PK Deficiency
Data to be presented highlight that long-term treatment with PYRUKYND (mitapivat) in adults with PK deficiency is associated with sustained clinical benefits, including improvements in hemoglobin, iron overload, and decreased burden of disease on work and school activities.

Thalassemia
Data for PYRUKYND in adults with beta-thalassemia show evidence of reduced oxidative stress in red blood cells, as well as enhanced PK activity and metabolic reprogramming. Additionally, qualitative data demonstrate the equally common burden of disease across alpha- and beta-thalassemia patients, regardless of transfusion dependency.
