The FDA added three months to its review after requesting information on possible safety measures for Agios' sickle cell drug.
Agios Pharmaceuticals (AGIO) announced a three-month extension in the FDA review of its sickle cell disease drug, mitapivat, due to additional information requested on safety measures. The new PDUFA goal date is February 1, 2027, pushed back from November 1, 2026. The FDA classified Agios' response as a major amendment, requiring further review. Mitapivat is currently approved for other anemias and is being evaluated under the FDA's accelerated approval pathway.
