Sandesh Seth, Actinium’s Chairman and CEO, said, “We are disappointed that the positive results from the SIERRA trial are not deemed adequate by the FDA to support a BLA filing despite meeting the primary endpoint with statistical significance and producing positive efficacy and safety outcomes on several measures. SIERRA represented a first of its kind radiotherapeutic trial and demonstrated Actinium’s ability to execute seamlessly across manufacturing, supply chain, clinical development, and operations.

We are committed to establishing the best development path forward for Iomab-B in the U.S. and finding a partner, while keeping internal resources and strategic priorities in focus.”
