Study AG348-C-007 is a multicenter study designed to evaluate the efficacy and safety of treatment with AG-348 in a minimum of 20, with up to 40, subjects with pyruvate kinase deficiency (PKD), who are regularly receiving blood transfusions. The study is comprised of two parts. During the Part 1 Dose Optimization Period of the study, all participants will start on a dose of 5 mg AG-348 administered twice daily. Over the course of Part 1 each participant's dose will be optimized individually, up to a maximum dose of 50 milligrams (mg), twice daily. During the Part 2 Fixed-Dose Period, participants will receive AG-348 at their optimized dose from Part 1.
