our strategic collaborative agreements.
 
We are party to collaborative research agreements, such as with Heidelberg Pharma GmbH and Rockefeller University and MSK, and expect to enter into agreements with other parties in the future, each of which involve research and development efforts.  Under our existing agreements,certain circumstances, we domay not have exclusive rights to jointly developed intellectual property and would have to license the collaborative partner’s interest in the jointly developed intellectual property to obtain exclusive rights. We may not be able to license our collaborative partner’s interest or license their interest at reasonable terms.  If we are unable to license their interest we would not have exclusive rights to the jointly developed intellectual property and, in some collaborations, the collaborative partner may be free to license their interest in the jointly developed intellectual property to a competitor.  In other collaborations, if we are unable to license the collaborative partner’s interest we may not have sufficient rights to practice the jointly developed intellectual property.  Such provisions to the jointly developed intellectual property may limit our ability to gain commercial benefit from some of or all of the intellectual property we jointly develop with our collaborative partners and may lead to costly or time-consuming disputes with parties with whom we have collaborative relationships over rights to certain innovations or with other third parties that may result from the activities of the collaborative arrangements.
 
We may incur substantial costs as a resultbecause of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to enforce or protect our rights to, or use, our technology.
 
If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or company has the right to ask the court to rule that such patents are invalid or should not be enforced. These lawsuits are expensive and would consume time and resources and divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents or sustaining their validity and enforceability. In addition, there is a risk that the court will decide that such patents are not valid and that we do not have the right to enforce them. There is also the risk that, even if the validity of such patents is upheld, the court will refuse to stop the other party on the grounds that such other party’s activities do not infringe such patents. In addition, the United States Court of Appeals for the Federal Circuit and the Supreme Court of the United States continue to address issues under the United States patent laws, and the decisions of those and other courts could adversely affect our ability to sustain the validity of our issued or licensed patents and obtain new patents.
 
Furthermore, a third party may claim that we or our manufacturing or commercialization partners or customers are using inventions covered by the third party’s patent rights and may go to court to stop us or our partners and/or customers from engaging in our operations and activities, including making or selling our vaccine and monoclonal antibody-based candidates and any future product candidates we may seek to develop. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and scientific personnel. There is a risk that a court would decide that we or our commercialization partners or customers are infringing the third party’s patents and would order us or our partners or customers to stop the activities covered by the patents. In that event, we or our commercialization partners or customers may not have a viable way around the patent and may need to halt commercialization or use of the relevant product. In addition, there is a risk that a court will order us or our partners or customers to pay the other party damages for having violated the other party’s patents or obtain one or more licenses from third parties, which may be impossible or require substantial time and expense. We cannot predict whether any license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In such events, we would be unable to further develop and commercialize one or more of our drug candidates, which could harm our business significantly. In the future, we may agree to indemnify our commercial partners and/or customers against certain intellectual property infringement claims brought by third parties which could increase our financial expense, increase our involvement in litigation and/or otherwise materially adversely affect our business.
 
Because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation, which could adversely affect our intellectual property rights and our business. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.
 
The pharmaceutical and biotechnology industries have produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity or unenforceability is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.

 
Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, because searches and examinations of patent applications by the USPTO and other patent offices may not be comprehensive, and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our patents or pending applications. Our competitors may have filed, and may in the future file, patent applications and may have obtained patents covering technology similar to ours. Any such patents or patent application may have priority over our patent applications, which could further require us to obtain or license rights to issued patents covering such technologies. If another party has obtained a U.S. patent or filed a U.S. patent application on inventions similar to ours, we may have to participate in a proceeding before the USPTO or in the courts to determine which patent or application has priority. The costs of these proceedings could be substantial, and it is possible that our application or patent could be determined not to have priority, which could adversely affect our intellectual property rights and business.
 
We have received confidential and proprietary information from collaborators, prospective licensees and other third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have improperly used or disclosed confidential information of these third parties or our employees’ former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If we are not successful, our ability to continue our operations and our business could be materially, adversely affected.
 
Some of our competitors may be able to sustain the costs of complex intellectual property litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations, on our ability to hire or retain employees, or otherwise on our business.
 
If product liability lawsuits are successfully brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates and any products that we may develop.
 
The testing and marketing of medical products entail an inherent risk of product liability. Although we are not aware of any historical or anticipated product liability claims or specific causes for concern, if we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates and any products that we may develop. In addition, product liability claims may also result in withdrawal of clinical trial volunteers, injury to our reputation and decreased demand for any products that we may commercialize. We currently carry product liability insurance that covers our clinical trials up to a $5.0 million annual aggregate limit. We will need to increase the amount of coverage if and when we have a product that is commercially available. If we are unable to obtain sufficient product liability insurance at an acceptable cost, potential product liability claims could prevent or inhibit the commercialization of any products that we may develop, alone or with corporate partners.
Risks Related to our Common Stock
 
Our restated certificate of incorporation, our amended and restated by-laws and Delaware law could deter a change of our management which could discourage or delay offers to acquire us; certain restrictions in our agreements with existing stockholders could also discourage or delay offers to acquire us.
 
Certain provisions of Delaware law and of our restated certificate of incorporation, as amended, and amended and restated by-laws, could discourage or make it more difficult to accomplish a proxy contest or other change in our management or the acquisition of control by a holder of a substantial amount of our voting stock. It is possible that these provisions could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise consider to be in their best interests or in our best interests. These provisions include:

Additionally, , we granted certain rights to approve future (i) issuances of our securities, (ii) equity or debt financings and (iii) sales of any development product assets currently held by us, subject to certain exceptions, for as long as the Company is prohibited from issuing anylead investor in our August 2016 Public Offering holds 50% or more of the shares of common stock (or Series F Preferred Stock) purchased by the lead investor in the August 2016 Public Offering or until a financing with net proceeds to us of at least $7.5 million in which we are able to sell our securities at a minimum per share price of $7.40 or greater (the “Consent”). In connection with this offering, we have agreed with the lead investor to issue up to 2,900,000 shares of common stock to the August 2016 Investors, as incentive shares to those investors to make a minimum required investment in this public offering of at least 50% of their investment in the $9.4 million August 2016 Public Offering, or the Minimum Required Investment, and who still hold 100% of the shares of common stock. Such August 2016 Investors shall be entitled to receive their pro rata share of 2,900,000 shares, after the lead investor in this offering receives the first 10%. In the event the August 2016 Investors purchased Series F Preferred Stock and make the Minimum Required Investment and who still hold 100% of the shares of Series F Preferred Stock at the closing of this offering, then the conversion rate for the Series F Preferred Stock would change only for those investors making the Minimum Required Investment, resulting in an increase of up to 1,163,291 in the number of shares of common stock that the Series F Preferred Stock may be converted into, assuming all holders of Series F Preferred Stock make the Minimum Required Investment, or from 665,281 to 1,828,572 common share equivalents. In the event of a liquidation, dissolution or winding up of the Company, each share of Series F preferred stock will be entitled to a per share preferential payment equal to the par value of $0.01 per share. There is no adjustment required by the Series F Certificate of Designations as a result of pricing in financings, and is being offered by the Company as an incentive for participation in this financing by the holders of Series F Preferred Stock. Should the Consent be required in connection with future offerings, we may be required again to provide additional consideration, including, but not limited to, consideration in the form of cash and/or additional shares of our capital stock and/or securities convertible into common stock, enter into any equity line of credit or issue any floating or variable priced equity linked instrument without the consent of a certain recipient of Exchange Securities until the earlier to occur of: (a) April 1, 2017; (b) the date on which the Company has raised $10 million in equity financing; (c) the date on which the Company has closed one or more licensing agreements with corporate partners pursuant to which the Company is entitled to receive in total a minimum of $10,000,000 in initial licensing or equity investments under such agreements; and (d) the date on whichexercisable for shares of our capital stock, in order to obtain the Company's common stockConsent.  If we are listed on a national securities exchange.  It is possible that these provisionsunable to obtain the Consent when necessary for future offerings, we may be unable to raise additional funds. An inability to raise additional funds could make it more difficult to accomplish, or could deter, transactions that stockholders may otherwise consider to be in their best interests or in our best interests.
The price of our common stock is volatile, and is likely to continue to fluctuate due to reasons beyond our control.
The market price of our common stock has been, and likely will continue to be, highly volatile. Factors, including our financial results or our competitors’ financial results, clinical trial and research development announcements and government regulatory action affecting our potential products in both the United States and foreign countries, have had, and may continue to have a significantmaterial adverse effect on our financial condition, results of operations, ability to conduct our business and on the market price of our common stock. We cannot assure you thathave also granted the lead investor in this offering certain rights to approve future (i) issuances of our securities, (ii) equity or debt financings and (iii) sales of any investmentdevelopment product assets currently held by us, subject to certain exceptions, if such securities are sold at price below $2.50 per share and for as long as the lead investor in the offering holds 50% or more of the shares of Series G Preferred Stock purchased by a lead investor in this offering.  The August 2016 Investors who still hold 100% of their shares from the August 2016 Public Offering and make the Minimum Required Investment in this offering in order to receive a portion of the 2,900,000 shares, will have their outstanding warrants, exercisable at a price of $5.55 and $6.29, respectively, from the August 2016 Public Offering, cancelled.
Unless our common stock will not fluctuate significantly. One or more of these factors could significantly harm our business and cause a decline in the price of our common stock in the public market. Sales of shares of common stock registered for resale or eligible for resale pursuant to Rule 144 under the Securities Act as amended, as well as future sales of our common stock by existing stockholders, or the perception that sales may occur at any time, could adversely affect the market price of our common stock.
Substantial future sales of our common stock by us or by our existing stockholders could cause our stock price to fall.
Additional equity financingsis listed on The NASDAQ Capital Market or other share issuances by us, including shares issued in connection with strategic alliances and corporate partnering transactions, could adversely affect the market price of our common stock. Sales by existing stockholders of a large number of shares of our common stock in the public market or the perception that additional sales could occur could cause the market price of our common stock to drop.
If we do not progress in our programs as anticipated, our stock price could decrease.
For planning purposes, we estimate the timing of a variety of clinical, regulatory and other milestones, such as when a certain product candidatenational securities exchange, it will enter clinical development, when a clinical trial will be completed or when an application for regulatory approval will be filed. Our estimates are based on present facts and a variety of assumptions. Many of the underlying assumptions are outside of our control. If milestones are not achieved when we estimated that they would be, investors could be disappointed, and our stock price may decrease.

Our common stock is deemed a “penny stock,” which would make it more difficult for our investors to sell their shares.
 
OurOn August 17, 2016, we began trading on The NASDAQ Capital Market. If we fail to maintain our listing on The NASDAQ Capital Market or other national securities exchange, our common stock iswill be subject to the “penny stock” rules adopted under Section 15(g) of the Exchange Act. The penny stock rules generally apply to companies whose common stock is not listed on the NASDAQ StockCapital Market or other national securities exchange and trades at less than $4.00 per share, other than companies that have had average revenue of at least $6,000,000 for the last three years or that have tangible net worth of at least $5,000,000 ($2,000,000 if the company has been operating for three or more years). These rules require, among other things, that brokers who trade penny stock to persons other than “established customers” complete certain documentation, make suitability inquiries of investors and provide investors with certain information concerning trading in the security, including a risk disclosure document and quote information under certain circumstances. Many brokers have decided not to trade penny stocks because of the requirements of the penny stock rules and, as a result, the number of broker-dealers willing to act as market makers in such securities is limited. If we remain subject to the penny stock rules for any significant period, it could have an adverse effect on the market, if any, for our securities. If our securities are subject to the penny stock rules, investors will find it more difficult to dispose of our securities.securities.
Additionally, in order for our Company to continue trading on the NASDAQ Capital Market, we must maintain compliance with all of the criteria under at least one of the three continued listing standards: the Equity Standard, which includes a requirement for $2.5 million in stockholders’ equity; the Market Value of Listed Securities Standard, which includes a requirement for a market value of listed securities of at least $35 million; or the Net Income Standard, which includes a requirement for net income of at least $500,000 from continuing operations in the latest fiscal year or in two of the last three fiscal years. As of March 31, 2017, which is prior to a private placement of $850,000 in Series H Preferred Stock on May 3, 2017, and prior to this offering, we met none of the three standards. Following receipt of funds from our private placement on May 3, 2017 and this offering, we believe we will be able to meet the Equity Standard for June 30, 2017. However, for future periods if we do not have a market value of listed securities of at least $35 million, or do not meet the Equity Standard, then we may have to enter into a license agreement on less favorable terms to generate near term revenues, or raise additional capital, which could be dilutive to the Company.

Our stock prices and the market prices for securities of biotechnology companies in general have been highly volatile, with recent significant price and volume fluctuations, and may continue to be highly volatile in the future. For example, during the year ended December 31, 2015,2016, our common stock traded between $0.61$3.03 per share and $4.94$6.51 per share. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock, some of which are beyond our control:
 
developments regarding, or the results of, our clinical trials;
announcements of technological innovations or new commercial products by our competitors or us;
our issuance of equity or debt securities, or disclosure or announcements relating thereto;
developments concerning proprietary rights, including patents;

A limited public trading market may cause volatility in the price of our common stock.
 
OurOn August 17, 2016, we began trading on The NASDAQ Capital Market. If we fail to maintain the listing of our common stock is currentlyon The NASDAQ Capital Market, our common stock will be quoted on the OTCQB marketplace.  The quotation of our common stock on the OTCQB marketplace does not assure that a meaningful, consistent and liquid trading market currently exists, and in recent years such market has experienced extreme price and volume fluctuations that have particularly affected the market prices of many smaller companies like us. Our common stock is subject to this volatility. Sales of substantial amounts of common stock, or the perception that such sales might occur, could adversely affect prevailing market prices of our common stock and our stock price may decline substantially in a short time and our stockholders could suffer losses or be unable to liquidate their holdings. BecauseIf our common stock does not trade on a national securities exchange in the future, our common stock iswill be subject to the securities laws of the various states and jurisdictions of the United States in addition to federal securities law. While we may register our common stock or qualify for exemptions for our common stock in one of more states, if we fail to do so the investors in those states where we have not taken such steps may not be allowed to purchase our stock or those who presently hold our stock may not be able to resell their shares without substantial effort and expense. These restrictions and potential costs could be significant burdens on our stockholders.stockholders.

 
We may not be able to achieve secondary trading of our stock in certain states because our common stock is no longer nationally traded, which could subject our stockholders to significant restrictions and costs.-20-
Our common stock is not currently eligible for trading on The NASDAQ Capital Market or on a national securities exchange. Therefore, our common stock is subject to the securities laws of the various states and jurisdictions of the United States in addition to federal securities law. While we may register our common stock or qualify for exemptions for our common stock in one of more states, if we fail to do so the investors in those states where we have not taken such steps may not be allowed to purchase our stock or those who presently hold our stock may not be able to resell their shares without substantial effort and expense. These restrictions and potential costs could be significant burdens on our stockholders.

Reverse Stock Split; Uplisting Risk.
On August 26, 2015, stockholders of the Company approved a proposal to grant the Board of Directors authority to effect a reverse stock split of the Company’s issued and outstanding common stock by a range of 1 share for every 2 shares of common stock outstanding and up to 1 share for every 4 shares of common stock outstanding. The Board of Directors has not determined as of the date of this prospectus to approve any reverse split. NASDAQ and other national securities exchanges require a minimum price per share of common stock for listing of the Company’s common stock and approval of a reverse split is in the discretion of the Board of Directors. Accordingly, the price of the Company’s common stock would have an impact on the Company’s ability to list or timing of such listing on any national securities exchange.

The number of shares of issued and outstanding common stock represents approximately 46%38% of our fully diluted shares of common stock. Additional issuances of shares of common stock upon conversion and/or exercise of preferred stock, options to purchase common stock and warrants to purchase common stock will cause substantial dilution to existing stockholders.

At January 25, 2016,May 11, 2017, we had 29,036,2726,434,348 shares of common stock issued and outstanding. Up to an additional 21,837,2003,461,138 shares may be issued upon conversion of our Series D Preferred Stock, Series E Preferred Stock, Series F Preferred Stock and Series E ConvertibleH Preferred Stock; 8,876,336Stock, 5,125,391 shares issuable upon exercise of warrants at a weighted average price of $1.33; 3,263,041$6.84, 1,598,071 shares upon exercise of all outstanding options and to purchase our common stock at ana weighted average price of $2.36;$7.27, and 2,300,850107,240 shares issuable upon vesting of restricted stock units granted, which amounts includes all reserves, resulting in a total of up to 65,313,69916,726,188 shares that may be issued and outstanding, assuming conversion of all outstanding convertible preferred stock, and exercise of all outstanding option and warrants to purchase our common stock.outstanding. The issuance of any and all of the 36,277,42710,291,840 shares issuable upon exercise or conversion of our outstanding convertible securities will cause substantial dilution to existing stockholders and may depress the market price of our common stock.
You may experience future dilution in the event of future equity offerings
 
We may in the future offer shares of our common stock or other securities convertible into or exchangeable for our common stock.  Although no assurances can be given that we will consummate a financing, in the event we do, or in the event we sell shares of common stock or other securities convertible into shares of our common stock in the future, additional and substantial dilution will occur.  In addition, investors purchasing shares or other securities in the future could have rights superior to our current shareholders. Further, in the event we must again obtain the Consent, you may experience additional dilution if we are required to issue additional shares of our capital stock and/or securities convertible into or exercisable for shares of our capital stock.
Risks Related to the Offering
You will experience immediate and substantial dilution.
Since the public offering price of the securities offered pursuant to this prospectus is higher than the net tangible book value per share of our common stock, you will suffer substantial dilution in the net tangible book value of the common stock you purchase in this offering. See “Dilution” in this prospectus for a more detailed discussion of the dilution you will incur if you purchase securities in this offering. In the event that you exercise your warrants, you will experience additional dilution to the extent that the exercise price of the warrants is higher than the tangible book value per share of our common stock.  In addition, we may have issued options and warrants to acquire common stock at prices below the expected public offering price of the shares of common stock offered hereby, although no warrants at the present time are below the current offering price. To the extent outstanding options, warrants or other derivative securities are ultimately exercised or converted, or if we issue restricted stock to our employees under our equity incentive plans, there will be further dilution to investors who purchase shares in this offering. As previously disclosed, you will experience dilution as a result of the additional shares issued the investors in the August 2016 Offering as a condition for obtaining the Consent.
Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use these proceeds effectively.
We have not designated any portion of the net proceeds from this offering to be used for any particular purposes. Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. Our failure to apply these funds effectively could have a material adverse effect on our business, delay the development of our product candidates and cause the price of our common stock to decline.
You will experience future dilution as a result of future equity offerings
 
We may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock.  Although no assurances can be given that we will consummate a financing, in the event we do, or in the event we sell shares of common stock or other securities convertible into shares of our common stock in the future, additional and substantial dilution will occur.  In addition, investors purchasing shares or other securities in the future could have rights superior to investors in this offering.
Further, in the event we must again obtain the Consent, you may experience additional dilution if we are required to issue additional shares of our capital stock and/or securities convertible into or exercisable for shares of our capital stock.
If we are not able to comply with the applicable continued listing requirements or standards of NASDAQ, NASDAQ could delist our common stock.
On August 17, 2016, we began trading on The NASDAQ Capital Market. In order to maintain that listing, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders’ equity, minimum share price, and certain corporate governance requirements. There can be no assurances that we will be able to comply with the applicable listing standards.
In the event that our common stock is delisted from the NASDAQ Capital Market and is not eligible to be listed on another national securities exchange, trading of our common stock could be conducted in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTCQB. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on a major exchange.
If our common stock is not listed on a national securities exchange, compliance with applicable state securities laws may be required for subsequent offers, transfers and sales of the shares of common stock offered hereby.
The securities offered hereby are being offered pursuant to one or more exemptions from registration and qualification under applicable state securities laws. Because our common stock is listed on The NASDAQ Capital Market, we are not required to register or qualify in any state the subsequent offer, transfer or sale of the common stock. If our common stock is delisted from The NASDAQ Capital Market and is not eligible to be listed on another national securities exchange, subsequent transfers of the shares of our common stock offered hereby by U.S. holders may not be exempt from state securities laws. In such event, it will be the responsibility of the holder of shares or warrants to register or qualify the shares for any subsequent offer, transfer or sale in the United States or to determine that any such offer, transfer or sale is exempt under applicable state securities laws.

PRICEUSE OF PROCEEDS
We estimate that the net proceeds of this offering will be approximately $4.0 million, or approximately $4.4 million if the underwriter exercises its over-allotment option in full, assuming the sale of 1,657,143 shares, or 1,905,714 shares assuming exercise over-allotment option, of our common stock and 1,000,000 shares of Series G Preferred Stock at an assumed public offering price of $1.75 per share, after deducting the estimated underwriting discount and estimated offering expenses payable by us.
 A $0.25 increase (decrease) in the assumed public offering price of $1.75 per share would increase (decrease) the expected net proceeds of this offering by approximately $649,000, assuming the number of shares offered by us remains the same and after deducting the estimated underwriting discount and estimated offering expenses payable by us. A 100,000 increase (decrease) in the assumed number of shares of our common stock sold in this offering would increase (decrease) the expected net proceeds of this offering by approximately $162,000, assuming the assumed public offering price per share remains the same.

EQUITY COMPENSATION PLAN INFORMATION
-23-
The following table provides certain information with respectDILUTION
If you purchase shares of our common stock or Series G Preferred Stock in this offering, you will experience dilution to allthe extent of the Company’s equity compensation plansdifference between the price per share you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. The net tangible book value of our common stock on December 31, 2016, on a pro forma basis after including the proceeds of the May 3rd Private Placement, was approximately $(2.6 million), or approximately $(0.42) per share. Net tangible book value per share is equal to the amount of our total tangible assets, less total liabilities, divided by the aggregate number of shares of our common stock outstanding.
After giving effect to the assumed sale by us of 1,657,143 shares of our common stock and 1,000,000 shares of Series G Preferred Stock in this offering at an assumed public offering price of $1.75 per share and the issuance of 2,900,000 shares of common stock to the August 2016 Investors who make a minimum required investment in this public offering of at least 50% of their investment in the August 2016 Public Offering and who still hold 100% of the shares they received in the August 2016 Public Offering, and after deducting the estimated underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2015.2016, would have been approximately $1.3 million, or approximately $0.12 per share. This represents an immediate increase in net tangible book value of approximately $0.54 per share to existing stockholders and an immediate dilution of approximately $1.63 per share to new investors purchasing shares of our common stock in this offering. The following table illustrates this per share dilution:
Assumed public offering price per share1.75
Proforma Net tangible book value per share as of December 31, 2016 including the May 3rd Private Placement
(0.42)
Increase in net tangible book value per share attributable to this offering0.54
Pro forma as adjusted net tangible book value per share after this offering
0.12
Dilution in pro forma net tangible book value per share to new investors1.63
  A $0.25 increase in the assumed public offering price of $1.75 per share would increase our as adjusted net tangible book value after this offering by approximately $649,000, or approximately $0.06 per share, and increase the dilution to new investors by approximately $0.19 per share, assuming that the number of shares of common stock offered by us, as set forth above, remains the same and after deducting the estimated underwriting discount and estimated offering expenses payable by us.  A $0.25 decrease in the assumed public offering price of $1.75 per share would decrease our as adjusted net tangible book value after this offering by $649,000, or approximately $0.06 per share, and decrease the dilution per share to new investors by approximately $0.19 per share, assuming that the number of shares of common stock offered by us, as set forth above, remains the same and after deducting the estimated underwriting discount and estimated offering expenses payable by us.  We may also increase or decrease the number of shares of common stock we are offering from the assumed number of shares set forth above. An increase (decrease) of 100,000 in the assumed number of shares of common stock sold in this offering would increase (decrease) our as adjusted net tangible book value after this offering by approximately $162,000, or approximately $0.01 per share, and increase (decrease) the dilution per share to new investors by approximately $0.01 per share, assuming that the public offering price of $1.75 per share remains the same. The information discussed above is illustrative only and will adjust based on the actual public offering price, the actual number of shares of common stock that we offer in this offering, and other terms of this offering determined at pricing.
If the underwriter exercises in full its option to purchase 248,571 additional shares in full at the assumed public offering price of $1.75 per share, the as adjusted net tangible book value of our common stock after this offering would increase from $0.12 per share to $0.15 per share, representing an immediate increase in net tangible book value of approximately $0.03 per share to existing stockholders and would decrease this dilution by $0.03 per share to the investors in this offering, after deducting the underwriting discount and estimated offering expenses payable by us.
This table does not take into account further dilution to new investors that could occur upon the exercise of outstanding options and warrants having a per share exercise price less than the public offering price per share in this offering.  In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.
                The table and discussion above are based on 6,296,110 shares outstanding as of December 31, 2016, and exclude as of that date:
851,375 shares of our common stock issuable upon exercise of outstanding options under our equity incentive plans at a weighted-average exercise price of $10.94 per share;

MANAGEMENT’SMANAGEMENT’S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of operations should be read together with our consolidated financial statements and accompanying notes appearing elsewhere in this Prospectus. This Management’s Discussion and Analysis contains forward-looking statements that involve risks and uncertainties. Please see “Forward-Looking“Cautionary Note Regarding Forward-Looking Statements” set forth in the beginningon page 22 of this Prospectus, and see “Risk Factors” beginning on page 56 for a discussion of certain risk factors applicable to our business, financial condition, and results of operations. Operating results are not necessarily indicative of results that may occur in future periods. Management and our independent registered public accounting firm identified certain material weaknesses in internal control over financial reporting. If we are unable to remediate these material weaknesses and maintain effective internal control, we may not be able to produce timely and accurate financial statements, and we and our independent registered public accounting firm could conclude that our internal control over financial reporting are not effective, which could adversely impact investor confidence and our stock price. See "Risk Factors" on page 5.

Overview
 
We have been engaged in the discovery development and commercializationdevelopment of proprietary human monoclonal antibody products and vaccines for the diagnosis and treatment of a variety of cancers. We have discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunizedvaccinated against targeted cancers. Therapeutic vaccines under development were discovered at Memorial Sloan Kettering Cancer Center, or MSK, and are exclusively licensed to MabVax Therapeutics. We operate in only one business segment.
We have incurred netsubstantial losses since inception, and we expect to incur additional substantial losses for the foreseeable future as we continue our research and development activities. To date, we have funded our operations primarily through government grants, proceeds from the sale of common and preferred stock, equity securities, non-equitythe issuance of debt, the issuance of common stock in lieu of cash for services, payments from collaborators and interest income.  The process of developing our productsproduct candidates will require significant additional research and development, preclinical testing and clinical trials, as well as regulatory approval. We expect these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. We will not receive product revenue unless we, or our collaborative partners, complete clinical trials, obtain regulatory approval and successfully commercialize one or more of our products.

During  We cannot provide assurance that we will ever generate revenues or achieve and sustain profitability in the nine months ended September 30, 2015,future or obtain the necessary working capital for our loss from operations was $14,142,645 and our net loss was $14,123,107. Net cash used in operations for the nine months ended September 30, 2015 was $7,917,332 and cash and cash equivalents as of September 30, 2015 was $4,538,680. As of September 30, 2015, we had an accumulated deficit of $56,619,570. operations.
 
During the year ended December 31, 2014,2016, our loss from operations was $8,392,896$16,663,119 and our net loss was $7,917,853.$17,660,483. Net cash used in operating activities for the year ended December 31, 20142016 was $7,662,019$12,363,411 and cash and cash equivalents at December 31, 20142016 were $1,477,143.$3,979,290. As of December 31, 2014,2016, we had an accumulated deficit of $24,550,308.$78,262,261.
 
We are subject to risks common to biopharmaceutical companies, including the need for capital, risks inherent in our research, development and commercialization efforts, preclinical testing, clinical trials, uncertainty of regulatory and marketing approvals, enforcement of patent and proprietary rights, potential competition and retention of key employees. In order for a product to be commercialized, it will be necessary for us to conduct preclinical tests and clinical trials, demonstrate efficacy and safety of our product candidates to the satisfaction of regulatory authorities, obtain marketing approval, enter into manufacturing, distribution and marketing arrangements, obtain market acceptance and, in many cases, obtain adequate reimbursement from government and private insurers. We cannot provide assurance that we will ever generate revenues or achieve and sustain profitability in the future or obtain the necessary working capital for our operations.


Merger Agreement
Upon the terms and subject to the satisfaction of the conditions described in the Agreement and Plan of Merger, dated May 12, 2014, as amended on June 30, 2014 and July 7, 2014 (the “Merger Agreement”), on July 8, 2014, Tacoma Corp. was merged with and into MabVax Therapeutics, with MabVax Therapeutics surviving the Merger as our wholly-owned subsidiary. The Merger closed and became effective on July 8, 2014. All shares of MabVax Therapeutics Series A preferred stock and MabVax Therapeutics Series B preferred stock were automatically converted into shares of our common stock immediately prior to the Merger. Upon the effective date of the merger (a) all outstanding shares of MabVax Therapeutics common stock were converted into and exchanged for shares of our common stock at an exchange rate calculated in accordance with the methodology set forth in the Merger Agreement, which resulted in the issuance of 2.223284 shares of our common stock for every share of MabVax Therapeutics common stock, (b) all outstanding shares of MabVax Therapeutics Series C-1 preferred stock were converted into and exchanged for shares of our Series A-1 preferred stock at a rate of two shares of MabVax Therapeutics Series C-1 preferred stock per each share of our Series A-1 preferred stock, (c) each outstanding MabVax Therapeutics option and warrant to purchase MabVax Therapeutics common stock became options and warrants to purchase our common stock (and the number of such shares and exercise price was adjusted as calculated in accordance with the methodology set forth in the Merger Agreement), and (d) each outstanding MabVax Therapeutics warrant to purchase MabVax Therapeutics preferred stock was cancelled for no consideration.
As a result of the consummation and upon the closing of the Merger, the former stockholders, option holders and warrant holders of MabVax Therapeutics were issued, based on the methodology set forth in the Merger Agreement (which excluded certain out of the money convertible securities and calculated others on a net-exercise or cashless basis under the terms of the convertible securities), approximately 85% of the outstanding shares of our common stock on a fully diluted basis and our stockholders, option holders and warrant holders immediately prior to the merger owned approximately 15% of the outstanding shares of our common stock on a fully diluted basis (such percentages calculated based on the methodology set forth in the Merger Agreement). As a result of the Merger, we underwent a change in control.
The total consideration for the transaction was approximately $6,416,000, based on the market price of our common stock, since management has determined that this was the most reliable measure of fair value.
The issuance of shares of our common stock and preferred stock in the Merger were approved by our stockholders in the stockholders’ meeting held on July 7, 2014. The amendments to our amended and restated certificate of incorporation related to an increase in the authorized number of shares of our common and preferred stock and a potential reverse stock split to meet the initial NASDAQ listing standards required as a result of the Merger and other transactions contemplated by the Merger Agreement were not approved at such meeting.
 
Reverse Stock Split Name Change and IncreaseListing on NASDAQ
On August 16, 2016, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware in Authorized Shares

In a subsequent special stockholders meeting held on September 8, 2014 our stockholders approved, among other items, authorization for our Board of Directorsorder to effectuate a reverse stock split in the ratio range of 5:our issued and outstanding common stock on a 1 to 15:1. Following the stockholders meeting, our Board of Directors approved afor 7.4 basis, effective on August 16, 2016 The reverse split was effective with The Financial Industry Regulatory Authority (FINRA), and the Company’s common stock began trading on The NASDAQ Capital Market at the open of 8:1, or the Reverse Split. The stockholders also approvedbusiness on August 17, 2016. All share and our Board of Directors implemented an amendment to our amendedper share amounts, and restated certificate of incorporation to change our name from “Telik, Inc.” to “MabVax Therapeutics Holdings, Inc.” and to increase the authorized number of shares of ourcommon stock into which each share of preferred stock will convert, in the financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Listing Reverse Split, including reclassifying an amount equal to the reduction in par value of common stock to a new total of 150,000,000 and our authorized number of preferred shares to a new total of 15,000,000.additional paid-in capital.

