ListOutcomeTime frameDescription
PrimaryNumber (%) of Participants With an Hb Response by Week 17Up to Week 17An Hb response was defined as a Hb level of ≥11 g/dL and an increase from BL ≥1 g/dL.
SecondaryNumber (%) of Participants With an Hb Response by Weeks 5, 9, 13, 17, 21, and 25Up to Weeks 5, 9, 13, and 17 (all cohorts) and Weeks 21 and 25 (24-week treatment cohorts only)An Hb response was defined as a Hb level of ≥11 g/dL and an increase from BL ≥1 g/dL.
SecondaryChange From Baseline in Hb at Weeks 5, 9, 13, 17, 21, and 25Baseline, Weeks 5, 9, 13, and 17 (all cohorts) and Weeks 21 and 25 (24-week treatment cohorts only)Baseline is defined as the mean of the last 3 available values predose.
SecondaryNumber (%) of Participants With Mean Hb Between 11-12, 11-13, and 10.5-13 g/dL During Weeks 5-8, 9-12, 9-16, 13-16, 17-20, 17-24, 21-24, and 25-28Weeks 5-8, 9-12, 9-16, 13-16, and 17-20 (all cohorts) and Weeks 17-24, 21-24, and 25-28 (24-week treatment cohorts only)Participants can have a Hb value reported for more than 1 of the categories (11-12, 11-13, and 10.5-13 g/dL) during the week intervals since these categories are not mutually exclusive.
SecondaryNumber (%) of Participants With 2 Consecutive Hb Values Between 11-12, 11-13, and 10.5-13 g/dL During Weeks 5-8, 9-12, 13-16, 9-16, 17-20, 17-24, 21-24, and 25-28Weeks 5-8, 9-12, 9-16, 13-16, and 17-20 (all cohorts) and Weeks 17-24, 21-24, and 25-28 (24-week treatment cohorts only)
SecondaryNumber (%) of Participants Who Achieve Maximum Hb Between 11-12, 11-13, and 10.5-13 g/dL by Weeks 5, 9, 13, 17, 21, and 25Weeks 5, 9, 13, and 17 (all cohorts) and Weeks 21 and 25 (24-week treatment cohorts only)Participants can have a Hb value for the same category (11-12, 11-13, or 10.5-13 g/dL) reported for multiple weeks.
SecondaryNumber (%) of Participants With Maximum Hb <11, >12, >13, and >14 g/dL During Weeks 5-8, 9-12, 9-16, 13-16, 17-20, 17-24, 21-24, and 25-28Weeks 5-8, 9-12, 9-16, 13-16, and 17-20 (all cohorts) and Weeks 17-24, 21-24, and 25-28 (24-week treatment cohorts only)
SecondaryMedian Time to Hb Response: Hb Increase ≥1 g/dL From Baseline and Hb ≥11 g/dLUp to Week 17 (Cohorts A and B) and up to Week 25 (Cohorts C-F)
Median time to response was estimated using Kaplan Meier method, Cohort A and B censored at Week 17, Cohort C, D, E, and F censored at Week 25. The median number of days presented was calculated from Baseline to the day the Hb response was achieved.
SecondaryMedian Initial Hb Responsive Time: Time to Initial Hb Increase ≥1.0 g/dL From BaselineUp to Week 17 (Cohorts A and B) and up to Week 25 (Cohorts C, D, E, and F)
Median time to response was estimated using Kaplan Meier method; Cohort A and B censored at Week 17 and Cohort C, D, E, and F censored at Week 25. The median number of days presented was calculated from Baseline to the day the Hb response was achieved.
