Moleculin Biotech, Inc. (NASDAQ: MBRX) is a Phase III clinical-stage pharmaceutical company advancing a pipeline of therapeutic candidates addressing tumors and viruses. The Company is conducting a pivotal Phase III trial evaluating Annamycin, a non-cardiotoxic anthracycline, in combination with Cytarabine for the treatment of subjects with relapsed/refractory acute myeloid leukemia (AML). It has three core technologies and six drug candidates, three of which have shown human activity in clinical trials. 

Financial Performance

• Clinical Advancements and Regulatory Milestones: Moleculin Biotech, Inc. reported significant progress with enrollment and dosing underway in its pivotal Phase 3 MIRACLE trial evaluating Annamycin (naxtarubicin) for relapsed or refractory (R/R) acute myeloid leukemia (AML). The company received a key European Medicines Agency (EMA) approval to expand the MIRACLE trial to nine additional EU countries—Belgium, Czechia, France, Germany, Italy, Lithuania, Poland, Romania, and Spain—following authorizations across all requested EU nations, with 38 sites selected globally (including 5 in the US) as of late April 2025, supporting an interim data readout expected in the second half of 2025. Additionally, Annamycin has received Fast Track Status and Orphan Drug Designation from the FDA for R/R AML and STS lung metastases, and EMA Orphan Drug Designation for R/R AML, while the World Health Organization approved “naxtarubicin” as its non-proprietary name, bolstering its intellectual property with two new U.S. patents.
• Pipeline Development and Future Prospects: Beyond AML, Moleculin is advancing its pipeline with promising developments, including the expected release of final data from the MB-107 trial for Annamycin in soft tissue sarcoma (STS) lung metastases by the end of June 2025, and ongoing investigator-initiated clinical and preclinical work on WP1066, a STAT3 inhibitor, with a Phase 1B/2 trial for glioblastoma at Northwestern University actively recruiting 7 subjects and preclinical studies at Emory University underway, with results anticipated in the second half of 2025. The MIRACLE trial’s adaptive design includes two unblindings—first at 45 subjects in H2 2025 and second at 75-90 subjects in H1 2026—to assess efficacy and safety, with patient dosing commenced and an accelerated timeline driven by positive investigator feedback, positioning the company for potential regulatory submissions starting in 2028. Strategic milestones, such as initiating a pediatric AML trial in 2027 and a rolling New Drug Application (NDA) for R/R AML in 2028, underscore Moleculin’s commitment to expanding its therapeutic reach.
• Financial Overview and Liquidity: Financially, Moleculin reported a Q1 2025 research and development expense of USD 3.4 million, down from USD 4.3 million in Q1 2024 due to reduced clinical trial activity, and a general and administrative expense of USD 2.5 million, up slightly from USD 2.4 million due to increased regulatory and legal fees, reflecting a focused cost structure. As of March 31, 2025, the company held cash and cash equivalents of USD 7.7 million, deemed sufficient to fund operations into the third quarter of 2025, despite ongoing losses.

On the technical front, Moleculin Biotech, Inc.'s (Nasdaq: MBRX) stock has endured a sustained downtrend since late 2024, characterized by elevated volatility and speculative activity.