 
Our Clinical Product Development- Recent UpdatesDevelopment Programs and Plans for 2017
 
PhaseMVT-5873 – for the Treatment of Pancreatic Cancer
In our progress report released in November 2016, we stated that the safety of our HuMab-5B1 antibody designated as MVT-5873 had been established at three incremental dose levels in our phase I Clinical Trialclinical trial. The purpose of HuMab 5B1 – In December 2015, we received notice from the U.S. Food and Drug Administration (FDA) authorizing the initiation a Phasethis phase I clinical trial, with HuMab 5B1 as a therapeutic treatment for pancreatic cancer.  We filed an Investigational New Drug (IND) application for our lead fully human antibody product on November 30, 2015.  Patient enrollmentinitiated in the Phase I clinical trialFebruary 2016, is expected to begin at multiple investigational sites in the first quarter of 2016.  The Phase I trial will evaluate theestablish safety and tolerability, and pharmacokineticsto determine the recommended phase II dose for patients with locally advanced and metastatic pancreatic cancer or other malignancies expressing the same cancer antigen known as CA19-9. Patients entering this part of HuMab 5B1 as a single agent orthe trial were stage three and stage four cancer patients who had failed all previous treatments, and had progressive disease.
Study protocol allows patients to remain on therapy beyond the initial 28-day treatment and safety assessment cycle based on acceptable dose tolerability and investigator assessment of continued benefit from the treatment. Every second treatment cycle the investigator assesses disease status using RECIST 1.1 measurement criteria to evaluate tumor response rate and duration of response.
After establishing the current dosage safety level for MVT-5873 in combinationPart 1 of the trial, we were able to initiate part 2 of our phase I study. Part 2 combines MVT-5873 with a standard of care chemotherapy regimen in subjects with metastatic pancreatic cancer.newly diagnosed treatment naïve patients. The first cohort of patients will be enrolleddosage levels established in a traditionalour MVT-5873 monotherapy trial also have cleared all subsequent dose escalation regimen to assess safety and determine the optimal dose of the antibody.  A second patient cohort will establish the safety and optimized dose of the antibody when administered with a standard of care chemotherapy.   Two additional patient cohorts will be administered the optimized dose of antibody as a single agent, orlevels utilized in combination with a standard of care chemotherapy regimen, for the treatment of patients with pancreatic cancer.

Phase I Clinical Trial of 89Zr-HuMab-5B1 – In January 2016, we filed an IND application with the FDA for 89Zr-HuMab-5B1, utilizing our fully human antibody product as a new generation PET scan cancer imaging agent.  Subject to FDA authorization to proceed, we plan to initiate the Phase I clinical study of MVT-2163 as an immuno-PET imaging agent as well as the dose levels planned for our clinical study of our radioimmunotherapy product MVT-1075 that combines MVT-5873 with a radioactive substance.
Recent progress – As of April 2017, we had enrolled 29 patients in Part 1 of our phase I trial at three clinical sites. Twenty-five patients are currently evaluable. We have seen an efficacy signal from early study results primarily in patients who enter the trial with pancreatic cancerCA19-9 levels below 2,500 U/ml. In this group of patients, we observed that the first cycle of treatment with MVT-5873 reduces CA19-9 levels by 95% or more and close to normal levels. We also observed that approximately half of the patients with CA19-9 levels below 2,500 U/ml. convert from progressive disease to stable disease. Further, approximately 30% of this responder set maintained stable disease for four or more months. Patients continue to tolerate the study drug reasonably well with drug infusion reactions being the most common adverse event which is adequately addressed by slowing the infusion rate and use of routine premedication. Increases in liver function tests are seen early 2016.  The 89Zr-HuMab-5B1 imaging agent has demonstrated high-resolution imagesin a minority of tumors in xenograft animal models, potentially making it an important new toolpatients and appear reversible.
Plan for remainder of 2017 – We plan to aidconduct a small phase Ib study in the diagnosis, monitoring and assessmentsecond half of 2017 to evaluate the use of MVT-5873 as a maintenance therapy for pancreatic cancer patients whose chemotherapy treatments no longer provide improvement and are experiencing increasing levels of toxicity. We believe we can demonstrate proof-of-concept for this approach with a small cohort of approximately 10 patients. Results from this study are anticipated around year end 2017.
MVT-2163 –as an attractive companion diagnosticImaging Agent for the HuMab-5B1 therapeutic product. This second planned Phase I trial will evaluate thePancreatic Cancer
In our progress report released in November 2016, we stated that we had established interim safety, and acceptable pharmacokinetics and biodistribution of our immuno-PET imaging agent that we designate as MVT-2163 in our phase I clinical trial. MVT-2163 is comprised of MVT-5873 conjugated to a radio label. We have completed the initial two cohorts of patients as specified in our protocol. In the first cohort, we administered MVT-2163 alone and in the second cohort we administered MVT-2163 following a blocking dose of MVT-5873. We reported that the initial PET images demonstrated target specificity by correlation with lesions identified by conventional computerized tomography (CT) scans. The biodistribution data obtained in the first two cohorts demonstrated improvement in PET images by pre-administration of MVT-5873, as has been observed with other antibody based PET agents. We initiated the MVT-2163 phase I trial in June 2016 to evaluate a next generation diagnostic PET imaging agent in patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies. MVT-2163 (89Zr-HuMab-5B1) combines the well-established PET imaging radiolabel Zirconium [Zr-HuMab-5B1 in cancer patients.  The89Zr] with the targeting specificity of MVT-5873. We designed the trial will also determineto establish safety, pharmacokinetics, biodistribution, optimal time to obtain the ideal dosePET image, and conditions for an optimalthe amount of MVT-5873 to be used prior to administration of MVT-2163 to obtain optimized PET scan image usingimages. We continue to actively recruit patients and expect to establish the new imaging agent.

Vaccines – Our therapeutic vaccines were developed at MSK and are exclusively licensed to MabVax Therapeutics pursuant to agreements entered into by and between MabVax Therapeutics and MSKoptimal co-administration dose of MVT-5873 early in 2008. These vaccines are administered in the adjuvant setting and have shown to elicit a protective antibody response in clinical studies. The antibodies are intended to seek out circulating tumor cells and micrometastases to kill them before they can cause cancer recurrence. Our lead cancer vaccines targeting recurrent sarcoma and ovarian cancer are currently in proof of concept Phase II multi-center clinical trials. Both trials have received substantial federal grant monies to support their development.2017.
 
Preclinical Drug Product Development
-26-
Recent progress – As of April of 2017 we had completed enrollments in the phase 1a portion of our study in all three planned cohorts. We have expanded cohort 3 to evaluate not only an increased blocking dose but the impact of expanding the time interval between the administration of a blocking dose and the MVT-2163 PET agent. We have determined that a 47 mg. blocking dose and a time interval of 2 to 4 hours significantly improves the quality of the PET scan image. We observed that the blocking dose helps to reduce theaccumulation of labeled antibody in the liver and spleen while also improving accumulation of the labeled antibody on both tumor and metastatic sites. Images seen from use of MVT-2163 appear to be identifying smaller metastatic sites that are below the limit of detection with CT scans.
Plan for remainder of 2017 – In consultation with our clinical investigators, we plan to expand our phase 1 program for the remainder of 2017 to include additional patients who will consent to have the smaller potential metastatic sites being seen with MVT-2163 images biopsied to provide evidence that MVT-2163 is identifying previously unseen disease. Better understanding of the extent and spread of the cancer will significantly improve the clinical decision regarding eligibility for curative surgery. We expect to have results of biopsies later in 2017.
MVT-1075 –as a Radioimmunotherapy for Pancreatic Cancer
 
We are developing the HuMab 5B1 antibodyHuMab-5B1 into a third potential product for use as a radio-immunotherapyradioimmunotherapy that we have designated as MVT-1075. MVT-1075 represents a unique product opportunity for MabVax by conjugating MVT-5873 with a low-energy radiation emitter, 177Lu, which has a relatively short tissue penetration range to minimize potential side effects of the radiation. MVT-5873 provides the opportunity for tumor-specific targeting of a more potent analog of MVT-5873. We submitted our IND in late December 2016, and the IND was authorized to proceed on January 27, 2017. We plan to initiate the phase I trial of MVT-1075 in the first half of 2017. 
Historical Information on Work Conducted on Cancer Vaccines– From 2010 to 2015, we and our collaborative partners were engaged in enrolling patients in two phase II multi-center clinical trials of cancer vaccines that targeted recurrent sarcoma (soft tissue cancer) and ovarian cancer.  In 2015, all vaccinations in the two studies had been completed, and since then, we and are partners have been engaged in the monitoring of patients to assess overall survival, or OS. Both the sarcoma and ovarian cancer vaccine trials were randomized, double-blind, multicenter phase II trials that had enrolled 136 and 164 patients respectively.  Both trials were designed to yield statistically significant evidence that vaccination of trial subjects can provide 50% improvement in progression free survival, or PFS, and extend OS.  We and our collaboration partners in these studies are no longer performing significant work on these studies other than to monitor patients for OS. 
An independent Drug Safety and Monitoring Board, or DSMB, composed of experts in the field analyzed the sarcoma clinical trial data in March of 2013 and determined that the PFS endpoint of a 50% increase in the time to progression was not reached. At the suggestion of the DSMB we have continued to monitor patients for OS and plan to issue a final report on our findings in 2017.   The National Institutes of Health, or NIH, approved a grant of $1.75 million that we received in progress payments between 2014 and 2016 to help offset the clinical trial costs for the treatmentsarcoma trial. We have no plans at this time to engage in additional clinical studies for this vaccine.

At the American Society of pancreatic cancer.Clinical Oncology meeting in June 2016 the sponsors of the Phase II trial in ovarian cancer, the Gynecologic Oncology Group, or GOG, a consortium of clinical trial investigators and sites working in collaboration with the NCI, reported that the primary endpoint of improvement in PFS was not reached. We also are evaluating anti-GD2 antibody candidatessuggested that the GOG continue to monitor the trial subjects in the ovarian cancer vaccine trial for selection ofOS. The ovarian vaccine trial has been fully funded by a lead development candidategrant from the NIH. We have no financial obligation for further preclinical development.this trial or the follow-on monitoring.  If the OS endpoint were to be achieved, we would pursue out-licensing the product.  We have no plan at this time to engage in additional clinical studies for this vaccine.

For the year ended December 31, 2014, MabVax Therapeutics recognized revenues of $314,175, as compared to $366,368 for the same period in the prior year. This decrease was primarily due to less work performed on grant contracts in 2014 as compared to work performed on grants in 2013. Revenues earned in 2014 were from the NIH Imaging Contract, which began on September 20, 2013 and continued in 2014 with a Phase II portion of the SBIR contract from NCI being awarded for $1.5 million. Revenues for 2013 represent both the work performed under the NIH imaging contract starting in September 2013, as well as work performed in connection with the remainder of a Phase II NIH grant to support the NCI sarcoma vaccine trial for a vaccine intended to prevent the recurrence of sarcoma, or the NCI Sarcoma Vaccine Grant.

Gallus BioPharmaceuticals). In addition, during the year ended December 31, 2016 the Company negotiated a release of approximately $363,000 of previously accrued manufacturing costs in connection with the sarcoma vaccine trial as well as the initial contract expenses under the NIH Imaging Contract.related to failed manufacturing batches.

We expect our total research and development expenditures in the next twelve months to increase as we continue GMP manufacturing of 5B1 and producing finished clinical drug product and perform GLP toxicology studies. We are seeking additional capital to fund the initial clinical studystudies of 5B1MVT-5873 and MVT-2163 and begin clinical trials in humans intended to start laterMVT-1075 in 2015.2017. In the event we are unable to obtain sufficient funding for clinical development of 5B1,our therapies, we will need to defer the startcompletion of clinical trials or reduce the scope of the trials until such funding is in place. If we are unable to obtain additional funding for 5B1,our trials to complete clinical development, our total research and development expenditures will decrease substantially until the additional funding is raised.
 
The process of conducting the clinical research necessary to obtain FDA approval is costly and time consuming. Current FDA requirements for a new human drug to be marketed in the United States include:
the successful conclusion of preclinical laboratory and animal tests, if appropriate, to gain preliminary information on the product’s safety;
filing with the FDA of an IND, to conduct initial human clinical trials for drug candidates;
the successful completion of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate; and
filing by the companyCompany and acceptance and approval by the FDA of an NDA for a product candidate to allow commercial distribution of the drug.drug, which is beyond the scope of our financial resources. We intend on licensing or selling the technology prior to filing an NDA.
 
We consider the active management and development of our clinical pipeline to be crucial to our long-term success. The actual probability of success for each product candidate and clinical program may be impacted by a variety of factors, including, among others, the quality of the candidate, the validity of the target and disease indication, early clinical data, investment in the program, competition, manufacturing capability and commercial viability. Due to these and other factors, it is difficult to give accurate guidance on the anticipated proportion of our research and development investments or the future cash inflows from these programs.

Critical Accounting Policies and Significant Judgments and Estimates
 
Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements as well as the reported revenues and expenses during the reporting periods. On an ongoingon-going basis, we evaluate our estimates and judgments related to our operating costs. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates under different assumptions or conditions.
 
Our critical accounting policies include:
 
Revenue recognition. Revenue from grants is based upon internal and subcontractor costs incurred that are specifically covered by the grant, including a facilities and administrative rate that provides funding for overhead expenses. NIH grants are recognized when MabVax Therapeutics Holdings, Inc. incurs internal expenses that are specifically related to each grant, in clinical trials at the clinical trial sites, by subcontractors who manage the clinical trials, and provided the grant has been approved for payment. U.S. grant awards are based upon internal research and development costs incurred that are specifically covered by the grant, and revenues are recognized when the CompanyMabVax Therapeutics incurs internal expenses that are related to the approved grant.
 
Any amounts received by the CompanyMabVax Therapeutics pursuant to the NIH grants prior to satisfying our revenue recognition criteria are recorded as deferred revenue.

-32-

Clinical trial expenses. We accrue clinical trial expenses based on work performed. In determining the amount to accrue, we rely on estimates of total costs incurred based on the enrollment of subjects, the completion of trials and other events defined in contracts. We follow this method because we believe reasonably dependable estimates of the costs applicable to various stages of a clinical trial can be made. However, the actual costs and timing of clinical trials are highly uncertain, subject to risks, and may change depending on a number of factors. Differences between the actual clinical trial costs and the estimated clinical trial costs that we have accrued in any prior period are recognized in the subsequent period in which the actual costs become known. Historically, these differences have not been material; however, material differences could occur in the future.
 
Stock-based compensation. Our stock-based compensation programs include grants of stock options and restricted stock to employees, non-employee directors and non-employee consultants. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee’semployee, non-employee director or non-employee consultant’s requisite service period (generally the vesting period of the equity grant).
 
We account for equity instruments, including stock options and restricted stock, issued to employees and non-employees in accordance with authoritative guidance for equity based payments. Stock options issued are accounted for at their estimated fair value determined using the Black ScholesBlack-Scholes-Merton option-pricing model.model and restricted stock is accounted for using the grant date fair value of our common stock granted. The fair value of options and restricted stock granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered.

Warrant liability.We calculate the value of our warrant liability on a quarterly basis, or when other events and circumstances occur, using as a first step the Black-Scholes-Merton valuation model, taking into consideration the warrant exercise price, the probability of certain exercise price re-pricing scenarios, the market price for the common stock on the date of measurement, the risk-free interest rate, the dividend yield, the volatility of a comparable period in which the warrant may be exercised, and the remaining life of the warrant, and then as a second step we test our valuation for reasonableness based on settlement offers we have received from the holder of the warrant. If the settlement offer is within a reasonable period of time from when we do our calculation, and is not materially different from the value we recorded using the Black-Scholes-Merton model, then we retain the value established with our model. If the settlement offer were to reflect a materially different amount near the date of our calculation, then we would record the settlement offer.
Income taxes. Significant judgment is required by management to determine our provision for income taxes, our deferred tax assets and liabilities, and the valuation allowance to record against our net deferred tax assets, which are based on complex and evolving tax regulations throughout the world. Our tax calculation is impacted by tax rates in the jurisdictions in which we are subject to tax and the relative amount of income earned in each jurisdiction. Our deferred tax assets and liabilities are determined using the enacted tax rates expected to be in effect for the years in which those tax assets are expected to be realized.
 
The effect of an uncertain income tax position is recognized as the largest amount that is “more-likely-than-not” to be sustained under audit by the taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.
 
The realization of our deferred tax assets is dependent upon our ability to generate sufficient future taxable income. We establish a valuation allowance when it is more-likely-than-not that the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available evidence, both positive and negative. As of September 30, 2015, weDecember 31, 2016, MabVax Therapeutics concluded that it was more-likely-than-not that theits deferred tax assets would not be realized.realized, and a full valuation allowance has been recorded.

The above listing is not intended to be a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by GAAP.  See our audited consolidated financial statements and notes thereto included in our 2014 Annual Report on Form 10-K, as amended, which contain additional accounting policies and other disclosures required by GAAP.

LIQUIDITY AND CAPITAL RESOURCES
 
As of September 30, 2015,Liquidity and Capital Resources
From inception to December 31, 2016, we have financed our operations principally through net proceeds received from private equity and preferred stock financings, debt financings, and grants through the NIH and SBIR programs. We have experienced negative cash flowflows from operations each year since our inception. As of September 30, 2015,December 31, 2016, we had an accumulated deficit of $56,619,570.$78,262,261. We expect to continue to incur increased expenses, resulting in losses, over at least the next several years due to, among other factors, our continuing and planned clinical trials and anticipated research and development activities. We had an available cash balance of $4,538,680 as of September 30, 2015.

Net cash used in operating activities was $7,917,332 for the nine-month period ended September 30, 2015, compared to $5,700,951 in the comparable period in 2014. The net cash used in both periods was primarily attributableDue to the netsignificant research and development expenditures and the lack of any approved products to generate revenue, we have not been profitable and have generated operating losses adjustedsince we incorporated in 1988. As such, we have funded our research and development operations through government grants and contracts, sales of equity, debt, collaborative arrangements with corporate partners, and interest earned on investments. At December 31, 2016, we had available cash and cash equivalents of $3,979,290. Our cash and cash equivalents balances are held primarily in checking accounts.

We believe our cash and cash equivalents as of December 31, 2016 will be sufficient to fund our projected operating requirements through approximately April 2017. In order to continue our current and future operations and continue our clinical product development programs through 2017, we will depend on our ability to obtain additional funding in a timely manner or if at all. We are uncertain about our ability to raise sufficient funds to continue our existing operations after April 2017. We continue to explore alternatives that could include partnerships involving one or more of our product candidates, licensing arrangements with one or more of our product development candidates, merger with or acquisition by another company, or some other arrangement through which the value of our assets to stockholders could be enhanced. We may raise funds through arrangements with collaborators or others that may require us to relinquish rights to certain product candidates that we might otherwise seek to develop or commercialize independently. Our failure to raise capital when needed could materially harm our business, financial condition and results of operations. See Risk Factors.
Our future capital uses and requirements depend on numerous factors, including the following:
the progress and success of preclinical studies and clinical trials of our product candidates;
the progress and number of research programs in development;
the costs associated with conducting Phase I and II clinical trials;
the costs and timing of obtaining regulatory approvals;
our ability to establish, and the scope of, any new collaborations;
our ability to meet the milestones identified in our collaborative agreements that trigger payments;
the costs and timing of obtaining, enforcing and defending our patent and intellectual property rights; and
competing technological and market developments.
Future Contractual Obligations
 
MabVax Therapeutics has rental payment obligations under an operating lease that expired on July 31, 2015 related to its current facility at 11588 Sorrento Valley Road.  During the quarter ended September 30, 2015 the Company continued to occupy the current premises and continued the lease on a month-to month basis.

On September 2, 2015, the Company entered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises consisting of a total of approximately 14,971 square feet of office and laboratory space in buildings located at 11535-11585 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”). Due to the fact that certain tenant improvements needneeded to be made to the New Premises before the Company cancould occupy the New Premises, the term of the Lease will commence when the New Premises are ready for occupancy, currently estimated to be approximatelycommenced on February 8, 2016.5, 2015. The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the current monthly base rent will bepaid by the Company is $35,631, subject to annual increases as set forth in the Lease.

The Company has an option to extend the Lease term for a single, five-year period. If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value. In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued in connection with the ownership and operation of the property.

Our master lease and sublease of our facility located at 3165 Porter Drive in Palo Alto, California (the “Porter Drive Facility”) were terminated on February 28, 2013 and we entered into a termination agreement with AREARE-San Francisco No. 24 (“ARE”) on February 19, 2013 to voluntarily surrender its premises. As a result of the termination agreement, we were relieved of further obligations under the master lease and further rights to rental income under the sublease and paid a termination fee of approximately $700,000. In addition to the termination fee, if we receive $15 million or more in additional financing in the aggregate, an additional termination fee of $590,504 will be due to ARE, but will otherwise be forgiven.ARE. The additional financing was achieved in 2015 and the termination fee is reflected on the balance sheet as an accrued lease contingency fee.
 
We anticipate that we will continue to incur substantial net losses into the foreseeable future as we continue:we: (i) to manufacturecontinue our lead antibody candidate 5B1 in sufficient quantities for use in a Phase I clinical trial planned to befor our stand-alone therapeutic HuMab 5b-1, or MVT-5873, which was initiated in the fourthfirst quarter 2015,of 2016, (ii) initiate our Phase I clinical trial of our PET imaging agent 89Zr-HuMab-5B1, or MVT-2163, (iii) continue to conduct preclinical development activities related to other product development candidates in our library, and (iii) to(iv) monitor patients in clinical trials that have already completed their treatment regimens. We have obtained grant funding of $1.5 million to substantially offset the spending for our newest program to develop a diagnostic tool to detect pancreatic and colon cancers. Based on management’s assumptions for continuing to develop its existing pipeline of products without additional funding, we expect we will have sufficient funds to meet our obligations through June 2016.April 2017.
 
We plan to continue to fund our research and development and operating activities through public or private equity orfinancings, debt financings, strategic collaborations,partnerships or other arrangements with organizations that have capabilities and/or products that are complementary to our own capabilities and/or products, licensing arrangements, government grants, or other arrangements. However, we cannot be sure that such additional funds will be available on reasonable terms, or at all. If we are unable to secure adequate additional funding, we may be forced to reduce spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if we do not meet our payment obligations to third parties as they come due, we may be subject to litigation claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to our management. Any of these actions could materially harm our business, results of operations, and future prospects.
 
If we raise additional funds by issuing equity securities, substantial dilution to our existing stockholders would result. If we raise additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict our ability to operate our business.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,” and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB affirmed its proposal to defer the effective date of this standard to annual reporting periods (and interim reporting periods within those years) beginning after December 15, 2017. Entities are permitted to apply the new revenue standard early, but not before the original effective date of annual periods beginning after December 15, 2016. Entities may choose from two adoption methods, with certain practical expedients. We are currently reviewing this standard to assess the impact on our future financial statements and evaluating the available adoption methods.

In June 2014, the FASB issued ASU No. 2014-12, “Compensation–Stock Compensation” (Topic 718): “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. ASU No. 2014-12 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, although early adoption is permitted. We are currently reviewing this standard to assess the impact on our future financial statements.

In August 2014, the FASB issued ASU No. 2014-15, (“ASU 2014-15”), “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. Management is currently evaluating the impact of the adoption of the updated standard on the financial statements and disclosures.

Overview
 
We are a clinical-stage biopharmaceuticalbiotechnology company focused on discoveringthe development of antibody-based products to address unmet medical needs in the treatment of cancer.  MabVax has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been vaccinated against targeted cancers with our proprietary vaccines.  MabVax's lead development program is centered around our HuMab-5B1 antibody, which is fully human and developing innovative monoclonal antibody-based therapeutics (produceddiscovered from the immune response of cancer patients vaccinated with an antigen-specific vaccine during a Phase I trial at Memorial Sloan Kettering Cancer Center, or MSK.   The antigen the antibody targets is expressed on more than 90% of pancreatic cancers, and also expressed in significant percentages on small cell lung cancer, stomach, colon and other cancers, making the antibody potentially broadly applicable to many types of cancers.  We have other antibody candidates that are also in preclinical development.
Monoclonal antibodies are produced from a single DNA sequence encoded into multiple cells that all produce the same single antibody) for the diagnosis and treatment of cancer.antibody. We generate our pipeline of antibody-based product candidates from patients who have been vaccinated with proprietarypropriety vaccines licensed from MSK. Our approach ofinvolves surveying the protective immune response from many patients to identify the ideala monoclonal antibody candidate against a specific target on the surface of a cancer cell iscell. We believe this approach provides us with a novel next-generation human antibody technology platform. We believe our approach to antibody discovery identifies theallows us to identify antibody candidates with superior performance characteristics while minimizing many of the toxicity and off target binding drawbacks (phenomenon occurring when antibodies bind to non-cancer cells) of other discovery technologies. Our lead antibody candidates have been recovered from patients who have been reported to have had substantially better treatment outcomes than other patients in the clinical trials conducted by us and our partners.technologies.
 
Our therapeutic vaccines were developed at MSKGrowth and are exclusively licensedCore Business Strategy
Our primary business strategy is to us pursuant to agreements entered into in 2008. These vaccines are administered in the adjuvant (period following conventional treatment consisting of watchful waiting) setting and have shown in clinical studies to elicit a protectivedevelop our early antibody response. The antibodies are intended to seek out circulating tumor cells and micrometastases (small clusters of cancer cells) to kill them before they can cause cancer recurrence. Our lead cancer vaccines targeting recurrent sarcoma (soft tissue cancer) and ovarian cancer are currently inproduct candidates through proof of concept Phaseclinical trials, which may represent either phase I or phase II multi-center clinical trials. Both trials have received substantial federal grant moniesdepending on the program and extent of progress. We intend to support their development.then partner those product candidates having the highest clinical and commercial potential from our discovery library of antibody candidates.

AntibodiesRecent Developments
In November 2016, we reported on interim results of our two HuMab-5B1 antibody phase I clinical development programs evaluating the use of our therapeutic antibody we designate as targeted therapeutic treatmentsMVT-5873, and our immuno-PET imaging agent we designate as MVT-2163, comprised of MVT-5873 conjugated to a radio label. In December 2016, we submitted an investigational new drug application, or IND, to the U.S. Food and Drug Administration, or FDA, for our radioimmunotherapy product candidate we designate as MVT-1075, comprised of MVT-5873 conjugated to a low-energy radiation emitter and received authorization to proceed on January 27, 2017. These three product candidates are intended for use in patients with locally advanced and metastatic pancreatic cancer or other malignancies expressing the same cancer antigen known as CA19.9.
MVT-5873 Clinical Development Program Progress in Treating Pancreatic Cancer, and Near-term Plan
In our progress report released in November 2016, we stated that the safety of MVT-5873 had been established at three incremental dose levels by treating 16 patients at three clinical sites. The purpose of this phase I clinical trial, initiated in February 2016, is to establish safety and tolerability, and to determine the recommended phase II dose. Patients entering this part of the trial have becomeprogressive locally advanced or metastatic disease and have failed all previous treatments.
As of mid-November 2016, we reported that 28 subjects had consented to treatment, of which 16 subjects had been treated. Of the remaining subjects, nine had failed the screening tests, and three were still in the screening process. Of the 16 patients that had been treated as of that date, six were continuing to receive treatment beyond the study design of a significant market accounting28-day treatment cycle. Patients are able to remain on therapy beyond the initial 28-day treatment and safety assessment cycle based on acceptable dose tolerability and investigator assessment of continued benefit from the treatment. Every second treatment cycle the investigator assesses disease status using RECIST 1.1 measurement criteria to evaluate tumor response rate and duration of response. Investigators report that seven of the 16 patient patients converted from progressive disease to stable disease lasting from three months to eight months. We plan to continue to recruit patients in Part 1 of the study of MVT-5873, which is intended to establish the recommended phase II dose as a monotherapy.
In early February 2017, we reported that out of the total of 22 patients treated to date, eight had stable disease after at least two treatment cycles, or two months, seven continued to have stable disease after at least four treatment cycles, or four months; and three continued to have stable disease after at least six treatment cycles, or six months.
As a consequence of establishing the current dosage safety level for MVT-5873 in Part 1 of the trial, we have established a sufficient dosage safety margin to initiate part 2 of our phase I study. Part 2 combines our MVT-5873 with a standard of care chemotherapy regimen in new diagnosed treatment naïve patients. The dosage levels established in our MVT-5873 monotherapy trial have cleared all subsequent dose levels utilized in our Phase I clinical study of MVT-2163 as an immuno-PET imaging agent as well as the dose levels planned for our clinical study of MVT-1075 that combines the antibody with a radioactive metal as a radioimmunotherapy product. We filed an IND with the FDA in late December 2016 and received an authorization from the FDA on January 27, 2017 to proceed with our phase I clinical trial in the first half of 2017.
MVT-2163 Clinical Development Program Progress in Imaging Pancreatic Cancer, and Near-term Plan
In our progress report released in November 2016, we stated that we had established interim safety, and acceptable pharmacokinetics and biodistribution of MVT-2163 in our phase I clinical trial. We have completed the initial two cohorts of patients as specified in our protocol. In the first cohort we administered MVT-2163 alone and in the second cohort we administered MVT-2163 following a blocking dose of MVT-5873. We reported that the initial PET images demonstrated target specificity by correlation with lesions identified by conventional computerized tomography (CT) scans. The biodistribution data obtained in the first two cohorts demonstrated improvement in PET images by pre-administration of MVT-5873, as has been observed with other antibody based PET agents. We initiated the MVT-2163 phase I trial in June 2016 to evaluate a next generation diagnostic PET imaging agent in patients with locally advanced or metastatic adenocarcinoma of the pancreas (PDAC) or other CA19-9 positive malignancies. MVT-2163 (89Zr-HuMab-5B1) combines the well-established PET imaging radiolabel Zirconium [89Zr] with the targeting specificity of MVT-5873. We designed the trial to establish safety, pharmacokinetics, biodistribution, optimal time to obtain the PET image, and the amount of MVT-5873 to be used in co-administration to obtain optimized PET scan images. We continue to actively recruit patients and expect to establish the optimal co-administration dose of MVT-5873 early in 2017.
MVT-1075 Clinical Development Plan
We are developing HuMab-5B1 into a third potential product for use as a radioimmunotherapy that we have designated as MVT-1075. MVT-1075 represents a unique product opportunity for MabVax by conjugating MVT-5873 with a low-energy radiation emitter, 177Lu, which has a relatively short tissue penetration range to minimize potential side effects of the radiation. MVT-5873 provides the opportunity for tumor-specific targeting of a more potent analog of MVT-5873. We submitted our IND in late December 2016, and the IND was authorized to proceed on January 27, 2017. We plan to initiate the phase I trial of MVT-1075 in the first half of 2017.

