---|---|
Experimental: rHuEPO or DA to ASP1517
Participants will receive roxadustat according to the prior randomization treatment, with starting doses of 70mg thrice weekly (TIW) to participants on <4500 IU/week of rHuEPO or <20 microgram (μg)/week of darbepoetin alfa (DA) and 100mg TIW to participants on ≥4500 IU/week rHuEPO or ≥ 20 μg/week DA. Participants roxadustat dosage will be adjusted every 4 weeks to maintain Hb level within the target range 10.0 to 12.0 g/dL. Dose adjustment steps will be as follows: 20, 40, 50, 70, 100, 150, 200, 250, 300 mg.
