Dosing is complete for 90 people in a leukemia trial.
Moleculin Biotech (MBRX) completed dosing for 90 patients in Part A of its Phase 2/3 MIRACLE trial for Annamycin in treating relapsed or refractory acute myeloid leukemia (AML). The company expects to report comprehensive data in Q1 2027, which will support dose selection for Part B. Annamycin is designed to avoid multidrug resistance and lacks cardiotoxicity common with other treatments.