Antibody Market Opportunity
The global monoclonal antibodies market was valued at $85 billion in revenue. Eight2015 and is expected to reach a value of $138 billion by 2024 (The Pharma Letter, February 11, 2016). Over the leading twenty therapeutic products forpast couple of decades, the treatment of cancer are antibodies. There areUS FDA has approved more than 150a dozen monoclonal antibodies in development for cancer alone (the foregoing data is according to Global Data’s commercial database Pharma eTrack)treat certain cancers (cancer.org). The focus on theFocused development of new monoclonal antibody based drugs is expected to continue for multiple reasons.  Over the last few years much has been learned about using the human immune system to treat cancer.  Several recently approved antibody therapies have demonstrated remarkable efficacy in marshalingstimulating the human immune system to treatattack certain cancers. Targeted therapies can attack cancer cells while minimizing damage to normal cells in the patient. Antibodies are complex molecules and are difficult and expensive to duplicate with biosimilars and therefore have a potentially longer commercial life. Currently approved monoclonal antibodies receive veryare reimbursed at favorable reimbursement levels from federal, state, and private insurance providers. We believe that this favorable treatment is expected to continue.
 
We have focused our initial antibody development efforts on matching the early antibody discoveries against diseases for which there remains a significant unmet medical need. Our lead antibody candidate targets an antigen that is over expressed on many metastatic pancreatic, colon, breast, and small cell lung cancers. The term "over expressed" refers to the antigen being present on the surface of the cancer cell in very large numbers. The amount of antigen present in blood samples is used to monitor patients as elevated levels occur in the blood due to shedding into the blood from these cancer cells. Patients who develop metastatic disease with these cancers have a significantly poorer prognosis. In the case ofprognosis for survival.
We believe there is a critical unmet medical need for new and better treatment for metastatic pancreatic and small cell lungcolon cancer. According to NCI’s SEER database (seer.cancer.gov), the five-year survival rate for patients with pancreatic cancer weis just 7.7%. There are 53,000 new patients with pancreatic cancer diagnosed per year and more than half of these patients present at initial diagnosis with metastatic disease (Pancreatic Cancer Network’s Pancreatic Facts 2016). In 2016 pancreatic cancer moved from the fourth leading cause of cancer related death in the U.S. to third, surpassing breast cancer (American Cancer Society Cancer statistics 2016 report,). According to the SEER database, there are about 134,000 patients diagnosed with cancer of the colon and rectum per year in the US. The five-year survival rate for the 35% of patients with metastatic colon cancer that is locally spread is 71% and the five-year survival of the 35% of patients that have regional spread is only 13.5%.
Pancreatic Cancer Imaging and Diagnosis
We believe that there are no treatments currently available thatour radiolabeled HuMab-5B1 PET imaging antibody represents the only human derived agent in development specifically focusaimed at improving imaging in pancreatic cancer diagnosis over the standard of care (FDG-PET). Since the antigen targeted by the HuMab-5B1 antibody is over expressed on metastatic disease.pancreatic cancer cells, this development effort represents a potentially important step forward in the diagnosis, staging, and assessment of the majority of patients newly diagnosed with pancreatic cancers. We believe that the market opportunity for a HuMab-5B1antibody-based radiopharmaceutical is significant in multiple ways. The ability of physicians to accurately diagnose, stage, and assess treatment outcomes in pancreatic cancer would be very important. Accurate determinations on the extent of disease and resectability are essential to improve outcomes in this cancer. We believe that limitations in FDG-PET imaging offers significant room for improvement in diagnostic technique and that accurate determinations on extent of disease and resectability are essential to improving outcomes in this cancer. Improvements in the sensitivity and specificity over FDG-PET could have a significant impact on improving diagnosis and clinical outcome.
Radioimmunotherapy: Therapeutic Treatment Product
In addition to developing this lead antibodyour HuMab-5B1 as a stand-alone therapeutic agent as well as combining it with a radiolabel for use as a novel PET imaging agent. According to the National Cancer Institute’s SEER database, thereagent, we are approximately 100,000 patients annually who develop metastatic disease from these cancers who could potentially benefit from this antibody if it is successfully developed. Both of these products have completed preclinical development and GMP manufacturing of Phase I clinical material. Phase I clinical trials are scheduled to start in the first quarter 2016.
Phase I Clinical Trial of HuMab 5B1 – In December 2015, we received notice from the U.S. Food and Drug Administration (FDA) authorizing the initiation a Phase I clinical trial with HuMab 5B1 as a therapeutic treatment for pancreatic cancer.  We filed an Investigational New Drug (IND) application for our lead fully human antibody product on November 30, 2015.  Patient enrollment in the Phase I clinical trial is expected to begin at multiple investigational sites in the first quarter of 2016.  The Phase I trial will evaluate the safety, tolerability and pharmacokinetics of HuMab 5B1 as a single agent or in combination with a standard of care chemotherapy regimen in subjects with metastatic pancreatic cancer.  The first cohort of patients will be enrolled in a traditional dose escalation regimen to assess safety and determine the optimal dose of the antibody.  A second patient cohort will establish the safety and optimized dose of the antibody when administered with a standard of care chemotherapy.   Two additional patient cohorts will be administered the optimized dose of antibody as a single agent, or in combination with a standard of care chemotherapy regimen, for the treatment of patients with pancreatic cancer.

Phase I Clinical Trial of 89Zr-HuMab-5B1 – In January 2016, we filed an IND application with the FDA for 89Zr-HuMab-5B1, utilizing our fully human antibody product as a new generation PET scan cancer imaging agent.  Subject to FDA authorization to proceed, we plan to initiate the Phase I clinical trial in patients with pancreatic cancer in early 2016.  The 89Zr-HuMab-5B1 imaging agent has demonstrated high-resolution images of tumors in xenograft animal models, potentially making it an important new tool to aid in the diagnosis, monitoring and assessment of pancreatic cancer patients and an attractive companion diagnostic for the HuMab-5B1 therapeutic product. This second planned Phase I trial will evaluate the safety, pharmacokinetics and biodistribution of 89Zr-HuMab-5B1 in cancer patients.  The trial will also determine the ideal dose and conditions for an optimal PET scan image using the new imaging agent.

Follow-on HuMab-5B1 Programs – We have initiated development ofdeveloping a HuMab-5B1 based radioimmunotherapy, or RIT, product candidate as a potential treatment for the treatment of pancreatic cancer.  Using what we have learned from our 89Zr-HuMab-5B1 imaging programcancer and working with the Radiology and Nuclear Medicine Departments of MSK, weother CA19-9 positive tumors. Our preclinical animal studies have demonstrated the potential feasibility and experimental proof of concept for this new product.product candidate. We anticipate completinghave learned from our 89Zr-HuMab-5B1 PET imaging clinical development program that we have sufficient safety and specificity of the preclinical work onproduct to proceed with clinical development of our RIT program. We submitted an IND to FDA for this product in mid-2016December of 2016 and file a third IND for a HuMab-5B1 based product beforereceived FDA authorization in January 2017 to proceed with our proposed clinical trial.   We anticipate initiating our clinical trial in the endfirst half of 2016.2017.

On September 24, 2015, we entered into a licensing agreement with Life Technologies Corporation, a subsidiary of ThermoFisher Scientific (“Life Technologies”).  Under the agreement we agreed to license certain cell lines from Life Technologies to be used in the production of recombinant proteins for our clinical trials.  The amount of the contract is for $450,000 and was fully expensed during 2015.  We paid $225,000 during 2015 related to this contract with the remaining amount paid in 2016.
Rockefeller University Collaboration
In July 2015, we entered into a research collaboration agreement with Heidelberg Pharma GmbH for the development and evaluation of a HuMab-5B1 based antibody drug conjugate (ADC) product.  We think that a much more potent follow-on product to our basic antibody therapeutic product will be a key addition to the HuMab-5B1 product portfolio as well as for treatment of difficult cancers.  We have supplied Heidelberg Pharma GmbH with HuMab-5B1 antibody and they have created ADC constructs using their linker and toxin technology.  These constructs are being tested in both in vitro and animal models of disease.  Early results from both sets of experiments have been strongly encouraging and we are continuing this development effort.

Preclinical Development of Other Antibodies – We have initiated development efforts on a second antibody that targets an antigen over expressed on the surface of sarcoma, melanoma, and neuroblastoma. The use of a targeted antibody therapy in neuroblastoma in a study sponsored by NCI and published in the New England Journal of Medicine has demonstrated that antibodies targeting this antigen can be effective. We are focused on developing an antibody-based drug for the treatment of sarcoma. While there are newer agents being developed to treat sarcoma, it is a difficult to treat cancer with unacceptably high recurrence rates. We believe that there are approximately 30,000 patients who could potentially benefit from this antibody if it is successfully developed. This product is in preclinical development
Vaccine Programs –Full enrollment was achieved in both the sarcoma and ovarian cancer vaccine Phase II clinical trials. Both clinical programs are following patients to the overall survival, or OS, endpoint that we expect could be reached in late 2016 or 2017. Our discussions with the FDA at the time we developed the protocols for our vaccine trials indicated that the OS endpoint was the primary criteria for their evaluation of the efficacy and safety of the vaccines.
Product Candidates
5B1 Antibody Program

Of the many tumor restricted monoclonal antibodies resulting from immunization of mice with human cancer cells, the majority of antibodies have been directed against carbohydrate antigens (structures consistently expressed and are targets for therapeutic intervention) expressed at the cell surface. The carbohydrate antigen sialyl Lewisa (sLea) is the antigen recognized by monoclonal antibody CA19.9 and it is widely expressed on tumors of the gastrointestinal tract. These tumor types are generally classified as epithelial tumors (a broad classification of tumor types) and include pancreatic, colon, stomach, ovarian, breast, and small cell lung cancers. A CA19.9 serum test is the only FDA validated marker for pancreatic cancer and is a commercial test that is readily available and used frequently to aid in the diagnosis of pancreatic cancer. Circulating epithelial cancer cells over-express sLea (abbreviation for the antigen sialyl Lewis A) and as a ligand (binding partner) for E selectin (a structure in the inner lining of blood vessels) this antigen facilitates tumor—tissue interactions that are key events for tumor metastasis. Patient outcomes appear to be worse in patients with metastatic tumors expressing higher levels of sLea according to articles published by T. Ben-David and colleagues in Immunology Letters in 2008 and YI Kawamura in Cancer Research in 2005. Because these tumor types express very high numbers of the sLea antigen on their cell surface, it makes the antigen an attractive target for therapeutic intervention.
We have created a series of fully human monoclonal antibodies against sLea. One antibody in particular, 5B1, has demonstrated exceptionally high affinity and specificity for sLea, and has very good efficacy in multiple tumor xenograft models (human cancer cells engrafted into mice) in studies conducted by MSK.  5B1 is a fully human full-length monoclonal antibody we discovered by capturing a portion of the immune response from seven stage IV breast cancer patients who were being vaccinated in a Phase I trial in 2008 at MSK with one of our licensed vaccines.
We have conducted tissue microarray work (normal and cancer tissue samples placed on slides treated with the antibody to determine if an antibody binds to such tissue samples) with commercially available tissue samples of both normal and cancer tissues. The results of this work indicated that the 5B1 antibody bound to multiple types of epithelial tumors, including pancreatic, colon, bladder, ovarian, breast, and small cell lung cancer tissues. The antibody did not bind to normal tissues except for the exocrine cells at the ductal border of secretory cells (primarily cells in the gastrointestinal tract that face into the digestive system and not inward to the body) in epithelial tissues; those sites are less accessible to the immune system. Both characteristics combined with the significant cytotoxicity demonstrated in in vitro testing led us to move to xenographic animal model testing. 5B1 has demonstrated in our pre-clinical studies good anti-tumor activity in a variety of animal models with multiple tumor types. Specifically, we have obtained positive results from animal models examining human pancreatic, colon, and small cell lung cancers.
We entered into a manufacturing agreement with Patheon Biologics LLC (f.k.a. Gallus BioPharmaceuticals) to manufacture clinical supplies of the antibody which were completed in early 2016.  We submitted an IND for the therapeutic product in November of 2015 and on December 24t, 2015, we received FDA authorization to initiate the Phase I study.  We plan to start patient enrollments in the first quarter of 2016 to determine the safety and pharmacokinetics (assessment of the distribution and metabolism of a drug) of the 5B1antibody in patients with pancreatic cancer. We expect the preliminary results of our Phase I studies to be available in the third quarter 2016 with full Phase I results at the end of 2016 or early 2017.
5B1 Imaging Program
Circulating biomarkers (substances released by certain cells that can be measured to assess if a patient has or is likely to have a particular type of cancer) such as CA19.9 are important clinical tools for early detection and diagnosis as well as monitoring of therapeutic progress, and detection of tumor recurrence in oncology. However, false positive readings due to biomarker production from benign disorders in unrelated host tissues are a significant problem. We believe that probing the site(s) of biomarker secretion with an imaging tool could be a broadly useful strategy to enhance the fidelity of diagnosis and staging of cancers such as pancreatic ductal adenocarcinoma, or PDAC, a notoriously occult (difficult to diagnose and treat) cancer. Moreover, such a tool could guide patient stratification for directed therapeutic intervention, surgical planning and aide in the evaluation of tumor response to chemotherapy and radiation therapy. To address this opportunity clinically, together with Dr. Jason Lewis’ radiochemistry laboratory at MSK, we developed 89Zr-5B1, a fully human, antibody-based radiotracer (combined antibody and radiolabel) targeting tumor-associated CA19.9. In preclinical studies,89Zr-5B1 localized to tumors in multiple models representing diseases with both undetectable and clinical relevant circulating CA19.9 serum levels. Among these, 89Zr-5B1 detected tumor in an orthotopic model (xenograph model where human cancer cells are surgically implanted in the corresponding organ of the mouse) of PDAC, an elusive cancer for which the serum assay (actual test for a biomarker) is measured in a human, but with limited specificity in part because of the frequency of CA19.9 secretion from benign hepatic pathologies (certain non-cancer conditions such as inflammation causing the production of the target biomarkers resulting in a false reading). Of further note, in preliminary experiments 89Zr-5B1 showed better tumor specificity (targeting only a specific type of cancer cell) compared to the commonly used 2-deoxy-2-(18F)-fluoro-D-glucose, or FDG, imaging agent, which relies on increased tumor metabolism relative to nonmalignant cells, and is known to lack sensitivity and specificity in pancreas cancers and other slow growing cancers.
To facilitate the development of the 5B1based antibody conjugated to a radiolabel as a novel PET imaging agent for pancreatic cancer, we applied for and received a development contract from NIH pursuant to which NIH may provide up to $1.75 million in non-dilutive funding for this project. Pending FDA authorization of our IND to proceed, we intend on beginning patient enrollments in a Phase I study in the first quarter 2016, and expect to have preliminary results by the third quarter 2016, with full Phase I results in 2017.
5B1 Antibody Drug Conjugate
We observed in our clinical studies that certain types of cancer cells internalized the 5B1 antibody. These were primarily pancreatic cancer tumor types. We believe that this characteristic of the 5B1 antibody could be highly useful in constructing an antibody-drug conjugate. The development of antibody-drug conjugates is an area of intense competitive development with few companies capable of producing viable linker and toxin technologies that can be coupled with an antibody which, in this case, serves as the targeting mechanism. According to an analysis conducted utilizing the online database Global Data, over the last few years more than 21 technology access licensing deals worth more than $6 billion have been completed by biopharmaceutical companies to gain access to these technologies.
Other Research Collaborations
We were able to identify and form collaborations with various partners, including Heidelberg Pharma GmbH who has developed its own proprietary linker and toxin technology. For the collaboration, we were able to supply the 5B1 antibody and Heidelberg has conducted both in vitro and in vivo experiments demonstrating the significant potential utility of this combination. We are hoping to expand this collaboration and continue a joint development program to bring this new product to the clinic.

Antibody Discovery
-38-
 
We have discovered and recombinantly expressed multiple fully human antibodies to eleven separate antigenic targets over expressed on multiple types of cancer. The antigenic targets are incorporated in various combinations making up the eight vaccines that were licensed from MSK and have been in at least Phase I clinical trials. To date, six separate vaccines have entered early stage clinical programs and we have received antibody discovery material from all patients who participated in five of the trials. Exclusive access to these patient samples is covered under separate licenses with MSK. We have discovered multiple antibodies to important cancer targets such as MUC1, GD3, GM2, Fucosyl-GM1, Globo-H, Tn, sTn, and TF. As we continue to raise additional capital and add capacity, it is our intention to begin moving these early product development candidates forward toward clinical evaluation.

Current Approach to Treatment of Pancreatic Cancer
According to an articleour binding domains for use in the Journalconstruction of Advanced Practitioner in Oncology, or Advanced Practitioner, by Sheena Daniels, DNP, ARNP, FNP-BC and colleagues in 2011, for the more than 80% of patients diagnosed with pancreatic cancer who will not be candidates for resection and a large number (80%) of patients who were able to have resection but will develop metastases within 2 to 3 years, the drug gemcitabine has been established as the standard of care because of its documented advantage in OS and more favorable side-effect profile. In patients who are not resectable (able to remove through surgery), combination therapy with a gemcitabine-based systemic regimen followed by consolidation with chemoradiation has produced some favorable median survival durations.CAR T-cells.
Newer Therapeutic Agents
According to Daniels’ article in the Advanced Practitioner, in spite of aggressive treatment, patients with unresectable pancreatic cancer have a median survival of 10 to 14 months and an estimated 1 in 4 patients who undergo pancreatic resection do not recover sufficiently from surgery to allow administration of systemic chemotherapy. Newer targeted agents have been studied in combination with gemcitabine but did not correlate with improved OS. However, according to Daniel, the combination of gemcitabine and erlotinib did improve overall survival from 5.91 months to 6.24 months and 1-year survival improved to 23% vs 17%. These results were not duplicated using multi-targeted kinase inhibitors. There are several ongoing trials combining additional chemotherapeutic agents with gemcitabine and early results show improvements in PFS and OS but come at a significant cost of increased adverse events. Nab-paclitaxel combined with gemcitabine has produced positive results in an early Phase II trial and those results were confirmed in a subsequent Phase III trial. Nab-paclitaxel is now approved for treatment of pancreatic cancer and the combination of gemcitabine and Nab-paclitaxel is considered first line therapy in many institutions.
We believe there is a significant unmet medical need for newer agents that can treat metastatic disease. Pancreatic cancer is an area of intense research with much of the late stage clinical development efforts targeted toward advanced and metastatic disease. According to the online database BCIQ from BioCentury, to date there are 92 products in all three stages of clinical development from a total of 86 companies and there are 14 products in Phase III or pivotal trials at this time.
Potential Market Opportunity for the Full Length Therapeutic Antibody 5B1
We believe there is a critical unmet medical need for new and better treatment for metastatic pancreatic and colon cancer. According to the National Cancer Institute’s SEER database, the five-year survival rate for patients with metastatic pancreatic cancer is just 1.8%. There are 43,000 new pancreatic cancer patients per year and more than half of them present at initial diagnosis with metastatic disease. According to the SEER database, the five-year survival rate for patients with metastatic colon cancer is only slightly better at 12%. According to the SEER database, while most of the 141,000 new patients can be treated successfully initially, almost half of all colon cancer patients will develop metastatic disease. Thus, adding the number of metastatic disease patients for these two cancers alone represent 96,000 new metastatic cancer patients per year. Using the cost of current antibody therapies as a baseline, the market potential for an annual patient population of 96,000 is in excess of $1 billion per year.
Pancreatic Cancer Imaging and Diagnosis
We believe that the radiolabeled HuMab-5B1 antibody represents the only human derived agent in development specifically aimed at improving imaging in pancreatic cancer. Since the antigen targeted by the HuMab-5B1 antibody is significantly and preferentially over expressed on metastatic pancreatic cancer, this development effort represents a potentially important step forward in the diagnosis, staging, and assessment of the majority of pancreatic cancer patients. We believe that the market opportunity for a 5B1antibody-based radiopharmaceutical is significant in multiple ways. The ability of physicians to accurately diagnose, stage, and assess treatment outcomes in pancreatic cancer would be very important. Accurate determinations on the extent of disease and resectability are essential to improve outcomes in this cancer. We believe almost all patients diagnosed with pancreatic cancer could potentially benefit from 89Zr-HuMab-5B1 scan. Accordingly, improvements in the sensitivity and specificity of one of the primary diagnostic tools could have a significant impact on clinical outcome.
Currently, according to Daniels’ article in the Advanced Practitioner, all screening methods for pancreatic cancer have limitations. The symptoms associated with the disease are often vague and attributed to other more benign etiologies. Diagnosing pancreatic cancer is often challenging, as the presenting symptoms of pancreatic, hepatobiliary (portion of the liver, pancreas, and biliary tract), and upper gastrointestinal cancers are similar. Screening for pancreatic cancer, according to Daniel, is difficult primarily because there are no tumor markers that can be screened at an early stage of disease. Therefore, according to Daniel, the majority of pancreatic cancers are diagnosed at a late stage of disease hampering efforts to provide curative therapy. Pancreatic cancer is typically diagnosed by a combination of history and physical examination, coupled with CT, ultrasound, and PET imaging. In patients deemed to be at high risk for metastasis or for whom the staging is indeterminate, the diagnosis is confirmed by fine needle aspiration or laparoscopy along with FDG-PET. Accurate staging, particularly identification of distant metastases, is of paramount importance in order to properly select patients who are the most likely to benefit from surgery. Differential diagnosis between pancreatic cancer and pancreatitis (non-cancerous inflammation of the liver) is a common problem with imaging modalities.
Recent Developments in ImmunoPET Imaging
2-deoxy-2-(18F)-fluoro-D-glucose, or FDG, combined with PET imaging alone, or FDG-PET, combined with CT scanning, or FDG-PET/CT, is commonly used to augment the diagnosis and staging of pancreatic cancer. According to an article in The American Journal of Surgery by Lan and colleagues in 2012, FDG-PET is the principal imaging agent available today for enhanced PET imaging for pancreatic cancer. FDG is a radiolabeled form of glucose and because cancer cells normally have elevated metabolic rates, highly active cells will incorporate this glucose marker and as a result can potentially help pinpoint pancreatic cancer and potential metastases.
To date, there have been 17 studies examining the accuracy of FDG-PET and the conclusions are mixed. While studies are heterogeneous (not of a similar type; not uniform), the utility of FDG-PET was reasonably established for the primary diagnosis purposes only, utility of FDG-PET/CT for determining recurrence and staging was not confirmed. Additional studies have evaluated the diagnostic thinking impact of FDG-PET with regards to patient management and diagnostic work-up of pancreatic cancer. Findings from FDG-PET lead to changes in the pre-treatment staging as well as the decisions regarding treatment management because of changes in resectability status. The majority of findings demonstrated previously unsuspected metastases and resulted in cancellation of previously planned surgical resection. Roughly half the time the newly identified metastases had not been detected by initial CT scans.
The cost-effectiveness of adding FDG-PET to the routine diagnostic procedures to determining staging and eligibility for surgery among patients with presumed resectable pancreatic cancer has been examined in a limited number of studies. Cost savings were identified primarily by identifying patients who were initially staged for surgery and later deemed ineligible because of detected metastases.
Although FDG is used extensively and successfully in many cancers, because of the targeting characteristics of this compound as a marker of glucose metabolism, the sensitivity and specificity of FDG are not optimal in all cancer types. The shortfalls of imaging with FDG, such as inadequate differentiations between post-therapy inflammation and tumor, poor imaging in slow-growing tumors, and high uptake in normal cells such as brain and gut, have remained as the justification for the development of newer PET tracers.
FDG-PET Reimbursement
The Department of Health and Human Services has completed a Technology Assessment for FDG-PET in pancreatic cancer. The Centers for Medicare and Medicaid Services, or the Center, utilized the Technology Assessment and has issued a National Coverage Determination for FDG for oncologic conditions. The Center has elected to cover the expense of using FDG-PET for the diagnosis and staging of pancreatic cancer. However, the Technology Assessment found insufficient support for fully covering FDG-PET for restaging and monitoring response to treatment. Private insurance carriers follow the Center’s recommendation and cover FDG-PET for diagnosis and staging.
Potential Market Opportunity
To our knowledge, the radiolabeled HuMab-5B1 antibody represents one of the only agents in development specifically aimed at improving imaging in pancreatic cancer. Since the antigen targeted by the HuMab-5B1 antibody is significantly and preferentially over expressed on metastatic pancreatic cancer, this development effort represents a potentially important step forward in the diagnosis, staging, and assessment of the majority of pancreatic cancer patients. Using an imaging agent that is specific for a pancreatic cancer antigen would be greatly preferable to an indirect marker that can produce false positive results in high metabolic rate tissues (tissues where there is an elevated metabolism of sugar due to a variety of causes including cancer) or a false negative in slow growing cancers. We believe that the market opportunity for a HuMab-5B1 antibody-based radiopharmaceutical is significant in multiple ways. First the ability of physicians to accurately diagnose, stage, and assess treatment outcomes in pancreatic cancer would be very important. Accurate determinations on extent of disease and resectability are essential to improving outcomes in this cancer. We believe improvements in the sensitivity and specificity of one of the primary diagnostic tools would be useful and that potentially almost all patients diagnosed with pancreatic cancer could benefit from a 89Zr- HuMab-5B1 antibody scan. Using existing utilization and reimbursement rates for the current standard of care product, FDG-PET, annual revenues for a 5B1 antibody-based radiopharmaceutical could exceed $100 million per year. Since the regulatory pathway is significantly less expensive and time consuming than a therapeutic agent, we believe that this companion diagnostic product opportunity will complement the full-length therapeutic antibody and antibody-drug conjugate products.
This project is also important to us because of the potential enablement of the full-length therapeutic antibody. The 89Zr- HuMab-5B1 antibody will be essential in the clinical development of the HuMab-5B1 antibody. It would help improve our understanding of the antibody’s in vivo behavior including the interaction with its critical disease target, mechanism of action, distribution, and potential toxicities. Just as important, we believe the 5 HuMab-B1 antibody-based radiopharmaceutical would enable physicians to identify patients with the greatest chance of benefiting from treatment with the antibody and that the 5B1Db-based radiopharmaceutical would enable accurate diagnosis, staging, and assessment of treatment outcome of a new antibody treatment for advanced pancreatic cancer.
License Agreement with MSK
We have licensed from MSK the exclusive world-wide developmental and commercial rights to receive biological materials from vaccinated clinical trial participants enrolled in any of the clinical trials involving the vaccines licensed to us, allowing us to discover human monoclonal antibody-based therapeutics. MSK has issued patents or has pending patent applications on the vaccine antigen conjugates, mixtures of vaccine antigen conjugates and methods of use. This patent portfolio includes 25 issued patents in the US and rest of world along with 2 patent applications.  We own all monoclonal antibodies produced by the antibody discovery program and we generally file patent applications directed to these antibodies once their potential therapeutic utility has been sufficiently demonstrated in animal models. A United States and an international patent application for each of the anti-sLea antibodies and the anti GD2 antibodies described in this document has been filed.
We are unique in that only a very small number of oncology focused companies are vaccinating patients with carbohydrate-based vaccines intended to elicit an antibody response and, to the best of our knowledge, we are the only company deriving antibodies from the lymphocytes of vaccinated patients. Since these carbohydrates are very difficult to make immunogenic and the carbohydrates cannot be easily manufactured, it is very difficult if not impossible to find a source for human antibodies to these antigens beyond that utilized by us.
Vaccine Program
We have licensed exclusive rights from MSK to exploit key aspects of the work of Dr. Livingston (who is also a member of our board of directors) and colleagues, who over the last 30 years have developed a series of monovalent (targeting a single tumor cell surface antigen) cancer vaccines against cancers of neuroectodermal and epithelial (breast, ovarian colon, pancreatic) origin as well as small cell lung cancer ( SCLC). These target molecules on malignant cells, known as carbohydrate antigens, are the most extensively expressed antigenic targets on the cell surface of these types of cancers and play a key role in tumor progression and metastasis. We expect to benefit from the years of work and significant expense already invested in the development and testing of the vaccines incorporating these antigens. Researchers at MSK have progressively developed highly immunogenic monovalent vaccines to each of the 11 validated target antigens that comprise the licensed vaccines. These monovalent vaccines or the combination of the monovalent forms into polyvalent vaccines (targeting multiple antigens) have been tested and refined not only in animal models but also in multiple clinical trials establishing immunogenicity, tolerability, and therapeutic utility. Our license agreement with MSK calls for MSK to complete all preclinical and Phase I clinical trial work at MSK’s expense at which point the Investigational New Drug Application, or IND, would be transferred to us for continued development.
Our lead cancer vaccines targeting recurrent sarcoma and ovarian cancer are currently in proof of concept Phase II multi-center clinical trials. Both trials are fully enrolled, and have received substantial federal grant monies to support their development.
Our Vaccines Intend to Address Recurrent Cancer, An Unmet Medical Need
Despite undergoing potentially curative surgical resection or combination therapy, a significant number of patients with cancer will have their cancer recur. Patients with recurrent cancer have a significantly lower survival rate and incur much higher medical costs compared to those whose disease does not recur. Multiple clinical studies have demonstrated that additional courses of chemotherapy or radiation in the adjuvant setting do not or only minimally improve outcomes for these patient groups. Thus, in the majority of cases, the current standard of care following treatment of metastatic disease and the achievement of disease-free status is watchful waiting. Sarcoma references: Potter DA, et al: J Clin Ohcol 3:353-66, 1985, Rizzoni WE, et al: Arch Surg 121:1248-52, 1986, Casson AG, et al: Cancer 69:662-8, 1992. Ovarian references: Armstrong DK, etal N Engl. J Med 354:34-43, 2006, Markman M, et al: J Clin Ohcol 22:3120-3125, 2004. .Consequently, there is an unmet medical need for new treatments for recurrent disease.
Medical Solution and Rationale
According to an article in Human Vaccines by Livingston and colleagues published in 2006, the adjuvant setting is the ideal time for immune intervention and in particular for administration of monoclonal antibodies or cancer vaccines aimed at instructing the immune system to identify and kill the few remaining circulating cancer cells. We believe that passively administered or vaccine induced antibodies against selected cell surface antigens are ideally suited for eradication of free tumor cells and micrometastases. This is the role of antibodies against most infectious diseases, which has been accomplished against cancer cells in a variety of pre-clinical models and recent clinical trials. We also believe that if antibodies of sufficient titer can be administered or induced by vaccination against tumor antigens to eliminate tumor cells from the blood and lymphatic systems and to eradicate micrometastases, this could dramatically change the approach to treating the cancer patient. If successful, establishment of new metastasis would no longer be possible, so aggressive local therapies including surgery or radiation therapy, and intralesional (injection of cancer treatment directly into a tumor) treatments, combined with our immunotherapeutic agents could result in long term control of metastatic cancers.
Vaccine Purpose Determines Vaccine Design
According to Livingston’s article in Human Vaccines, the majority of carbohydrate antigens are recognized exclusively by B-lymphocytes and antibodies and the optimal approach for augmenting antibody responses against defined antigens involves conjugation of the antigens to a highly immunogenic carrier protein. This is the approach currently used in a variety of vaccines against bacterial pathogens and is the approach we believe to be optimal for cancer associated carbohydrate antigens (antigens/targets made of carbohydrates; also known as sugar structures) as well.
We have explored a variety of methods for augmenting the antibody response to defined antigens including vaccine production with autologous (derived from a subject’s own cells) or allogeneic (derived from another subject’s cells) tumor cell lines or lysates, the use of multiple different immunological adjuvants, chemical modification of antigens to render them more immunogenic, conjugation to different immunological carrier proteins and adherence of antigens to a variety of vehicles including liposomes (artificial structures that can carry active agents into the body), polystyrene beads (small synthetic beads), BCG and Salmonella. The conclusions from these studies are that the use of an immunogenic carrier protein plus a potent immunological adjuvant is the optimal approach. The studies established that the optimal carrier protein was KLH, while the optimal adjuvants were saponins (class of adjuvants) such as QS-21 or OPT-821obtained from the bark of Quillaia saponaria (type of tree indigenous to South America). Both conjugation to KLH and use of a saponin (substance derived from Quillaia saponaria) adjuvant are required for an optimal response. The role of the carrier protein in these conjugate vaccines was induction of a potent T-cell response against KLH, resulting in a cascade of cytokines (immune system cells essential to immune response) which then provide help for the antibody response against both KLH and more weakly immunogenic molecules attached to KLH. The primary role of the saponin adjuvants appeared to be augmentation of the immune response against KLH.
Previous Human Clinical Experience
There are an increasing number of clinical trials showing that passively administered monoclonal antibodies, or mAbs, against cell surface antigens such as HER2/neu, EGF receptor, VEGF, CD20, CD33 and CD52 have demonstrated clinical efficacy against human cancers and leukemias. Specifically, according to an article in Clinical Breast Cancer by Jahanzeb there is evidence from a series of recently described clinical trials with Trastuzumab (Herceptin®, against HER2/neu) used in breast cancer patients in the adjuvant setting confirming a striking recurrence free and overall survival advantage. This is a more dramatic response than seen with the same mAb used in the more advanced disease setting. Finally, naturally acquired or vaccine induced antibodies against cancer cell surface antigens such as GM2 and sTn have correlated with improved prognosis in several different clinical settings. Murine (mouse origin) monoclonal antibodies 3F8 against GD2 and R24 against GD3 have each induced clinical responses in a significant proportion of melanoma patients in the advanced disease setting. 3F8 and R24 are murine monoclonal antibodies and so can only be administered briefly before human anti-mouse antibodies, or HAMA, induction leads to decreased clinical availability.
There has been a significant amount of clinical work in the development of the monovalent and polyvalent versions of these cancer vaccines that stretches over two decades. In the Investigator’s Brochure portion of the INDs submitted to FDA on behalf of the sarcoma and ovarian cancer vaccine trials, we list the 30 Phase I clinical trials testing immunogenicity and tolerability of each of the monovalent vaccines to date. Refinements in antigen configuration, selection of carrier molecules, selection of adjuvant, vaccination schedules, and dose ranging have all lead to the optimal configuration of the current vaccines. According to Livingston’s article in Human Vaccines, the current monovalent vaccines all induce an immune response of IgM and IgG antibodies capable of killing targeted cancer cells.
Concern for Autoimmune Disease
Antigens on cancer cells are generally either autoantigens or slightly modified autoantigens (antigens or targets that do not trigger an immune response) so autoimmunity is a concern with any cancer vaccine. This concern is either as a consequence of cross reactivity of the specific immune response generated against cancer antigens (also present on normal organs) or as a consequence of immune modulation resulting from the immunological adjuvant or other components of the vaccine that may generate non-specific immune modulation. These concerns are largely mitigated, however, by the extensive experience and low toxicity profile consistently observed with the individual components of this vaccine in the clinic either alone or paired up with other components of this vaccine.
The Basis for Polyvalent Immunotherapy
There are at least three reasons for the expectation that carbohydrate vaccines against cancer should contain multiple antigens (be polyvalent). First, heterogeneity is an essential feature of malignancy with patient-to-patient tumor variability and even cell-to-cell heterogeneity in the same tumor is the norm. Second, heterogeneity also characterizes the immune responsiveness of immunized hosts as a consequence of a variety of known and unknown factors including previous immunologic experience and genetic background. The final basis for polyvalent vaccines is a consequence of the previous two reasons. Anti-tumor effector mechanisms are proportional to the amount of antibody bound to the cell surface, which will in turn be proportional to the number of different antigens in the vaccine.
Addressing the issue of tumor heterogeneity will also inform our decisions regarding which antibody candidates to develop. We expect that our current work aimed at improving the quality and control of manufacturing monoclonal antibodies will eventually allow us to explore the development of “cocktails” of mAbs which in turn would allow us to continue to improve the utility of antibodies against various cancers.
Sarcoma Vaccine
Background
Sarcomas are rare neoplasms (tumor that has caused a lump) that arise from the mesenchymal (connective tissue such as bone or cartilage) tissues of the body. According to the NCI’s website, in the United States, there are approximately 13,000 cases diagnosed each year, representing less than 1% of all new cancers. Of these sarcomas, roughly 80% originate from soft tissue, with the remainder originating from bone. Prognosis remains poor, with more than 5,000 patients in the US dying of disease each year. The overall prevalence of sarcoma patients in the US is thought to be approximately 100,000. All incidence and survival data from National Cancer Institute SEER data.
As in other malignancies, disease recurrence and metastasis are common in sarcoma. Metastases may involve any organ of the body, but, according to the NCI’s website approximately 20% of adult patients with extremity sarcomas will have isolated lung metastasis at some point during their disease course, with some amenable to complete surgical resection. Additional patients will have solitary or oligometastatic (cancer that has spread to multiple locations throughout the body) disease affecting other sites of the body that will be amenable to complete resection. Favorable prognostic indicators in recurrent sarcoma include a long disease-free interval from the time of primary resection, the number and location of metastatic lesions, and a long tumor doubling time.
Osteosarcomas (bone based sarcomas), rhabdomyosarcomas (sarcomas arising from muscle tissue), and other non-rhabdomyosarcomas such as Ewing sarcoma (tumor arising in bone or soft tissue and primarily occurring in teenagers and young adults) are high-risk sarcomas that occur most commonly in teens and young adults. According to the NCI’s website, approximately 30% of patients will present with metastases or recur following initial therapy for metastatic disease. These recurrences are generally treated with a combination of chemotherapy, surgery, and/or radiotherapy, with more than 90% of these patients achieving a complete response to therapy according to the NCI’s website.
Despite undergoing potentially curative surgical resection or combination therapy, according to an article by DA Potter and colleagues published in the Journal of Clinical Oncology in 1985, the majority of recurrent sarcoma patients die as a result of further recurrences. The overwhelming majority of pediatric patients ultimately succumb to their disease following the development of recurrent, chemoresistant disease, and their prognosis remains unacceptably poor despite aggressive multimodality treatment. The addition of chemotherapy to surgical resection has not been shown to improve outcome in adult sarcomas. Thus, in the majority of cases, the current standard of care following treatment of metastatic disease and the achievement of disease-free status is expectant management.
Sarcoma Vaccine Clinical Program
We initiated a randomized, multicenter, double-blind Phase II clinical trial in July of 2010. A total of 136 patients were enrolled. Patients who entered the study had stage IV metastatic disease and were cleared by surgery. Patients were vaccinated 10 times over 84 weeks and monitored throughout the study period. The study was powered to show a statistical improvement in both progression free survival (measured at the mid-point of the study) and overall survival. In October of 2013, the Company presented the mid-point results to the independent Drug Safety Monitoring Board, or DSMB. The DSMB concluded that there were no unanticipated or clinically worrisome safety concerns. Injection site reactions were the most common adverse events followed by fatigue, fever, and flu-like symptoms. In addition, the DSMB recommended that investigators and patients should remain blinded as to treatment assignment and the patients should continue to be followed to assess overall survival. In addition, given the acceptable safety profile observed in both arms of the study, the DSMB recommended that after investigators and patients are informed of the (blinded) results of this analysis and with their consent, the last of the patients still receiving vaccinations should be allowed to continue treatment.
In this study, the sarcoma vaccine elicited an antibody response intended to kill circulating tumor cells and micrometastases in all but one of the vaccinated patients. However, the DSMB concluded that the study did not reach statistical significance for its primary efficacy endpoint of a 50% improvement in time to recurrence. The study has not yet accumulated a sufficient number of events to evaluate the secondary endpoint of overall survival. Based on our discussions with the FDA prior to the initiation of the study, the overall survival endpoint will be considered the primary endpoint for the measurement of efficacy. As such we plan to follow all patients in the study until sufficient numbers of events (deaths) have occurred to allow analysis of this endpoint. We expect that the event threshold will be reached in late 2016 or early 2017.
Potential Commercial Opportunity
Sarcomas are a diverse group of malignant tumors that develop from fat, muscles, nerves, joints, blood vessels, bones, and deep skin tissues. Soft tissue sarcomas are more deadly in part due to the lack of detectable symptoms at early disease stages and prognosis remains poor, with more than 5,000 patients in the US dying of disease each year according to the NCI. The NCI estimates 5-year survival rates of 60%. Additionally, according to the NCI, an article in CA: A Cancer Journal for Clinicians by A. Jemal published in 2006, and articles published by the American Cancer Society, the overall prevalence of sarcoma patients in the US is thought to be approximately 100,000, recurrence rates vary depending on the particular subtype of sarcoma but generally range from 30% to 50% and patients whose sarcoma recurs have a significantly poorer prognosis which declines even further as the number of recurrences increase over the course of the disease.
The current standard of care for patients who have been successfully treated for their cancer and rendered free of detectable disease is watchful waiting. According to an article in The Lancet Oncology in 2012, additional treatments of chemotherapy or radiation have not been proven to prevent or prolong the time to onset of cancer recurrence. Consequently, we anticipate that the sarcoma vaccine will be added as an additional treatment to the current treatment paradigm and not displace an existing treatment. We expect that patients who have experienced one or more recurrences will be the initial candidates for vaccine therapy. This would be consistent with the early clinical trials. Over time, as the product demonstrates utility, we anticipate that usage will migrate toward earlier and earlier treatment to include patients who have been diagnosed and treated for sarcoma but not yet experienced a recurrence in an effort to block the progress of the cancer at an earlier and more likely productive time period.
Treatment is defined as a course of 10 vaccinations over 84 weeks as per the Phase II clinical trial protocol. Standard of care calls for patient check-ups quarterly after successful initial treatment to achieve the minimal disease status. The first 5 vaccinations require visits to the physician more frequently than quarterly but beyond that initial treatment sequence, the remaining vaccinations are delivered at the time of the standard check-up. Treatment can be given in the physician office setting with no special administration equipment required. There are substantial indirect costs associated with hospitalizations, short-term disability, and absenteeism resulting from cancer recurrence that can drive treatment costs higher. We project that annual revenue from a sarcoma vaccine could range from $150 million to $300 million annually based on internal projections considering the number of patients, the percentage of patients with metastatic disease, the cost of treatment, and market penetration rates.
The ultimate success of the sarcoma vaccine will depend on several factors, including, but not limited to the following: (i) The percentage of patients whose cancer does not recur or for whom recurrence is delayed, (ii) In those patients who respond to the vaccine, whether the prevention of recurrence or the delay of recurrence is for a clinically meaningful period of time, and (iii) The willingness of third-party payers and the government to pay for the addition of the vaccine therapy to the existing treatment paradigm. The clinical development program should answer the first two questions positively. As with almost all new therapies in cancer, the last question will require a substantial amount of work with these important participants in the healthcare system. If we can demonstrate reduced recurrence rates in sarcoma, we believe we can also demonstrate the financial benefits of reduced or unnecessary further treatments when recurrent sarcoma is prevented or delayed.
Ovarian Vaccine Program
Background
According to the NCI, ovarian cancer is the most lethal gynecologic cancer. According to materials available on the NCI’s website there are more than 21,800 new cases each year with almost 14,000 deaths per year. It is estimated that there are 174,000 surviving ovarian cancer patients. Recurrence rates are extremely high at 70% and 5-year survival is still very poor at just over 40%. The current standard treatment for patients with advanced ovarian cancer consists of aggressive surgical cytoreduction (resection of a tumor to the extent possible followed by radiation treatment) followed by taxane (chemical anti-cancer drug) and platinum-based chemotherapy. While the median overall survival for optimally debulked patients has increased to 65.6 months, less than 30% of patients will remain free of disease. Many patients will have chemotherapy-sensitive disease initially at recurrence, and can reenter successive remissions with additional treatment. Subsequent remissions are of progressively shorter duration until chemotherapy resistance uniformly develops. We believe that immune directed therapy is ideally suited for patients who are in clinical remission when the disease burden is lowest, and evaluating treatments designed to prolong the duration of such remissions remains a high priority. We also believe that antibodies are well suited for eradicating tumor cells from the bloodstream and eliminating early tissue invasion. Preclinical models have demonstrated the clearance of circulating tumor cells and the elimination of systemic micrometastasis through the use of both passively administered and vaccine induced antibodies.
Ovarian cancers express a rich array of cell-surface antigens. These include carbohydrate epitopes such as GM2, Globo-H, Lewisy, sialyl Tn, or STn, Tn, Thompson Friedreich antigen, or TF, and mucin 1, or MUC1. According to an article in Cancer Immunology Immunotherapy written by Livingston that was published in 1997, for the production of antibodies against defined cell-surface antigens such as these, the best approach has been described to include chemical conjugation of the antigen to a highly immunogenic carrier protein plus the use of a potent immunological adjuvant. The best carrier protein in our experience has been keyhole limpet hemocyanin (a sea creature such as a limpet or snail from which copper-based highly immunogenic blood is extracted), or KLH, and the best immunological adjuvant has been a saponin such as QS-21 or OPT-821. Pre-clinical data supports the hypothesis that polyvalent vaccines will likely be required due to tumor cell heterogeneity, heterogeneity of the human immune response, and the correlation between overall antibody titer against tumor cells and antibody effector mechanisms.
Ovarian Vaccine Clinical Program
A randomized, multicenter, double-blind Phase II clinical trial in ovarian cancer with a pentavalent (a vaccine that has multiple antigens) vaccine was initiated in July of 2010. While this vaccine was included in the group of vaccines exclusively licensed to us in 2008, a NIH grant award co-authored by Dr. Philip Livingston was made which fully funded the planned Phase II clinical trial. Management of the trial was assigned to the Gynecologic Oncology Group, or GOG. We contributed to the development of the Investigational New Drug Application (“IND”) and provided financial support for the manufacture of the clinical material. A total of 164 patients were enrolled. Patients who entered the study had metastatic ovarian cancer and have been treated with cytoreductive surgery and chemotherapy. They were in complete clinical remission as defined by CA-125 levels within normal, negative physical examination and no evidence of disease by CT scan. Patients were vaccinated 10 times over 84 weeks and monitored throughout the study period. The study was powered to show a statistical improvement in both progression free survival (measured at the mid-point of the study) and overall survival. The study has not achieved a sufficient number of events to trigger the mid-point analysis. Based on discussions with the principal investigator, the GOG plans to recommend that investigators and patients remain blinded as to treatment assignment and the patients should continue to be followed to assess overall survival. We anticipate that results from the overall survival endpoint will be announced in late 2016 or early 2017.

