1. Nature of Business 

The terms "MBI"“MBI” or "the Company"“the Company”, "we"“we”, "our",“our” and "us"“us” are used herein to refer to Moleculin Biotech, Inc. MBI is a Phase 2 clinical-stage pharmaceutical company, organized as a Delaware corporation in July 2015, with clinical programs for hard-to-treat cancers and viruses. The Company has three core technologies, each of which have had one or more drugs successfully complete a Phase 1 clinical trial, based substantially on discoveries made at and licensed from The University of Texas System on behalf of the MD Anderson Cancer Center (MD Anderson) in Houston, Texas. The Company has two wholly owned subsidiaries, Moleculin Australia Pty. Ltd., which was set up to perform certain preclinical development and Moleculin Amsterdam B.V., which acts as its legal representative for clinical trials in Europe. The Company utilizes its own internal resources and funds to conduct some of these trials and also has trials being conducted via physician-sponsored trials. The physician-sponsored trials utilize primarily external funds, such as grant funds, which are not presented in these financial statements. The Company does not have manufacturing facilities and all manufacturing activities are contracted out to third parties. Additionally, the Company does not have a sales organization. The Company’s overall strategy is to seek potential out-licensing or outsourcing opportunities with development/commercialization strategic partners who are better suited for the marketing, sales and distributiondistribution of its drugs, if approved.

In 2019, the Company sublicensed its technologies to Animal Life Sciences, Inc. (ALI), to enable research and commercialization for non-human use and share development data. As part of this agreement, ALI issued to the Company a 10% equity interest in ALI. 

On May 5, 2023, the Company received a letter from the Nasdaq Capital Market (Nasdaq) notifying the Company that for the prior 30 consecutive business days the bid price for the Company's common stock had closed below the minimum $1.00 per share requirement for continued inclusion on Nasdaq pursuant to Nasdaq Listing Rule 5550(a)(2) (the "Bid(Bid Price Rule")Rule). The deficiency letter did not result in the immediate delisting of the Company's common stock from the Nasdaq. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided an initial period of 180 calendar days, until November 1, 2023, to regain compliance with the Bid Price Rule. In addition, the Company was required to notify Nasdaq of its intent to cure the minimum bid price deficiency, which may include, if necessary, implementing a reverse stock split. 

On November 2, 2023, the Company received a 180-calendar day extension, until April 29, 2024, from the Nasdaq to regain compliance with Bid Price Rule. TheOn March 5, 2024, the Board of Directors approved a reverse 1-for-15 reverse stock split effective 11:59 P.M. (Eastern time) on March 21, 2024, with trading to commence on a split-adjusted basis on March 22, 2024. On April 8, 2024, the Company will continue to monitorreceived a letter from Nasdaq notifying the Company that it had regained compliance with Bid Price Rule 5550(a)(2) as a result of the closing bid price of itsthe Company's common stock and plans to pursue available options to regainbeing at $1.00 per share or greater for the 10 consecutive business days from March 22, 2024 through April 5, 2024. Accordingly, the Company is in compliance with the Bid Price Rule including potentiallyand Nasdaq considers the Company’s Board of Directors authorizing a reverse stock split, as discussed further below. If the Company authorizes a reverse stock split, it will plan to effectuate the split no later than ten business days prior to the end of the extension in order to timely regain compliance. If, at any time before April 29, 2024, the bid price for the Company's common stock closes at $1.00 or more for a minimum of 10 consecutive business days, the Nasdaq Staff will provide written notification to the Company that it complies with the Bid Price Rule, unless the Staff exercises its discretion to extend this 10 day period pursuant to Nasdaq Listing Rule 5810(c)(3)(G).

On October 3, 2023, the Company held a Special Meeting of Stockholders (the "Special Meeting"). The Company's stockholders granted the Board of Directors the authority to effect an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse stock split of the outstanding shares of the Company’s common stock, at a reverse stock split ratio of between 1-for-5 and 1-for-20 as determined by the Board in its sole discretion, prior to the one-year anniversary of the Special Meeting. The Board of Directors has taken no action with regard to this matter.

If the Company does not regain compliance with the Bid Price Rule by April 29, 2024, the Nasdaq Staff will provide written notification to the Company that its common stock may be delisted. The Company would then be entitled to appeal the Nasdaq Staff’s determination to a NASDAQ Listing Qualifications Panel and request a hearing. There can be no assurance that, if the Company does appeal a delisting determination by the Nasdaq Staff to the NASDAQ Listing Qualifications Panel, that such appeal would be successful. There can be no assurance that the Company will be able to regain compliance with the Bid Price Rule. matter closed.

2. Basis of presentation, principles of consolidation, and significant accounting policies and liquidity 

Reverse Stock Split - On March 22, 2024, the Company completed a reverse stock split of all the issued and outstanding shares of the Company's common stock at a ratio of 1 to 15. The accompanying consolidated financial statements and notes to the consolidated financial statements gives retroactive effect to the reverse stock split for all periods presented. Certain amounts previously reported include rounding up of fractional shares as a result of the reverse stock split.

Basis of Presentation – Condensed Consolidated Financial Information - The accompanying condensed consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) for financial information, and in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (SEC) with respect to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements furnished reflect all normal adjustments, which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of December 31, 20222023 and for the year then ended, including the notes thereto contained in the Form 10-K filed with the SEC on March 22, 2023.2024.

Principles of Consolidation - The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP. The Company views its operations and manages its business in one operating segment. All material long-lived assets of the Company reside in the U.S.

