Numerous clinical trials spanning Phase 1 through Phase 3 evaluate Mitapivat across various hereditary erythrocyte disorders and associated complications, including pyruvate kinase deficiency, pediatric hemolytic anemia, sickle cell disease, alpha- and beta-thalassemia, and moderate hepatic impairment. Sponsored by industry entities such as Agios Pharmaceuticals Inc. alongside major research institutions like the National Heart, Lung, and Blood Institute and EuroBloodNet Association, these protocols demonstrate recruitment statuses ranging from actively recruiting and completed to active, not recruiting and withdrawn.