Neuroblastoma Vaccine
Introduction and Overview
Neuroblastoma is the most common extra-cranial solid tumor in children. According to the NCI and an article in the Annals of Pharmacology by Parsons and colleagues in 2013, there are approximately 700 new cases per year in the United States so it is certainly an orphan disease. According to the NCI SEER data, patients with high risk features, defined by clinical and tumor biologic parameters at diagnosis have an expected survival of only 45% despite intensive induction chemotherapy (very high dose chemotherapy), surgical resection, myeloablative consolidation chemotherapy with stem cell support, radiation,(radiation doses intended to eliminate the immune system of the patient followed by stem cell reconstitution of the system) focal radiation (precise pin-point radiation doses) and post-consolidation treatment (chemotherapy treatment post resection), with 13-cis-retinoic acid, or cisRA, and anti-GD2 mAb ch14.18 immunotherapy. We believe that these results, plus the potentially severe toxicities of chemotherapy and radiotherapy, are compelling reasons for pursuing novel therapeutic approaches.
In particular we believe that there is a need for therapies that selectively eliminate neuroblastoma cells in the setting of minimal or limited amounts of residual disease following intensive induction therapy. According to an article in Clinical Cancer Research by Matthay and Yu in 2012, neuroblastoma is unique in its abundant expression of the gangliosides GD2 and GD3. Each of these antigenic targets is an outstanding target for immune attack against neuroblastoma cells. In experimental animal studies conducted by Livingston and Ragupathi, administered or vaccine-induced antibodies against GD2, GD3 and other cell surface antigens were able to eliminate micrometastasis in settings similar to the treatment of patients in complete remission but with a high likelihood of relapse. The basis for emphasis on a bivalent (having two antigens raising an immune response to two targets) vaccine containing each of these agents are tumor cell heterogeneity, heterogeneity of the human immune response and the correlation between overall antibody titer against the tumor cell surface and effector mechanisms such as opsonization, complement-dependent cytotoxicity (how antibodies marshal other immune system cells to kill the cells to which they have attached, or CDC, or antibody dependent cellular cytotoxicity, or ADCC.

In a Phase I trial of a bivalent vaccine containing GD2-KLH, GD3-KLH and escalating doses of saponin adjuvant co-administered with oral Я-glucan in children with neuroblastoma has been completed (Kushner, et. al.) Safety, immunogenicity and the optimal saponin adjuvant dose were determined and the vaccinated subjects in this study were noted to have an unexpectedly favorable outcome. We believe that this experience provides the rationale for undertaking  a study in high-risk neuroblastoma subjects who are in second or subsequent complete remission or have only limited residual disease.
Results of a Recent Phase I trial of Bivalent Vaccine in Combination with Oral Я-glucan
MSK carried out a Phase I trial in subjects with high-risk neuroblastoma to assess the toxicity of escalating doses of the immunological adjuvant OPT-821 in a bivalent vaccine containing fixed doses of GD2L and GD3L, each covalently attached to the immunological carrier protein KLH (Kushner, 2012). The study subjects were in second (or later) complete, very good partial, or partial remission. Subjects received seven subcutaneous injections over 52 weeks,
Thirteen of the 15 subjects received the entire 12 months of protocol treatment. No dose limiting toxicity was noted in any of the subjects. Most subjects had detectable anti-GD2 or anti-GD3 antibodies. Twelve remain relapse-free at 21+-36+ (median 29+) months. One had a focal relapse (recurrence of the cancer at a specific spot) (supraclavicular node) at 21 months. Two other subjects had early focal relapses (2.3 and 4.6 months). PFS was 87+9% at 12 months and 78+11% at 24 months. Overall survival is 100% (follow-up >22months). These results are in marked contrast to the expected relapse rate at 12 months of 50% to 60%.
Clinical Plan
We have received the Phase I portion of an SBIR grant for support in production of the clinical trial material required for a planned Phase II clinical trial. The Company has also established a relationship with a consortium of thirteen academic hospital based neuroblastoma treatment programs called New Advances in Neuroblastoma Therapy, or NANT. We entered into a Letter of Intent with NANT and the NANT Scientific Review Committee has reviewed our jointly developed Phase II clinical protocol which was approved by this committee with only minor modifications. Because the market opportunity for a vaccine to treat recurrent neuroblastoma is very small, we have worked to bring in additional non-dilutive financing. We hope to expand the SBIR award to the Phase II portion of the grant which could offset $1 million in Phase II clinical expenses. We are currently conducting standard release and stability testing on the recently completed clinical material. We are planning to obtain the orally bioavailable immune system stimulant product that was used effectively in the Phase I trial at MSK. That product will be available in 2017.. We are currently evaluating the resource and capital requirements to file an IND to be able to initiate the Phase II clinical trial.  No timing can be given at this time regarding the filing of an IND.

 
Patents

We strive to protect the proprietary technology that we believe is important to our business, including seeking and maintaining patents intended to cover our vaccines and monoclonal antibody-based candidates, their methods of use and processes for their manufacture and any other inventions that are commercially important to the development of our business. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection.
 
As of January 25, 2016, we wereWe are the exclusive licensee or sole assignee or co-assignee of 1114 granted United States patents, 32 pending United States patent applications, 147 international patents and 319 pending international patent applications.  The patents and patent applications include claims to vaccine antigen conjugates, mixtures of vaccine antigen conjugates that makeup polyvalent vaccine candidates, processes for their preparation and their use as a vaccine.Two of the pending patent applications in the United States and 2 international patent applications have claims to human anti-sLea and anti-GD2 monoclonal antibodies, nucleic acids encoding the human anti-sLea and anti-GD2 monoclonal antibodies, processes for their preparation and their use as therapeutic agents.
 
Our success will depend significantly on our ability to obtain and maintain patents and other proprietary protection for commercially important technology, inventions and know-how related to our business, defend and enforce our patents, maintain our licenses to use intellectual property owned by third parties, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable patents and other proprietary rights of third parties. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen, and maintain our proprietary position in the field of anti-fungal agents.fully human monoclonal antibodies.
 
We believe that we have a sufficient intellectual property position and substantial know-how relating to the development and commercialization of our vaccine and monoclonal antibody-based candidates in the markets described herein, consisting of patents or patent applications that we have licensed from MSK or that we have filed ourselves. We cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our technology.
 
Our objective is to continue to expand our intellectual property estate by filing patent applications directed to our vaccine and monoclonal antibody programs. We intend to pursue, maintain, and defend patent rights, whether developed internally or licensed from third parties, and to protect the technology, inventions, and improvements that are commercially important to the development of our business.
 
Marketing and Sales
We currently do not have an internal sales force and do not intend to commercialize on our own any of our product candidates that receive FDA approval.  We intend to license, or enter into strategic alliances with, larger companies in the biopharmaceutical businesses, which are equipped to manufacture, market and/or sell our products, if any, through their well-developed manufacturing capabilities and distribution networks. We intend to license some or all of our worldwide patent rights to more than one third party to achieve the fullest development, marketing and distribution of any products we develop.
Manufacturing and Raw Materials
We currently use, and expect to continue the use of, contract manufacturers for the manufacture of our product candidates. Our contract manufacturers are subject to extensive governmental regulation. Regulatory authorities in our markets require that pharmaceutical products be manufactured, packaged and labeled in conformity with current cGMPs. We intend to establish a quality control and quality assurance program, which will include a set of standard operating procedures and specifications designed to ensure that our products are manufactured in accordance with cGMPs, and other applicable domestic and foreign regulations.
We currently do not have any clinical or commercial antibody-based therapeutic manufacturing capabilities. We may or may not manufacture the products we develop, if any. We intend to use contract manufacturers for the manufacture of our product candidates.
Competition
The drug development and medical diagnostic industries are characterized by rapidly evolving technology and intense competition.  Our competitors include development and diagnostic companies that have significantly more financial, technical, and marketing resources.  In addition, there are a significant number of biotechnology companies working on evolving technologies that may supplant our technology or make it obsolete.  Academic institutions, government agencies, and other public and private research organizations are also conducting research activities and may commercialize product candidates either on their own or through joint ventures that compete with one or more of our product candidates.  We are aware of certain development projects for products to prevent or treat certain diseases targeted by us.  The existence of these potential products or other products or treatments of which we are not aware, or products or treatments that may be developed in the future, may adversely affect the desirability and commercial success of any product candidate for which we receive FDA approval.
There are a number of companies working in the area of human antibody development and imaging that could compete in similar clinical areas, including disease detection, therapeutic response monitoring and minimal disease detection.  These companies include AbCellera Biologics, Inc., Agenus Inc., Atreca, Inc., Immunomedics, Inc., Theraclone Sciences Inc., and Trellis Bioscience.
Government Regulation

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug and Cosmetic Act and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. The FDA has very broad enforcement authority and failure to abide by applicable regulatory requirements can result in administrative or judicial sanctions being imposed on us, including warning letters, refusals of government contracts, clinical holds, civil or criminal penalties, injunctions, restitution, disgorgement of profits, recall or seizure of products, total or partial suspension of production or distribution, withdrawal of approval, refusal to approve pending applications, and criminal prosecution.

 
FDA Approval Process
 
We believe that our product candidates will be regulated by the FDA as drugs. No manufacturer may market a new drug until it has submitted a New Drug Application, or NDA, to the FDA, and the FDA has approved it. The steps required before the FDA may approve an NDA generally include:
 
preclinical laboratory tests and animal tests conducted in compliance with FDA’s good laboratory practice requirements;
● 
preclinical laboratory tests and animal tests conducted in compliance with FDA’s good laboratory practice requirements;
development, manufacture and testing of active pharmaceutical product and dosage forms suitable for human use in compliance with current good manufacturing practices, or GMP;
 
● 
development, manufacture and testing of active pharmaceutical product and dosage forms suitable for human use in compliance with current good manufacturing practices, or GMP;
the submission to the FDA of an investigational new drug application, or IND, for human clinical testing, which must become effective before human clinical trials may begin;
 
● 
the submission to the FDA of an investigational new drug application, or IND, for human clinical testing, which must become effective before human clinical trials may begin;
● 
adequate and well-controlled human clinical trials to establish the safety and efficacy of the product for its specific intended use(s);
● 
the submission to the FDA of a New Drug Application, or NDA; and
● 
FDA review and approval of the NDA.
adequate and well-controlled human clinical trials to establish the safety and efficacy of the product for its specific intended use(s);
the submission to the FDA of a New Drug Application, or NDA; and
FDA review and approval of the NDA.
 
Preclinical tests include laboratory evaluation of the product candidate, as well as animal studies to assess the potential safety and efficacy of the product candidate. The conduct of the pre-clinical tests must comply with federal regulations and requirements including good laboratory practices. We must submit the results of the preclinical tests, together with manufacturing information, analytical data and a proposed clinical trial protocol to the FDA as part of an IND, which must become effective before we may commence human clinical trials. The IND will automatically become effective 30 days after its receipt by the FDA, unless the FDA raises concerns or questions before that time about the conduct of the proposed trials. In such a case, we must work with the FDA to resolve any outstanding concerns before clinical trials can proceed. We cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate such trials. The study protocol and informed consent information for patients in clinical trials must also be submitted to an institutional review board for approval. An institutional review board may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the institutional review board’s requirements or may impose other conditions.
 
Clinical trials involve the administration of the product candidate to humans under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control. Clinical trials are typically conducted in three sequential phases, though the phases may overlap or be combined. In Phase 1, the initial introduction of the drug into healthy human subjects, the drug is usually tested for safety (adverse effects), dosage tolerance and pharmacologic action, as well as to understand how the drug is taken up by and distributed within the body. Phase 2 usually involves studies in a limited patient population (individuals with the disease under study) to:
evaluate preliminarily the efficacy of the drug for specific, targeted conditions;
 
determine dosage tolerance and appropriate dosage as well as other important information about how to design larger Phase 3 trials; and
evaluate preliminarily the efficacy of the drug for specific, targeted conditions;
determine dosage tolerance and appropriate dosage as well as other important information about how to design larger Phase 3 trials; and
identify possible adverse effects and safety risks.
 
identify possible adverse effects and safety risks.
Phase 3 trials generally further evaluate clinical efficacy and test for safety within an expanded patient population. The conduct of the clinical trials is subject to extensive regulation, including compliance with good clinical practice regulations and guidance.

 
The FDA may order the temporary or permanent discontinuation of a clinical trial at any time or impose other sanctions if it believes that the clinical trial is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. We may also suspend clinical trials at any time on various grounds.
 
The results of the preclinical and clinical studies, together with other detailed information, including the manufacture and composition of the product candidate, are submitted to the FDA in the form of an NDA requesting approval to market the drug.drug as well as a user fee of over $2 million. FDA approval of the NDA is required before marketing of the product may begin in the U.S. If the NDA contains all pertinent information and data, the FDA will “file” the application and begin review. The FDA may “refuse to file” the NDA if it does not contain all pertinent information and data. In that case, the applicant may resubmit the NDA when it contains the missing information and data. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of new drug applications. Most such applications for non-priority drug products are reviewed within 10 months. The review process, however, may be extended by FDA requests for additional information, preclinical or clinical studies, clarification regarding information already provided in the submission, or submission of a risk evaluation and mitigation strategy. The FDA may refer an application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. Before approving an NDA, the FDA will typically inspect the facilities at which the product candidate and/or the active pharmaceutical ingredient is manufactured and will not approve the product candidate unless GMP compliance is satisfactory. FDA also typically inspects facilities responsible for performing animal testing, as well as clinical investigators who participate in clinical trials. The FDA may refuse to approve an NDA if applicable regulatory criteria are not satisfied, or may require additional testing or information. The FDA may also limit the indications for use and/or require post-marketing testing and surveillance to monitor the safety or efficacy of a product. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing.
 
The testing and approval process requires substantial time, effort and financial resources, and our product candidates may not be approved on a timely basis, if at all. The time and expense required to perform the clinical testing necessary to obtain FDA approval for regulated products can frequently exceed the time and expense of the research and development initially required to create the product. The results of preclinical studies and initial clinical trials of our product candidates are not necessarily predictive of the results from large-scale clinical trials, and clinical trials may be subject to additional costs, delays or modifications due to a number of factors, including difficulty in obtaining enough patients, investigators or product candidate supply. Failure by us to obtain, or any delay in obtaining, regulatory approvals or in complying with requirements could adversely affect the commercialization of product candidates and our ability to receive product or royalty revenues.
 
Other Regulatory Requirements
 
After approval, drug products are subject to extensive continuing regulation by the FDA, which include company obligations to manufacture products in accordance with Good Manufacturing Practice, or GMP, maintain and provide to the FDA updated safety and efficacy information, report adverse experiences with the product, keep certain records and submit periodic reports, obtain FDA approval of certain manufacturing or labeling changes, and comply with FDA promotion and advertising requirements and restrictions. Failure to meet these obligations can result in various adverse consequences, both voluntary and FDA-imposed, including product recalls, withdrawal of approval, restrictions on marketing, and the imposition of civil fines and criminal penalties against the NDA holder. In addition, later discovery of previously unknown safety or efficacy issues may result in restrictions on the product, manufacturer or NDA holder.
 
We and any manufacturers of our products are required to comply with applicable FDA manufacturing requirements contained in the FDA’s GMP regulations. GMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation. The manufacturing facilities for our products must meet GMP requirements to the satisfaction of the FDA pursuant to a pre-approval inspection before we can use them to manufacture our products. We and any third-party manufacturers are also subject to periodic inspections of facilities by the FDA and other authorities, including procedures and operations used in the testing and manufacture of our products to assess our compliance with applicable regulations.

 
With respect to post-market product advertising and promotion, the FDA imposes a number of complex regulations on entities that advertise and promote pharmaceuticals, which include, among others, standards for direct-to-consumer advertising, promoting drugs for uses or in patient populations that are not described in the drug’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses.
 
Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before the change can be implemented. An NDA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in reviewing NDAs.
 
Adverse event reporting and submission of periodic adverse experience reports is required following FDA approval of an NDA. The FDA also may require post-marketing testing, known as Phase 4 testing, risk evaluation and minimization strategies, action plans and surveillance, as well as annual reports on matters relating to the NDA, to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.
 
Outside the United States, our ability to market a product is contingent upon receiving marketing authorization from the appropriate regulatory authorities. The requirements governing marketing authorization, pricing and reimbursement vary widely from jurisdiction to jurisdiction. At present, foreign marketing authorizations are applied for at a national level, although within the European Union registration procedures are available to companies wishing to market a product in more than one European Union member state.
 
We are also subject to various environmental, health and safety regulations including those governing laboratory procedures and the handling, use, storage, treatment, and disposal of hazardous materials. From time to time, and in the future, our operations may involve the use of hazardous materials.
Orphan Drugs
Under the Orphan Drug Act of 1983, the FDA may grant orphan drug designation to drugs or biologics intended to treat a rare disease or condition, which is generally defined as a disease or condition that affects fewer than 200,000 individuals in the United States. Orphan drug designation must be requested before submitting an NDA. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. The first applicant to receive FDA approval for a particular active ingredient to treat a particular disease with FDA orphan drug designation is entitled to a seven-year exclusive marketing period in the United States for that product, for that indication. During the seven-year exclusivity period, the FDA may not approve any other applications to market the same drug or biologic for the same disease, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the NDA application user fee.
Non-U.S. Regulation
Before our products can be marketed outside of the United States, they are subject to regulatory approval of the respective authorities in the country in which the product should be marketed. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. Even if a product is approved by a regulatory authority, satisfactory prices might not be approved for such product.
In Europe, marketing authorizations may be submitted at a centralized, a decentralized or national level; however, the centralized procedure is mandatory for the approval of biotechnology products and provides for the grant of a single marketing authorization that is valid in all European Union member states. There can be no assurance that the chosen regulatory strategy will secure regulatory approval on a timely basis or at all.
While we intend to market our products outside the United States in compliance with our respective license agreements, we have not made any applications with non-U.S. authorities and have no timeline for such applications or marketing.

