Moleculin Biotech announced the publication of preclinical data demonstrating the significant activity of Annamycin in treating venetoclax-resistant acute myeloid leukemia (AML) cell lines. The study, presented at the American Society of Hematology Annual Meeting, revealed that Annamycin effectively targets both Cytarabine (Ara-C) and Venetoclax resistant AML cell lines from heavily pretreated relapsed/refractory primary AML patients in vitro.
The data showed Annamycin's synergy with Ara-C and Venetoclax in reducing cell viability, a lack of cardiotoxicity, improved organotropism, and potential immune-memory reinforcing properties. These findings correlate with preliminary clinical data showing a 60% composite complete remission (CRc) rate in subjects using Annamycin and Ara-C (AnnAraC) as a second-line treatment.
Annamycin's favorable toxicity profile, as compared to DOX, and its ability to extend survival in combination with Ara-C, underscore its potential as a breakthrough treatment. Moleculin is advancing Annamycin in a Phase 3 trial, 'MIRACLE,' set to begin patient treatment in Q1 2025. Annamycin has Fast Track Status and Orphan Drug Designation from the FDA and EMA.
