1. Nature of Operations

RXi Pharmaceuticals Corporation (“RXi,” “we,” “our” or the “Company”) is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (“sd-rxRNA^®”) therapeutic platform. The Company’ssd-rxRNA compounds do not require a delivery vehicle to penetrate the cell and are designed to “silence,” or down-regulate, the expression of a specific gene that may be over-expressed in a disease condition. We believe that this provides RXi with a distinct advantage in adoptive cell transfer therapy, the Company’s initial focus and approach to immuno-oncology.

Prior to RXi’sthe Company’s acquisition of MirImmune Inc. in January 2017, the Company’sour principal activities consisted of the preclinical and clinical development of the Company’ssd-rxRNA compounds and topical immunotherapy agent in the areas of dermatology and ophthalmology. In January 2018, after a thorough review of its business operations, development programs and financial resources, the Company made a strategic decision to focus solely on immuno-oncology to accelerate growth and support a potential return on investment for its stockholders. The Company’s current business strategy will focusfocuses on the development of immuno-oncology therapeutics utilizing our proprietary sd-rxRNA technology.

sd-rxRNA technology. The Company plans to finalize its current ongoing clinical trials in dermatology and ophthalmology withRXI-109 and Samcyprone^™ and intends to seek a partner and/orout-license both out-licensee for each of its dermatology and ophthalmology franchises, including RXI-109 and Samcyprone^®, to continue their clinical development and commercialization.development. The goal of any such transaction would be to allow the Company to monetize these preclinical and clinical assets to further fund ongoing and future development work in our immuno-oncology programs and extend our financial runway.

On January 3, 2018, the Board of Directors of the Company approved a1-for-10 reverse stock split of the Company’s outstanding common stock, which was effected on January 8, 2018. All share and per share amounts in the financial statements 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 to additionalpaid-in capital.

2. Liquidity and Going Concern

The Company has limited cash resources, certain limitations under the purchase agreement with Lincoln Park Capital Fund, LLC (“LPC”) and has expended substantial funds on the research and development of the Company’s product candidates and funding general operations. As a result, the Company has reported recurring losses from operations since inception and expects that the Company will continue to have negative cash flows from its operations for the foreseeable future. Historically, the Company’s primary source of financing has been the sale of its securities. The Company’s ability to continue to fund its operations is dependent on the amount of cash on hand and its ability to raise additional capital through, but not limited to, equity or debt offerings or strategic opportunities. This is dependent on a number of factors, including the market demand or liquidity of the Company’s common stock. There can be no assurance that the Company will be successful in accomplishing these plans. As a result, the Company has concluded that there is substantial doubt regarding its ability to continue as a going concern for at least one year. If the Company fails to obtain additional funding when needed, the Company would be forced to scale back or terminate its operations or to seek to merge with or to be acquired by another company. These financial statements do not include any adjustments to, or classification of, recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

3.2. Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures included in the Company’s annual financial statements have been condensed or omitted. Theyear-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation of the condensed consolidated financial statements have been included. Interim results are not necessarily indicative of results for a full year.

Principles of Consolidation

The consolidated financial statements include the accounts of RXi Pharmaceuticals Corporation and its wholly-owned subsidiary.subsidiary, MirImmune, LLC. All material intercompany accounts have been eliminated in consolidation.

Uses of Estimates in Preparation of Financial Statements

The preparation of financial statements in accordance 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from these estimates.

Cash Equivalents and Restricted Cash

The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of amounts invested in certificates of deposit.

Restricted cash consists of certificates of deposit held by financial institutions as collateral for the Company’s corporate credit cards.

Fair Value of Financial Instruments

The carrying amounts reported in the balance sheet for cash equivalents, restricted cash, accounts payable and accrued expenses approximate their fair values due to their short-term nature.