Significant Accounting Policies - The Company's significant accounting policies are described in Note 2, Basis of Presentation, principles of consolidation and significant accounting policies, to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 20222023. There have been no material changes to the significant accounting policies during the ninethree months ended September 30, 2023March 31, 2024.

Use of Estimates - The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of financial statements. Estimates are used in the following areas, among others: fair value estimates on intangible assets, warrants, and stock-based compensation expense, as well as accrued expenses and taxes. 

Going Concern and Liquidity - These condensed consolidated financial statements have been prepared on a going concern basis, which assumes the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The continuation of the Company as a going concern is dependent upon the ability of the Company to obtain necessary equity financing to continue operations and the attainment of profitable operations. As of September 30, 2023March 31, 2024, the Company had an accumulated deficit of $121.3136.6 million since inception and had not yet generated any revenues from operations. Additionally, management anticipates that its cash on hand of $24.616.8 million as of September 30, 2023March 31, 2024 isnot sufficient to fund its planned operations into butfor a period of at least notone beyond the near term.year from when these consolidated financial statements are issued. These factors raise substantial doubt regarding the Company's ability to continue as a going concern. These unaudited condensed consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company may intends to seek additional funding throughone or more of the following: a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. Management cannotThere can be certainno assurance that such events or a combination thereof can be achieved.

 In March 2022, the Company received a subpoena from the SEC requesting information and documents, including materials related to certain individuals (none of which are the Company's officers or directors) and entities, and materials related to the development of and statements regarding the Company's drug candidate for the treatment of COVID-19. The Company has received, and expects to continue to receive, periodic further requests from the SEC staff with respect to this matter. The Company is not aware of the specific nature of the underlying investigation by the SEC, and to the extent that this investigation relates to prior public disclosures that it has made, the Company believes in the accuracy and adequacy of such prior disclosures. The correspondence from the SEC transmitting the subpoena to the Company states that the SEC is trying to determine whether there have been any violations of federal securities laws, but that its investigation does not mean that the SEC has concluded that anyone has violated the law or that the SEC has a negative opinion of any person, entity, or security. The Company cannot predict when this matter will be resolved or what, if any, action the SEC may take following the conclusion of the investigation. TheDuring the three months ended March 31, 2024 and 2023, the Company expensed approximately $0.4approximately $0.1 million and $1.1 million$0.5 million, respectively, in related general and administrative fees and expenses for the three months ended September 30, 2023 and 2022, respectively, and $1.4 million and $1.9 million for the nine months ended September 30, 2023 and 2022, respectively.expenses. The Company is in the process of filing a claim with its insurance carriers related to this loss which may cover a portion of the related expenses but not all. The claim is currently under review by the insurance company. The claim has not yet been approved nor has a reimbursement amount been determined.determined which, if any, would be limited by the applicable retention as defined under the policy. Accordingly, the Company has not recorded any provision for insurance reimbursement. The Company expects to record the insurance reimbursement at the time that the amount to be reimbursed is determined and approved by the insurance carrier. Any insurance reimbursement receivable will be recorded at an amount not to exceed the recorded loss and only if the terms of the legally enforceable insurance contracts support that the insurance recovery will not be disputed and is deemed collectible, or if recovery of the loss is probable.

Cash and Cash Equivalents - Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents. The Company maintains cash accounts principally at one financial institution in the U.S., which at times, may exceed the Federal Deposit Insurance Corporation’s limit. The Company has not experienced any losses from cash balances in excess of the insurance limit. The Company’s management does not believe the Company is exposed to significant credit risk at this time due to the financial condition of the financial institution where its cash is held. 

Fair Value of Financial Instruments - The Company's financial instruments consist primarily of non-trade receivables, accounts payable, accrued expenses and its warrant liability. The carrying amount of non-trade receivables, accounts payable, and accrued expenses approximates their fair value because of the short-term maturity of such.

The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with U.S. GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:

Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.

Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

Level 3 – Unobservable inputs for the asset or liability.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of warrant liability discussed in Note 4.

The following table provides the financial liabilities reported at fair value and measured on a recurring basis at September 30, 2023March 31, 2024 and December 31, 20222023 (table in thousands): 

The table below of Level 3 liabilities (table in thousands) begins with the valuation as of the beginning of the thirdfirst quarter and then is adjusted for changes in fair value that occurred during the thirdfirst quarter. The ending balance of the Level 3 financial instrument presented above represents the Company's best estimates and may not be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. 

The table below of Level 3 liabilities (table in thousands) begins with the valuation as of December 31, 2022 and then is adjusted for changes in fair value that occurred during the nine months ended September 30, 2023. The ending balance of the Level 3 financial instrument presented above represents the Company's best estimates and may not be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. 

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. For purposes of this calculation, options to purchase common stock, restricted stock units subject to vesting and warrants to purchase common stock are considered to be common stock equivalents. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive. For the three months ended September 30, 2023March 31, 2024 and 20222023, approximately 8.51.7 million and 6.0 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to their anti-dilutive effect. For the nine months ended September 30, 2023 and 2022, approximately 7.0 million and 5.20.4 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to their anti-dilutive effect.

Subsequent Events - The Company’s management reviewed all material events through the date of these unaudited condensed consolidated financial statements. See Note 8 - Subsequent Events. 

Recent Accounting Pronouncements - There are no recently issued accounting standards updates that are currently expected to have a material impact on the Company.

Accrued expenses and other current liabilities consist of the following components (in thousands):

Additionally, accounts payable includes $64,000includes $74,000 and $67,000 as of September 30, 2023March 31, 2024 and December 31, 20222023, respectively, for related party payables.

