Portfolio Pulse from Benzinga Newsdesk
The FDA has determined that Actinium Pharmaceuticals' Phase 3 Sierra Trial is not adequate to support a BLA filing for Iomab-B for relapsed or refractory acute myeloid leukemia, despite achieving its primary endpoint. Actinium will need to conduct an additional head-to-head randomized clinical trial to demonstrate overall survival benefit. The company plans to request a meeting with the FDA to discuss the specifics and will seek a strategic partner for Iomab-B in the U.S. Actinium will also focus on developing Actimab-A, Iomab-ACT, and preclinical programs.