Legal Proceedings
 
From time to time, we have become involved in various legal proceedings that arise in the ordinary course of business or otherwise. Legal proceedings are subject to inherent uncertainties as to timing, outcomes, costs, expenses and time expenditures by our management and others on our behalf.

The suit alleged, alleging the defendants breached certain fiduciary duties, or aided and abetted a breach of fiduciary duties, in connection with the Company’s mergerour Merger with MabVax Therapeutics. In support of their purported claims, the plaintiff alleged, among other things, that the Company’s board has historically failed to fulfill its fiduciary duty to its stockholders, and claiming with respect to the Series B Private Placement and the Merger, that such transactions involved an inadequate sales process and included preclusive deal protection devices, and that the Company’s board of directors would receive personal benefits not available to its public stockholders as a result of the Merger. The plaintiff sought to enjoin the Merger and obtain damages as well as attorneys’ and expert fees and costs.
On June 29, 2014, the parties entered into a Stipulation and Settlement (the “Settlement”), pursuant to which the Company agreed to file with the SEC certain supplemental disclosures  No expenses were incurred in 2016 in connection with the merger. The Settlement was subject to certain confirmatory discovery to be undertaken by the plaintiff and to the Parties’ agreement on the payment of the plaintiff’s attorneys’ fees and expenses.
On July 16, 2014, the Company and all other parties to the litigation entered into an agreement which, if consummated, would settle the litigation (the “Proposed Settlement”). Among many other terms, under the Proposed Settlement the Company and all defendants will receive a broad release of any and all claims pertaining to the Series B Private Placement, the Merger, the prior disclosure and a wide variety of other matters. The Proposed Settlement also calls for the parties to ask the court to, among other things, enter orders enjoining other stockholders from bringing similar actions, certifying the putative settlement class, and approving the Proposed Settlement as a fair, final, and binding resolution of the litigation. Under the Proposed Settlement, the Company and the other defendants have expressly denied the allegations of the complaint and denied engaging in any other misconduct, nor will any of them make any paymentthis lawsuit or in any respect amend the negotiated terms of the since-consummated Series B Private Placement and merger. Finally, under the Proposed Settlement, the Company and the other defendants have not agreed to pay any legal fees, or reimburse any expenses, allegedly incurred by the plaintiffs who filed the complaint; instead, the Company expects that counsel for those plaintiffs will present any such disputed claim for legal fees and expenses to the court for resolution.
On April 20, 2015, the Parties made an application for an Order for Notice and Scheduling of Hearing of Settlement in accordance with a Stipulation of Settlement dated as of April 20, 2015 (the “Action”), which sets forth the terms and conditions for settlement and which provides for dismissal of the Action with prejudice.  The Order after Hearing on June 12, 2015, provided preliminary approval of the settlement that was agreed to by the Parties, in which the Company provided supplemental disclosures in the definitive proxy filed with the SEC on June 30, 2014.  Notice of the action as a class action was sent to class members in July 2015.

On September 18, 2015, an Order and Final Judgment was entered by the Superior Court of the State of California, approving the settlement that was agreed upon by both parties and closing the case.  The Company anticipates that there will be no additional future expenses incurred in this action by the Company after the September 30, 2015 balance sheet date which would not be offset by insurance.settlement.

BOARD OF DIRECTORS COMMITTEES AND MEETINGS
 
BOARD LEADERSHIP STRUCTURE
 
The Board of Directors is currently chaired by the President and Chief Executive Officer of the Company, Mr. Hansen. The Company believes that combining the positions of Chief Executive Officer and Chairman of the Board of Directors helps to ensure that the Board of Directors and management act with a common purpose. Integrating the positions of Chief Executive Officer and Chairman can provide a clear chain of command to execute the Company’s strategic initiatives. The Company also believes that it is advantageous to have a Chairman with an extensive history with and knowledge of the Company, and extensive technical and industry experience. Notwithstanding the combined role of Chief Executive Officer and Chairman, key strategic initiatives and decisions involving the Company are discussed and approved by the entire Board of Directors. In addition, meetings of the independent directors of the Company are regularly held, which Mr. Hansen does not attend. The Company believes that the current leadership structure and processes maintains an effective oversight of management and independence of the Board of Directors as a whole without separate designation of a lead independent director. However, the Board of Directors will continue to monitor its functioning and will consider appropriate changes to ensure the effective independent function of the Board of Directors in its oversight responsibilities.
 
ROLE OF THE BOARD IN RISK OVERSIGHT
 
One of the Board of Director’s key functions is informed oversight of the Company’s risk management process. The Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various Board of Directors standing committees that address risks inherent in their respective areas of oversight. In particular, our Board of Directors is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. The Audit Committee considers and discusses with management the Company’s major financial risk exposures and related monitoring and control of such exposures as well as compliance with legal and regulatory requirements. The Nominating & Governance Committee monitors the effectiveness of our corporate governance guidelines. The Compensation Committee assesses and monitors whether our compensation policies and programs have the potential to encourage excessive risk-taking. Any findings regarding material risk exposure to the Company are reported to and discussed with the Board of Directors.

 
INDEPENDENCE OF THE BOARD OF DIRECTORS AND ITS COMMITTEES
 
After review of all relevant transactions or relationships between each director and nominee for director, or any of his or her family members, and the Company, its senior management and its Independent Registered Public Accounting Firm, the Board of Directors has determined that all of the Company’s directors and the Company’s nominees for director are independent within the meaning of the applicable NASDAQ listing standards, except Mr. Hansen, the Chairman of the Board of Directors, Chief Executive Officer and President, of the Company, and Dr. Livingston, Chief Science Officer.Officer; and Dr. Ravetch. As required under the NASDAQ listing standards, the Company’s independent directors meet in regularly scheduled executive sessions at which only independent directors are present. The Board of Directors met 116 times and acted by unanimous written consent 911 times during the fiscal year ended December 31, 2015.2016.  Each member of the Board of Directors attended 75% or more of the aggregate of the meetings of the Board of Directors held in the last fiscal year during the period for which he was a director and of the meetings of the committees on which he served held in the last fiscal year during the period for which he was a committee member, except Dr.Philip Livingston who was unable to attend certain meetings due to travel and other commitments.  Although the Company is not currently NASDAQ-listed we believe it is in the Company’s interests to comply with these standards both as a matter of good governance and to facilitate any future re-listing.
 
The Board of Directors has three committees: anthe Audit Committee, athe Compensation Committee and athe Nominating & Governance Committee. Below is a description of each committee of the Board of Directors. The Board of Directors has determined that each member of each committee meets the applicable rules and regulations regarding “independence” and that each member is free of any relationship that would interfere with his individual exercise of independent judgment with regard to the Company.
 
AUDIT COMMITTEE
 
The Audit Committee of the Board of Directors oversees the Company’s corporate accounting and financial reporting process. For this purpose, the Audit Committee performs several functions. The Audit Committee, among other things: evaluates the performance, and assesses the qualifications, of the Independent Registered Public Accounting Firm; determines and pre-approves the engagement of the Independent Registered Public Accounting Firm to perform all proposed audit, review and attest services; reviews and pre-approves the retention of the Independent Registered Public Accounting Firm to perform any proposed, permissible non-audit services; determines whether to retain or terminate the existing Independent Registered Public Accounting Firm or to appoint and engage a new Independent Registered Public Accounting Firm for the ensuing year; confers with management and the Independent Registered Public Accounting Firm regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; reviews the financial statements to be included in the Company’s Annual Report on Form 10-K and recommends whether or not such financial statements should be so included; and discusses with management and the Independent Registered Public Accounting Firm the results of the annual audit and review of the Company’s quarterly financial statements.
 
The Audit Committee is currently composed of four outside directors: Mr. Maier, Mr. Cohen, Mr. Hoffman and Mr. Varvaro, as of December 31, 2015.2016. The Audit Committee met 65 times and acted two times by written consent during the fiscal year ended December 31, 2015.2016. The Audit Committee Charter was last amended in March 2015 and is available on the Company’s website, www.mabvax.com.
 
The Board of Directors periodically reviews the NASDAQ listing standards’ definition of independence for Audit Committee members and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A) of the NASDAQ listing standards and Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, as amended). Although the Company is not currently NASDAQ-listed we believe it is in the Company’s interests to comply with these NASDAQ standards both as a matter of good governance and to facilitate any future re-listing. The Board of Directors has determined that Mr. Maier qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board of Directors made a qualitative assessment of Mr. Maier’s level of knowledge and experience based on a number of factors, including his formal education and his service in executive capacities having financial oversight responsibilities. These positions include Chief Financial Officer, Senior Vice President, and member of the boards of directors and audit committees of, a number of biotechnology and genomics companies, pursuant to which he has experience preparing, reviewing and supervising the preparation of financial reports. In addition, Mr. Maier holds an M.B.A from Harvard Business School. For further information on Mr. Maier’s experience, please see his biography above.

Each of Jeffrey V. Ravetch, M.D., Ph.D., Robert E. Hoffman, a Kenneth M. Cohen and Thomas Varvaro served on our compensation committee in 2015. No member of our compensation committee has at any time been an employee of ours. None of our executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.
 
NOMINATING & GOVERNANCE COMMITTEE
 
The Nominating & Governance Committee of the Board of Directors is responsible for, among other things: identifying, reviewing and evaluating candidates to serve as directors of the Company; reviewing, evaluating and considering incumbent directors; recommending to the Board of Directors for selection candidates for election to the Board of Directors; making recommendations to the Board of Directors regarding the membership of the committees of the Board of Directors; and assessing the performance of the Board of Directors.
 
The Nominating & Governance Committee is currently composed of fourfive outside directors: Mr.Messrs. Cohen, Mr.Eisenberg, Hoffman, Mr. Maier and Mr. Varvaro, as of December 31, 2015.2016.  On May 6, 2016, Mr. Eisenberg was appointed to the Nominating & Governance Committee.   All members of the Nominating & Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the NASDAQ listing standards). The Nominating & Governance Committee met once3 times during the fiscal year ended December 31, 2015.2016. The Nominating & Governance Committee Charter was last amended in March 2015 and is available on the Company’s website, www.mabvax.com.
 
The Nominating & Governance Committee has not established any specific minimum qualifications that must be met for recommendation for a position on the Board of Directors. Instead, in considering candidates for director the Nominating & Governance Committee will generally consider all relevant factors, including among others the candidate’s applicable education, expertise and demonstrated excellence in his or her field, the usefulness of the expertise to the Company, the availability of the candidate to devote sufficient time and attention to the affairs of the Company, the candidate’s reputation for personal integrity and ethics and the candidate’s ability to exercise sound business judgment. Other relevant factors, including diversity, experience and skills, will also be considered. Candidates for director are reviewed in the context of the existing membership of the Board of Directors (including the qualities and skills of the existing directors), the operating requirements of the Company and the long-term interests of its stockholders.
 
The Nominating & Governance Committee considers each director’s executive experience leading biopharmaceutical companies, his familiarity and experience with the various operational, scientific and/or financial aspects of managing companies in our industry, and his involvement in building collaborative biopharmaceutical development and commercialization relationships.
With respect to diversity, the Nominating & Governance Committee seeks a diverse group of individuals who have executive leadership experience in life sciences companies, and a complementary mix of backgrounds and skills necessary to provide meaningful oversight of the Company’s activities. As a clinical stage drug development company focused on discovering and developing small molecule drugs, we seek directors who have experience in the medical, regulatory and pharmaceutical industries in general, and also look for individuals who have experience with the operational issues that we face in our dealings with clinical and pre-clinical drug development, collaborations with third parties and commercialization and manufacturing issues. Some of our directors have strong financial backgrounds and experience in dealing with public companies, to help us in our evaluation of our operations and our financial model. We also face unique challenges as we implement our strategy to develop, manufacture and commercialize our products by entering into relationships with pharmaceutical companies. The Nominating & Governance Committee annually reviews the Board’s composition in light of the Company’s changing requirements. The Nominating & Governance Committee uses the Board of Director’s network of contacts when compiling a list of potential director candidates and may also engage outside consultants. Pursuant to its charter, the Nominating & Governance Committee will consider, but not necessarily recommend to the Board of Directors, potential director candidates recommended by stockholders. All potential director candidates are evaluated based on the factors set forth above, and the Nominating & Governance Committee has established no special procedure for the consideration of director candidates recommended by stockholders.
  
Director Nominations
 
There have been no material changes to the procedures by which a stockholder may recommend nominees to the Board of Directors since our last disclosure of these procedures.
 
STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

Stockholders who wish to communicate with the Board of Directors may do so by sending a written communication addressed as follows: Board Communication, MabVax Therapeutics Holdings, Inc., 1158811535 Sorrento Valley Rd., Suite 20,400, San Diego, CA 92121.

Employment Severance and Change of Control Arrangements
-54-
We entered into an employment agreement with Michael M. Wick, M.D., Ph.D. in August 1999 upon his promotion to the position of Chief Executive Officer. In December 1999, Dr. Wick was elected Chairman of the Board of Directors effective January 2000. On December 17, 2008, we entered into an amended and restated employment agreement, or the Employment Agreement, with Dr. Wick to clarify the manner in which such employment agreement complies with the final regulations under Section 409A of the U.S. Internal Revenue Code. The Employment Agreement superseded and replaced the employment agreement entered into in August 1999. According to the Employment Agreement, either the Company or Dr. Wick may terminate his employment at any time for any reason. Per the agreement if Dr. Wick were to be terminated without cause, he would have been entitled to receive as severance continued payment of his base salary and health care benefits for twelve months. We will also accelerate the vesting of his then unvested stock options as to the number of shares that would have vested in the ordinary course in the first twelve months following his termination date, with such vesting effective as of his termination date. Dr. Wick’s benefits pursuant to the Employment Agreement were subject to his signing of a general waiver or release of the Company. See the section “Effect of the Merger on Executive Compensation Arrangements” regarding Dr. Wick’s release and severance obligations following the merger.

In February 2003, we adopted the Telik, Inc. Change of Control Severance Benefit Plan, or the Severance Plan. On December 17, 2008, the Compensation Committee of the Board of Directors adopted an amendment to the Severance Plan to clarify the manner in which such plan complies with the final regulations under Section 409A. The Severance Plan provided eligible participants with severance benefits in the event that a participant’s employment with the Company were to be terminated, voluntarily or involuntarily, without cause within one year after a change of control, provided that the eligible participant signs a general waiver or release prior to receipt of the benefits. Such benefits included cash severance, payment of premiums under employee benefits plans, COBRA continuation coverage, accelerated vesting of unvested stock options and additional payments if the amounts which a participant would receive in connection with a change in control of the Company would constitute a “parachute payment” or be subject to excise tax.
The Severance Plan provided that, to the extent designated by the Compensation Committee or the Chief Executive Officer, the Chief Operating Officer, Chief Financial Officer, Senior Vice Presidents, Vice Presidents and others would be eligible to participate in the Severance Plan. On February 21, 2003, the Board of Directors designated Dr. Wick as eligible to participate in the Severance Plan. Under the Severance Plan, Dr. Wick, as the Chief Executive Officer, is eligible to receive (1) full accelerated vesting of any unvested stock options then held, (2) a lump sum cash payment equal to two times the greater of: (i) the sum of his base salary and the greater of: (a) the annual cash bonus paid to him in the prior year; or (b) his Annual Target Bonus as in effect on the date of termination; or (ii) the sum of his base salary and the greater of: (a) the annual cash bonus paid to him in the prior year; or (b) his Annual Target Bonus as in effect immediately prior to the Change of Control; and (3) continuation of health benefits for up to 24 months and COBRA continuation coverage. Dr. Wick would also have been entitled to additional payments if the amounts he would receive in connection with a change in control of MabVax Therapeutics Holdings, Inc. would constitute a “parachute payment” or be subject to excise tax. Dr. Wick’s benefits under the Severance Plan, when applicable, would have superseded the severance benefits under his employment contract.
Effect of the Merger on Our Executive and Director Compensation Arrangements
 
In connection with the Merger, we obtained release agreements from each of Michael M. Wick, M.D., Ph.D., Gail L. Brown, M.D., William P. Kaplan, Esq., Steven R. Schow, Ph.D., and Wendy K. Wee to release any potential claims against MabVax Therapeutics with respect the termination of their employment with or service to the Company, including all claims under the Severance Plan, and provided that each would resign from their respective officer positions upon the consummation of the merger in exchange for cash payments as provided below:

Director Independence
After review of all relevant transactions or relationships between each director and nominee for director, or any of his or her family members, and the Company, its senior management and its Independent Registered Public Accounting Firm, the Board of Directors has determined that all of the Company’s directors are independent within the meaning of the applicable SEC rules and the NASDAQ listing standards, except Mr. Hansen, the Chairman of the Board of Directors and Chief Executive Officer and President of the Company, and Dr. Livingston, Chief Science Officer of the Company.  Although the Company is not currently NASDAQ-listed we believe it is in the Company’s interests to comply with these standards both as a matter of good governance and to facilitate any future re-listing.


 The following description of our capital stock summarizes the material terms and provisions of our common stock and preferred stock.
Authorized Capital Stock
Our authorized capital stock consists of 150,000,000 shares of common stock, $0.01 par value, and 15 million shares of preferred stock, $0.01 par value. As of January 25, 2016, there were 29,036,272 shares of common stock outstanding, 185,039 shares of Series D Preferred Stock outstanding, and 33,333 shares of Series E Preferred Stock outstanding.
Common Stock
The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock and preferred stock entitled to vote in any election of directors may elect all of the directors standing for election. Subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably such dividends as may be declared by the board of directors out of funds legally available therefor. Upon the liquidation, dissolution or winding up of the Company, holders of our common stock are entitled to share ratably together with the holders of our Series C Preferred Stock, Series D Preferred Stock, and Series E Preferred Stock in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no preemptive rights and no right to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of common stock are fully paid and non-assessable.
Preferred Stock
Pursuant to our certificate of incorporation, our board of directors has the authority, without further action by the stockholders, to issue up to 15,000,000 shares of preferred stock, in one or more series. Our board shall determine the rights, preferences, privileges and restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of any series. The issuance of preferred stock could adversely affect the voting power, conversion or other rights of holders of common stock. Preferred stock could be issued quickly with terms calculated to delay or prevent a change in control of the Company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.
0% Series D Convertible Preferred Stock
Pursuant to the Series D Certificate of Designations, we designated 1,000,000 shares of our blank check preferred stock as Series D preferred stock. Each share of Series D preferred stock has a stated value of $0.01 per share. In the event of a liquidation, dissolution or winding up of our company, each share of Series D preferred stock will be entitled to a per share preferential payment equal to the stated value. Each share of Series D preferred stock is convertible into 100 shares of common stock. The conversion ratio is subject to adjustment in the event of stock splits, stock dividends, combination of shares and similar recapitalization transactions. We are prohibited from effecting the conversion of the Series D preferred stock to the extent that, as a result of such conversion, the holder beneficially owns more than 4.99% (provided that certain investors elected to block their beneficial ownership initially at 2.49), in the aggregate, of the issued and outstanding shares of our common stock calculated immediately after giving effect to the issuance of shares of common stock upon the conversion of the Series D preferred stock. Each share of Series D preferred stock entitles the holder to vote on all matters voted on by holders of common stock. With respect to any such vote, each share of Series D preferred stock entitles the holder to cast such number of votes equal to the number of shares of common stock such shares of Series D preferred stock are convertible into at such time, but not in excess of the beneficial ownership limitation.
On March 25, 2015, we entered into the Exchange Agreements with certain holders of our then outstanding Series A-1 Preferred Stock and A-1 Warrants and holders of our Series B Preferred Stock and Series B Warrants, all previously issued by us. Pursuant to the Exchange Agreements, the holders exchanged such securities and relinquished any and all other rights they may in connection therewith, their respective governing agreements and certificates of designation, including any related registration rights, in exchange for the Exchanged Securities.
As of January 25, 2016, 185,039 shares of our Series D Preferred Stock are outstanding and convertible into 18,503,900 shares of our common stock.
0% Series E Convertible Preferred Stock
On March 30, 2015, we filed a Certificate of Designations, Preferences and Rights of the 0% Series E Convertible Preferred Stock with the Delaware Secretary of State, designating one hundred thousand shares of preferred stock as 0% Series E Convertible Preferred Stock.
The Series E Preferred Shares are convertible into shares of common stock based on a conversion calculation equal to the stated value of the of such Series E Preferred Share, plus all accrued and unpaid dividends, if any, on such Series E Preferred Share, as of such date of determination, divided by the conversion price. The stated value of each Series E Preferred Share is $75 and the initial conversion price is $0.75 per share, each subject to adjustment for stock splits, stock dividends, recapitalizations, combinations, subdivisions or other similar events. In addition, during the period proscribed by the Certificate of Designations, subject to certain exceptions, in the event the Company issues or sells, or is deemed to issue or sell, shares of common stock at a per share price that is less than the conversion price then in effect, the conversion price shall be reduced to such lower price. We are prohibited from effecting a conversion of the Series E Preferred Shares to the extent that, as a result of such conversion, the holder would beneficially own more than 4.99% of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock upon conversion of the Series E Preferred Shares, which beneficial ownership limitation may be increased by the holder up to, but not exceeding, 9.99%. Each holder is entitled to vote on all matters submitted to stockholders of the Company, and shall have the number of votes equal to the number of shares of common stock issuable upon conversion of such holder’s Series E Preferred Shares, but not in excess of the beneficial ownership limitations. The Series E Preferred Shares bear no interest.
As of April 10, 2015, we entered into separate subscription agreements with accredited investors relating to the issuance and sale of an additional $6,718,751 of units at a purchase price of $0.75 per unit, with each unit consisting of one share of  common stock (or, at the election of any investor who, as a result of receiving common stock would hold in excess of 4.99% of our issued and outstanding common stock, shares of our newly designated Series E Preferred Shares) and a thirty month warrant to purchase one half of one share of common stock at an initial exercise price of $1.50 per share. In connection with the above described offering we issued $2,500,000 of units consisting of Preferred Shares.
We has also granted each investor, prior to the expiration of 24 months following the final closing date of the offering, a right of participation in our financings. In the event we conduct certain private or public offerings of our securities, each investor has agreed, if requested by the underwriter or placement agent so engaged by us in connection with such offering, to refrain from selling any of our securities for a period of up to 60 days.
We have undertaken, pursuant to the registration rights agreement between the Company and each of the investors to file a registration statement to register 25% of the total number of shares of common stock issued in the offering and 25% of the shares of common stock underlying she Series E Preferred Shares, within sixty days following the final closing date of the April Private Placement, to have such registration statement declared effective by the Securities and Exchange Commission within one hundred and twenty days from such filing date and to maintain the effectiveness of the registration statement until all of the common stock and Series E Conversion Shares, have been sold or are otherwise able to be sold pursuant to Rule 144. In the event the Company fails to file within the sixty day period or have such registration statement declared effective within the one hundred and twenty day period, we are obligated to pay interest charges of 1% per month to the Series E Investors for each month during which such filing is not made and/or effectiveness obtained, such interest charges being subject to certain exceptions. On June 9, 2015, the Company received the requisite approval of the investors to amend the filing deadline to June 9, 2015 and on August 4, 2015, received further approval to extend the filing deadline to October 9, 2015 and for the waiver of any payments for liquidated damages in connection with the extension of the filing deadline.  Furthermore, on October 12, 2015, the Company received the required approval to suspend the Company’s registration obligations under the Registration Rights Agreements and the Subscription Agreements during any period when the “Standstill” provision set forth in 5(u) of the Subscription Agreements is in effect.
On April 14, 2015, as a condition to participation by OPKO and FGIT in the offering, we entered into an Escrow Deposit Agreement with Signature Bank N.A. and OPKO, as amended on June 22, 2015, pursuant to which the subscriptions of OPKO and FGIT, totaling, $3.5 million, were to be deposited into and held at Signature Bank as escrowed funds.  The escrowed funds were released to the Company on June 30, 2015 as part of a letter agreement giving OPKO the right, but not the obligation, until June 30, 2016, to nominate and appoint up to two additional members of the Company’s Board of Directors, or to approve the person(s) nominated by the Company.  The nominees will be subject to satisfaction of standard corporate governance practices and any applicable national securities exchange requirements.

Anti-Takeover Effects of Provisions of Delaware Law and Our Charter Documents.
Delaware Takeover Statute. We are subject to the provisions of Section 203 of the Delaware General Corporation Law, or the DGCL. In general, the statute prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. For purposes of Section 203, a business combination includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and an interested stockholder is a person who, together with affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation’s voting stock.
Charter Documents. Our certificate of incorporation requires that any action required or permitted to be taken by its stockholders must be effected at a duly called annual or special meeting of stockholders and may not be effected by a consent in writing. Additionally, our amended and restated certificate of incorporation:
substantially limits the use of cumulative voting in the election of directors;
provides for a board of directors, classified into three classes of directors;
provides that the authorized number of directors may be changed only by resolution of our board of directors;
our board of directors may appoint new directors to fill vacancies or newly created directorships; and
authorizes our board of directors to issue blank check preferred stock to increase the amount of outstanding shares.
Our bylaws provide that candidates for director may be nominated only by our board of directors or by a stockholder who gives written notice to us no later than 90 days prior to nor earlier than 120 days prior to the first anniversary of the last annual meeting of stockholders, provided, however, that in the event that the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of the preceding year’s annual meeting, notice should be delivered not earlier than 120 days prior to the annual meeting nor later than the later of 90 days prior to such annual meeting or 10 days after the first public announcement of the date of such annual meeting. Our bylaws also limit who may call a special meeting of stockholders.
Delaware law and these charter provisions may have the effect of deterring hostile takeovers or delaying changes in control of our management, which could depress the market price of our common stock.

SELLING SHAREHOLDERS
We are registering an aggregate of 3,904,830 Resale Shares for resale by the Selling Shareholders listed in the table below. All expenses incurred with respect to the registration of the Common Stock will be paid by us, but we will not be obligated to pay any underwriting fees, discounts, commissions or other expenses incurred by the Selling Shareholders in connection with the sale of such shares.
The Selling Shareholders may also resell all or a portion of their securities in reliance upon Rule 144 under the Securities Act provided that they meet the criteria and conform to the requirements of that rule or by any other available means.
The Selling Shareholders named below may from time to time offer and sell pursuant to this prospectus up to 3,904,830 Resale Shares. The shares of our Common Stock included in the Resale Shares were issued to the Selling Shareholders in the transaction described in the footnotes to the following table.
The following table sets forth:
·the name of the Selling Shareholders;
·the number and percent of shares of our Common Stock that the Selling Shareholders beneficially owned prior to the offering for resale of the shares under this prospectus;
·the number of shares of our Common Stock that may be offered for resale for the account of the Selling Shareholders under this prospectus; and
·the number and percent of shares of our Common Stock to be beneficially owned by the Selling Shareholders after the offering of the Resale Shares (assuming all of the offered Resale Shares are sold by the Selling Shareholders).
The number of shares in the column “Number of Shares Being Offered” represents all of the shares that each Selling Shareholder may offer under this prospectus. We do not know how long the Selling Shareholders will hold the shares before selling them or how many shares they will sell, and we currently have no agreements, arrangements or understandings with any of the Selling Shareholders regarding the sale of any of the Resale Shares.
This table is prepared solely based on information supplied to us by the Selling Shareholders, any Schedules 13D or 13G and Forms 3 and 4, and other public documents filed with the SEC. The applicable percentages of beneficial ownership are based on an aggregate of 29,036,272 shares of our common stock issued and outstanding on January 25, 2016.
Except as noted in the footnotes to the table below, to our knowledge, none of the Selling Shareholders has held any position or office or had any other material relationship with us or any of our predecessors or affiliates within the past three years other than as a result of the ownership of our securities. None of the Selling Shareholders is a broker-dealer or affiliate of a broker-dealer. See “Plan of Distribution” for additional information about the Selling Shareholders and the manner in which the Selling Shareholders may dispose of their shares. Beneficial ownership has been determined in accordance with the rules of the SEC, and generally means that a person has beneficial ownership of a security if he, she or it possesses sole or shares voting or investment power of that security, and includes options that are currently exercisable or exercisable within 60 days. Our registration of these securities does not necessarily mean that the Selling Shareholders will sell any or all of the securities covered by this prospectus.

Each selling stockholder of the common stock and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock on The OTCQB or any other stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling stockholder may use any one or more of the following methods when selling shares:
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
settlement of short sales entered into after the effective date of the registration statement of which this prospectus is a part;
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
a combination of any such methods of sale; or
any other method permitted pursuant to applicable law.
The selling stockholders may also sell shares under Rule 144 under the Securities Act of 1933, as amended, if available, rather than under this prospectus.
Broker-dealers engaged by the selling stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440.
In connection with the sale of the common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of the common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
The selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended, in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act of 1933, as amended. Each selling stockholder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the common stock.
We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act of 1933, as amended.
Because selling stockholders may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended, they will be subject to the prospectus delivery requirements of the Securities Act of 1933, as amended, including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act of 1933, as amended may be sold under Rule 144 rather than under this prospectus. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling stockholders.
We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares may be resold by the selling stockholders without registration and without the requirement to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144 or (ii) all of the shares have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.
Under applicable rules and regulations under the Securities Exchange Act of 1934, as amended, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act of 1933, as amended).
The validity of the securities being offered by this prospectus been passed upon for us by Sichenzia Ross Friedman Ference LLP, New York, New York.
            Our consolidated financial statements as of December 31, 2014 and 2013 and for the years then ended included in this registration statement have been audited by CohnReznick LLP, an independent registered public accounting firm, as stated in their report, which includes an explanatory paragraph about MabVax Therapeutics Holdings, Inc.’s ability to continue as a going concern have been so included in reliance on the report of such firm, given on the authority of said firm as experts in accounting and auditing.

