Clinical Trials
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.

- Splenectomy scheduled during the study treatment period or have undergone splenectomy
within 12 months prior to signing informed consent;

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.
