The purpose of the study is to evaluate the safety and efficacy of roxadustat for treatment of anemia in patients with chronic kidney disease not on dialysis.

Official Title

A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Safety and Efficacy of Roxadustat for the Treatment of Anemia in Chronic Kidney Disease Patients Not on Dialysis


This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study in anemic patients with Stage 3, 4 or 5 chronic kidney disease (CKD) who are not on dialysis.