MABVAX THERAPEUTICS HOLDINGS, INC.
Notes to Unaudited Condensed Consolidated Financial Statements
1. Basis of Presentation
MabVax Therapeutics Holdings, Inc. (f.k.a. Telik, Inc. and referred to herein as “MabVax Therapeutics Holdings” or the “Company”) (OTCQB: MBVX) was incorporated in the state of Delaware on October 20, 1988. On July 8, 2014, Tacoma Acquisition Corp., a Delaware corporation and wholly owned subsidiary of MabVax Therapeutics Holdings (“Tacoma Corp.”) merged with MabVax Therapeutics, Inc., a Delaware corporation (“MabVax Therapeutics”) pursuant to an Agreement and Plan of Merger, dated May 12, 2014, by and among MabVax Therapeutics Holdings, Tacoma Corp. and MabVax Therapeutics, as amended by that certain Amendment No. 1 to the Merger Agreement, dated June 30, 2014, by and among the parties thereto and by that certain Amendment No. 2 to the Merger Agreement, dated July 7, 2014, by and among the parties thereto (such agreement as amended, the “Merger Agreement”; such merger, the “Merger”). Unless the context otherwise requires, references to “we,” “our,” “us,” or the “Company” in this Quarterly Report mean MabVax Therapeutics Holdings on a condensed consolidated financial statement basis with our wholly-owned subsidiary following the Merger, MabVax Therapeutics, as applicable. On October 9, 2014 FINRA approved our stock symbol change request and the Company began trading under the symbol MBVX (OTCQB: MBVX) on October 10, 2014.
The Company is a clinical stage biopharmaceutical company engaged in the discovery, development and commercialization of proprietary human monoclonal antibody products and vaccines for the treatment of a variety of cancers. The Company has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunized against targeted cancers. Therapeutic vaccines under development were discovered at Memorial Sloan Kettering Cancer Center (“MSKCC”), and are exclusively licensed to MabVax Therapeutics. The Company operates in only one business segment.
The Company plans to continue developing MabVax Therapeutics’ pre-Merger pipeline and continue to evaluate the technology and development programs that were under way at MabVax Therapeutics Holdings prior to the Merger.  The Company will terminate unwanted patent applications, and will stop the maintenance fees and patent prosecutions as they come due for the Telintra development program that was in place at MabVax Therapeutics Holdings prior to the Merger.
The Company has incurred net losses since inception and expects to incur substantial losses for the foreseeable future as it continues research and development activities. To date, the Company funded operations primarily through government grants, the sale of preferred stock and equity securities, non-equity payments from collaborators and interest income. The process of developing the Company’s products will require significant additional research and development, preclinical testing and clinical trials, as well as regulatory approval. The Company expects these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. The Company will not receive substantial revenue unless the Company or its collaborative partners complete clinical trials, obtain regulatory approval and successfully commercialize one or more products or the Company licenses its technology after achieving one or more milestones of interest to a potential partner.
The accompanying unaudited condensed consolidated financial statements were prepared using GAAP for interim financial information and the instructions to Regulation S-X. While these statements reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the results of the interim period, they do not include all information or notes required by GAAP for annual financial statements and should be read in conjunction with the Audited Financial Statements of MabVax Therapeutics Holdings for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed on March 31, 2015, as amended on April 2, 2015, and April 30, 2015.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.
The balance sheet data at December 31, 2014, has been derived from audited financial statements at that date. It does not include, however, all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements.
Recent Accounting Pronouncements
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition,” and most industry-specific revenue recognition guidance throughout the Industry Topics of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. In July 2015, the FASB affirmed its proposal to defer the effective date of this standard to annual reporting periods (and interim reporting periods within those years) beginning after December 15, 2017. Entities are permitted to apply the new revenue standard early, but not before the original effective date of annual periods beginning after December 15, 2016. Entities may choose from two adoption methods, with certain practical expedients. The Company is currently reviewing this standard to assess the impact on its future financial statements and evaluating the available adoption methods.
In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation” (Topic 718): “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. ASU No. 2014-12 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, although early adoption is permitted. The Company is currently reviewing this standard to assess the impact on its future financial statements.
In August 2014, the FASB issued ASU No. 2014-15, (“ASU 2014-15”), “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”. ASU 2014-15 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. Management is currently evaluating the impact of the adoption of the updated standard on the financial statements and disclosures.
2. Liquidity and Going Concern
The accompanying condensed consolidated financial statements have been prepared on the going concern basis, which assumes that the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.  As reflected in the accompanying condensed consolidated financial statements, the Company had a net loss of $14,123,107, net cash used in operating activities of $7,917,332, net cash used in investing activities of $68,279, and net cash provided by financing activities of $11,047,148 for the nine months ended September 30, 2015. As of September 30, 2015, the Company had $4,538,680 in cash and cash equivalents and an accumulated deficit of $56,619,570.

On March 31, 2015 and April 10, 2015, the Company closed on a financing transaction by entering into separate subscription agreements with accredited investors relating to the issuance and sale of an aggregate of  $11,714,498 of units (the “Units”) at a purchase price of $0.75 per Unit, with each Unit consisting of one share of the Company’s common stock, par value $0.01 per share  (or, at the election of any Investor who, as a result of receiving common stock would hold in excess of 4.99% of the Company’s issued and outstanding common stock, shares of the Company’s newly designated 0% Series E Convertible Preferred Stock) and a thirty month warrant  to purchase one half of one share of common stock at an initial exercise price of $1.50 per share, as further described in the Notes to Financial Statements – Equity, (the “ April 2015 Private Placement”).
The initial closing of the April 2015 Private Placement took place on March 31, 2015, in which the Company sold an aggregate of $4,995,749 of Units. Following the initial closing the Company entered into separate reconfirmation agreements with the investors in order to extend the initial closing date, increase the offering amount, and adopt a lockup agreement, which was entered by all Investors who elected to continue their investment.  The second closing was completed on April 10, 2015 for an additional $6,718,751 of Units. The Company issued $2,500,000 of Units consisting of Series E Convertible Preferred Stock on April 10, 2015 and the remainder of Units issued in the April 2015 Private Placement were in the form of common stock Units.  Of the total cash received in the second closing on April 10, 2015, $3,500,000 was initially held in escrow under the terms of an escrow agreement with Signature Bank, N.A pending the approval of a representative of one of the lead investors to join the board, or 10 weeks thereafter, unless released sooner or extended.  On June 22, 2015, the Company, Signature Bank, N.A. and OPKO Health, Inc. (“OPKO”) extended the term of the escrow to 16 weeks from the closing of the April 2015 Private Placement.  As further consideration for the amendment, on June 30, 2015, the Company and OPKO entered into a letter agreement pursuant to which the Company granted OPKO the right, but not the obligation, until June 30, 2016, to nominate and appoint up to two additional members of the Company’s board of directors (the “Board” or the “Board of Directors”), or to approve the person(s) nominated by the Company pursuant to the agreement in consideration for the release of the escrowed funds. The nominees will be subject to the satisfaction of standard corporate governance practices and any applicable national securities exchange requirements.  Upon signing the agreement, the escrowed funds were released to the Company.
On October 5, 2015, subsequent to the end of the quarter, the Company closed a public offering of 2,500,000 shares of common stock and warrants to purchase 1,250,000 shares of common stock, at an offering price of $1.10 per share.  For every two shares of common stock sold, the Company issued one warrant to purchase one share of common stock.  The Company received $2,750,000 in gross proceeds, before underwriting discounts and commissions and offering expenses totaling approximately $586,608, and without giving effect to the exercise of the underwriters’ over-allotment option.  The Company granted the underwriters a 30-day option to purchase up to an additional 375,000 shares of common stock and up to an additional 187,500 warrants at the same price to cover over-allotments, if any.  The warrants are immediately exercisable, expire September 30, 2018, and have an exercise price of $1.32 per share.  
The Company anticipates that it will continue to incur net losses into the foreseeable future as it: (i) continues to identify and advance a number of potential drug candidates into clinical and preclinical development activities, (ii) initiates manufacturing of its lead antibody candidate 5B1 and continues to fund its operations, and (iii) expands its corporate infrastructure, including the costs associated with being a public company.  After giving effect to the net proceeds received from the April 2015 Private Placement and the closing of the public offering, management believes that the Company has sufficient funds to meet its obligations through June 2016.
The Company plans to continue to fund its losses from operations and capital funding needs through equity or debt financings, strategic collaborations, licensing arrangements, asset sales, government grants or other arrangements. However, the Company cannot be sure that such additional funds will be available on reasonable terms, or at all. If the Company is unable to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if the Company does not meet its payment obligations to third parties as they come due, it may be subject to litigation claims. Even if the Company is successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. Any of these actions could materially harm the Company’s business, results of operations, and future prospects.
If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business.

3. Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company limits its exposure to credit loss by holding cash in U.S. Dollars or, from time to time, placing cash and investments in U.S. government, agency and government-sponsored enterprise obligations.
4. Fair value of financial instruments
The Company’s financial instruments consist of cash and cash equivalents, grants receivable, prepaid expenses and other current assets and accounts payable, all of which are generally considered to be representative of their respective fair values because of the short-term nature of those instruments.
5. Convertible Preferred Stock, Common Stock and Warrants
Series A-1 preferred stock and common warrants
As of September 30, 2015, and December 31, 2014, there were no shares and 1,593,389 shares of Series A-1 preferred stock outstanding, respectively, and no Series A-1 warrants and 1,280,047 Series A-1 warrants to purchase common stock at $3.62 per share outstanding, respectively.  Both the preferred stock and the warrants had price protection if there were to be a financing at a price lower than their conversion price or exercise price, requiring adjustment as further described in the Company’s Annual Report on Form 10-K.  The Series A-1 preferred stock and warrants were initially structured as Series C-1 preferred stock and common warrants of MabVax Therapeutics prior to the Merger, and were converted from Series C-1 to Series A-1 preferred stock and warrants at the time of the Merger.

Series B Preferred Stock
As of September 30, 2015, and December 31, 2014, there were no shares and 1,250,000 shares of Series B preferred stock and no Series B warrants and 78,125 Series B warrants to purchase common stock at $1.57 a share outstanding, respectively.  Both the preferred stock and the warrants had price protection if there were to be a financing at a price lower than their conversion price or exercise price, requiring adjustment as further described in the Company’s Annual Report on Form 10-K.  As of December 31, 2014, the warrant liability was $92,463.
As a result of the anti-dilution provision contained in the Series B warrants, the Series B warrants were recorded as a current liability in the amount of $92,463 on our consolidated balance sheet as of December 31, 2014.  On March 25, 2015, the Series B warrants were re-valued at $72,656 prior to being exchanged into shares of common stock and Series D convertible preferred stock on a one for one basis and the warrant liability was eliminated and the Company recorded a gain of $19,807 for the three months ended March 31, 2015.
Dividends on Preferred Stock
The Company immediately recognizes the changes in the redemption value on preferred stock as they occur and the carrying value of the security is adjusted to equal what the redemption amount would be as if redemption were to occur at the end of the reporting period based on the conditions that exist as of that date. The value adjustment made to the redemption value and preferred stock dividends for the three and nine months ended September 30, 2015, was an increase of none and $93,234, respectively.
Conversion of Preferred Stock into Common Stock
During the three months ended March 31, 2015, holders of Series A-1, Series B, and Series C preferred stock converted 64,019, 106,437, and 96,571 shares into 38,456, 276,883, and 120,714 shares of common stock, respectively; such conversions eliminated all outstanding Series A-1, Series B, and Series C preferred stock outstanding.

Exchange of Series A-1 and Series B Preferred Stock and Warrants into Common Stock and Series D Preferred Stock
On March 25, 2015, the Company entered into separate exchange agreements with certain holders of the Company’s Series A-1 preferred stock and Merger warrants (the “Series A-1 Exchange Securities”) and holders of the Company’s Series B preferred stock and Series B warrants (the “Series B Exchange Securities” and, collectively with the Series A-1 Exchange Securities, the “Exchange Securities”), all previously issued by the Company. Pursuant to the exchange agreements, the holders exchanged the Exchange Securities and relinquished any and all other rights they may have had pursuant to the Exchange Securities, their respective governing agreements and certificates of designation, including any related registration rights, in exchange for an aggregate of 2,537,502 shares of the Company’s common stock and an aggregate of 238,156 shares of the Company’s newly designated Series D Convertible preferred stock (the “Series D preferred stock”), convertible into 23,815,600 shares of common stock.  No cash was exchanged in the transaction.  The Company recorded deemed dividends of $9,017,512, $8,655,998 and $179,411 representing the excess fair value of the common stock issued over the original conversion terms of the Series A-1 and B preferred stock as part of the consideration for elimination of the Series A-1, Series B convertible preferred stock and Series A-1 warrant, respectively.
Additionally, for as long as a certain principal holder of Exchange Securities holds securities issued pursuant to the exchange agreements, subject to certain exceptions, the Company is restricted from issuing any shares of common stock or securities convertible into common stock, enter into any equity line of credit or issue any floating or variable priced equity linked instrument.
No commission or other payment was received by the Company in connection with the exchange agreements.
Series D Preferred Stock
As of September 30, 2015, there were 191,491 shares of Series D preferred stock issued and outstanding which are convertible into an aggregate of 19,149,100 shares of common stock.
As contemplated by the exchange agreements governing the issuance of the Series D preferred stock and as approved by the Company’s Board of Directors, the Company filed with the Secretary of State of the State of Delaware a Certificate of Designation of Preferences, Rights and Limitations of Series D Convertible Preferred Stock (the “Series D Certificate of Designations”), on March 25, 2015. Pursuant to the Series D Certificate of Designations, the Company designated 1,000,000 shares of its blank check preferred stock as Series D preferred stock. Each share of Series D preferred stock has a stated value of $0.01 per share. In the event of a liquidation, dissolution or winding up of the Company, each share of Series D preferred stock will be entitled to a per share preferential payment equal to the stated value. Each share of Series D preferred stock is convertible into 100 shares of common stock. The conversion ratio is subject to adjustment in the event of stock splits, stock dividends, combination of shares and similar recapitalization transactions. The Company is prohibited from effecting the conversion of the Series D preferred stock to the extent that, as a result of such conversion, the holder beneficially would own more than 4.99% (provided that certain investors elected to block their beneficial ownership initially at 2.49% in the exchange agreements), in the aggregate, of the issued and outstanding shares of the Company’s common stock calculated immediately after giving effect to the issuance of shares of common stock upon the conversion of the Series D preferred stock. Each share of Series D preferred stock entitles the holder to vote on all matters voted on by holders of common stock. With respect to any such vote, each share of Series D preferred stock entitles the holder to cast such number of votes equal to the number of shares of common stock such shares of Series D preferred stock are convertible into at such time, but not in excess of the beneficial ownership limitations.
MabVax Common Stock Financing
On March 31, 2015, the Company consummated the first closing of the April 2015 Private Placement and sold $4,714,726 of Units, net of $281,023 in issuance costs, consisting of 6,661,000 shares of common stock and warrants to purchase 3,330,500 shares of common stock at $1.50 a share.  The Units were sold at a price of $0.75 per Unit.
On April 10, 2015, the Company consummated the second and final closing of the April 2015 Private Placement and sold $3,831,622 of Units, net of $387,127 in issuance costs, of which $2,500,000 of the Units consisted of Series E preferred stock and the balance of i consisting of 5,624,998 shares of common stock, together with warrants to all investors to purchase 4,479,167 shares of common stock at $1.50 a share.  Each Unit was sold at a purchase price of $0.75 per Unit.
The Company paid commissions to broker-dealers in the aggregate amount of approximately $574,000 in the April 2015 Private Placement.

OPKO was the lead investor in the April 2015 Private Placement, purchasing $2,500,000 of Units consisting of Series E preferred stock.
As a condition to OPKO’s participation in the April 2015 Private Placement, each of the other investors in the April 2015 Private Placement agreed to execute lockup agreements restricting the sale of 50% of the securities underlying the Units purchased by them for a period of 6 months and the remaining 50% prior to the expiration of 1 year following the final closing date of the April 2015 Private Placement.

On April 10, 2015, the Company agreed that $3.5 million of the net proceeds of such closing would be paid into and held under and the terms of an escrow agreement with Signature Bank, N.A pending the approval of a representative of OPKO or 10 weeks thereafter, unless released sooner or extended by the Company and OPKO.  On June 22, 2015 the Company and OPKO extended the termination date of the escrow to 16 weeks from the final closing of the April 2015 Private Placement. In connection with the OPKO investment, Steven Rubin, Esq. was appointed advisor to the Company. The escrowed funds were to be returned to the applicable investors and the Company shall have no further obligation to issue Units to such investors in the event certain release conditions are not met. On June 30, 2015 the Company and OPKO entered into a letter agreement pursuant to which the Company granted the representative the right, but not the obligation, until June 30, 2016, to nominate and appoint up to two additional members of the Company’s Board, or to approve the person(s) nominated by the Company pursuant to the agreement in consideration for the release of the escrowed funds. The nominees will be subject to the satisfaction of standard corporate governance practices and any applicable national securities exchange requirements.  Upon signing the agreement, the escrowed funds were released to the Company.
The warrants are exercisable upon issuance and expire 30 months thereafter and may be exercised for cash or on a cashless basis. The warrants have a per share exercise price of $1.50, subject to certain adjustments typical of warrants, namely stock splits, dividends and reverse-splits. The Company is prohibited from effecting the exercise of the warrants to the extent that, as a result of such exercise, the holder beneficially would own more than 4.99% in the aggregate, of the issued and outstanding shares of the Company’s common stock calculated immediately after giving effect to the issuance of shares of common stock upon the exercise of the warrants.
In connection with the Private Placement, the Company also entered into a Registration Rights Agreement with the investors in the Private Placement Pursuant to which the Company has agreed to file a registration statement with the SEC covering resales of up to 25% of common stock issued under the Subscription Agreements and shares issuable upon conversion of the Series E preferred stock, in the event the investors elect to receive Series E preferred stock instead of common stock (together, the “Registrable Securities”), no later than 60 days following the final closing date of the Private Placement, and to use its commercially reasonable best efforts to have such registration statement declared effective with 120 days after filing. The Company will bear all expenses of such registration of the resale of the Registrable Securities.  Investors in the Private Placement also may be required under certain circumstances to agree to refrain from resales of a percentage of their securities upon request of an underwriter or placement agent in a future offering. The liquidated damages for failure to achieve effectiveness of the Registerable Securities is 1% a month 120 days after filing, and provided management has not used commercially reasonable best efforts to have the registration statement declared effective within that timeframe.

In connection with the April 2015 Private Placement, the Company also entered into a registration rights agreements (the “Registration Rights Agreements”) with the investors in the April 2015 Private Placement Pursuant to which the Company has agreed to file a registration statement with the SEC covering resales of up to 25% of common stock issued under the Subscription Agreements and shares issuable upon conversion of the Series E preferred stock, in the event the investors elect to receive Series E preferred stock instead of common stock (together, the “Registrable Securities”), no later than 60 days following the final closing date of the April 2015 Private Placement, and to use its commercially reasonable best efforts to have such registration statement declared effective with 120 days after filing. The Company will bear all expenses of such registration of the resale of the Registrable Securities.  Investors in the Private Placement also may be required under certain circumstances to agree to refrain from resales of a percentage of their securities upon request of an underwriter or placement agent in a future offering. The liquidated damages for failure to achieve effectiveness of the Registerable Securities is 1% a month 120 days after filing, and provided management has not used commercially reasonable best efforts to have the registration statement declared effective within that timeframe.
On June 9, 2015 the Company and investors holding over 60% of the outstanding Registrable Securities (as such term is defined in the Registration Rights Agreements) entered into an amendment agreement to the Registration Rights Agreements in order to: (i) amend the definition of “Filing Date” for the initial registration statement such that such term shall be defined as “August 5, 2015” and (ii) waive any payments that may be due to the Investors as a result of the Company not filing a registration statement on or before the Filing Date, as such term was originally defined.  On August 4, 2015, the Company and Investors holding over 70% of the outstanding Registrable Securities entered into a second amendment agreement to further extend the Filing Date to October 9, 2015.

On October 12, 2015, the Company and Investors holding over 60% of the outstanding Registerable Securities (as such term is defined in the Registration Rights Agreements) entered into a third amendment agreement to the Registration Rights Agreements to suspend the Company’s registration obligations under the Registration Rights Agreements and related subscription agreements during any period when the “Standstill” provision set forth in 5(u) of the subscription agreements is in effect. 

Except for certain issuances, for a period beginning on the closing date of the April 2015 Private Placement and ending on the date that is the earlier of (i) 24 months from the final closing date of the April 2015 Private Placement, (ii) the date the Company consummates a financing (excluding proceeds from the April 2015 Private Placement) in which the Company receives gross proceeds of at least $10,000,000 and (iii) the date the common stock is listed for trading on a national securities exchange (such period until the earlier date, the “Price Protection Period”), in the event that the Company issues any shares of common stock or securities convertible into common stock at a price per share or conversion price or exercise price per share that is less than $0.75, the Company shall issue to the investors in the April 2015 Private Placement such additional number of shares of common stock such that the investor shall own an aggregate total number of shares of common stock as if they had purchased the Units at the price of the lower price issuance.

The underwriter will receive no fee or underwriting discount with respect to sales to certain existing investors unless such existing investors participate in the offering in the aggregate minimum amount of $2,000,000, in which case the underwriter will receive a flat fee of $100,000 in lieu of any underwriting discount for sales made to such existing investors.
3.
The presentation in this table assumes the purchase of securities by certain existing investors who have indicated an interest in purchasing an aggregate of up to approximately $3.15 million in securities in this offering at the offering price. However, because indications of interest are not binding agreements or commitments to purchase, this investor may determine to purchase fewer securities than they had indicated an interest in purchasing or not to purchase any securities in this offering.

We have agreed to reimburse Laidlaw & Company (UK) Ltd., for certain out-of-pocket expenses (including the reasonable fees and disbursements of counsel to the underwriter) not to exceed $80,000, upon the successful completion of this offering, without our prior written consent, such consent not to be unreasonably withheld.  We estimate that expenses payable by us in connection with this offering, including reimbursement of Laidlaw & Company (UK) Ltd.’s expenses but excluding the underwriting discount referred to above, will be approximately $490,000.
Indemnification
We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or the Securities Act, and liabilities arising from breaches of representations and warranties contained in the underwriting agreement, or to contribute to payments that the underwriter may be required to make in respect of those liabilities.
Lock-up Agreements
We, our officers and our directors have agreed, subject to limited exceptions, for a period of 90 days after the date of the underwriting agreement, not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of, directly or indirectly any shares of common stock or any securities convertible into or exchangeable for our common stock either owned as of the date of the underwriting agreement or thereafter acquired without the prior written consent of Laidlaw & Company (UK) Ltd.  Laidlaw & Company (UK) Ltd. may, in its sole discretion and at any time or from time to time before the termination of the lock-up period, without notice, release all or any portion of the securities subject to lock-up agreements.
Price Stabilization, Short Positions and Penalty Bids
In connection with the offering the underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act:
Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.
Over-allotment involves sales by the underwriter of securities in excess of the number of securities the underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of securities over-allotted by the underwriter are not greater than the number of securities that they may purchase in the over-allotment option. In a naked short position, the number of securities involved is greater than the number of securities in the over-allotment option. The underwriter may close out any covered short position by either exercising its over-allotment option and/or purchasing securities in the open market.
Syndicate covering transactions involve purchases of securities in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of securities to close out the short position, the underwriter will consider, among other things, the price of securities available for purchase in the open market as compared to the price at which it may purchase securities through the over-allotment option. If the underwriter sells more securities than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying securities in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.
Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the common stock originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.


These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market prices of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of our common stock may be higher than the prices that might otherwise exist in the open market. Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the prices of our common stock. In addition, neither we nor the underwriter make any representations that the underwriter will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.
Listing and Transfer Agent
Our common stock is quoted on The NASDAQ Capital Market under the symbol “MBVX.” The transfer agent of our common stock is Computershare Trust Company, N.A.

From time to time, the underwriter and/or its affiliates may have provided, and may in the future provide, various investment banking and other financial services for us for which services it may have received and, may in the future receive, customary fees.  In the course of its business, the underwriter and its affiliates may actively trade our securities or loans for their own account or for the accounts of customers, and, accordingly, the underwriter and its affiliates may at any time hold long or short positions in such securities or loans.  Except for services provided in connection with this offering, the underwriter has not provided any investment banking or other financial services to us during the 180-day period preceding the date of this prospectus and we do not expect to retain the underwriter to perform any investment banking or other financial services for at least 90 days after the date of this prospectus.

The Company provided antibody material to Rockefeller University, which is exploring the mechanism of action of constant region (Fc) variants of the HuMab 5B1 in the role of tumor clearance. The Company will supply additional research materials as requested by the university, which is evaluating ways to optimize the function.
 
Juno Therapeutics Option Agreement
On August 29, 2014, MabVax Therapeutics entered into an Option Agreement (the “Option Agreement”) with Juno Therapeutics, Inc. (“Juno”). Pursuant to the Option Agreement, MabVax Therapeutics granted Juno the option to obtain an exclusive, world-wide, royalty-bearing license authorizing Juno to develop, make, have made, use, import, have imported, sell, have sold, offer for sale and otherwise exploit certain patents MabVax Therapeutics developed with respect to fully human antibodies with binding specificity against human GD2 or sialyl-Lewis A antigens and certain MabVax Therapeutics controlled biologic materials. Juno may exercise its option to purchase the license until the earlier of June 30, 2016 or 90 days from the date MSKCC completes its research with respect to the patents in accordance with the terms of agreements by and between MSKCC and MabVax Therapeutics.
During the three and nine months ended September 30, 2015, no revenues had been earned under the Option Agreement, however the Option Agreement remains valid and active.
The Option Agreement may be terminated by either party (i) upon material breach of the other party if the breach is not cured within 30 days, or (ii) with 60 days’ prior written notice in the event the other party becomes the subject of a voluntary or involuntary petition in bankruptcy. Juno may terminate the Option Agreement at any time upon 30 days’ prior written notice. MabVax Therapeutics may terminate the Option Agreement if Juno, or any Juno employee or affiliate, is a party to any action or proceeding in which Juno, or any Juno employee or affiliate, opposes the patents or otherwise seeks a determination that any of the patents are invalid or unenforceable if Juno, or as applicable, its employee and/or affiliate, fails to discontinue its involvement in such an action within 10 days of receiving notice from MabVax Therapeutics.

As consideration for the grant of the exclusive option to purchase the license, Juno paid MabVax Therapeutics a one-time up-front option fee in the low five figures. Should the option be exercised, MabVax Therapeutics would expect to negotiate with Juno to pay amounts that include MabVax Therapeutics license fees, milestone payments, and royalty-based compensation in connection with entering into a License. The terms of the license including the financial terms are expected to be agreed upon at a future date.

9. Commitments and contingencies
Litigation
On May 30, 2014, a class action lawsuit was commenced in Santa Clara County Superior Court, State of California, on behalf of Cadillac Partners and others similarly situated, naming as defendants, MabVax Therapeutics, the Company and the Company’s directors, Hudson Bay Capital Management LP, Bio IP Ventures LLC, Hudson Bay Master Fund Ltd., and Hudson Bay IP Opportunities Master Fund LP, together the “Parties”. The suit alleged the defendants breached certain fiduciary duties, or aided and abetted a breach of fiduciary duties, in connection with the Company’s Merger with MabVax Therapeutics. In support of their purported claims, the plaintiff alleged, among other things, that the Company’s board has historically failed to fulfill its fiduciary duty to its stockholders, and claiming with respect to the Series B Private Placement and the Merger, that such transactions involved an inadequate sales process and included preclusive deal protection devices, and that the Company’s board of directors would receive personal benefits not available to its public stockholders as a result of the Merger. The plaintiff sought to enjoin the Merger and obtain damages as well as attorneys’ and expert fees and costs.
On June 29, 2014, the parties entered into a Stipulation and Settlement (the “Settlement”), pursuant to which the Company agreed to file with the SEC certain supplemental disclosures in connection with the Merger. The Settlement was subject to certain confirmatory discovery to be undertaken by the plaintiff and to the Parties’ agreement on the payment of the plaintiff’s attorneys’ fees and expenses.
On July 16, 2014, the Company and all other parties to the litigation entered into an agreement which, if consummated, would settle the litigation (the “Proposed Settlement”). Among many other terms, under the Proposed Settlement the Company and all defendants will receive a broad release of any and all claims pertaining to the Series B Private Placement, the Merger, the prior disclosure and a wide variety of other matters. The Proposed Settlement also calls for the parties to ask the court to, among other things, enter orders enjoining other stockholders from bringing similar actions, certifying the putative settlement class, and approving the Proposed Settlement as a fair, final, and binding resolution of the litigation. Under the Proposed Settlement, the Company and the other defendants have expressly denied the allegations of the complaint and denied engaging in any other misconduct, nor will any of them make any payment or in any respect amend the negotiated terms of the since-consummated Series B Private Placement and Merger. Finally, under the Proposed Settlement, the Company and the other defendants have not agreed to pay any legal fees, or reimburse any expenses, allegedly incurred by the plaintiffs who filed the complaint; instead, the Company expects that counsel for those plaintiffs will present any such disputed claim for legal fees and expenses to the court for resolution.
On April 20, 2015, the Parties made an application for an Order for Notice and Scheduling of Hearing of Settlement in accordance with a Stipulation of Settlement dated as of April 20, 2015 (the “Action”), which sets forth the terms and conditions for settlement and which provides for dismissal of the Action with prejudice.  The Order after Hearing on June 12, 2015, provided preliminary approval of the settlement that was agreed to by the Parties, in which the Company provided supplemental disclosures in the definitive proxy filed with the SEC on June 30, 2014.  Notice of the action as a class action was sent to class members in July 2015.

On September 18, 2015, an Order and Final Judgement was entered by the Superior Court of the State of California, approving the settlement that was agreed upon by both parties and closing the case.  The Company anticipates that there will be no additional future expenses incurred in this action by the Company after the September 30, 2015 balance sheet date which would not be offset by insurance.
Operating Leases
In connection with the Merger, the Company recorded a $590,504 contingent lease termination fee, in connection with the termination by MabVax Therapeutics Holdings (f.k.a. Telik, Inc.) of the master lease and sublease of the Porter Drive Facility, which is payable to ARE-San Francisco No. 24 (“ARE”), if the Company receives $15 million or more in additional financing in the aggregate, but otherwise forgiven.

On September 2, 2015, the Company entered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises consisting of a total of approximately 14,971 square feet of office and laboratory space in buildings located at 11535-11585 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”).  Due to the fact that certain tenant improvements need to be made to the New Premises before the Company can occupy the New Premises, the term of the Lease will commence when the New Premises are ready for occupancy, currently estimated to be approximately November 1, 2015.  The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the monthly base rent will be $35,631, subject to annual increases as set forth in the Lease.

The Company has an option to extend the Lease term for a single, five-year period.  If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value.  In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued in connection with the ownership and operation of the property.
10. Subsequent Events
On October 5, 2015, the Company closed a public offering of 2,500,000 shares of common stock and warrants to purchase 1,250,000 shares of common stock, at an offering price of $1.10 per share.  For every two shares of common stock sold, the Company issued one warrant to purchase one share of common stock.  The Company received $2,750,000 in gross proceeds, before underwriting discounts and commissions and offering expenses totaling approximately $586,608, and without giving effect to the exercise of the underwriters’ over-allotment option.  Such costs were recorded as deferred costs on the Company’s balance sheet as of September 30, 2015, and were deducted or paid from the gross proceeds from the transaction. The Company intends to use the net proceeds from this offering to fund the HuMab 5B1 human antibody program through Phase I clinical development and for working capital and general corporate purposes.

The Company granted the underwriters a 30-day option to purchase up to an additional 375,000 shares of common stock and up to an additional 187,500 warrants at the same price to cover over-allotments, if any.  The shares and warrants were separately issued and sold in equal proportions. The warrants are immediately exercisable, expire September 30, 2018, and have an exercise price of $1.32 per share.  The warrants will not be listed on any securities exchange or other trading market.

Under the terms of the underwriting agreement entered into between the Company and the underwriter in the public offering, the Company, without the prior written consent of the underwriter, is prohibited, for a period of 90 days after execution of the underwriting agreement, from issuing any equity securities, subject to certain exceptions.
On October 12, 2015, the Company and investors holding over 60% of the outstanding Registerable Securities (as such term is defined in the Registration Rights Agreements) issued in the April 2015 Private Placement entered into a third amendment agreement to the Registration Rights Agreements to suspend the Company’s registration obligations under the Registration Rights Agreements and related subscription agreements during any period when the “Standstill” provision set forth in 5(u) of the related subscription agreements is in effect.


 
To the Board of Directors and Stockholders
MabVax Therapeutics Holdings, Inc.
 
