Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryMean Change in Hemoglobin (Hb) Levels From Pre-treatment to the End of the Primary Efficacy PeriodPre-treatment; Week 6
The pre-treatment value for Hb was defined as the average of 2 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.
SecondaryTime to Reach the Target Hb Level of 10.0 to 12.0 g/dL From Baseline up to Week 16from 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.
SecondaryMean Hb Levels at the End of the Primary Efficacy Periodup to Week 6Data are reported as mean of the actual Week 6 values.
SecondaryMean Hb Levels at the End of the Dose Adjustment and Maintenance Periodup to Week 16Data are reported as mean of the actual Week 16 values.
SecondaryNumber of Participants Who Achieved the Target Hb Level of 10.0 to 12.0 g/dL at the End of the Dose Adjustment and Maintenance Periodup to Week 16
SecondaryMean Change in Hb Between Pre-treatment and the End of the Dose Adjustment and Maintenance PeriodPre-treatment; Week 16
The pre-treatment value for Hb was defined as the average of 2 values obtained prior to treatment, i.e., the qualifying screening value and the Baseline value. Change from Pre-treatment was calculated as the Week 16 value minus the Pre-treatment value.
SecondaryMean Change in Red Blood Cell (RBC) Count and Absolute Reticulocyte Count From Baseline to the End of the Primary Efficacy PeriodBaseline; Week 6Change from Baseline was calculated as the post-Baseline value minus the Baseline value.
SecondaryMean Change in RBC Count and Absolute Reticulocyte Count From Baseline to the End of the Dose Adjustment and Maintenance PeriodBaseline; Week 16Change from Baseline was calculated as the post-Baseline value minus the Baseline value.
SecondaryMean Change in Hematocrit and Reticulocytes From Baseline to the End of the Primary Efficacy PeriodBaseline; Week 6Change from Baseline was calculated as the post-Baseline value minus the Baseline value.
SecondaryMean Change in Hematocrit and Reticulocytes From Baseline to the End of the Dose Adjustment and Maintenance PeriodBaseline; Week 16Change from Baseline was calculated as the post-Baseline value minus the Baseline value.