4. Warrants

Liability Classified Warrants

The Company uses the Black-Scholes option pricing model (BSM) to determine the fair value of its warrants at the date of issue and outstanding at each reporting date. The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds linearly interpolated to obtain a maturity period commensurate with the term of the warrants. Estimated volatility is a measure of the amount by which the Company's stock price is expected to fluctuate each year during the expected life of the warrants. Only the volatility of the Company's own stock is used in the Black-Scholes option pricing model. 

The assumptions used in determining the fair value of the Company's outstanding liability classified warrants are as follows:

A summary of the Company's liability classified warrant activity during the ninethree months ended September 30, 2023March 31, 2024 and related information follows: 

For a summary of the changes in fair value associated with the Company's warrant liability for the ninethree months ended September 30, 2023March 31, 2024, see Note 2 - Basis of presentation, principles of consolidation and significant accounting policies - Fair Value of Financial Instruments.

Equity Classified Warrants

In August 2023,March 2024, the Company granted equity-classified warrants to purchase up to 100,0003,334 shares of Company common stock with a five-year term and an exercise price of $0.62.

During theThe Company did ninenot months ended September 30, 2023, pursuant toutilize the 2021 Lincoln Park purchase agreement during the Company issued to Lincoln Park 225,568 shares of common stock for gross proceeds of $0.2 million.three months ended March 31, 2024. The 2021 Lincoln Park Agreement, which has $19.8 million available as of September 30, 2023March 31, 2024, terminates on July 1, 2024. The Company is in discussions with Lincoln Park Capital to effect the extension of this agreement. The Company intends to seek an extension of this agreement prior to termination, however no agreement has been reached as of the date these unaudited consolidated financial statements were issued. In the December 2023 Offering, the Company agreed not to utilize the Lincoln Park Agreement or any such extension thereof, until after June 26, 2024.

Other Components of Equity 

In March 2023, the Company and WPD Pharmaceuticals (WPD) agreed to terminate the WPD Agreement (defined below). Pursuant to the termination, the Company agreed to pay WPD (or its designees) $700,000 in cash and shares of its common stock valued at $800,000. In March 2023,2024, the Company issued 822,1156,834 shares of common stock to WPD (or its designee) as part of satisfying this commitment. See Note 7 - Commitments and Contingencies. In addition, during the nine months ended September 30, 2023, the Company issued 134,933 shares of common stock relatedconsultants in exchange for services to the vesting of restricted stock units.be provided. 

Stock-Based Compensation and Outstanding Awards

The 2015 Stock Plan provides for the grant of stock options, stock awards, stock unit awards, and stock appreciation rights to employees, non-employee directors and consultants. In May 2023 and 2022, the 2015 Stock Plan (the Plan) was amended to authorize an additional 1,750,000116,667 shares and 2,000,000133,334 shares, respectively, such that 5,500,000366,667 total shares may be issued under the Plan. As of September 30, 2023March 31, 2024, there were 27,7522,053 shares remaining to be issued under the 2015 Stock Plan. 

Stock-based compensation expense for the three and ninemonths ended September 30, 2023March 31, 2024 and 20222023, respectively, is as follows (table in thousands):

The restricted stock units vest annually in four equal installments. 

6. Income Taxes  

Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

The Company does not expect to pay any significant federal, state, or foreign income taxes in 20232024 as a result of the losses recorded during the three and ninemonths ended September 30, 2023March 31, 2024 and the additional losses expected for the remainder of 20232024 and cumulative net operating loss carryforwards. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all of the benefits of deferred tax assets will not be realized. As a result, as of September 30, 2023March 31, 2024 and December 31, 20222023 the Company maintained a full valuation allowance for all deferred tax assets.

The Company recorded no income tax provision for the three and ninemonths ended September 30, 2023March 31, 2024 and 20222023, respectively. The effective tax rate for the ninethree months ended September 30, 2023March 31, 2024 and 20222023 is nilnil.. The income tax rates vary from the federal and state statutory rates primarily due to the change in fair value of the stock warrants, Internal Revenue Code Section 162(m) limitations and ISO activity, as well as the valuation allowances on the Company’s deferred tax assets. The Company estimates its annual effective tax rate at the end of each quarterly period. Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation allowance could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.

7. Commitments and Contingencies

In addition to the commitments and contingencies described elsewhere in these notes, see below for a discussion of the Company's commitments and contingencies as of September 30, 2023March 31, 2024.

Lease Obligations Payable

The following summarizes quantitative information about the Company's operating leases for the three and ninemonths ended September 30, 2023March 31, 2024 and 20222023, respectively (table in thousands):

In September 2023, the Company executed an amendment to extend the corporate office lease until August 31, 2029, with an option to renew. The Company is required to remit base monthly rent of approximately $4,700 which will increase at an average approximate rate of 2% each year. The Company is also required to pay additional rent in the form of its pro-rata share of certain specified operating expenses of the building.

Our Business

We are a clinical stage pharmaceutical company with a growing pipeline, including Phase 2 clinical programs for hard-to-treat cancers and viruses. We have three core technologies, each of which have had one or more drugs successfully complete a Phase 1 clinical trial, based substantially on discoveries made at and licensed from the University of Texas MD Anderson Cancer Center (MD Anderson) in Houston, Texas. Three of our six drug candidates have shown human activity in clinical trials and are currently or have been in Phase 1B/2 or Phase 2 clinical trials. Since our inception and as of March 2024, our drugs have completed, are currently in, or have received approvalbeen permitted to proceed in, eleventhirteen clinical trials. Annamycin is our lead molecule and is in three Phase 1B/2 clinical trials - one for treating Acute Myeloid Leukemia (AML) and two for treating Soft Tissue Sarcoma metastasized to the lungs (STS lung metastases, STS lung mets, or Advanced STS).

