Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Roxadustat | Participants received roxadustat tablets orally TIW. The initial dose was according to the tiered weight-based approach, with starting roxadustat doses of 70 mg TIW to participants weighing \<70 kg and roxadustat doses of 100 mg TIW to participants weighing ≥70 kg. Dose-titration (up to a maximum dose of 300 mg) was performed based upon regular measurement of Hb levels until the participant achieved central Hb value of ≥11.0 g/dL and Hb increase from BL of ≥1.0 g/dL at 2 consecutive study visits, separated by at least 5 days. Once target Hb level was reached, the participant entered the maintenance period during which roxadustat dosage will be adjusted every 4 weeks to maintain participant's Hb level within the target range of 10.0 g/dL and 12.0 g/dL. The maximum treatment duration was 234.9 weeks. | 321 | 611 | EG000 |
| Group 2 | Placebo | Participants received roxadustat-matching placebo tablets orally TIW. The initial dose was according to the tiered weight-based approach, with starting roxadustat-matching placebo doses of 70 mg TIW to participants weighing \<70 kg and roxadustat-matching placebo doses of 100 mg TIW to participants weighing ≥70 kg. Dose-titration (up to a maximum dose of 300 mg) was performed based upon regular measurement of Hb levels until the participant achieved central Hb value of ≥11.0 g/dL and Hb increase from BL of ≥1.0 g/dL at 2 consecutive study visits, separated by at least 5 days. Once target Hb level was reached, the participant entered the maintenance period during which roxadustat dosage was adjusted every 4 weeks to maintain participant's Hb level within the target range of 10.0 g/dL and 12.0 g/dL. The maximum treatment duration was 208.1 weeks. | 120 | 305 | EG001 |