Research and Development Expenses

Research and development costs relate to salaries, employee benefits, facility-related expenses, supplies, stock-based compensation related to employees andnon-employees involved in the Company’s research and development, external services, other operating costs and overhead related to its research and development departments, costs to acquire technology licenses and expenses associated with preclinical activities and its clinical trials. Research and development expenses are charged to expense as incurred. Payments made by the Company in advance for research and development services not yet provided and/or for materials not yet received are recorded as prepaid expenses and expensed when the service has been performed or when the goods have been received. Accrued liabilities are recorded related to those expenses for which vendors have not yet billed the Company with respect to services provided and/or materials that it has received.

Preclinical and clinical trial expenses relate to estimates of costs incurred and fees connected with clinical trial sites, third-party clinical research organizations and other preclinical and clinical related activities and include such items as subject-related fees, laboratory work, investigator fees and analysis costs. Costs associated with these expenses are generally payable on the passage of time or when certain milestones are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. In order to ensure that the Company has adequately provided for preclinical and clinical expenses during the proper period, the Company maintains an accrual to cover these expenses. These accruals are assessed on a quarterly basis and are based on such assumptions as expected total cost, the length of the study, timing of subject visitscertain milestones and other information available to us. Actual results may differ from these estimates and could have a material impact on the Company’s reported results. The Company’s historical accrual estimates have not been materially different from its actual costs.

Stock-based Compensation

The Company follows the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718, “Compensation — Stock Compensation” (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based payment awards made to employees, officers, non-employee directors, andnon-employee directors, non-employees, including stock options. Stock compensation expense based on the grant date fair value estimated in accordance with the provisions of ASC 718 is recognized as an expense over the requisite service period.

For stock options granted as consideration for services rendered bynon-employees, the Company recognizes compensation expense in accordance with the requirements of the FASB ASC Topic505-50, “Equity Based Payments toNon-Employees.”Non-employee option grants that do not vest immediately upon grant are recorded as an expense over the requisite service period of the underlying stock options. At the end of each financial reporting period prior to vesting, the value of these options, as calculated using the Black-Scholes option-pricing model, will bere-measured using the fair value of the Company’s common stock and thenon-cash compensation recognized during the period will be adjusted accordingly. Since the fair market value of options granted tonon-employees is subject to change in the future, the amount of the future compensation expense will include fair valuere-measurements until the stock options are fully vested.

Income Taxes

The Company recognizes assets or liabilities for the deferred tax consequences of temporary differences between the tax basis of assets or liabilities and their reported amounts in the financial statements in accordance with the FASB ASC Topic 740,“Accounting for Income Taxes”.Taxes.” On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act tax reform legislation. This legislation makes significant changes in U.S. tax law including a reduction in the corporate tax rates, changes to net operating loss carryforwards and carrybacks, and a repeal of the corporate alternative minimum tax. There has been no impact to the Company’s income tax expense as a result of the Tax Cuts and Jobs Act. The Company is still assessingcontinuing to assess the impact of the Tax Cuts and Jobs Act and does not expect the other provisions to have a material impact on the Company’s consolidated financial statements.

Comprehensive Loss

The Company’s comprehensive loss is equal to its net loss for all periods presented.

Net Loss per Share

The Company accounts for and discloses net loss per share attributable to common stockholders in accordance with the FASB ASC Topic 260, “Earnings per Share.” Basic and diluted net loss per common share attributable to common stockholders is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share is computed by dividing the Company’s net earnings by the weighted average number of common shares outstanding and the impact of all dilutive potential common shares.

3. Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”)2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU2014-09 states 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. On July 9, 2015, the FASB voted to delay the effective date of the new revenue standard by one year but to permit entities to choose to adopt the standard as of the original effective date. In March 2016, the FASB issued ASU2016-08, “Revenue from Contracts with Customers (Topic 606) – Principal Versus Agent Considerations,”which improves the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU2016-10, “Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and Licensing,” which clarifies two aspects of the guidance on accounting for revenue contracts with customers: identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU2016-12, “Revenue from Contracts with Customers (Topic 606) – Narrow Scope Improvements and Practical Expedients,” which addresses collectability assessment, presentation of sales taxes, noncash consideration and completed contracts and contract modifications at transition. The amendments in these ASUs do not change the core principles for those areas. This standard became effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is not permitted. The Company adopted this ASU in the first quarter of 2018. Since the Company has no significant revenue, this ASU hashad no immediate impact on its consolidated financial statements.

