Clinical Trial Summary

The primary objective of this study is to evaluate the efficacy and safety of roxadustat in participants with end-stage renal disease (ESRD) on maintenance hemodialysis (HD) therapy, previously treated with intravenous (IV) epoetin alfa.


Clinical Trial Description

Dose ranging study with consecutive cohorts in two participant populations: participants normally responding to current anemia treatment (epoetin alfa) ("normoresponders": participants with baseline epoetin alfa dose at study entry 75 to 450 international units [IU]/kilograms [kg]/week) and participants not responding well to current treatment ("hyporesponders": participants with maintenance epoetin alfa dose above 450 IU/kg/week). Normoresponders are randomized to study drug roxadustat or epoetin alfa at a ratio of 3:1; hyporesponders are randomized to study drug roxadustat or epoetin alfa or placebo at a ratio of 2:1:1. The study objectives are to demonstrate that roxadustat is effective in maintaining hemoglobin (Hb) levels when converting from epoetin alfa and to establish optimum starting doses and dose adjustment regimens for Hb maintenance. ;
