Official title

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

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Study AG348-C-007 was a multicenter study designed to evaluate the efficacy and safety of treatment with AG-348 in a minimum of 20, with up to 40, participants with pyruvate kinase (PK) deficiency, who were regularly receiving blood transfusions. The study was composed of two parts. During Part 1, Dose Optimization Period, participants started on a dose of 5 mg AG-348 administered twice daily. Over the course of Part 1 each participant's dose of AG-348 was sequentially increased to 20 mg twice a day, followed by 50 mg twice a day depending on their tolerance. During Part 2, Fixed-Dose Period, participants received AG-348 at their optimized dose from Part 1.