One of our core management beliefs is that anthracyclines represent the most important treatment for AML and Advanced STS, and we believe Annamycin may, for the first time ever, allow a majority of these patients to benefit from this treatment. This belief leads us to currently focus mainly on the development of Annamycin.

Our Core Technologies

Our core technologies consist of the following:following programs:

a) Annamycin or L-Annamycin is a “next generation” anthracycline (one of the most common formswidely used classes of chemotherapy), designed to be different than currently approved anthracyclines, which are limited in utility because of cardiotoxicity risks and their susceptibility to multidrug resistance mechanisms. Annamycin was designed to avoid multidrug resistance and to be non-cardiotoxic and has shown no cardiotoxicity in subjects treated in clinical trials to date. Furthermore, we have demonstrated safe dosing beyond the dose limitations imposed by regulatory authorities upon currently prescribed anthracyclines due to their inherent cardiotoxicity;

b) our WP1066 Portfolio, which includes WP1066 and WP1220,cardiotoxicity. As of March 2024, Annamycin demonstrated efficacy in two of several Immune/Transcription Modulators in the portfolio designed to inhibit p-STAT3 (phosphorylated signal transducer and activator of transcription 3) among other transcription factors associated with tumor activity, while also stimulating a natural immune response to tumors by inhibiting the errant activity of Regulatory T-Cells (TRegs); and

c) our WP1122 Portfolio, which contains compounds (including WP1122, WP1096, and WP1097) designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (2-DG), which we believe may provide an opportunity to cut off the fuel supply of tumors by taking advantage of their high level of dependence on glucose in comparison to healthy cells, as well as viruses that depend upon glycolysis and glycosylation to infect and replicate.

In discussions regarding Annamycin’s lack of cardiotoxicity, we rely on our expert's assessment of certain clinical trial subject data including LVEF, ECHO strain analyses, and cardiac biomarkers – troponins I & T and our pre-clinical and clinical data, some of which are preliminary and subject to change.

Our Focus

We are focused on internally funded development of:

1) Annamycin for the treatment of Soft Tissue Sarcoma metastasized to the lungs (STS lung metastases or STS lung mets)

2) Annamycin in combination with Cytarabine (also known as Ara-C, the combination with Annamycin is referred to as AnnAraC) for the treatment of Acute Myeloid Leukemia (R/R AML or AML).

3) A better formulation for delivery of WP1066 to further support current and possibly future externally funded oncology clinical trials. 

We have also recently established a Recommended Phase 2 Dose (RP2D) for WP1122 to potentially enable future externally funded oncology and virology trials. Beyond this, we support development of our core technologies through several externally funded clinical trials and primarily externally funded non-clinical research, with the potential for further studies in the future.

Our Clinical Trials

In the US and Europe, since our inception, we or independent investigators have approval to begin, are currently conducting or have completed eleven internally or externally funded clinical trials for four of our drug candidates – Annamycin, WP1066, WP1220, and WP1122. All clinical trials are or were in the Phase 1 or 2 stage. During 2021, we had four active clinical trials evaluating either Annamycin or WP1066 in the US and Europe. This increased to six active or recently completed trials in 2022 involving Annamycin, WP1066, and WP1122. Starting in 2021 through 2023, there have been seven "right-to-try" (or their foreign equivalent) uses of Annamycin and WP1066. Three of the six clinical trials active in 2022 were internally funded trials of Annamycin and one was an internally funded Phase 1 clinical trial for WP1122 establishing an RP2D.

Moving into 2023 with our internally funded trials focused on Annamycin, we were actively recruiting in two Phase 1B/2 stage clinical trials and have concluded one Phase 1 trial. We have recently concluded recruitment and treatment in one of theits Phase 1B/2 trials but are still monitoring progression free survivalin subjects with AML and overall survival. This now leaves only one Phase 1B/2 clinical trial active with regardAdvanced STS. We believe that Annamycin has potential to recruitingfill an unmet need as a second line therapy (2nd line or 2L) in AML and treatment. Bothpotentially as first line therapy in Advanced STS.

As part of these Phase 1B/2our Annamycin clinical trials, are open label, so we periodically announce safety and efficacy data.

In February 2023, the externally funded Phase 1 clinical trial with WP1066 for the treatment of pediatric brain tumors concluded. We expect up to two externally funded Phase 1B/2 clinical trials for WP1066 in the treatment of GBM and other brain tumors in the first half of 2024. One more pediatric clinical trial may occur later subject to the results of the other two possible clinical trials.

During 2022 and 2023, we or independent investigators filed applications, began recruiting or are currently recruiting for six internally or externally funded clinical trials in the US and Europe.

Additionally, we are in discussions with research institutions in the US and Asia regarding possible externally funded trials or programs involving WP1066.

New Positive Independent Report of No Cardiotoxicity in Annamycin

In September 2023, we received a new independent assessment for the absence of cardiotoxicity in subjects treated with Annamycin. We now have independent assessments covering 62 subjects that have been treated with Annamycin in four different clinical trials in the U.S. and Europe with no evidence of cardiotoxicity. 50 of all 66 subjects treated to date (which includes the 62 subjects independently assessed) were treated above the FDA’s lifetime maximum anthracycline limit of 550 mg/m², with 1 subject having been treated with 3420 mg/m² (or roughly six times the FDA approved lifetime anthracycline exposure) of standard anthracyclines and Annamycin with no evidence of cardiotoxicity.