We have audited the accompanying consolidated balance sheets of MabVax Therapeutics Holdings, Inc. (the “Company”) as of December 31, 20142016 and 2013,2015, and the related consolidated statements of operations, redeemable convertible preferred stock, convertible preferred stock and stockholders’ equity, (deficit), and cash flows for the years then ended. MabVax Therapeutics Holdings, Inc.’s management is responsible for these consolidated financial statements. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of MabVax Therapeutics Holdings, Inc. as of December 31, 20142016 and 2013,2015, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.
 
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred recurring operating losses and is dependent on additional financing to fund operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are described in Note 1 to the consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

1. Nature of Operations and Basis of Presentation
 
MabVax Therapeutics Holdings, Inc. (f.k.a. Telik, Inc. and referred to herein as “MabVax Therapeutics Holdings” or the “Company”) (OTCQB:(NASDAQ: MBVX) was incorporated in the state of Delaware on October 20, 1988. On July 8, 2014, Tacoma Acquisition Corp., a Delaware corporation and wholly owned subsidiary of MabVax Therapeutics Holdings (“Tacoma Corp.”) merged with MabVax Therapeutics, Inc., a Delaware corporation (“MabVax Therapeutics”) pursuant to an Agreement and Plan of Merger, dated May 12, 2014, by and among MabVax Therapeutics Holdings, Tacoma Corp. and MabVax Therapeutics, as amended by that certain Amendment No. 1 to the Merger Agreement, dated June 30, 2014, by and among the parties thereto and by that certain Amendment No. 2 to the Merger Agreement, dated July 7, 2014, by and among the parties thereto (such agreement as amended, the “Merger Agreement”; such Merger, the “Merger”). Unless the context otherwise requires, references to “we,” “our,” “us,” or the “Company” in this Annual Report mean MabVax Therapeutics Holdings, Inc. on a consolidated financial statement basis with our wholly-ownedwholly owned subsidiary following the Merger, MabVax Therapeutics, as applicable. On October 9, 2014, the Financial Industry Regulatory Authority (FINRA) approved the Company’s stock symbol change request and the Company began trading on the OTCQB under the symbol MBVX on October 10, 2014. On August 17, 2016, our common stock began trading on The NASDAQ Capital Market under the symbol “MBVX.”
 
ParOn August 16, 2016, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware in order to effectuate a reverse stock split of our issued and outstanding common stock on a 1 for 7.4 basis, effective on August 16, 2016 (the “Reverse Stock Split”). The Reverse Stock Split was effective with FINRA and the Company’s common stock began trading on The NASDAQ Capital Market at the open of business on August 17, 2016. All share and per share amounts, and number of shares of common stock into which each share of preferred stock will convert, in the financial statements and notes hereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in par value andof common stock to additional paid-in capital for December 31, 2013 has been restated to reflect the par value for shares post-merger and the September 8, 2014, 8-for-1 Reverse Split (as defined in note 5).capital.
 
We areThe Company is a clinical stage biopharmaceutical company engaged in the discovery, development and commercialization of proprietary human monoclonal antibody products and vaccines for the treatment of a variety of cancers. We haveThe Company has discovered a pipeline of human monoclonal antibody products based on the protective immune responses generated by patients who have been immunized against targeted cancers. Therapeutic vaccines under development were discovered at Memorial Sloan Kettering Cancer Center (“MSK”), and are exclusively licensed to MabVax Therapeutics. We operateThe Company operates in only one business segment.
 
We are continuing to evaluate the technology and development programs that were under way at theThe Company prior to the Merger and plan to continue developing MabVax Therapeutics’ pre-Merger pipeline.
We havehas incurred net losses since inception and expectexpects to incur substantial losses for the foreseeable future as the Companyit continues its research and development activities. To date, we havethe Company has funded operations primarily through government grants, the sale of preferred stock and equity securities, debt financing, non-equity payments from collaborators and interest income. The process of developing the Company’s products will require significant additional research and development, preclinical testing and clinical trials, as well as regulatory approval. We expectapprovals. The Company expects these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. WeThe Company will not receive substantial revenue unless the Company or its collaborative partners complete clinical trials, obtain regulatory approvalapprovals and successfully commercialize one or more products; or the Company licenses its technology after achieving one or more milestones of interest to a potential partner.
 
The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.
Liquidity and Going Concern
 
The accompanying consolidated financial statements have been prepared on the going concern basis, which assumes that the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. As reflected in the accompanying consolidated financial statements, the Company had a net loss of $7,917,853,$17,660,483, net cash used in operating activities of $7,662,019$12,363,411 and net cash provided byused in investing activities of $1,452,476,$563,196 for the year ended December 31, 2014.2016. As of December 31, 2014,2016, the Company had $1,477,143$3,979,290 in cash and cash equivalents and an accumulated deficit of $24,550,308.$78,262,261.
 

From February 13, 2014 through July 7, 2014, MabVax Therapeutics Holdings completedOn January 15, 2016, the Company and Oxford Finance LLC, as collateral agent and lender, entered into a seriesloan and security agreement (the “Loan Agreement”) providing for senior secured term loans to the Company in an aggregate principal amount of financing transactions totaling approximately $7.3 million netup to $10,000,000, subject to the terms and conditions set forth in the Loan Agreement (the “January 2016 Term Loan”).  On January 15, 2016, the Company received an initial loan of $5,000,000 under the Loan Agreement, before fees and issuance costs of approximately $300,000 in issuance costs, through the sale$390,000.
On August 22, 2016, we closed a public offering of MabVax Therapeutics Holdings preferred stock, MabVax Therapeutics Holdings1,297,038 shares of common stock and exercise665,281 shares of MabVax Therapeutics Holdings warrants.Series F Preferred Stock, and warrants to purchase 1,962,319 shares of common stock at $5.55 per share and warrants to purchase 1,962,319 shares of common stock at $6.29 per share, at an offering price of $4.81 per share (the “August 2016 Public Offering”).  For every one share of common stock or Series F Preferred Stock sold, we issued one warrant to purchase one share of common stock at $5.55 per share and one warrant to purchase one share of common stock at $6.29 per share.  We received $9,438,753 in gross proceeds, before underwriting discounts and commissions and offering expenses totaling $871,305. The gross proceeds include the underwriters’ over-allotment option, which they exercised on the closing date.
 
TheWe anticipate that the Company anticipates that it will continue to incur net losses into the foreseeable future as it:we: (i) continues to identifycontinue our Phase I clinical trial for our standalone therapeutic HuMab 5b-1, designated as MVT-5873 that was initiated in the first quarter of 2016; (ii) continue our Positron Emission Tomography (“PET”) imaging agent 89Zr-HuMab-5B1, designated as MVT-2163 that was initiated in July 2016; (iii) initiate our clinical trial for the development of our HuMab-based radioimmunotherapy product, designated as MVT-1075; (iv) continue preclinical work on several other programs; and advance a number of potential drug candidates into clinical and preclinical development activities, (ii) initiates manufacturing of its lead antibody candidate 5B1 and continues to fund its(iv) continue operations and (iii) expands its corporate infrastructure, including the costs associated with beingas a public company. Without additional funding, managementManagement believes that the Company will not havehas sufficient funds to meet its obligations beyond October 2015, unless the Company is able to raise additional capital.through April 2017. These conditions give rise to substantial doubt as to the Company’s ability to continue as a going concern. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
 
The Company plansWe plan to continue to fund itsthe Company’s losses from operations and capital funding needs through equity or debt financings, strategic collaborations, licensing arrangements, asset sales, government grants or other arrangements. However, the Companywe cannot be sure that such additional funds will be available on reasonable terms, or at all. If the Company iswe are unable to secure adequate additional funding, the Companywe may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. In addition, if the Company does not meet its payment obligations to third parties as they come due, it may be subject to litigation claims. Even if the Company iswe are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management. Any of these actions could materially harm the Company’s business, results of operations, and future prospects.
 
If the Company raises additional funds by issuing equity securities, substantial dilution to existing stockholders would result. If the Company raises additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations as well as covenants and specific financial ratios that may restrict the Company’s ability to operate its business.
 
2. Summary of Significant Accounting Policies
 
Basis of Presentation
 
The accompanying consolidated financial statements reflect all of our activities, including those of our wholly owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.
 
Use of Estimates
 
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Management believes that these estimates are reasonable; however, actual results may differ from these estimates.
 
Cash and Cash Equivalents
 
   The Company considersWe consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The Company minimizes its credit risk associated with cash and cash equivalents by periodically evaluating the credit quality of its primary financial institution. The balance at times may exceed Federallyfederally insured limits. As of December 31, 2016, cash and cash equivalents exceeded federally insured limits by approximately $3.7 million. The Company has not experienced any losses on such accounts.

 
Fair Value of Financial Instruments
 
The Company’s financial instruments consist of cash and cash equivalents, grants receivable, other receivable, prepaid expenses and other assets, accounts payable, related party payables and warrant liabilities, all of which are generally considered to be representative of their respective fair values because of the short-term nature of those instruments.
 
Grants Receivable
 
Grants receivable at December 31, 2014 represent2015 represented amounts due under the NIH Imaging Contract Phase II with the National Cancer Institute (the “NCI”), a division of the National Institutes of Health, or NIH (collectively, the “NIH Grants”). The Company considers the grants receivable to be fully collectible; accordingly, no allowance for doubtful accounts has been established. Grants receivable balances may include unbilled amounts for which work was completed by the Company as of the balance sheet date. If amounts become uncollectible, they are charged to operations. There were no grant receivable amounts outstanding as of December 31, 2016.
 
Property and Equipment
 
Property and equipment are carried at cost less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets, which are generally three to fiveseven years. Leasehold improvements are amortized over the lesser of the life of the lease or the life of the asset.

Impairment of Long-lived Assets
 
   The Company evaluates itsWe evaluate the Company’s long-lived assets with definite lives, such as property and equipment, for impairment. The Company recordsWe record impairment losses on long-lived assets used for operations when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the carrying value of the assets. There have not been any impairment losses of long-lived assets for the years ended December 31, 20142016 and 2013.2015.
 
Impairment of Goodwill
 
The Company applies the GAAP principles related to Intangibles – Goodwill and Other related to performing a test for goodwill impairment annually. DuringFor the fourth quarter, there was a triggering event that occurred as a result of the decline in the Company’s market capitalization. As a result,years ended December 31, 2016 and 2015, the Company went toperformed a step 1 analysis utilizingand assessed the market value of the Company to determine whether an external valuation firm to value the Company.impairment had taken place. Based upon the analysis performed no impairment was noted, therefore performing step 2 was not required. The Company has concluded that no impairment of Goodwill has taken place for the yearyears ended December 31, 2014.2016 and 2015. Further, in performing a qualitative assessment, the Company concluded no events and circumstances have taken place that would have indicated that an impairment had taken place. 
 
Revenue Recognition
 
Revenue from grants areis based upon internal and subcontractor costs incurred that are specifically covered by the grant, including a facilities and administrative rate that provides funding for overhead expenses. NIH Grants are recognized when the Company incurs internal expenses that are specifically related to each grant, in clinical trials at the clinical trial sites, by subcontractors who manage the clinical trials, and provided the grant has been approved for payment. U.S. Treasury grant awards are based upon internal research and development costs incurred that are specifically covered by the grant, and revenues are recognized when the Company incurs internal expenses that are related to the approved grant. The Company records revenue associated with the NIH Grants as the related costs and expenses are incurred. Any amounts received by the Company pursuant to the NIH Grants prior to satisfying the Company’s revenue recognition criteria are recorded as deferred revenue.

 
Research and Development Costs
 
Research and development expenses, which consist primarily of salaries and other personnel costs, clinical trial costs and preclinical study fees, manufacturing costs for non-commercial products, and the development of earlier-stage programs and technologies, are expensed as incurred when these expenditures have no alternative future uses. A significant portion of the development activities are outsourced to third parties, including contract research organizations. In such cases, the Company may be required to estimate related service fees incurred.
 
Stock-based Compensation
 
The Company’s stock-based compensation programs include grants of common stock and stock options to employees, non-employee directors and non-employee consultants. Stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense, under the straight-line method, over the employee’s requisite service period (generally the vesting period of the equity grant).
 
The Company accounts for equity instruments, including common stock and stock options, issued to non-employees in accordance with authoritative guidance for equity based payments to non-employees. Stock options issued to non-employees are accounted for at their estimated fair value determined using the Black ScholesBlack-Scholes-Merton option-pricing model. The fair value of options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered.
 
Income Taxes
 
The Company uses the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to basis differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. As of December 31, 20142016 and 2013,2015, all deferred tax assets were fully offset by a valuation allowance.
 
The Company accrues interest and penalties, if any, on underpayment of income taxes related to unrecognized tax benefits as a component of income tax expense in its consolidated statements of operations.
 
Fair Value Measurements
 
Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate.
 

3. Recent Accounting Pronouncements
The Company has historically reported as a development stage company. In the period ended June 30, 2014, the Company elected to early adopt FASB Accounting Standards Update (“ASU”) No. 2014-10, “Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements.” The adoption of this ASU allows the Company to remove the inception to date information and all references to development stage.
 
In May 2014,November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes. Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified balance sheet. The new standard simplifies the presentation of deferred tax assets and liabilities and requires that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. This ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, with early adoption permitted. This ASU affected our disclosures relating to deferred tax assets and liabilities. The Company has applied this guidance prospectively and it did not have a material impact on the consolidated balance sheets.

In February 2016, the FASB issued ASU 2016-2,"Leases (Topic 842)."  This update will increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.  Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged, and it simplified the accounting for sale and leaseback transactions. Lessees will no longer be provided with a source of off-balance sheet financing. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently in the process of assessing what impact this new standard may have on our consolidated financial statements.
In March 2016, the FASB issued ASU 2016-09, “Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This update includes multiple provisions intended to simplify various aspects of the accounting for share-based payment transactions including accounting for excess tax benefits and tax deficiencies, classification of excess tax benefits in the statement of cash flows and accounting for award forfeitures. This update is effective for annual and interim reporting periods of public entities beginning after December 15, 2016, with early adoption permitted. We do not expect the adoption of this new standard to have a material impact on our consolidated financial statements.
In August 2016, the FASB issued ASU No. 2014-09, “Revenue2016-15 (“ASU 2016-15”), “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The standard provides guidance on eight (8) cash flow issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon bonds; (3) contingent consideration payments after a business combination; (4) proceeds from Contracts with Customers” (Topic 606). ASU No. 2014-09 supersedes the revenue recognition requirementssettlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in Topic 605, “Revenue Recognition,”securitization transactions; and most industry-specific revenue recognition guidance throughout the Industry Topics(8) separately identifiable cash flows and application of the Accounting Standards Codification. Additionally, this update supersedes some cost guidance includedpredominance principle. ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The core principlethe statement of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Itcash flows. ASU 2016-15 is effective for the firstfiscal years, and interim periodperiods within annual reporting periodsthose years, beginning after December 15, 2016, and2017 with early adoption ispermitted. The adoption of this new standard did not permitted. Entities may choose from two adoption methods, with certain practical expedients. We are currently reviewing this standard to assess thehave a material impact on the Company’s future financial statements and evaluating the available adoption methods.
In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation” (Topic 718): “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. ASU No. 2014-12 is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, although early adoption is permitted. We are currently reviewing this standard to assess the impact on the Company’s futureour consolidated financial statements.
 
In August 2014, the FASB issued ASU No. 2014-15 (“("ASU 2014-15”2014-15"), “Disclosure of Uncertainties Aboutabout an Entity’s Ability to Continue as a Going Concern”. ASU 2014-15 requires management to perform interim and annual assessments of an entity’sConcern.” This standard provides guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern.provide related footnote disclosures. ASU No. 2014-15 applies to all entities and is effective for annual and interim reporting periodsfiscal years ending after December 15, 2016 and for interim and annual periods therein with early adoption permitted. Management is currently evaluating the impact of the The adoption of the updatedthis new standard did not have a material impact on theour consolidated financial statements and disclosures.statements.
 
Management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying consolidated financial statements.

5. Reverse Stock Split Name Change and Increase in Authorized Shares
 
On September 8, 2014, MabVax Therapeutics Holdings filed an amended and restated certificate of incorporation to increase the authorized number of shares of our common stock to a new total of 150,000,000 shares, increase the number of shares of our preferred stock to a new total of 15,000,000 shares, and change the name of the Company from “Telik, Inc.” to “MabVax Therapeutics Holdings, Inc.” The amendment and restatement of the certificate of incorporation effectuating the name change and above authorized share increases were approved by our stockholders at the special stockholder meeting on September 8, 2014 and by our Board of Directors at a meeting of the Board held on September 8, 2014.
On September 8, 2014, following the filing of the amended and restated certificate disclosed above, MabVax Therapeutics HoldingsAugust 16, 2016, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation with the amended and restated certificateSecretary of incorporationState of the State of Delaware in order to effect an 8-for-1effectuate a reverse stock split onof our issued and outstanding common stock on a 1 for 7.4 basis, effective on August 16, 2016 (the “Reverse Stock Split”), effective as of 4:01 p.m. Eastern Time (the “Effective Time”) on September 8, 2014 (the “Effective Date”). The Reverse Stock Split was approved by our stockholders ateffective with FINRA and the special stockholder meeting held on September 8, 2014 and by the Board of Directors at a meeting of the Board held on September 8, 2014.
On the Effective Date, immediately and without further action by our stockholders, every 8 shares of our common stock, issued and outstanding immediately prior to the Effective Time, were automatically converted into 1 share of our common stock. As a result of the Reverse Split and calculated as of the Record Date, the number of outstanding shares of our common stock was reduced from 13,932,937 to 1,741,617, excluding outstanding and unexercised share options and warrants and subject to adjustment for fractional shares. No fractional shares were issued as a result of the Reverse Split and, in lieu of these fractional shares, any holder of less than 1 share of our common stock was entitled to receive cash for such holder’s fractional share equal to the product of such fraction multiplied by the average of the last reported bid and ask prices of our common stock at 4:00 p.m., Eastern time, end of regular trading hours on OTCQB marketplace, during the 10 consecutive trading days ending on the last trading day prior to the Effective Date. Further, any options, warrants and contractual rights outstanding as of the Effective Date that were subject to adjustment were adjusted in accordance with their terms. These adjustments included, without limitation, changes to the number of shares of our common stock that may be obtained upon exercise or conversion of these securities, and changes to the applicable exercise or purchase price of such securities.
Shares of our common stock began to trade on the OTCQB marketplace on a post-split basis under the name MabVax Therapeutics Holdings, Inc. on September 10, 2014 under the new CUSIP number 55414P108. MabVax Therapeutics Holdings retained the same CUSIP number when itsCompany’s common stock began trading on The NASDAQ Capital Market at the OTCQB marketplace underopen of business on August 17, 2016. All share and per share amounts, and number of shares of common stock into which each share of preferred stock will convert, in the trading symbol MBVXfinancial statements and notes hereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in par value of common stock to additional paid-in capital.
6. Notes Payable, Net
On January 15, 2016, we entered into a loan and security agreement with Oxford Finance LLC pursuant to which we had the option to borrow $10,000,000 in two equal tranches of $5,000,000 each (the “Loan Agreement”).  The first tranche of $5,000,000 was funded at close on October 10, 2014.January 15, 2016 (the “Term A Loan”). The option to fund the second tranche of $5,000,000 (the “Term B Loan”) was upon the Company achieving positive interim data on the Phase 1 HuMab-5B1 antibody trial in pancreatic cancer and successfully uplisting to either the NASDAQ Capital Market or NYSE MKT on or before September 30, 2016.  The option for the Term B Loan expired on September 30, 2016. The Company is not pursuing completion of any additional debt financing with Oxford Finance LLC at the present time. The interest rate for the Term A Loan is set on a monthly basis at a rate equal to the greater of: the index rate plus 11.29%, where the index rate is the 30-day LIBOR rate; or 11.5%. Interest is due on the first day of each month, in arrears, calculated based on a 360-day year.  The loan is interest only for the first year after funding, and the principal amount of the loan is amortized in equal principal payments, plus period interest, over the next 36 months.  A facility fee of 1.0% or $100,000 was due at closing of the transaction, and was incurred and paid by the Company on January 15, 2016.  The Company is obligated to pay a $150,000 final payment upon completion of the term of the loan, and this amount is being accreted using the effective interest rate method over the term of the loan. The amount being accreted is included in the long-term portion of notes payable, net, on the balance sheet Each of the term loans can be prepaid subject to a graduated prepayment fee, depending on the timing of the prepayment.

Concurrent with the closing of the transaction, the Company issued 225,226 common stock purchase warrants to Oxford Finance LLC with an exercise price of $5.55 per share.  The warrants are exercisable for five years and may be exercised on a cashless basis, and expire on January 15, 2021. The Company recorded $607,338 for the fair value of the warrants as a debt discount within notes payable and an increase to additional paid-in capital on the Company’s balance sheet. We used the Black-Scholes-Merton valuation method to calculate the value of the warrants. The debt discount is being amortized as interest expense over the term of the loan using the effective interest method.
We granted Oxford Finance LLC a perfected first priority lien on all of the Company’s assets with a negative pledge on intellectual property. The Company paid Oxford Finance LLC a good faith deposit of $50,000, which was applied towards the facility fee at closing.  The Company agreed to pay all costs, fees and expenses incurred by Oxford Finance LLC in the initiation and administration of the facilities including the cost of loan documentation.
At the initial funding, the Company received net proceeds of approximately $4,610,000 after fees and expenses. These fees and expenses are being accounted for as a debt discount and classified within notes payable on the Company’s consolidated balance sheet as a direct deduction from the carrying amount of the notes payable, consistent with debt discounts. Debt discounts, issuance costs and the final payment are being amortized or accreted as interest expense over the term of the loan using the effective interest method.


 
All prior periods in these consolidated financial statements have been adjustedThe Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, our failure to reflect the effectsfulfill certain of the Merger andCompany's obligations under the Reverse Split, unless otherwise indicated.Loan Agreement, the occurrence of a material adverse change, which is defined as a material adverse change in the Company's business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority of the Lenders’ lien in the collateral or in the value of such collateral. In the event of default by the Company under the Loan Agreement, the Lenders would be entitled to exercise their remedies thereunder, including the right to accelerate payment of the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement, which could harm the Company's financial condition.
 
6. MergerThe Company was in compliance with MabVax Therapeutics, Inc.
On May 12, 2014, the Company entered into a Merger Agreement. Upon the terms and subject to the satisfaction of the conditions described in the Merger Agreement, Tacoma Corp. was merged with and into private company MabVax Therapeutics on July 8, 2014, with MabVax Therapeutics surviving the Merger as a wholly-owned subsidiary of MabVax Therapeutics Holdings. The Merger is intended to qualify as a tax-free reorganization for U.S. Federal income tax purposes.
On July 7, 2014, the stockholders of MabVax Therapeutics Holdings approved the Merger, and the Merger closed and became effective on July 8, 2014. At the effective date of the Merger: (a) all shares of MabVax Therapeutics Series A preferred stock and all shares of MabVax Therapeutics Series B preferred stock were automatically converted into shares of MabVax Therapeutics Holdings common stock, (b) all outstanding shares of MabVax Therapeutics common stock were converted into and exchanged for shares of MabVax Therapeutics Holdings common stock at an exchange rate calculated in accordance with the methodologyapplicable covenants set forth in the MergerLoan Agreement which resulted in 2.223284 shares of MabVax Therapeutics Holdings common stock for every share of MabVax Therapeutics common stock, (c) all outstanding shares of MabVax Therapeutics Series C-1 preferred stock were converted into and exchanged for shares of MabVax Therapeutics Holdings Series A-1 preferred stock at a rate of two shares of MabVax Therapeutics Series C-1 per each share of MabVax Therapeutics Holdings Series A-1 preferred stock, (d) each outstanding MabVax Therapeutics option and warrant to purchase MabVax Therapeutics common stock became options and warrants to purchase shares of MabVax Therapeutics Holdings common stock (and the number of such shares and exercise price was adjusted as calculated in accordance with the methodology set forth in the Merger Agreement), and (e) each outstanding MabVax Therapeutics warrant to purchase MabVax Therapeutics preferred stock was cancelled for no consideration.
As a result of the consummation of the Merger, as of the closing date, the former stockholders, option holders and warrant holders of MabVax Therapeutics were issued, based on the methodology set forth in the Merger Agreement (which excluded certain out of the money convertible securities and calculated others on a net-exercise or cashless basis under the terms of the convertible securities), approximately 85% of the outstanding shares of MabVax Therapeutics Holdings common stock on a fully diluted basis and the stockholders, option holders and warrant holders of MabVax Therapeutics Holdings prior to the Merger owned approximately 15% of the outstanding shares of MabVax Therapeutics Holdings common stock on a fully diluted basis (such percentages calculated based on the methodology set forth in the Merger Agreement). As a result of the Merger, a change of control of MabVax Therapeutics Holdings occurred.
For accounting purposes, the Merger is treated as a “reverse acquisition”. The private company MabVax Therapeutics is considered the accounting acquirer, and the public company MabVax Therapeutics Holdings is considered the legal acquirer and accounting acquiree. The private company MabVax Therapeutics is the accounting acquirer because it owns a majority of the merged company (approximately 85%). As a result, the historical financial statements of the private company MabVax Therapeutics constitute the historical financial statements of the merged companies. The transaction is considered a business combination as MabVax Therapeutics Holdings is considered an operating entity. For accounting purposes, MabVax Therapeutics is treated as the continuing reporting entity.

The issuance of shares of our common stock and preferred stock in the Merger was approved by our stockholders in the annual stockholder meeting held on July 7, 2014. Amendments to our amended and restated certificate of incorporation related to an increase in the authorized number of shares of our common stock and preferred stock and a proposed reverse stock split to maintain NASDAQ listing maintenance standards and other transactions contemplated by the Merger Agreement were not approved at this meeting. As a result of our not getting stockholder approval of a proposed reverse stock split at the July 7, 2014 annual stockholders’ meeting, we were unable to meet all of the listing requirements for the NASDAQ Exchange and our common stock began trading on the OTCQB market under the stock symbol MBVX. There is no impact on accounting for the Merger on July 8, 2014, as a result of not getting stockholder approval on all matters presented at the July 7, 2014 annual meeting.December 31, 2016.
 
The purchase price is based upon the fair value of MabVax Therapeutics Holdings (f.k.a. Telik, Inc.) common stock outstanding of 572,887 shares as of July 8, 2014, multiplied by the stock closing price at July 8, 2014 of $11.20, or approximately $6,416,000. The consideration transferred is based on the market price of MabVax Therapeutics Holdings since management has determined that this was the most reliable measure of fair value, taking into consideration a third party valuation we received for financial reporting purposes as outlined under the Financial Accounting Standards Board Accounting Standards Codification Topic 805: Business Combination in connection with the Merger.

MabVax Therapeutics Series A and MabVax Therapeutics Series B preferred stock (Pre-Merger MabVax Therapeutics Issuances)

During February 2013 through December 2013, the Company sold an additional 410,557 shares of MabVax Therapeutics Series B redeemable convertible preferred stock in exchange for $2,792,993 in funds, net of issuance costs of $7,007. The Company also issued warrants to purchase an additional 194,281 shares of MabVax Therapeutics Series B redeemable convertible preferred stock at an exercise price of $0.01 per share (the “Series B Warrant”). The Series B Warrant is exercisable immediately and has a term of five years. Because the Series B Warrant is immediately convertible at the option of the holder, the Company recorded a deemed dividend of $691,812 from the beneficial conversion feature associated with the issuance of the MabVax Therapeutics Series B redeemable convertible preferred stock and the Series B Warrant.
The Company valued the warrants at fair value at the date the warrants were issued, using the Black Scholes valuation model with the following assumptions; contractual term of five years, volatility of 86%, no dividend yield and a risk-free interest rate of 0.28%.
As of December 31, 2013, the holders of shares of MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock were entitled to cumulative cash dividends of 8% per annum, when and if declared by the MabVax Therapeutics Board of Directors. Such dividends would have been in preference to and prior to any payment of any dividend on shares of MabVax Therapeutics common stock. Cumulative preferred stock dividends, when and if declared, for the MabVax Therapeutics Series A redeemable convertible preferred stock totaled $2,114,818 and the MabVax Therapeutics Series B redeemable convertible preferred stock totaled $430,944, as of December 31, 2013, and were reduced to zero in February 2014 as a result of the MabVax Therapeutics Series C-1 Preferred Stock Financing.
In January 2014, holders of warrants to purchase shares of MabVax Therapeutics Series B redeemable convertible preferred stock exercised their rights to purchase 194,281 shares of MabVax Therapeutics Series B redeemable convertible preferred stock for proceeds of $1,942.
In February 2014, the holders of MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock waived any rights to all prior accrued dividends they may have had a right to receive and amended the MabVax Therapeutics certificate of incorporation to eliminate their right to accrue dividends in the future as an inducement to buyers in the MabVax Therapeutics Series C-1 Preferred Stock Financing. The effect of this change reduced the liquidation preference for the MabVax Therapeutics Series A redeemable convertible preferred stock by $2,187,762 and the MabVax Therapeutics Series B redeemable convertible preferred stock by $486,938 as of February 12, 2014.
No dividends were ever declared by the MabVax Therapeutics Board of Directors since MabVax Therapeutics’ inception on either of the MabVax Therapeutics Series A redeemable convertible preferred stock or the MabVax Therapeutics Series B redeemable convertible preferred stock.
Removal of Redemption Rights – As of December 31, 2013, the holders of a majority interest of the MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock held a right to redeem (the “MabVax Therapeutics Redemption Right”), at any time on or after the fifth anniversary of the issuance date, upon request of at least 60% of the holders thereof, all of their preferred stock at a redemption price of $6.17 and $6.82 per share of MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock, respectively, exclusive of dividends. Due to these terms, MabVax Therapeutics classified all of the MabVax Therapeutics preferred stock as mezzanine equity (outside of permanent equity) as of December 31, 2013. In March 2014, the majority of holders, or more than 60%, of the MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock agreed by letter commitment to MabVax Therapeutics to relinquish the MabVax Therapeutics Redemption Right, and MabVax Therapeutics reclassified the presentation on the consolidated balance sheets as permanent equity following the agreement.
Liquidation preference – As of December 31, 2013, in the event of any voluntary or involuntary liquidation, dissolution or winding up of MabVax Therapeutics, the MabVax Therapeutics Series A redeemable convertible preferred stockholders and MabVax Therapeutics Series B redeemable convertible preferred stockholders were entitled to be paid an amount equal to $6.17 and $6.82 per share, respectively, plus all declared and unpaid dividends, as adjusted to reflect any stock splits, stock dividends or other recapitalization. In addition, after setting apart or paying in full the MabVax Therapeutics Series A redeemable convertible preferred stock and MabVax Therapeutics Series B redeemable convertible preferred stock liquidation preference, any remaining assets of MabVax Therapeutics available for distribution to its stockholders would have been distributed to all stockholders of MabVax Therapeutics with holders of MabVax Therapeutics preferred stock participating on an as converted basis without actually converting their MabVax Therapeutics preferred stock into shares of MabVax Therapeutics common stock. In the event that upon liquidation or dissolution, the assets and funds of MabVax Therapeutics would have been insufficient to permit the payment to MabVax Therapeutics preferred stockholders of the full preferential amounts, then the entire assets and funds of MabVax Therapeutics legally available for distribution were to be distributed ratably first to the holders of MabVax Therapeutics Series B preferred stock, second to the holders of MabVax Therapeutics Series A preferred stock and third on a pro rata basis to all stockholders of MabVax Therapeutics on an as-converted basis.
Series C-1 preferred stock purchase agreement
On February 12, 2014, MabVax Therapeutics entered into a Securities Purchase Agreement (the “MabVax Therapeutics Securities Purchase Agreement”) and issued 3,697,702 shares of MabVax Therapeutics Series C-1 preferred stock, warrants to purchase 2,055,260 shares of MabVax Therapeutics common stock at $3.62 a share (the “MabVax Therapeutics Series C Common Warrants”) and warrants to purchase 1,848,851 shares of MabVax Therapeutics Series C-1 preferred stock at $0.84 a share (the “MabVax Therapeutics Series C Preferred Warrants”), respectively, for aggregate gross proceeds of $3,100,000, less issuance costs of $126,345 (the “MabVax Therapeutics Series C-1 Financing”). The MabVax Therapeutics Series C Common Warrants and Preferred Warrants were exercisable immediately. The MabVax Series C Common Warrants would have expired on February 13, 2022, and the MabVax Therapeutics Series C Preferred Warrants would have expired upon registration of the shares of MabVax Therapeutics common stock (or a successor entity) under the Securities Act. Because the warrants are immediately convertible at the option of the holder, MabVax Therapeutics recorded a deemed dividend of $2,214,911 from the beneficial conversion feature associated with the issuance of the MabVax Series C-1 preferred stock and the MabVax Therapeutics Series C Common Stock Warrants and the MabVax Therapeutics Series C Preferred Stock Warrants.
In connection with the MabVax Therapeutics Series C-1 Financing, MabVax Therapeutics agreed to use its reasonable best efforts to raise at least an additional $3,000,000 through the sale and issuance of shares of MabVax Therapeutics common stock initially intended to be at $15.08 per share (the “Subsequent Capital Raise”). Substantially all of the investors in the MabVax Therapeutics Series C-1 Financing executed a financing commitment letter (such letters, the “Financing Commitment Letters”) to purchase a pro rata number of shares of MabVax Therapeutics common stock at the purchase price of $15.08 per share, representing in the aggregate at least $750,000, subject to certain terms and conditions, including a condition that MabVax Therapeutics raise at least $3,000,000 from new investors in the Subsequent Capital Raise. In addition, each such commitment letter provided that, in the event that less than $3,000,000 was raised from new investors in the Subsequent Capital Raise and subject to certain terms and conditions, each investor party to such letter was required to purchase shares of MabVax Therapeutics preferred stock to be designated as MabVax Therapeutics Series C-2 convertible preferred stock at $15.08 per share and in the aggregate amount of up to $3,000,000 (the “Backstop Capital Raise”).
On May 12, 2014, MabVax Therapeutics and certain investors amended the MabVax Therapeutics Securities Purchase Agreement to, among other things, (i) lower the price per share of the Subsequent Capital Raise from $15.08 to $9.93 per share, and (ii) provide that the price per share payable by investors as set forth in the Financing Commitment Letters would henceforth be the lower of (A) $15.08 a share and (B) the lowest price paid in the Subsequent Capital Raise. The price per share of the Backstop Capital Raise was not changed as a result of the amendment. On July 7, 2014, prior to the Merger, MabVax Therapeutics raised over $3.0 million from the sale of common stock and the Backstop Capital Raise was no longer in effect.

