1 A Phase 3, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of AG-348 in Not Regularly Transfused Adult Subjects With Pyruvate Kinase Deficiency

Study AG348-C-006 will evaluate the efficacy and safety of orally administered AG-348 as compared with placebo in participants with pyruvate kinase deficiency (PKD), who are not regularly receiving blood transfusions. Participants will be randomized 1:1 to receive either AG-348 or matching placebo. The study is comprised of two parts. During the Part 1 Dose Optimization Period of the study, participants will start on a dose of 5 mg AG-348 administered twice daily. Over the course of Part 1, each participant's dose of AG-348 may be sequentially increased to 20 mg twice a day, followed by 50 mg twice a day depending on their tolerance. During the Part 2 Fixed-Dose Period, participants will receive AG-348 at their optimized dose from Part 1.

2 An Open-Label Study To Evaluate the Efficacy and Safety of AG-348 in Regularly Transfused Adult Subjects With Pyruvate Kinase (PK) Deficiency

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.
