Outcome Measures
Primary Outcome Measures
- Mean Change in Hemoglobin (Hb) Levels From Pre-treatment to the End of the Primary Efficacy Period [Pre-treatment; Week 6]
The pre-treatment average value for Hb was defined as the average of 3 values obtained prior to treatment, i.e., the qualifying screening value and the Baseline value. Change from Pre-treatment was calculated as the Week 6 value minus the Pre-treatment value.
Secondary Outcome Measures
- Time to Reach the Target Hb Level of 10.0 to 12.0 g/dL From Baseline up to Week 16 [from Baseline up to Week 16]
Time for this analysis was measured from Day 1 (Baseline) through the point in time during either the Primary Efficacy Period or the Dose Adjustment and Maintenance Period when a participant's Hb level achieved the target range of 10.0 to 12.0 g/dL.
- Mean Hb Levels at the End of the Primary Efficacy Period [up to Week 6]
Data are reported as mean of the actual Week 6 values.
- Mean Hb Levels at the End of the Dose Adjustment and Maintenance Period [up to Week 16]

A pre-treatment average value for Hb was defined as the average of 3 values obtained prior to dosing, i.e., the 2 qualifying screening values and the Baseline value. Change from Pre-treatment was calculated as the Week 16 value minus the Pre-treatment value.
- Mean Change in Red Blood Cell (RBC) Count and Absolute Reticulocyte Count From Baseline to the End of the Primary Efficacy Period [Baseline; Week 6]
Change from Baseline was calculated as the post-Baseline value minus the Baseline value.

- Number of Participants Who Required Rescue With RBC Transfusion From Baseline to the End of the Dose Adjustment and Maintenance Period [Baseline; Week 16]
Participants who initiated rescue therapy (including RBC transfusion) were required to stop study drug treatment and were discontinued from the study.
- Number of Participants Who Required Rescue With Erythropoiesis-Stimulating Agents (ESAs) From Baseline to the End of the Primary Efficacy Period [Baseline; Week 6]
ESA rescue is defined as participants with ESA administration and 1) the participant experienced a clinically significant worsening of their anemia or symptoms of anemia, 2) the participant's Hb level is <9.0 g/dL, and 3) reason for early study withdrawal of worsening of anemia requiring ESA rescue or blood transfusion.

An AE included medical conditions, signs, and symptoms not previously observed in the participant that emerged during the protocol-specified AE reporting period, including signs or symptoms associated with pre-existing underlying conditions that were not present prior to the AE reporting period. An AE that met one or more of the following criteria or outcomes was classified as serious: death; life-threatening; in-patient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect; was considered a medically important event not meeting the above criteria, but which could jeopardize a participant, or could require medical or surgical intervention to prevent one of the criteria listed in this definition.

Title | Mean Change in Hb Between Pre-treatment and the End of the Dose Adjustment and Maintenance Period |
---|---|
Description | A pre-treatment average value for Hb was defined as the average of 3 values obtained prior to dosing, i.e., the 2 qualifying screening values and the Baseline value. Change from Pre-treatment was calculated as the Week 16 value minus the Pre-treatment value. |
Time Frame | Pre-treatment; Week 16 |

Title | Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (SAEs) in the Primary Efficacy Period |
---|---|
Description | An adverse event (AE) was defined as any untoward medical occurrence (including a clinically significant abnormal laboratory finding) that occurred in the protocol-specified AE reporting period. An AE included medical conditions, signs, and symptoms not previously observed in the participant that emerged during the protocol-specified AE reporting period, including signs or symptoms associated with pre-existing underlying conditions that were not present prior to the AE reporting period. An AE that met one or more of the following criteria or outcomes was classified as serious: death; life-threatening; in-patient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect; was considered a medically important event not meeting the above criteria, but which could jeopardize a participant, or could require medical or surgical intervention to prevent one of the criteria listed in this definition. |
