Furthermore, we cannot guarantee future results, events, levels of activity, performance, or achievements. 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 been permitted to proceed in, thirteen 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. 13 Table of Contents Our Core Technologies Our core technologies consist of the following programs: a) Annamycin or L-Annamycin is a “next generation” anthracycline (one of the most widely 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. As of March 2024, Annamycin demonstrated efficacy in two of its Phase 1B/2 trials in subjects with AML and Advanced STS. We believe that Annamycin has potential to fill an unmet need as a second line therapy (2nd line or 2L) in AML and potentially as first line therapy in Advanced STS. As part of our Annamycin clinical trials, we have engaged an independent expert to assess cardiotoxicity associated with chemotherapy at the Cleveland Clinic (Expert or Independent Expert). The data made available to the Expert includes left ventricular ejection fraction (LVEF) as determined by echocardiograms, and ECHO strain imaging, as well as Troponin 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. 14 Table of Contents Recent Business Developments Below are recent business developments. Annamycin Clinical Trial for the Treatment of AML in Combination with Cytarabine (MB-106) Table 1 Study MB-106 Combination Therapy – Phase 1B/2 with Ara-C + Annamycin "5+3" All Lines (Range 1-7) 1st Line 2nd Line All Subjects Recruited and Evaluable 20 3 10 Subjects Evaluable Not Dosed Per Protocol 2 0 1 Median Age - Years (Range) 69 (19 - 78) 49 (19 - 69) 71 (53 - 78) Complete Remissions (CR) 8 2 5 CR with incomplete recovery (CRi) 1 0 1 Total Composite Complete Remission (CRc) 9 2 6 Complete Remission (CR) Rate 40% 67% 50% Complete Remission Composite (CRc) Rate 45% 67% 60% Partial Remission (PRs) 2 0 1 Overall Response Rate (CRc's + PRs) or ORR 55% 67% 70% CRc Relapsed or Death To Date 2 0 2 BMT to Date (in CR's) 2 0 1 See Note 1 below 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 7, 2024, our management held a Key Opinion Leader conference call with Dr. Martin Tallman and Dr. Michael Andreeff. Management made a presentation of the data 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 trial has been successful in establishing safety and efficacy of Annamycin in combination with Cytarabine (AnnAraC) for the treatment of AML, and in providing sufficient data to support a Phase 2 registration-directed clinical trial (MB-108) to further provide data for efficacy which we intend to use to support an eventual application for New Drug Approval (NDA). Preliminary Safety, Efficacy and Durability Data The preliminary data for MB-106 demonstrate a CRc rate of 45% and an ORR of 55% for all subjects, regardless of the number of prior treatments (N=20). Segmenting the MB-106 subject population for 1 st line (N=3) and, most notably, 2 nd line (N=10) therapies in the trial, 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 pneumonia) and one relapse to date out of the ten 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 of treatment to relapse or death. Cardiovascular safety of Annamycin is 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 across five trials (AML & STS, internal and externally funded trials) have been reviewed. Of note, most of these subjects have received greater than the lifetime cumulative anthracycline dose above 550 mg/m2 associated with increased risk of cardiomyopathy. Some subjects have received four times this amount following Annamycin administration(s). No signal of cardiotoxicity has been identified. 15 Table of Contents U.S Patents for Annamycin On 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 received an Issue Notification from the USPTO for an additional patent (U.S. Patent number 11,980,634) titled “ Method of Reconstituting Liposomal Annamycin ” (the ‘634 patent’) to be issued on May 14, 2024. The ‘118 patent provides claims to compositions that contain Annamycin, and the ‘634 patent, when issued, will provide claims to liposomal Annamycin suspension 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 (STS lung mets) uses a unique lipid-based delivery technology. In addition to the issued ‘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 AML We announced that the European Medicines Agency (EMA) has granted Orphan Drug Designation (ODD) to Annamycin for the treatment of AML. Combined with the Orphan Drug Designation we have in the US and with the new composition of matter and formulation patents just awarded by the US Patent and Trademark Office with coverage through 2040, we believe the commercial exclusivity of Annamycin is now well protected. The EMA grants orphan drug designation to drugs and biologics intended for the treatment, diagnosis or prevention of rare, life-threatening or chronically debilitating diseases or conditions that affect fewer than five in 10,000 people in the European Union. Orphan designation potentially allows companies certain benefits, including reduced regulatory fees, clinical protocol assistance, research grants and up to 10 years of potential market exclusivity in the European Union if approved. AACR Presentation of Data Demonstrating High Anti-Cancer Activity of Annamycin and Non-Cardiotoxic Properties Preclinical data regarding the Company’s next-generation anthracycline, Annamycin, was presented at the American Association for Cancer Research (AACR) Annual Meeting, which took place April 5-10, 2024 in San Diego, CA. The poster titled, Non-cardiotoxic Properties of Annamycin, a Clinically Evaluated Anthracycline and Potent Topoisomerase 2β Poison, was presented in the “Late-Breaking Research: Experimental and Molecular Therapeutics 2” session held on Monday, April 8 th . The presented poster outlined results from the assessment and comparison of the potency of doxorubicin (a commonly prescribed anthracycline) and Annamycin, Moleculin’s next-generation anthracycline, against topoisomerase II-alpha and II-beta and determine their impact on physiology of human cardiomyocytes demonstrating no pathologic changes in mice hearts following chronic in vivo exposure. 