Mitapivat sulfateProduct ingredient for Mitapivat

Mitapivat is a novel, first-in-class pyruvate kinase activator. It works to increase the activity of erythrocyte pyruvate kinase, a key enzyme involved in the survival of red blood cells. Defects in the pyruvate kinase enzyme in various red blood cells disorders lead to the lack of energy production for red blood cells, leading to lifelong premature destruction of red blood cells or chronic hemolytic anemia.¹

On February 17, 2022, the FDA approved mitapivat as the first disease-modifying treatment for hemolytic anemia in adults with pyruvate kinase (PK) deficiency, a rare, inherited disorder leading to lifelong hemolytic anemia.⁶ Mitapivat has also been investigated in other hereditary red blood cell disorders associated with hemolytic anemia, such as sickle cell disease and alpha- and beta-thalassemia.¹ On January 5, 2026, the FDA also approved the use of in the treatment of anemia in adults with alpha- or beta-thalassemia, making it the first oral treatment for this condition.⁷