Data from all subjects in our completed and all evaluable subjects in our ongoing clinical trials (a total of 62 subjects as of the most recent report) were made available to an expert in chemotherapy who is affiliated with a leading research institute in assessing chemotherapy-related cardiotoxicity. After review of this data, the independent expert in their most recent report, concluded that there was no evidence of cardiotoxicity.

to assess cardiotoxicity associated with chemotherapy at the Cleveland Clinic (Expert or Independent Expert). The data made available includedto the Expert includes left ventricular ejection fraction (LVEF) as determined by echocardiograms, and ECHO strain imaging, andas well as Troponin levels.levels (a biochemical marker of acute heart damage). “ECHO strain imaging” is a method in echocardiography (medical ultrasound) for measuring regional or global deformation (contraction or beating) of the myocardium (heart muscle). By strain rate imaging, the simultaneous function of different regions can be displayed and measured. Cardiac health biomarkers such as blood Troponin levels are considered an indicator of potential long-term heart damage. The Expert has issued and will continue to issue periodic reports as additional data are provided to him in batches of subject data. Such data include some data which are preliminary and subject to change. In our discussions regarding the lack of Annamycin's cardiotoxicity, we rely on the Expert's assessment.

Annamycin benefits from a promising advancement in lipid enabled drug delivery developed in collaboration with and exclusively licensed from MD Anderson. The unique patented lipid composition allows us to combine a new concept in chemotherapeutic agents within a lipid structure that helps target the delivery of the payload and reduce the potential for toxicity. In the case of Annamycin, our unique use of lipid technology enables improved tissue/organ distribution, and as demonstrated in multiple clinical trials, dramatically reduced toxicity, including cardiotoxicity.

b) Our WP1066 Portfolio includes WP1066, WP1193 and WP1220, three of several Immune/Transcription Modulators in the portfolio designed to inhibit p-STAT3 (phosphorylated signal transducer and activator of transcription) among other transcription factors associated with tumor activity. These also stimulate a natural immune response to tumors by inhibiting the errant activity of Regulatory T-Cells (TRegs). WP1066, in oral formulation, has been in two clinical trials, including compassionate use cases. WP1066 and WP1193 are being tested in preclinical programs in intravenous (IV) formulations. WP1066 and WP1220 have been in clinical trials in a topical formulation. WP1066 and WP1220 have both independently successfully completed Phase 1 clinical trials and have demonstrated efficacy.

c) Our WP1122 Portfolio contains compounds (including WP1122, WP1096, and WP1097) designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (2-DG). We believe such compounds may provide an opportunity to cut off the energy supply of tumors by taking advantage of their high degree of dependence on glucose in comparison to healthy cells, as well as viruses that also depend upon glycolysis and glycosylation to infect and replicate. WP1122 has completed a Phase 1 clinical study, successfully establishing a Recommended Phase 2 Dose or RP2D.

MB-106 Annamycin in Combination with CytarabineClinical Trial for the Treatment of AML (in Combination with Cytarabine (MB-106)“

5+3 TherapyTable 1”

)Note 1 for Table 1: Data from MB-106 is for Intent To Treat (ITT) subjects and is preliminary and subject to change. Median Durability of CRc is 4.9 months and climbing.

On May 2, 2023, we announced successful completion7, 2024, our management held a Key Opinion Leader conference call with Dr. Martin Tallman and Dr. Michael Andreeff. Management made a presentation of the first cohort in our Phase 1B portiondata above and discussion ensued with Drs Tallman and Andreeff on the significance of this data. Both Drs. Tallman and Andreeff are members of our Science Advisory Board.

The call included a discussion of the results to date for MB-106. We believe that the Phase 1B/2 clinical trial usinghas been successful in establishing safety and efficacy of Annamycin in combination with Cytarabine (AnnAraC) for the treatment of AML, (MB-106). This study is utilizingand in providing sufficient data to support a “5+3” regimen where Annamycin is administered with three days of infusion along with the five days of infusion of Cytarabine. This combination strategy is similarPhase 2 registration-directed clinical trial (MB-108) to the familiar “7+3” induction therapy that is consideredfurther provide data for efficacy which we intend to be a standard of care in AML, where seven days of Cytarabine infusions are paired with three days ofuse to support an approved anthracycline (typically, daunorubicin). In the first cohort 3 subjects were treated, all of whom were relapsed from multiple prior therapies. Annamycin was dosed at 190 mg/m², along with Cytarabine at 2.0 g/m²/dayeventual application for five days (total dose of 10g/m²)New Drug Approval (NDA). We, at the recommendation of the safety review committee, deemed the first cohort dose as safe

Preliminary Safety, Efficacy and opened the second cohort with the Annamycin dose being increased to 230 mg/m². Durability Data

The medianpreliminary data for MB-106 demonstrate a CRc rate of 45% and an ORR of 55% for all subjects, regardless of the number of prior therapiestreatments (N=20). Segmenting the MB-106 subject population for these 3 subjects1^st line (N=3) and, most notably, 2^nd line (N=10) therapies in the first cohort was five (rangetrial, yields a CRc rate of 67% and 60% and an ORR of 67% and 70%, both respectively. We believe the CR and CRc rates demonstrated by AnnAraC in 2^nd line patients substantially exceeds the performance reported by any drug currently approved for use in 2^nd line AML.

Median durability of remission (DoR) for the 9 CRcs is approximately 4.9 months and developing with one death (related to ten). 1 subject, who was 78 years of age at the timepneumonia) and one relapse to date out of the studyten CRcs. The first subject with a CRc (and who has yet to relapse) was treated in February 2023. The DoR is being measured from the initiation and enrolled after a single prior multi-year therapy, achieved a CR that has continued to be durable at approximately eight months. This subject has received a second course of treatment at the direction of the treating physician and as allowed per the protocol. The other 2 subjects were shown to have disease progression.relapse or death.

