Group Intervention Description ASP1517 ESAs Treated Group roxadustat This group includes subjects who have received ESAs. The treatment was converted from ESAs to study drug. Study drug will be dosed three times weekly and dose adjustments will be made during the study. ASP1517 Low Dose Group (ESA Untreated) roxadustat This group includes subjects who have not received Erythropoieses Stimulating Agents (ESAs). Study drug will be dosed three times weekly and dose adjustments will be made during the study. ASP1517 High Dose Group (ESA Untreated) roxadustat This group includes subjects who have not received ESAs. Study drug will be dosed three times weekly and dose adjustments will be made during the study.