In February 2016, the FASB issued ASU2016-02, “Leases (Topic 842),” which requires companies that are lessees to recognize aright-of-use asset and lease liability for most leases that do not meet the definition of a short-term lease. For income statement purposes, leases will continue to be classified as either operating or financing. Classification will be based on criteria that are largely similar to those applied in current lease accounting. This standard will result in extensive qualitative and quantitative disclosure changes. In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases,” which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02, “Leases.” The FASB further issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements”, in July 2018, which provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption consistent with preparers’ requests.This standard will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. The Company is currently evaluating the impact of this ASU on its consolidated financial statements, but expects that the adoption will result in the current operating lease being recorded on the consolidated balance sheet.

In June 2018, the FASB issued ASU 2018-07, “Compensation – Stock Compensation (Topic 718) – Improvements to Nonemployee Share-Based Payment Accounting,” which expands the scope of ASC 718 to include share-based payment transactions for acquiring goods and services from non-employees. The amendment specifies that ASC 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. This standard will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company early adopted this ASU in the second quarter of 2018. The ASU had no material impact on the Company’s consolidated financial statements.

5.

In August 2018, the Securities and Exchange Commission issued Release No. 33-10532 that amends and clarifies certain financial reporting requirements. The principal change to the Company’s financial reporting will be the inclusion of the annual disclosure requirement of changes in stockholders’ equity in Rule 3-04 of Regulation S-X to interim periods. We will adopt this new rule beginning with our financial reporting for the quarter ended March 31, 2019. Upon adoption, the Company will include the consolidated Statements of Stockholders’ Equity with each quarterly filing on Form 10-Q.

4. Stockholders’ Equity

Lincoln Park Capital Fund, LLC— – On August 8, 2017, the Company entered into a purchase agreement (the “LPC Purchase Agreement”) and a registration rights agreement with LPC, pursuant to which the Company has the right to sell to LPC up to $15,000,000 in shares of the Company’s common stock, subject to certain limitations and conditions set forth in the LPC Purchase Agreement.

During the three months ended March 31,September 30, 2018, the Company sold 270,00015,000 shares of common stock to LPC for net proceeds of approximately $932,000.

April 2018 Registered Direct Offering and Private Placement – On April 11, 2018, the Company closed a registered direct offering of 1,510,604 shares of the Company’s common stock at a purchase price of $3.15 per share (the “April 2018 Offering”) pursuant to the Securities Purchase Agreement dated as of April 9, 2018, by and among the Company and each purchaser identified on the signature pages thereto. In a concurrent private placement, the Company sold warrants (the “Warrants”) to purchase a total of 1,132,953 shares of common stock at a purchase price of $0.125 per underlying warrant share and with an exercise price of $3.15 per share (the “Private Placement”). In connection with the April 2018 Offering and Private Placement, the Company issued warrants to purchase a total of 75,530 shares of common stock with an exercise price of $4.0546 per share to the placement agent, H.C. Wainwright & Co., LLC (the “Placement Agent Warrants”). Assuming the Warrants and Placement Agent Warrants are not exercised, net proceeds to the Company from the April 2018 Offering and Private Placement were $4,210,000 after deducting placement agent fees and offering expenses paid by the Company.

The Company assessed the Warrants and Placement Agent Warrants under the FASB ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and determined that the Warrants and Placement Agent Warrants were outside the scope of ASC 480. The Company next assessed the Warrants and Placement Agent Warrants under the FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). Under the related guidance, a reporting entity shall not consider a contract to be a derivative instrument if the contract is both (1) indexed to the entity’s own stock and (2) classified in stockholders’ equity. The Company determined that the Warrants and Placement Agent Warrants were indexed to the Company’s stock, as the agreements do not contain any exercise contingencies and the settlement amount equals the difference between the fair value of the Company’s common stock price and the strike price. The Company also assessed the classification in stockholders’ equity and determined the Warrants and Placement Agent Warrants met all of the criteria for classification as equity under ASC 815. Based on this analysis, the Company determined that the Warrants and Placement Agent Warrants would be classified in stockholders’ equity.

