Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Roxadustat

Participants will receive roxadustat as an oral tablet, 3 times per week (TIW) for up to a maximum of 24 weeks. If a participant requires roxadustat \<60 milligrams (mg)/week to maintain Hb levels, the dose frequency will be reduced in a stepwise manner, for example, to BIW, and then QW. For participants converted from CERA, the initial roxadustat dose will be based on the average prescribed CERA dose in the last 8 weeks prior to conversion. For participants with \<6 weeks of prior CERA use, the initial roxadustat dose will be based on a 2-tiered, weight-based dosing scheme. Dose adjustment evaluations will be made every 4 weeks and doses will be titrated based on Hb level and rate of Hb change. The prescribed dose will not exceed the maximum allowable dose of 3.0 mg/kilogram (kg)/dose or 400 mg per dose, whichever is lower.
