Groups2

Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

GroupTitleDescriptionWith the outcomeAnalysedClinicalTrials.gov code
Group 1Roxadustat
Participants received roxadustat orally according to the tiered weight-based approach, with starting dose of 70 mg given TIW to participants weighing between 45 kg up to 70 kg and 100 mg given TIW to participants weighing more than 70 kg up to 160 kg. Dose-titration was performed based upon regular measurement of Hb levels until participants achieved central Hb value of ≥ 11.0 g/dL and Hb increase from baseline of ≥ 1.0 g/dL at two consecutive study visits, separated by at least 5 days. Once target Hb level was reached participants entered maintenance period during which roxadustat dosage was adjusted every 4 weeks to maintain participants Hb level within the target range of 10.0 g/dL and 12.0 g/dL. Participants received roxadustat for up to a maximum of 104 weeks.

Group 2Darbepoetin Alfa
Participants received initial dose of darbepoetin alfa based upon the weight \[either 0.45 μg/kg of body weight, as a single subcutaneous or IV injection once weekly or 0.75 μg/kg of body weight, as a single subcutaneous injection once every 2 weeks\] as per EU SmPC along with IV iron supplementation according to the standard of care. Dose-adjustment was performed based upon regular measurement of Hb levels until participants achieved central Hb value of ≥ 11.0 g/dL and Hb increase from baseline of ≥ 1.0 g/dL at two consecutive study visits, separated by at least 5 days. Once target Hb level was reached participants entered maintenance period during which darbepoetin alfa dosage was adjusted every 4 weeks to maintain participants Hb level within the target range of 10.0 g/dL and 12.0 g/dL. Participants received darbepoetin alfa for up to a maximum of 104 weeks.