On August 7, 2023, we successfully completed the second cohort at 230 mg/m² Cardiovascular safety of Annamycin in this combination study. 4is thoroughly monitored as independent assessments are made by an independent expert cardio-oncologist from Cleveland Clinic. As of April 1, 2024, data from 84 subjects were treated in this cohort, 1 is believed to be relapsed from one or more prior therapiesacross five trials (AML & STS, internal and 3 are believed to be refractory from up to three prior therapies. 1 subject was replaced due to a Serious Adverse Event (SAE) experienced on Day 1 of dosing. The SAE was determined to be unrelated to Annamycin and definitively related to Cytarabine. We, at the recommendation of the safety review committee, deemed the second cohort dose as safe and opened recruitment, including for both first line therapy and for subjects who are refractory to or relapsed after induction therapy, to the Phase 2 portion of the trial. The median number of prior therapies for the 3 evaluable subjects in the second cohort was two (range of one to three) and the median age was 67. 1 subject, who was 64 years of age at the time of enrollment into the study with one prior therapy, was preliminarily recorded as a complete response with an incomplete recovery of the bone marrow or CRi per the protocol. This has sinceexternally funded trials) have been deemed a CR (complete response), which has shown to be durable for approximately three months, which has allowed this subject to proceed to a bone marrow transplant. The other 2 subjects were shown to have disease progression. Durability of CRs is confirmed by repeat bone marrow aspirates (BMA's). 

The total CRs in the Phase 1B portion of this combination trial represent 33% (n=6). Notably, these CRs are considered durable. The median agereviewed. Of note, most of these subjects was 66.

On October 2, 2023, we announcedhave received greater than the initiallifetime cumulative anthracycline dose above 550 mg/m2 associated with increased risk of cardiomyopathy. Some subjects had been treated in the Phase 2 portionhave received four times this amount following Annamycin administration(s). No signal of MB-106. The data below are as reported by the investigation sites as of November 9, 2023.

We have recruited, treated, and evaluated 3 subjects in the Phase 2 portion of the trial. 1 subjectcardiotoxicity has been evaluated and determined to be a CR. We will assess durability in the near future. Another subject in the Phase 2 portion died from a stroke (deemed not be related to Annamycin) prior to being re-biopsied to determine disease status. The third has undergone a re-biopsy which shows zero blasts in the marrow and that data is now being assessed by the investigator. This latest subject is not included in the chart below. The median age of the first two subjects is 69 years (range of 69 to 70) and the median number of prior therapies for these subjects is three (both are three). Other subjects in the Phase 2 portion of the trial are in the process of screening and treatment. We intend to treat up to 21 subjects in this Phase 2 portion of the trial. We may recruit an additional 3 subjects depending on recruitment. At our rate of recruitment plus the addition of another three sites for the trial, we expect to complete recruitment by early 2024.

The total CR response rate in both Phases to date in MB-106 is 38% (n=8), and although sufficient time has not passed to assess durability for the latest of these CRs, the 2 earliest CRs have now shown durability. The median baseline bone marrow assessments for the 3 CRs was 74.2 (range of 20 to 80). CRc is used to denote composite complete responses including CRs and CRis.identified.

Below in Table 1 is a summary of the above responses in MB-106 and in the concluded MB-105 monotherapy trial on AML.

MB-107U.S Patents for Annamycin Monotherapy for the Treatment of STS Lung Mets

On September 21, 2023,April 9, 2024, the United States Patent and Trademark Office (USPTO) issued U.S. Patent number 11,951,118 titled, “Preparation of Preliposomal Annamycin Lyophilizate” (the ‘118 patent’) to Moleculin and The University of Texas System Board of Regents. On April xx, 2024, we announcedreceived an Issue Notification from the completionUSPTO for an additional patent (U.S. Patent number 11,980,634) titled “Method of enrollment inReconstituting Liposomal Annamycin” (the ‘634 patent’) to be issued on May 14, 2024.

The ‘118 patent provides claims to compositions that contain Annamycin, and the Phase 2 portion of our U.S. Phase 1B/2 clinical trial evaluating‘634 patent, when issued, will provide claims to liposomal Annamycin as monotherapysuspension compositions, both with a base patent term extending until June 2040, subject to extension to account for time required to fulfill regulatory requirements for FDA approval. Moleculin’s novel candidate for the treatment of acute myeloid leukemia (AML) and soft tissue sarcoma lung metastases (MB107). Subjects who had stable disease at(STS lung mets) uses a unique lipid-based delivery technology. In addition to the timeissued ‘118 and expected ‘634 U.S. patents, we have additional patent applications pending in major jurisdictions worldwide. 

EMA issues ODD to Annamycin for the treatment of study discontinuation will continueAML

We announced that the European Medicines Agency (EMA) has granted Orphan Drug Designation (ODD) to be followedAnnamycin for progression free response and overall survival. All subjects had pulmonary metastasis from soft tissue sarcoma and at least one prior therapy. There was no limit on how many prior therapies a subject couldthe treatment of AML. Combined with the Orphan Drug Designation we have prior to entering this study. Most subjects were heavily treated with other therapies prior to entering our trial with our treatment representing the fourth median therapy for all subjects in the Phase 1BUS and Phase 2 portionwith the new composition of the trial (range of two to twelve). As of November 6, 2023, as reportedmatter and formulation patents just awarded by the investigation sites, most subjects in Phase 2 are alive so overall survival data are not available at this time. Below in Table 2 is a summary of progression free survival for evaluable subjects, as discussed further below, by groupingsUS Patent and median overall survival for all subjects evaluable in Phase 1B:

In the Phase 1B portion of the trial subjects were treated from 210 mg/m² to 390 mg/m². In the Phase 2 portion of the trial, an exploratory RP2D of 360 mg/m²was initiated for the first 3 subjects and a final RP2D of 330 mg/m² was determined and 14 subjects were treated.

