Mitapivat's November 1 sickle cell decision follows a hemoglobin win and a pain-crisis miss

Agios is a commercial-stage company whose drug mitapivat is approved for thalassemia and is under FDA review for sickle cell disease.

Mitapivat is approved for thalassemia in the US, EU, Saudi Arabia and UAE, and worldwide sales reached $44.7 million in Q2 2026. In sickle cell disease, Phase 3 RISE UP improved hemoglobin but missed statistical significance on pain crises, so FDA's November 1 accelerated-approval decision is the key test. If approved, the confirmatory REIGNITE trial must show that mitapivat reduces transfusion burden.
