FDA pushes Agios’ sickle‑cell mitapivat decision to Feb 1 2027

The U.S. FDA extended the PDUFA goal date for Agios Pharmaceuticals’ supplemental NDA for mitapivat in sickle‑cell disease from November 1 2026 to February 1 2027. The agency classified Agios’ response to a request for REMS information as a major amendment, adding a three‑month review extension. Agios submitted about nine months of updated safety data on October 19 2026 and said it remains launch‑ready.

The delay caused Agios’ stock to fall about 18% as investors reassess the timing of the anticipated sickle‑cell launch. The later decision date also pushes back potential revenue from the largest indication for mitapivat.