Including the 3 subjects treated at the same dose in the Phase 1B portion of this trial, this equates to 17 total subjects measurable for efficacy at the 330 mg/m² dose level. Including all measurable subjects at all dose levels in the Phase 1B portion of the trial, 32 subjects were treatedTrademark Office with at least one cycle in this study and 27 received at least two cycles of treatment. For the Phase 2 subjects, the median time to entering the MB107 trial from the time of initial diagnosis is estimated to be approximately 20 months, and these subjects have been mostly heavily treated previously for STS lung mets prior to entering our study.

Once all data are collected, we plan a more in-depth presentation of the topline data for this study in 2024. The above information in Table 2 was shared with our investigators in a meeting held during the Connective Tissue Oncology Society Annual Meeting (CTOS) in Dublin, Ireland in early November 2023. Based on the data as shown in Table 2 above,coverage through 2040, we believe the following observations are in order:commercial exclusivity of Annamycin is now well protected.

WP1066

We continue discussions with two US academic institutions and another foreign academic institution for externally funded trials for the use of WP1066 for the treatment of glioblastomas and/or pediatric brain tumors. We expect to finalize agreementsOf note, we have finalized an agreement with Northwestern University (NU) and FDA filingswe expect NU to initiate an investigator initiated glioblastoma study in the second half of this yearnear-term (Clinicaltrials.gov ID: NCT05879250). We do not expect the pediatric study to begin until an adult brain tumor trial commences and generates additional data.

Regarding an intravenous formula for WP1066, we continue to work towardsbelieve that substantial progress has been made and we believe we will be able to announce progress regarding an IV formulation in the near the end of 2023 or in early 2024.term.

WP1122

With the data generated from the MB-301 clinical trial setting an RP2D for WP1122 and additional sponsored research, we continue to explore avenues of external funding for further development of this portfolio. For this study, we have submitted the final clinical study report in late October 2023.

Other Trials and Publications 

Presented Poster at the 2023 Connective Tissue Oncology Society (CTOS) Annual Meeting

We presented preliminary efficacy findings from the Phase 2 portion of our ongoing MB-107 in an abstract titled, “A Phase 1b/2 Study of Liposomal Annamycin (ANN) in Subjects with Previously Treated Soft-Tissue Sarcomas (STS) with Pulmonary Metastases,” was presented by Brian Andrew Van Tine, MD, PhD, Professor of Medicine, Washington University School of Medicine in a poster presentation at the 2023 CTOS Annual Meeting held November 1-4, 2023 in Dublin, Ireland.

Externally Funded Annamycin Trial 

A Phase 1B/2 investigator sponsored trial (externally funded) was initiated in Poland in 2022 to study an alternative dosing regimen for Annamycin in the treatment of STS lung mets. This trial has enrolled and begun treatment with subjects in the Phase 1B portion of the study. There will be 3 subjects per cohort with the first cohort treating subjects with 35 mg/m² of Annamycin per week (3 weeks on and 1 week off per cycle). After two cycles the subjects will receive their end of cycle 2 scan. At the end of two cycles both subjects treated to date demonstrated progressive disease. Preclinical data demonstrated a benefit to weekly dosing of Annamycin versus traditional chemotherapy dosing of every three weeks. We expect a detailed update on this trial in early 2024.

Publication of Data from Successful European Phase 1 Trial Evaluating Annamycin as Single Agent Treatment of Relapsed or Refractory AML

On July 13, 2023, we announced the publication of data from our completed MB-105 European Phase 1 clinical trial assessing the safety and efficacy of Annamycin as a single agent for the treatment of adults with relapsed or refractory AML. The manuscript titled, “Results of a Phase 1 Study of Liposomal Annamycin for the Treatment of Relapsed or Refractory AML Patients After Induction Therapy,” was published in the peer-reviewed British Journal of Cancer Research.

AACR Annamycin Presentation

We announced in April 2023 a presentation at the American Association for Cancer Research (AACR) Annual Meeting 2023 of positive pharmacokinetics and tissue-organ distribution data demonstrating high antitumor activity of Annamycin in preclinical cancer models, such data was based on research sponsored by us. In this research, Annamycin demonstrated increased penetration and accumulation in the liver, which correlated with high antitumor activity in HEPA 1-6 hepatocellular carcinoma and CT26 colon cancer liver metastasis models. This poster was presented at the AACR Annual Meeting 2023, which took place April 14-19, 2023, at the Orange County Convention Center in Orlando, FL. The poster titled, Exploration of Annamycin Organotropism to Target Primary and Metastatic Liver Cancers was presented by Rafal Zielinski, Ph.D., Department of Experimental Therapeutics, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center as part of the Experimental and Molecular Therapeutic Session: “Novel Antitumor Agents, PI3K/AKT Inhibitors, Proteasome Inhibitors, and Topoisomerases.” The poster outlined results from the analysis of the pharmacokinetics of two formulations of Annamycin, liposome formulated drug product (L-ANN) and free Annamycin (ANN), in the liver in comparison with doxorubicin (DOX) and to determine its tumoricidal potential in a hepatocellular carcinoma (HCC) model in situ and in experimental models of liver metastasis.

