Open-Label Extension Study for the Long-Term Efficacy and Safety of Roxadustat in Participants With Dialysis and Non-Dialysis Chronic Kidney Disease

The purpose of this open-label extension study is to evaluate long-term efficacy and safety of roxadustat in maintaining hemoglobin (Hb) in participants with dialysis and non-dialysis chronic kidney disease (CKD) who have completed the Treatment Period of a roxadustat FibroGen-sponsored anemia study.

This is an open-label, long-term maintenance study of roxadustat anemia therapy in participants with dialysis and non-dialysis CKD who have completed the Treatment Period of a roxadustat FibroGen-sponsored anemia study. Participants assigned to roxadustat in the previous study will continue to receive the same roxadustat dose and dosing frequency, unless a dose adjustment is required.