Warrants —The following table summarizes the Company’s outstanding equity-classified warrants at March 31,September 30, 2018:

No warrants were exercised during the three months ended March 31, 2018 or 2017.

6. Stock-based Compensation

Stock Options

The Company uses the Black-Scholes option-pricing model to determine the fair value of all its option grants. For valuing options granted during the three and nine months ended March 31,September 30, 2018 and 2017, the following assumptions were used:

The weighted average fair value of options granted during the three months ended March 31,September 30, 2018 and 2017 was $3.35$1.72 and $5.10,$4.90, respectively. The weighted average fair value of options granted during the nine months ended September 30, 2018 and 2017 was $1.75 and $4.90, respectively.

The risk-free interest rate used for each grant wasis based upon the yield onzero-coupon U.S. Treasury securities with a term similar to the expected life of the related option. The Company’s expected stock price volatility assumption wasis based upon the volatility of a composition of comparable companies.Company’s own implied volatility. The expected life assumption for employeeoption grants wasis based upon the simplified method provided for under ASC 718, and the expected life assumption fornon-employees was based upon the contractual term of the option.718. The dividend yield assumption is based upon the fact that the Company has never paid cash dividends and presently has no intention of paying cash dividends.

The following table summarizes the activity of the Company’s stock option planoptions for the nine months ended September 30, 2018:

Stock-based compensation expense related to stock options for the three months ended March 31,September 30, 2018 and 2017 was $17,000 and $43,000, respectively.

Stock-based compensation expense related to stock options for the nine months ended September 30, 2018 and 2017 was $95,000 and $276,000, respectively.

Restricted Stock Units

In addition to options to purchase shares of common stock, the Company may also grant restricted stock units (“RSUs”). RSUs are generally subject to graded vesting and the satisfaction of service requirements, similar to our stock options. Upon vesting, each outstanding RSU will be exchanged for one share of the Company’s common stock. The fair value of the RSUs awarded are based on the Company’s closing stock price at the grant date and are expensed over the requisite service period.

The following table summarizes the activity of the Company’s RSUs for the nine months ended September 30, 2018:

During the three and nine months ended September 30, 2018, the Company recorded $22,000 of expense related to RSUs. There was no expense related to RSUs recorded in the same prior year periods. Such expense is included in stock-based compensation expense in the condensed consolidated statement of operations.

Restricted Stock

On August 31, 2018, Geert Cauwenbergh, Dr. Med. Sc., the Company’s Chief Executive Officer, elected the right to receive, in lieu of cash, for the period from September 15, 2018 to December 31, 2018, up to 50% of his base salary and cash bonuses, if any, (collectively, the “Compensation”) payable in the form of unvested, restricted shares of the Company’s common stock. Such restricted shares will be received in the form of a series of grants made on each Company payroll date in lieu of cash payment of the Compensation and shall vest in full on January 1, 2019, subject to his continued employment through such date. The fair value of the restricted stock is based on the Company’s closing stock price on the date of grant and is expensed over the vesting period.

For the three and nine months ended September 30, 2018, the Company granted 73,587 restricted shares of the Company’s common stock in lieu of Compensation to Dr. Cauwenbergh. No stock-based compensation expense was recorded related to the restricted shares for the three and nine months ended September 30, 2018 or 2017. Stock-based compensation expense based on the grant date fair value of the restricted shares will be recognized as an expense over the requisite vesting period, which is expected to occur during the three months ended December 31, 2018.