During the June 2023 meeting of the IV World Congress of Polish Physicians in Olsztyn, Poland. Dr. Waldemar Priebe, Chair of our Science Advisory Board was invited to lecture. He presented the above referenced AACR presentation “Discovery and Development of Novel Organotropic Anticancer Therapies”.

Licensing

WPD Licensing Agreement

Since February 2019, we were party to a sublicense agreement with WPD Pharmaceuticals (WPD), pursuant to which we sublicensed to WPD certain intellectual property rights, including rights to Annamycin, our WP1122 portfolio, and our WP1066 portfolio (as amended, the “WPD Agreement”). WPD is affiliated with Dr. Waldemar Priebe, our founder. In March 2023, we and WPD agreed to terminate the WPD Agreement. Pursuant to the termination, we agreed to pay WPD (or its designee) $700,000 in cash and shares of our common stock valued at $800,000. In March 2023, we issued 822,115 shares of common stock to WPD's designee as part of the satisfaction of this commitment. With the termination of the WPD Agreement, we now have acquired the rights in certain territories previously sub-licensed to WPD to all of our licensed intellectual property, other than the rights related to non-human animals. Additionally, we acquired the in-process research and development that WPD has created during the term of the agreement. As part of this Agreement, WPD assigned their rights and duties to us for the Phase 1B/2 investigator sponsored trial (externally funded) initiated in Poland in 2022 to study an alternative dosing regimen for Annamycin in the treatment of STS lung mets.

Liquidity and Capital Resources

The following table sets forth our primary sources and uses of cash for the period indicated (table in thousands): 

As of September 30, 2023,March 31, 2024, there was $0.3$0.4 million of cash on hand in a bank account in Australia and we know of no related limitations impacting our liquidity in Australia.

Cash used in operating activities

Cash used in operations was $18.76.7 million for the ninethree months ended September 30, 2023March 31, 2024. This $1.70.7 million decreaseincrease over the prior year period of $20.46.0 million was primarily due to an overall decrease in expenses, as well as license rights settled in stock.the timing of costs incurred and associated payments for drug production and clinical trial expenses. 

Cash provided by financing activities 

DuringWe did not sell any stock during the ninethree months ended September 30, 2023, utilizing the Lincoln Park Equity Line, we issueMarch 31, 2024d 225,568 shares of common stock (including commitment shares), at an average price of $0.94 per share, resulting in gross proceeds of $0.2 million.. 

We believe that our existing cash and cash equivalents as of September 30, 2023March 31, 2024 will be sufficient to fund our planned operations, which include our current Phase 1B/2 clinical programs and preparations for future clinical trials, into the thirdfourth quarter of 2024, without the issuance of additional equity for cash. This takes into account cash outlays for preparations for clinical trials beyond the current active trials. The continuation of our Company as a going concern is dependent upon our ability to obtain necessary equity financing to continue operations and the attainment of profitable operations. We may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. We cannot be certainprovide assurance that such events or a combination thereof can be achieved. 

In March 2022, we received a subpoena from the SEC requesting information and documents, including materials related to certain individuals (none of which are our officers or directors) and entities, and materials related to the development of and statements regarding our drug candidate for the treatment of COVID-19. We have received, and expect to continue to receive, periodic further requests from the SEC staff with respect to this matter. We are not aware of the specific nature of the underlying investigation by the SEC, and to the extent that this investigation relates to prior public disclosures that we have made, we believe in the accuracy and adequacy of such prior disclosures. The correspondence from the SEC transmitting the subpoena to us states that the SEC is trying to determine whether there have been any violations of federal securities laws, but that its investigation does not mean that the SEC has concluded that anyone has violated the law or that the SEC has a negative opinion of any person, entity, or security. We cannot predict when this matter will be resolved or what, if any, action the SEC may take following the conclusion of the investigation. We expensed approximately $0.4$0.1 million and $1.1$0.5 million in related general and administrative fees and expenses for the three months ended September 30,March 31, 2024 and 2023 and 2022, respectively and $1.4 million and $1.9 million for the nine months ended September 30, 2023 and 2022, respectively..

We must comply with indirect tax laws in multiple jurisdictions, as well as complex customs duty regimes worldwide. Audits of our compliance with these rules may result in additional liabilities for taxes, duties, interest and penalties related to our international operations which would reduce our profitability.

Our operations may be subject to audit by tax authorities in various countries. Many countries have indirect tax systems where the sale and purchase of goods and services are subject to tax based on the transaction value. These taxes are commonly referred to as value-added tax (“VAT”) or goods and services tax (“GST”). In addition, the distribution of our products subjects us to numerous complex customs regulations, which frequently change over time. Failure to comply with these systems and regulations can result in the assessment of additional taxes, duties, interest, and penalties. While we believe we are in compliance with local laws, we cannot assure that tax and customs authorities will agree with our reporting positions and upon audit such tax and customs authorities may assess additional taxes, duties, interest, and penalties against us. Adverse action by any government agencies related to indirect tax laws could materially and adversely affect our business, results of operations and financial condition.

Errors in our assumptions, estimates and judgments related to tax matters, including those resulting from regulatory reviews, could adversely affect our financial results.

We may be subject to routine tax audits on various tax matters around the world in the ordinary course of business (including income tax, business tax, customs duties, sales and use tax, and value added tax (“VAT”) matters). We regularly assess the adequacy of our uncertain income tax positions and other reserves, which requires a significant amount of judgment. Although we may accrue for uncertain income tax positions and other regulatory audits, negotiations with taxing and customs authorities may lead to adjustments in excess of our accruals, resulting in liabilities for additional taxes, duties, penalties and interest.
