Transfusion-dependent (TD) high cohort: transfusion independence (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the absence of packed red blood cell (PRBC) transfusions over any rolling 12-week interval during the treatment period with a minimum hemoglobin (Hgb) of 7 g/dL. Participants meeting this criterion will be considered to have a major response to treatment.

TD low cohort: transfusion independence (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the absence of PRBC transfusions over any rolling 16-week interval during the treatment period with a minimum Hgb of 7 g/dL. Participants meeting this criterion will be considered to have a major response to treatment.

Non-transfusion-dependent (nTD) cohort: anemia response (Phase 2 only)
From Day 1 to the end of treatment on Day 169

Defined as the composite of the absence of transfusions over any rolling 12-week period and a concomitant mean Hgb increase of ≥1.5 g/dL over baseline. Participants meeting this criterion will be considered to have a major response to treatment.
