Mitapivat (AG-348; PKM2 activator 1020) is a novel, first-in-class oral small molecule allosteric activator of the pyruvate kinase enzyme. Mitapivat has been shown to significantly upregulate both wild-type and numerous mutant forms of erythrocyte pyruvate kinase (PKR), increasing adenosine triphosphate (ATP) production and reducing levels of 2,3-diphosphoglycerate. Given this mechanism, mitapivat has been evaluated in clinical trials in a wide range of hereditary hemolytic anemias, including pyruvate kinase deficiency (PKD), sickle cell disease, and the thalassemias. Mitapivat was approved for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency in the United States in February 2022, and in the European Union in November 2022.

Sample Use Guides

The starting dosage for PYRUKYND is 5 mg orally twice daily. To gradually increase hemoglobin (Hb), titrate PYRUKYND from 5 mg twice daily to 20 mg twice daily, and then to the maximum recommended dose of 50 mg twice daily, with these dose increases occurring every 4 weeks
Route of Administration: Oral
In human red blood cells, mitapivat activates PKR with AC50 and AC90 for PKR activation of 0.0619±0.0346 uM and 1.002±1.109 uM, respectively. The average maximum percent PKR activation was 274%±56%. It was demonstrated that while the WT PKR was activated by mitapivat with AC50 0.013 uM the 10 mutant PKR isoforms evaluated were activated with AC50 values ranged approximately 0.009 to 0.059 uM.
