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 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.

2 Interventions

Name: AG-348

Description: Part 1 (Dose Optimization Period): Participants will begin by receiving 5 milligrams (mg) orally, twice a day. Each participant's dose of AG-348 may be increased to 20 mg twice a day or 50 mg twice a day depending on their response to AG-348 and their tolerance. Part 2 (Fixed Dose Period): Last dose received in Part 1, twice daily.

Type: Drug

AG-348

Name: Placebo

Description: Part 1 (Dose Optimization Period): Participants will begin by receiving placebo matching AG-348 orally, twice a day. Each participant's dose of placebo matching AG-348 may be increased to 20 mg twice a day or 50 mg twice a day depending on their response to the placebo matching AG-348 and their tolerance. Part 2 (Fixed Dose Period): Last dose received in Part 1, twice daily.

Type: Drug

Placebo
