About MBRX
Moleculin Biotech, Inc. 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. Its core technologies consist of Annamycin, WP1066 Portfolio, and WP1122 Portfolio. Annamycin is designed to avoid multidrug resistance mechanisms and cardiotoxicity. Its WP1066, is an Immune/Transcription Modulator capable of inhibiting p-STAT3 and other transcription factors, and its portfolio includes WP1193, and WP1220. Its WP1122 contains compounds including WP1096, and WP1097, which is designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (2-DG).

Moleculin Biotech Advances Cardiac Safety Profile in Annamycin Trials
- Cardiac Safety Data: At the 2026 ASCO Annual Meeting, Moleculin Biotech presented data showing that Annamycin, administered at a median cumulative dose of 660 mg/m² to 90 patients with acute myeloid leukemia, demonstrated no detectable cardiotoxicity, indicating a potential best-in-class safety profile.
- Clinical Trial Support: The independent review conducted by Cleveland Clinic cardiology specialists further validated Annamycin's safety at high doses, suggesting a shift in traditional treatment limitations and enhancing its application prospects in oncology.
- Efficacy Data Highlights: In a Phase 1b/2 study evaluating Annamycin in combination with cytarabine, the drug exhibited a 50% complete remission rate and a 60% composite remission rate, underscoring its effectiveness in treating relapsed or refractory acute myeloid leukemia.
- Future Research Directions: Moleculin's ongoing pivotal Phase 2b/3 MIRACLE trial will further assess the combination of Annamycin and cytarabine, with unblinding expected in June 2026; positive results could establish a strong foundation for market introduction.

Moleculin Biotech Reveals Cardiac Safety Data for Annamycin
- Cardiac Safety Analysis: Analysis of 90 patients across five clinical trials shows that Annamycin does not induce clinically significant cardiotoxicity at high cumulative doses, indicating its potential in treating relapsed/refractory acute myeloid leukemia (R/R AML).
- Stable Left Ventricular Function: Among 78 verified patients, pre- and post-treatment ejection fraction assessments revealed no patients met criteria for clinically significant left ventricular dysfunction, with mean ejection fraction remaining stable, underscoring Annamycin's safety profile.
- Overcoming Treatment Barriers: The cardiac safety data reinforces Annamycin's clinical rationale as a differentiated anthracycline capable of overcoming the cardiac toxicity limitations of traditional agents in R/R AML, thus providing new treatment options for heavily pretreated patients.
- Future Clinical Positioning: Moleculin Biotech believes that the results published at EHA may support broader clinical positioning opportunities for Annamycin in AML and other oncology indications, particularly where cardiotoxicity concerns limit the use of anthracyclines.