Compensation Expense Related to Equity Awards

The Company recorded total stock-based compensation expense related to equity awards in the condensed consolidated statement of operations for the three and nine months ended March 31,September 30, 2018 and 2017 as follows, in thousands:

Overview

RXi Pharmaceuticals Corporation is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (“sd-rxRNA^®”) therapeutic platform. Oursd-rxRNA compounds do not require a delivery vehicle to penetrate the cell and are designed to “silence,” or down-regulate, the expression of a specific gene that may be over-expressed in a disease condition. We believe that this provides the Company with a distinct advantage in adoptive cell transfer (“ACT”) therapy, the Company’s initial focus and approach to immuno-oncology.

Prior to the Company’s acquisition of MirImmune Inc. (“MirImmune”) in January 2017, the Company’s principal activities consisted of the preclinical and clinical development of oursd-rxRNA compounds and topical immunotherapy agent in the areas of dermatology and ophthalmology. In January 2018, after a thorough review of our business operations, development programs and financial resources, the Company made a strategic decision to focus solely on immuno-oncology to accelerate growth and support a potential return on investment for its stockholders. The Company’s current business strategy will focusfocuses on the development of immuno-oncology therapeutics utilizing our proprietarysd-rxRNA technology. technology. The Company plans to finalize its current ongoing clinical trials in dermatology and ophthalmology withRXI-109 and Samcyprone^™ and intends to seek a partner and/orout-license both its dermatology and ophthalmology franchises to continue their clinical development and commercialization. The goal of any such transaction would be to allow the Company to monetize these clinical assets to further fund ongoing and future development work in our immuno-oncology programs and extend our financial runway.

In ACT, immune cells are isolated from specific patients or retrieved from allogeneic immune cell banks, which are banks of cells donated from healthy volunteers. The immune cells are then expanded and modified before being returned and used to treat the same patient. We believeour sd-rxRNA compounds are ideally suited to be used in combination with ACT, in order to make these immune cells more effective. Our approach involves the treatment of the immune cells withour sd-rxRNA compounds during the expansion and modification phase. Becauseour sd-rxRNA compounds do not require a delivery vehicle to penetrate into the cells, we are able to enhance these cells (for example, by inhibiting the expression of immune checkpoint genes) by merely adding oursd-rxRNA compounds during the expansion process. After enhancing these cells ex-vivo, they are returned to the patient for treatment. In various types of immune cells tested to date,the sd-rxRNA treatment results in potent silencing while maintaining close to 100% transfection efficiency and nearly full cell viability.

We believe thatour sd-rxRNA therapeutics are uniquely positioned in the immuno-oncology field for the following reasons:

We currently have a pipeline of discovery and preclinical programs to developin three focus areas in which we are aligning our internal research and development efforts with extramural collaborations.

Checkpoint Inhibition in T-Cells

This is our key focus area and our most advanced immuno-oncology program. We have developed sd-rxRNA targeting PD-1, TIGIT and other undisclosed checkpoints in ACT for the treatment of solid tumors. We are alsodeveloping sd-rxRNA against multiple undisclosed targets that influence cell differentiation and metabolism for use in ACT to treat hematologic cancers and solid tumors.

Our most advanced immuno-oncology programsare RXI-762 and RXI-804, sd-rxRNA compounds that are designed to suppress the expression of immune checkpointproteins PD-1 and TIGIT, respectively, which, when used in ACT, are expected to result in an improved efficacy to the targeted tumors.

Our collaboration with the Center for Cancer Immune Therapy at Herlev Hospital, or CCIT, a leading European cancer center, is evaluating the potential of our sd-rxRNA technology platform to enhance the function of tumor-infiltrating lymphocytes (“TILs”) for use in the treatment for a number of cancer types, including melanoma and ovarian cancer. To date, CCIT has evaluated sd-rxRNA compounds targeting immune checkpoints in preclinical screening models of matched TIL/tumor cell pairs from melanoma and cancer patients. Results have shown a marked PD-1 reduction on the surface of TILs in a pilot rapid expansion protocol.

