| Secondary | Part 1: Number of Participants Who Were Transfusion-free | The number of participants who did not receive any transfusions (packed red blood cells [pRBCs] or whole blood) during the period of interest were reported. Participants who were transfusion free were defined for each treatment group as the number of participants who did not receive any transfusions (pRBCs or whole blood) during the period of interest from the start to the end, inclusive, divided by the total number of participants in that treatment group at the start of the period of interest. Participants who (1) discontinued treatment prior to Week 24, or (2) did not receive a transfusion during the period of interest despite recording a hemoglobin (Hb) value ≤ 9 g/dL with symptoms assessed by the investigator as warranting transfusion or a Hb value ≤ 7 g/dL regardless of symptoms were not considered transfusion free. | Participants in the ASaT population in Part 1 were analyzed. | Posted | | Count of Participants | | Participants | | From Week 4 to Week 24 | | | | ID | Title | Description |

| Secondary | Part 1: Percentage (%) Reduction in the Rate of pRBC Units Transfused | The rate of pRBC units transfused from Week 4 to Week 24 was calculated and compared to the rate of pRBC units transfused prestudy during the 12 months prior to screening. The percent reduction in rate of pRBC units transfused was the percent difference in rate relative to the prestudy rate, calculated as: (current rate - prestudy rate)/prestudy rate * 100%.