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. Of note, we have finalized an agreement with Northwestern University (NU) and we expect NU to initiate an investigator initiated glioblastoma study in the near-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 believe that substantial progress has been made and we will be able to announce an IV formulation in the near 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. 16 Table of Contents Results of Operations The following table sets forth, for the periods indicated, data derived from our statement of operations (table in thousands) and such changes in the periods are discussed below in approximate amounts: Moleculin Biotech, Inc. Condensed Consolidated Statements of Operations (Unaudited) Three Months Ended March 31, 2024 2023 Revenues $ — $ — Operating expenses: Research and development 4,252 5,687 General and administrative 2,393 2,637 Depreciation and amortization 32 30 Total operating expenses 6,677 8,354 Loss from operations (6,677 ) (8,354 ) Other income: Gain from change in fair value of warrant liability 1,455 39 Other income, net 11 8 Interest income, net 241 392 Net loss $ (4,970 ) $ (7,915 ) Three Months Ended March 31, 2024 Compared to Three Months Ended March 31, 2023 Research and Development Expense. Research and development (R&D) expense was $4.3 million and $5.7 million for the three months ended March 31, 2024 and 2023 , respectively. The decrease of $1.4 million is mainly related t o the clinical trials activity levels. General and Administrative Expense. General and administrative e xpense was $2.4 million and $2.6 million for the three months ended March 31, 2024 and 2023 , respectively. The decrease of $0.2 million is mainly related to a decrease in regulatory and legal fees. Gain from Change in Fair Value of Warrant Liability. We recorded a net gain of $1.5 million in the first quarter of 2024 as compared to a net gain of $0.04 million in the first quarter of 2023, for the change in fair value on revaluation of our warrant liability associated with our warrants issued in conjunction with certain of our previous stock offerings. We are required to revalue our liability-classified warrants at the time of each warrant exercise, if applicable, and at the end of each reporting period and reflect in the statement of operations a gain or loss from the change in fair value of the warrant in the period in which the change occurred. We calculated the fair value of the warrants outstanding using the Black-Scholes model. A gain results principally from a decline in our share price during the period and a loss results principally from an increase in our share price. Interest income, net. Interest income, ne t decreased by approximately $0.2 million f or the comparable quarterly periods due to a decreasing cash balance during the past year. 17 Table of Contents Liquidity and Capital Resources The following table sets forth our primary sources and uses of cash for the period indicated (table in thousands): Three Months Ended March 31, 2024 2023 Net cash used in operating activities $ (6,717 ) $ (6,017 ) Net cash provided by financing activities — 141 Effect of exchange rate changes on cash and cash equivalents (9 ) (4 ) Net decrease in cash and cash equivalents $ (6,726 ) $ (5,880 ) As of March 31, 2024, there w as $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 $6.7 million for the three months ended March 31, 2024 . This $0.7 million increase over the prior year period of $6.0 million was primarily due to the timing of costs incurred and associated payments for drug production and clinical trial expenses. Cash provided by fin ancing activities We did not sell any stock during the three months ended March 31, 2024 . We believe that our existing cash and cash equivalents as of March 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 fourth 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 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 provide 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 approximate ly $0.1 million and $0.5 million in related general and administrative fees and expenses for the three months ended March 31, 2024 and 2023 , respectively . Critical Accounting Policies and Significant Judgments and Estimates There have been no material changes to our critical accounting policies and use of estimates from those disclosed in our Form 10-K for the year ended December 31, 2023. For a discussion of our critical accounting policies and use of estimates, refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Significant Estimates in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2023. 18 Table of Contents ITEM 3.
