Agios Provides Update on U.S. PDUFA Goal Date for PYRUKYND® (mitapivat) in Thalassemia

Core Viewpoint - The U.S. FDA has extended the PDUFA goal date for Agios Pharmaceuticals' supplemental New Drug Application (sNDA) for PYRUKYND from September 7, 2025, to December 7, 2025, due to a proposed Risk Evaluation and Mitigation Strategy (REMS) submission to address hepatocellular injury risks [1][2]. Company Overview - Agios Pharmaceuticals is a commercial-stage biopharmaceutical company focused on innovative medicines for rare diseases, headquartered in Cambridge, Massachusetts [17]. Product Information - PYRUKYND (mitapivat) is an oral pyruvate kinase activator indicated for treating adult patients with non-transfusion-dependent and transfusion-dependent alpha- or beta-thalassemia [1][10]. - The sNDA for PYRUKYND is supported by results from the global, randomized, double-blind, placebo-controlled ENERGIZE and ENERGIZE-T Phase 3 trials [3][6]. Clinical Trials - The ENERGIZE trial involved 194 non-transfusion-dependent patients, with a primary endpoint of achieving a hemoglobin response defined as an increase of ≥1.0 g/dL in average hemoglobin concentrations [7]. - The ENERGIZE-T trial included 258 transfusion-dependent patients, focusing on achieving a transfusion reduction response defined as a ≥50% reduction in transfused red blood cell units [8]. Disease Context - Thalassemia is a rare inherited blood disease affecting hemoglobin production, categorized into alpha-thalassemia and beta-thalassemia, leading to anemia and serious complications [4][5]. - Approximately 6,000 adult patients in the U.S. are diagnosed with thalassemia, experiencing significant disease burden and reduced quality of life [5].