The MabVax Therapeutics Series C-1 preferred stock allowed the holders to require that MabVax Therapeutics redeem their shares of MabVax Therapeutics Series C-1 preferred stock, including any accrued but unpaid dividends, upon the occurrence of any of the following events (each, a “Triggering Event”): (i) the suspension of trading of common stock following registration of such shares, (ii) the failure to issue shares of MabVax Therapeutics common stock upon conversion of any MabVax Therapeutics Series C-1 preferred stock, (iii) the failure to authorize sufficient shares of MabVax Therapeutics common stock to permit the conversion of all outstanding shares of MabVax Therapeutics Series C-1 preferred stock and exercise of all MabVax Therapeutics Series C Common Warrants and MabVax Therapeutics Series C Warrants, (iv) failure to make certain required payments to the holders in excess of $25,000, (v) a default on indebtedness in the aggregate amount of $100,000, (vi) bankruptcy events, (vii) judgments requiring payments in excess of $100,000, (viii) consummation of a change of control with an entity which did not have a class of securities registered for trading, (ix) failure of MabVax Therapeutics to initiate the process of becoming publicly traded (either through a merger into a public company or the filing of a registration statement) within 4 months of the closing of the MabVax Therapeutics Series C-1 Financing, (x) failure to complete such Merger within one year or such registration within 4 months of the closing of the MabVax Therapeutics Series C-1 Financing, (xi) issuance of common stock in violation of certain restrictions relating to employee equity, (xii) issuance of debt in violation of any agreement relating to the MabVax Therapeutics Series C-1 Financing, (xiii) failure to convert MabVax Therapeutics Series A preferred stock or MabVax Therapeutics Series B preferred stock on or prior to the date shares of MabVax Therapeutics common stock became publicly tradable, (xiv) any deviation of 20% or more from the annual budget approved by such holders, (xv) any deviation of 5% or more with respect to auditing and investors’ relations expenses, (xvi) failure to deliver the 2013 audited financials within 45 days of the closing of the MabVax Therapeutics Series C-1 Financing, (xvii) any deviation of any line item of the 2013 audited financials from those set forth in the 2013 unaudited financials delivered in connection with the MabVax Therapeutics Series C-1 Financing or (xviii) a breach of any representation, warranty, covenant or other term or condition of any agreement relating to the MabVax Therapeutics Series C-1 Financing. Certain Triggering Events had occurred as of May 9, 2014, but were subsequently waived by the holders of the MabVax Therapeutics Series C-1 preferred stock.
On July 8, 2014, the date of the Merger, all MabVax Therapeutics Series C-1 preferred stock was converted into shares of MabVax Therapeutics Holdings Series A-1 preferred stock, and the Triggering Events were removed. Because of the removal of the Triggering Events as of the Merger date, the MabVax Therapeutics Holdings Series A-1 convertible preferred stock is presented on the consolidated balance sheet as permanent equity as of December 31, 2014.
Conversion
After giving effect to the Merger and Reverse Split, the holders of our Series A-1 preferred stock may at any time voluntarily convert each share into a number of fully paid shares of our common stock determined by dividing the liquidation preference (described below) by the initial conversion price of $1.6767 per share. Conversion is subject to (a) proportional adjustment for certain dilutive issuances, splits, combinations and other recapitalizations or reorganizations and (b) a full ratchet anti-dilution adjustment upon issuance of shares of common stock (or securities convertible into shares of common stock) at a price per share (or with a conversion or exercise price per share) less than the applicable conversion price, and subject to customary carve outs and exclusions.
Under the terms described for a mandatory conversion, all outstanding shares of our Series A-1 preferred stock shall be automatically converted into shares of our common stock upon the affirmative election of the holders of a majority of the issued and outstanding shares of our Series A-1 preferred stock. In the event that the Company does not issue the shares of its common stock upon conversion of any shares of its Series A-1 preferred stock, certain penalties, which may be paid in the form of cash or additional shares of its common stock, will accrue. The number of shares of our common stock issuable upon conversion of our Series A-1 preferred stock held by any particular holder, together with all affiliates of such holder, is capped at 4.99% of the issued and outstanding shares of common stock of the Company. Any shares in excess of such amount will be held in abeyance until such time as the issuance of such shares of common stock would not put such holder, together will all affiliates of such holder, above 4.99%. An individual holder may elect to increase this limit to up to 9.99% effective 61 days after providing notice to the Company.
Dividends
The Company’s Series A-1 stockholders are entitled to cumulative dividends on each share held at a rate of 8% per annum on the Stated Value (as defined in the Series A-1 certificate of designations) from and after the first date of issuance of any Series A-1 whether or not declared by the Board and whether or not there are funds legally available for the payment of dividends. Such dividends are in preference to and prior to any payment of any dividend on shares of our Series B preferred stock, our Series C preferred stock or our common stock. If any dividend is declared and paid on any shares of our common stock, Series B preferred stock or Series C preferred stock, a dividend shall be declared and paid on shares of our Series A-1 preferred stock on an “as converted” basis. The Company is accreting the dividends in accordance with the agreement.
Liquidation preference
In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, our Series A-1 preferred stockholders shall be paid an amount equal to $1.6767 per share, plus all accrued dividends, as adjusted to reflect any stock splits, stock dividends or other recapitalization. In addition, after setting apart or paying in full the Series A-1 preferred stock, and Series B preferred stock liquidation preference, any remaining assets of the Company available for distribution to stockholders, if any, shall be distributed to all stockholders of the Company with holders of our preferred stock participating on an as converted basis without actually converting their preferred stock into common stock.
In the event that upon liquidation or dissolution, the assets and funds of the Company are insufficient to permit the payment to its preferred stockholders of the full preferential amounts, then the entire assets and funds of the Company legally available for distribution are to be distributed ratably first to the holders of shares of our Series A-1 preferred stock, second to holders of our Series B preferred stock and third on a pro rata basis to all stockholders of the Company on an as-converted basis.
Voting rights
Each holder of our Series A-1 preferred stock is entitled to the number of votes equal to the number of shares of our common stock into which such holder’s shares are convertible. In addition, the consent of the Required Holders (as defined in the Series A-1 preferred stock certificate of designations) is required in certain circumstances.
Registration of Common Stock Issuable upon Conversion of Series A-1 Preferred Stock, and Conversions
On October 14, 2014, the Company filed an Amendment No. 1 to a Registration Statement on Form S-1 (the “Form S-1”) that was initially filed on September 29, 2014, for the purpose of registering additional shares of MabVax Therapeutics Holdings common stock issuable upon conversion of outstanding shares of MabVax Therapeutics Holdings Series A-1 preferred stock.

MabVax Therapeutics Holdings Series B Redeemable Convertible Preferred Stock and Warrants (Pre-Merger MabVax Therapeutics Issuances)
 
On May 12, 2014, (the “Closing Date”), MabVax Therapeutics Holdings entered into a securities purchase agreement (the “Series B Purchase Agreement”) with certain purchasers the “Purchasers” pursuant to which MabVax Therapeutics Holdings agreed to issue and sell, to the Purchasers, subject to customary closing conditions, an aggregate of 1,250,000 shares of MabVax Therapeutics Series B redeemable convertible preferred stockPreferred Stock and warrants (the “Series B Common Warrants”) to purchase up to an additional 78,12510,557 shares of MabVax Therapeutics Holdings common stock, with an aggregate purchase price of $2,500,000, or $2.00 for each share of our Series B redeemable convertible preferred stockPreferred Stock and related Series B Common Warrant (such transaction collectively, the “Series B Private Placement”). The closing of the Series B Private Placement took place on the Closing Date.
On May 8, 2014, MabVax Therapeutics Holdings filed a certificate of designation for the MabVax Therapeutics Holdings Series B preferred stock with the Secretary of State of the State of Delaware. The certificate of designations authorized 1,250,000 shares of Series B preferred stock. Holders of MabVax Therapeutics Series B redeemable convertible preferred stock (the “Holders”) are entitled to cumulative dividends on each share held at a rate of 8% per annum on the Stated Value (as defined in the certificate of designations). Upon a liquidation event, the Holders are entitled to a liquidation preference per share, prior to any distribution of the Company’s assets to the holders of its common stock, in an amount equal to the Stated Value plus accrued and unpaid dividends. After payment to the Holders of the full preferential amount, the Holders will, on a pari passu basis with the holders of the Company’s common stock, participate in the distribution of any remaining assets of the Company, subject to certain limitations. Each Holder may elect to convert their Series B preferred stock into shares of the Company’s common stock at the applicable conversion rate in effect at the time of such conversion. However, the Company shall not effect conversion of the Series B redeemable convertible preferred stock to the extent such conversion would result in the beneficial owner acquiring beneficial ownership of more than 4.99% of the Company’s outstanding common stock post-conversion, including any shares of its common stock issuable upon exercise or conversion of other convertible securities held by such beneficial owner. The Company obtained stockholder approval for the securities being issued in the Series B Private Placement at the annual stockholder meeting held on July 7, 2014. The conversion rate is subject to full ratchet anti-dilution protection upon certain dilutive issuances of our common stock or convertible securities of the Company. Such conversion price will be subject to adjustment from and after the earlier of: (i) the date that some or all of the Registerable Securities (as defined below) have become registered pursuant to an effective registration statement and (ii) six months after the Closing Date at which time the conversion price of the Series B preferred stock shall equal the lower of (a) the initial conversion price and (b) 90% of the average of the 10 lowest weighted average prices of the Company’s common stock during the 20 trading days immediately preceding applicable date of the conversion, of which the latter condition was reached on November 14, 2014. The Holders may also require the Company to redeem their shares of Series B redeemable convertible preferred stock prior to a change of control, as set forth in the certificate of designations. The certificate of designations further provides that the Holders are entitled to certain participation rights on issuances by the Company to holders of common stock in order to maintain their proportionate ownership, subject to certain customary exclusions, such as issuances pursuant to Company option plans, and in connection with the Merger.
The Series B Common Warrants became exercisable six months from the Closing Date, or November 12, 2014, expire five years from the Closing Date and may be exercised for cash or otherwise may be net-exercised. The Series B Common Warrants initially had a per share exercise price of $26.64. On the 60th day following the earlier of (i) the date all of the shares underlying the Warrants become registered pursuant to an effective registration statement and (ii) six months following the Closing Date (in each case, the “Reset Date”), the exercise price shall be reset to equal the lower of (i) the current exercise price and (ii) 90% of the average of the 10 lowest weighted average prices of Common Stock during the 20 trading days immediately preceding the Reset Date. The price was reset to $1.57 on January 11, 2015. The exercise price is subject to full ratchet anti-dilution adjustment for any issuances of common stock and convertible securities for common stock below the current conversion price, consistent with the terms of the Series B preferred stock.

In connection with the Series B Private Placement, the Company also entered into a Registration Rights Agreement with the Purchasers (the “Series B Registration Rights Agreement”). Pursuant to the Series B Registration Rights Agreement, the Company agreed to file a registration statement with the SEC covering resales of the Warrant Shares and the shares issuable upon conversion of the Series B preferred stock (together, the “Series B Registerable Securities”) by the Purchasers no later than 60 days following the Closing Date, and to use its commercially reasonable best efforts to have such registration statement declared effective as soon as practicable. The Company bears all expenses of such registration of the resale of the Registerable Securities. On September 3, 2014, the Required Holders (as defined in the Series B preferred stock certificate of designations) temporarily waived the 60 day registration deadline for a five day period.Warrants.
 
As a result of the Series B Common Warrants’ anti-dilution provision, the Series B Common Warrants arewere recorded as a current liability in the amount of $92,463 on our consolidated balance sheet. The outstanding warrant was valued at $92,463 and $567,885sheet as of December 31, 2014,2014. On March 25, 2015, the Series B Common Warrants were re-valued at $72,656 prior to being exchanged into shares of common stock and July 8, 2014 orSeries D Preferred Stock and the acquisition date, respectively. Our outstanding warrants are revalued on each balance sheet date, with changes inwarrant liability was eliminated and the fair value between reporting periodsCompany recorded in the consolidated statementsa gain of operations.
Warrants are valued using the Black-Scholes-Merton model. The warrant has only partial down round protection, as it has a price reset only on a down round financing, and not an increase in number of shares convertible with the warrant. The Company concluded that using the Black-Scholes-Merton model$19,807 for the valuation as ofyear ended December 31, 2014, is fairly accurate compared to a recent buyout offer. The fair value of warrants is estimated using the following assumptions, which, except for risk-free interest rate, are Level 3 inputs:

Valuation Assumptions
 
The Company used the Black-Scholes-Merton option valuation model, or the Black ScholesBlack-Scholes model, to determine the stock-based compensation expense for stock options recognized under ASC 718.718 and ASC 505. The Company’s expected stock-price volatility assumption was based solely on the weighted average of the historical and implied volatility of comparable companies whose share prices are publicly available. The expected term of stock options granted was based on the simplified method in accordance with Staff Accounting Bulletin No. 110, or SAB 110, as the Company’s historical share option exercise experience did not provide a reasonable basis for estimation. The risk-free interest rate was based on the U.S. Treasury yield for a period consistent with the expected term of the stock award in effect at the time of the grant.

The suit alleged the defendants breached certain fiduciary duties, or aided and abetted a breach of fiduciary duties, in connection with the Company’s Merger with MabVax Therapeutics. In support of their purported claims, the plaintiff alleged, among other things, that the Company’s board has historically failed to fulfill its fiduciary duty to its stockholders, and claiming with respect to the Series B Private Placement and the Merger, the such transactions involved an inadequate sales process and included preclusive deal protection devices, and that the Company’s board of directors would receive personal benefits not available to its public stockholders as a result of such exercise, the Merger.

On July 16, 2014, the Company and all other parties to the litigation entered into an agreement which, if consummated, will settle the litigation (the “Proposed Settlement”). Among many other terms, under the Proposed Settlement the Company and all defendants will receive a broad release of any and all claims pertaining to the Series B Private Placement, the Merger, the prior disclosure and a wide variety of other matters. The Proposed Settlement also calls for the parties to ask the court to, among other things, enter orders enjoining other stockholders from bringing similar actions, certifying the putative settlement class, and approving the Proposed Settlement as a fair, final, and binding resolution of the litigation. Under the Proposed Settlement, the Company and the other defendants have expressly denied the allegations of the complaint and denied engaging in any other misconduct, nor will any of them make any payment or in any respect amend the negotiated terms of the since-consummated Series B Private Placement and Merger. Finally, under the Proposed Settlement, the Company and the other defendants have not agreed to pay any legal fees, or reimburse any expenses, allegedly incurred by the plaintiffs who filed the complaint; instead, the Company expects that counsel for those plaintiffs will present any such disputed claim for legal fees and expenses to the court for resolution.

13. Income taxes
The components of the provision for income taxes for the years ended December 31, 2014 and 2013 is as follows:

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred tax assets are as follows as of December 31, 2014 and 2013:

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that the deferred tax assets will not be realized. Due to such uncertainties surrounding the realization of the Company’s deferred tax assets, the Company maintains a valuation allowance of $13,831,000 against its deferred tax assets as of December 31, 2014. Realization of the deferred tax assets will be primarily dependent upon the Company’s ability to generate sufficient taxable income prior to the expiration of its net operating losses.
During the year, MabVax Therapeutics, Inc. merged with Telik, Inc. in a tax-free reorganization. As a result of the merger, all components of Telik’s deferred tax assets are now included as deferred tax assets of MabVax Therapeutics, Inc. These pre-merger deferred tax assets are net operating loss carryforwards of $1,672,000, research and development credit carryforwards of $3,903,000, as well as other deferred tax asset items of $53,000, in total equaling $5,628,000. The current year change in these assets has been reflected in the provision for income taxes.
As of December 31, 2014, the Company had net operating loss carryforwards of approximately $23,909,000 and $23,773,000 for federal and state income tax purposes, respectively. These may be used to offset future taxable income and will begin to expire in varying amounts in 2028 to 2034. The Company also has research and development credits of approximately $194,000 and $5,960,000 for federal and state income tax purposes, respectively. The federal credits may be used to offset future taxable income and will begin to expire at various dates beginning in 2030 through 2034. The state credits may be used to offset future taxable income, and such credits carryforward indefinitely.

The Company is subject to taxation in the U.S. and California jurisdictions. Currently, no historical years are under examination. The Company’s tax years ending December 31, 2014 and 2013 are subject to examination by the U.S. and state taxing authorities due to the carryforward of unutilized net operating losses and research and development credits.
Utilization of the Company’s net operating loss carryforwards and research and development credit carryforwards may be subject to a substantial annual limitation due to an “ownership change” that may have occurred, or that could occur in the future, as defined and required by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards and research and development credit carryforwards, and other tax attributes that can be utilized annually to offset future taxable income and tax, respectively. Any limitation may result in the expiration of a portion of the net operating loss carryforwards or research and development credit carryforwards before utilization. The net operating loss carryforwards and research and development credit carryforwards inherited as a result of the merger with Telik, Inc. have been severely limited under these rules and will likely not be realized.
In general, an “ownership change” results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50% of the outstanding stock of a company by certain stockholders or public groups. The Company intends to complete a study in the future to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company’s formation, and will complete such study before the use of any of the aforementioned attributes.
The provision for income taxes differs from the amount computed by applying the U.S. federal statutory tax rate (34% in 2014 and 2013) to income taxes as follows:
   2014   2013

The Company has adopted ASC 740-10-25. This interpretation clarifies the criteria for recognizing income tax benefits under ASC 740, “Accounting for Income Taxes”, and requires additional disclosures about uncertain tax positions. Under ASC 740-10-25 the financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement.

Valuation Assumptions
The Company used the Black-Scholes-Merton option valuation model, or the Black-Scholes model, to determine the stock-based compensation expense for stock options recognized under ASC 718 and ASC 505. The Company’s expected stock-price volatility assumption was based solely on the weighted average of the historical and implied volatility of comparable companies whose share prices are publicly available. The expected term of stock options granted was based on the simplified method in accordance with Staff Accounting Bulletin No. 110, or SAB 110, as the Company’s historical share option exercise experience did not provide a reasonable basis for estimation. The risk-free interest rate was based on the U.S. Treasury yield for a period consistent with the expected term of the stock award in effect at the time of the grant.

10. Net Loss per Share
The Company calculates basic and diluted net loss per share using the weighted average number of shares of common stock outstanding during the period.
When the Company is in a net loss position, it excludes from the calculation of diluted net loss per share all potentially dilutive stock options, preferred stock and warrants, and the diluted net loss per share is the same as the basic net loss per share for such periods. If the Company was to be in a net income position, the weighted average number of shares used to calculate the diluted net income per share would include the potential dilutive effect of in-the-money securities, as determined using the treasury stock method.
The table below presents the potentially dilutive securities that would have been included in the calculation of diluted net loss per share if they were not antidilutive for the periods presented.

Valuation Assumptions
The Company used the Black-Scholes-Merton option valuation model, or the Black-Scholes model, to determine the stock-based compensation expense for stock options recognized under ASC 718 and ASC 505. The Company’s expected stock-price volatility assumption was based solely on the weighted average of the historical and implied volatility of comparable companies whose share prices are publicly available. The expected term of stock options granted was based on the simplified method in accordance with Staff Accounting Bulletin No. 110, or SAB 110, as the Company’s historical share option exercise experience did not provide a reasonable basis for estimation. The risk-free interest rate was based on the U.S. Treasury yield for a period consistent with the expected term of the stock award in effect at the time of the grant.

Because the Company had a net operating loss carryforward as of December 31, 2015 and 2016, no tax benefits for the tax deductions related to stock-based compensation expense were recognized in the Company’s consolidated statements of operations. Additionally, there were 376 stock options exercised during the year ended December 31, 2015, and there were no stock option exercises in the corresponding period of 2016.

10. Net Loss per Share
 
The Company calculates basic and diluted net loss per share using the weighted average number of shares of common stock outstanding during the period.
When the Company is in a net loss position, it excludes from the calculation of diluted net loss per share all potentially dilutive stock options, preferred stock and warrants, and the diluted net loss per share is the same as the basic net loss per share for such periods. If the Company was to be in a net income position, the weighted average number of shares used to calculate the diluted net income per share would include the potential dilutive effect of in-the-money securities, as determined using the treasury stock method.
The table below presents the potentially dilutive securities that would have been included in the calculation of diluted net loss per share if they were not antidilutive for the periods presented.

12. Commitments and contingencies
Litigation
On September 18, 2015, an Order and Final Judgment was entered by the Superior Court of the State of California, approving a settlement of a class action lawsuit commenced on May 30, 2014, in Santa Clara County Superior Court, State of California, on behalf of Cadillac Partners and others similarly situated, naming as defendants, MabVax Therapeutics, the Company and the Company’s directors, Hudson Bay Capital Management LP, Bio IP Ventures LLC, Hudson Bay Master Fund Ltd., and Hudson Bay IP Opportunities Master Fund LP, together the “Parties,” alleging the defendants breached certain fiduciary duties, or aided and abetted a breach of fiduciary duties, in connection with the Company’s Merger with MabVax Therapeutics. The plaintiff sought to enjoin the Merger and obtain damages as well as attorneys’ and expert fees and costs.  We expect to incur no expenses in 2016 or thereafter in connection with this lawsuit or settlement.
Capital Leases
On March 21, 2016, the Company entered into a lease agreement with ThermoFisher Scientific (“Lessor”). Under the terms of the agreement, the Company agreed to lease two pieces of equipment from the Lessor, a liquid chromatography system and an incubator, totaling in cost of $95,656. The term of the lease is five years (60 months), and the monthly lease payment is $1,942. In addition, there is a $1.00 buyout option at the end of the lease term.
Minimum future annual capital lease obligations are as follows as of December 31, 2016:
2017
 $23,306

Operating Leases
In connection with the Merger, the Company recorded a $590,504 contingent lease termination fee, related to the termination of the master lease and sublease of the Porter Drive Facility by MabVax Therapeutics Holdings (f.k.a. Telik, Inc.), which is payable to ARE-San Francisco No. 24 (“ARE”) if the Company receives $15 million or more in additional financing in the aggregate. The additional financing was achieved in 2015 and the termination fee is reflected on the balance sheet as an accrued lease contingency fee.
On September 2, 2015,the Companyentered into a lease (the “Lease”) with AGP Sorrento Business Complex, L.P., for certain premises of office and laboratory space in buildings located at 11535 Sorrento Valley Rd., San Diego, California, to serve as the Company’s corporate offices and laboratories (the “New Premises”).  Due to the fact that certain tenant improvements needed to be made to the New Premises before the Company could take occupancy, the term of the Lease did not commence until the New Premises were ready for occupancy, on February 4, 2016.  The Lease terminates six years after such term commencement date, unless earlier terminated in accordance with the Lease. Pursuant to the terms of the Lease, the monthly base rent will be $35,631, subject to annual increases as set forth in the Lease.
The Company has an option to extend the Lease term for a single, five-year period.  If the Lease term is extended for the optional five-year period, the monthly base rent will be adjusted based on fair market rental value.  In addition to rent, the Company agreed to pay a portion of the taxes and utility, maintenance and other operating costs paid or accrued in connection with the ownership and operation of the property.
The Company previously leased its corporate office and laboratory space under an operating lease that, as amended on August 1, 2010, expired on July 31, 2015.
We recognize rent expense on a straight-line basis over the term the lease. Rent expense of $433,397 and $122,236 was recognized in the years ended December 31, 2016 and 2015, respectively.
Minimum future annual operating lease obligations are as follows as of December 31, 2016:

13. Income Taxes
During the years ended December 31, 2016 and 2015, the Company did not record a provision or benefit for current or deferred income taxes in the consolidated statement of operations due to its cumulative net losses.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred tax assets are as follows as of December 31, 2016 and 2015:
 
 
2016
 
 
2015
 
Deferred tax assets:

Net deferred tax assets

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that the deferred tax assets will not be realized. Due to such uncertainties surrounding the realization of the Company’s deferred tax assets, the Company maintains a valuation allowance of $27,901,900 against its deferred tax assets as of December 31, 2016. Realization of the deferred tax assets will be primarily dependent upon the Company’s ability to generate sufficient taxable income prior to the expiration of its net operating losses.
During the year ended December 31, 2014, MabVax Therapeutics, Inc. merged with Telik, Inc. in a tax-free reorganization. As a result of the merger, all components of Telik’s deferred tax assets are now included as deferred tax assets of MabVax Therapeutics, Inc. These pre-merger deferred tax assets are net operating loss carryforwards of $1,588,000, research and development credit carryforwards of $4,457,000, in total equaling $6,045,000. The current year change in these assets has been reflected in the provision for income taxes.
As of December 31, 2016, the Company had net operating loss carryforwards of approximately $50,576,000 and $50,994,000 for federal and state income tax purposes, respectively. These may be used to offset future taxable income and will begin to expire in varying amounts in 2028 to 2035. The Company also has research and development credits of approximately $525,500 and $6,878,000 for federal and state income tax purposes, respectively. The federal credits may be used to offset future taxable income and will begin to expire at various dates beginning in 2030 through 2035. The state credits may be used to offset future taxable income, and such credits carry forward indefinitely.
The Company is subject to taxation in the U.S. and California jurisdictions. Currently, no historical years are under examination. The Company’s tax years ending December 31, 2016 and 2015 are subject to examination by the U.S. and state taxing authorities due to the carryforward of unutilized net operating losses and research and development credits.
Utilization of the Company’s net operating loss carryforwards and research and development credit carryforwards may be subject to a substantial annual limitation due to an “ownership change” that may have occurred, or that could occur in the future, as defined and required by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards and research and development credit carryforwards, and other tax attributes that can be utilized annually to offset future taxable income and tax, respectively. Any limitation may result in the expiration of a portion of the net operating loss carryforwards or research and development credit carryforwards before utilization. The net operating loss carryforwards and research and development credit carryforwards inherited as a result of the merger with Telik, Inc. have been severely limited under these rules and will likely not be realized.
In general, an “ownership change” results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50% of the outstanding stock of a company by certain stockholders or public groups. The Company intends to complete a study in the future to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company’s formation, and will complete such study before the use of any of the aforementioned attributes.
The provision for income taxes differs from the amount computed by applying the U.S. federal statutory tax rate (34% in 2016 and 2015) to income taxes as follows:
 
 
2016
 
 
2015

The Company has adopted ASC 740-10-25. This interpretation clarifies the criteria for recognizing income tax benefits under ASC 740,“Accounting for Income Taxes,”and requires additional disclosures about uncertain tax positions. Under ASC 740-10-25 the financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than not to be sustainable upon audit by the applicable taxing authority. If this threshold is met, the tax benefit is then measured and recognized at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement.

Item 14. Indemnification of Directors and Officers
 
Subsection (a) of Section 145 of the General Corporation Law of Delaware, or the DGCL, empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.
 
Subsection (b) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification may be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.
 
Section 145 of the DGCL further provides that to the extent a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith; that indemnification or advancement of expenses provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and empowers the corporation to purchase and maintain insurance on behalf of a director, officer, employee or agent of the corporation against any liability asserted against him or incurred by him in any such capacity or arising out of his status as such whether or not the corporation would have the power to indemnify him against such liabilities under Section 145.

Reference is also made to Section 102(b)(7) of the DGCL, which enables a corporation in its certificate of incorporation to eliminate or limit the personal liability of a director for monetary damages for violations of a director’s fiduciary duty, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which the director derived an improper personal benefit. Our amended and restated certificate of incorporation provides that we must indemnify our directors to the fullest extent under applicable law. Pursuant to Delaware law, this includes elimination of liability for monetary damages for breach of the directors’ fiduciary duty of care to the CompanyMabVax Holdings and its stockholders. However, our directors may be personally liable for liability:

Item 17.Undertakings
(a)            
The undersigned registrant hereby undertakes:
 
 (1)To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
 (i)To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 (ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
 (iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
 
Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S–3 (§239.13 of this chapter) or Form F–3 (§239.33 of this chapter) and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) (§230.424(b) of this chapter) that is part of the registration statement.

 (2)That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 (3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 (4)
That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
(i)If the registrant is relying on Rule 430B (§230.430B of this chapter):
(A)Each prospectus filed by the registrant pursuant to Rule 424(b)(3) (§230.424(b)(3) of this chapter) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
(B)Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) (§230.424(b)(2), (b)(5), or (b)(7) of this chapter) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) (§230.415(a)(1)(i), (vii), or (x) of this chapter) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or
(ii)If the registrant is subject to Rule 430C (§230.430C of this chapter), each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A (§230.430A of this chapter), shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
(5)That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:
The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 (i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 (§230.424 of this chapter);
 (ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
 (iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
 (iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
 
(b)            The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c)            
The undersigned registrant hereby undertakes that:
