Moleculin Biotech's Annamycin Advances to Phase 3 Trial for Relapsed/Refractory AML
核心洞察
Moleculin Biotech's Annamycin receives IRB approval to begin a Phase 3 clinical trial (MIRACLE) for relapsed or refractory AML (搜索).
The MIRACLE trial will evaluate Annamycin in combination with cytarabine, with potential for accelerated FDA approval.
The adaptive trial design will optimize Annamycin dosage based on safety, pharmacokinetics, and efficacy data from initial subjects.
Moleculin Biotech has received Institutional Review Board (IRB) approval to proceed with its Phase 3 pivotal trial, known as the MIRACLE trial, evaluating Annamycin in combination with cytarabine (Ara-C) for patients with relapsed or refractory acute myeloid leukemia (搜索) (R/R AML (搜索)). The study, titled "Moleculin R/R AML AnnAraC Clinical Evaluation," is designed as a global trial with sites in the US, and aims for potential accelerated approval of Annamycin.
Walter Klemp, Chairman and CEO of Moleculin, stated, "IRB approval marks an important milestone towards the launch of our MIRACLE pivotal Phase 3 trial of Annamycin in AML (搜索) patients. Our team is focused on getting clinical trial sites up and running, and we believe we will be in a position to commence enrollment in the first quarter of 2025."
Trial Design
The MIRACLE trial will employ an adaptive design. The initial phase (Part A) will randomize 75 to 90 subjects to receive high-dose cytarabine (HiDAC) combined with either placebo, 190 mg/m2 of Annamycin, or 230 mg/m2 of Annamycin. The doses were specifically recommended by the FDA during the end of Phase 1B/2 meeting. Following unblinding, the optimal Annamycin dose will be selected based on safety, pharmacokinetics, and efficacy, aligning with the FDA's Project Optimus initiative.
Part B of the trial will involve approximately 240 additional subjects randomized to receive either HiDAC plus placebo or HiDAC plus the optimized dose of Annamycin.
Regulatory Status and Background
Annamycin has been granted Fast Track Status and Orphan Drug Designation by the FDA for R/R AML (搜索), along with Orphan Drug Designation for soft tissue sarcoma (搜索). It also holds Orphan Drug Designation from the European Medicines Agency (EMA) for R/R AML. Annamycin is a next-generation anthracycline designed to overcome multidrug resistance mechanisms and reduce cardiotoxicity associated with traditional anthracyclines.