Through our collaboration with Medigene AG, a German biotechnology company developing highly innovative, complementary treatment platforms to target various types and stages of cancer, we are exploring the potential synergies of our sd-rxRNA technology in combination with Medigene’s recombinant TCRs to develop modified T-cells with enhanced efficacy and/or safety with the ultimate goal to further improve Medigene’s T-cell therapies for the treatment of cancer patients. In August 2017,recent studies, Medigene has observed the Company announced the selectionreduction of thesetwoPD-1 surface levels in T-cells transduced with TCRs and treated with our sd-rxRNA compounds for preclinical development in ACT for solid tumors. compound, RXI-762.

We expect to enter clinical developmentwith RXI-762 as part of an ACT therapy for solid tumors withinby the next 12 – 18 months.end of 2019.

Targets Outside of Checkpoint Inhibition in T-Cells and Other Immune Cell Types

This focus area uses our sd-rxRNA in T-cells and other immune cell types, such as natural killer (“NK”) cells and dendritic cells, for targets other than immune checkpoints in order to weaponize and improve cell persistence and cell viability in the immunosuppressive tumor micro-environment. We believe this shows the broad applicability of our platform technology, and that our potential impact in immuno-oncology is not limited to checkpoints and TILs.

We have shown that sd-rxRNAs are advancingrapidly and efficiently taken up by immune effector cells without the use of transfection reagents. Using sd-rxRNA compounds against checkpoint inhibitors, we can suppress their expression levels up to 95% in immune cells, including T-cells and NK cells. Furthermore, we have demonstrated potent silencing activity as well as a phenotypic effect (enhanced degranulation activity) of NK cells treated with sd-rxRNA compounds targeting checkpoints. By treating NK cellsex-vivo, prior to ACT with sd-rxRNA reducing the expression of proteins such as Cbl-b and TIGIT, the anti-tumor response of these cells can be improved. Ongoing work expands these findings to include compounds for more specific NK targets, including NK specific inhibitory receptors, which could be used alone or in combination.

Tumor and/or Tumor Micro-Environment Targets

Our third focus area includes the use of our sd-rxRNA directly towards tumor and/or tumor micro-environment (“TME”) targets. Impacting the tumor cells and/or tumor micro-environment through a direct use of sd-rxRNA, such as via intra-tumoral injection, could potentially become an important form of adjuvant therapy. We believe that this will also show that our contributions with our sd-rxRNA compounds in immuno-oncology are not limited to use with another company’s cell platform. Additionally, the Company has shown that its sd-rxRNA compounds are safe and well-tolerated via intradermal injections and injections in the eye through its completed clinical trials with RXI-109 in dermatology and ophthalmology.

Our collaborative research agreement with Gustave Roussy, a leading comprehensive cancer center in France, concentrates on determining the feasibility of our other discoverysd-rxRNA platform to target TME via intratumoral injection. The goal of our recent study with Gustave Roussy was to identify sd-rxRNA compounds to their target of interest and preclinical ACTdemonstrate efficacy (silencing and phenotypic effect) of sd-rxRNA compounds in a mouse model. Results from this study showed an 80—85% reduction of the target gene in a mouse model of melanoma via intra-tumoral injection.

We continue to advance our sd-rxRNA technology platform towards clinical development in immuno-oncology, both independently and with our strategic collaborations. We plan to focus our internal resources on therapeutic areas where research and development is appropriate for the size and financial resources of the Company and to seek partners in therapeutic areas with the requisite expertise and resources to advance our product and research candidates through clinical development. ToWe believe that end, we have established research collaborations with the Center for Cancer Immune Therapy at Herlev Hospital (a leading European cancer center); Gustave Roussy (a leading comprehensive cancer center in Europe); Medigene AG (a German biotechnology company); and PCI Biotech (a private biotechnology firm).

One aspect ofthis approach to our ongoing strategy iswill allow us to build upon these current collaborations to add additional partnerships to our immuno-oncology pipeline. If results from these collaborationspipeline, support the Company with a shorter path to the clinic by allowing us to utilize and others are positive,build upon already established protocols of our partners and provide us with the synergies between the Company’s technologyopportunity to expand our immuno-oncology programs and its partners technology and expertise may providepipeline in multiple avenues for human clinical testing of the Company’ssd-rxRNA compounds in ACT within the next 12 – 18 months.
