On 2 October 2025, the U.S. Food and Drug Administration granted Fast Track designation to BMS‑986446, an anti‑tau antibody in Phase 2 development for Alzheimer’s disease. The designation was announced by Bristol Myers Squibb, a strategic partner of Prothena, and is intended to expedite the review process for this program.
BMS‑986446 targets the microtubule‑binding region of tau protein, a key driver of neurodegeneration in Alzheimer’s disease. The Fast Track status allows for more frequent interactions with the FDA, potential rolling review of data, and priority review if the program meets the criteria for accelerated approval. These regulatory advantages can shorten the time to market and reduce development costs for the partnered asset.
For Prothena, the Fast Track designation enhances the value of its partnered pipeline and signals confidence from a major industry partner. It also improves the company’s strategic positioning in the competitive Alzheimer’s therapeutic landscape, potentially increasing investor interest and supporting future collaboration opportunities.
