Study Endpoints
Primary Endpoints
Percentage of Participants Achieving a Hemoglobin Response (HR)
Up to 12 weeks

HR was defined as a ≥1.0 gram per deciliter (g/dL) increase in Hb concentration from Baseline at 1 or more assessments between Week 4 and Week 12 (inclusive). A participant's Baseline Hb concentration was defined as the average of all the participant's available Hb concentrations during the screening period up to the first dose of study drug.

Secondary Endpoints
Average Change From Baseline in Hb Concentrations From Week 12 to Week 24
Baseline, Week 12 to Week 24
Percentage of Participants Achieving a Sustained Hb Response (sHR)
Week 12 to Week 24
Percentage of Participants Achieving a Delayed Hb Response

AG-348EXPERIMENTALParticipants with alpha or beta thalassemia received AG-348 50 mg twice daily (BID), orally up to Week 6. Following Week 6, depending on the participants' safety and hemoglobin (Hb) concentrations, they could undergo one potential dose-level increase from 50 to 100 mg BID. After completion of the Core Period of 24 weeks, participants were eligible to continue to receive AG-348 in the Extension Period which is up to 10 years.
