Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to evaluate the efficacy and safety of roxadustat compared with active control (epoetin alfa) for the maintenance treatment of anemia in participants with ESRD on dialysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will consist of three study periods as follows:

1. Screening Period of up to 6 weeks (8 weeks if on Mircera)
2. Treatment Period: a minimum of 52 weeks, a maximum of up to 3 years from the date last participant is randomized. Minimum study duration for participants enrolled under Protocol Amendment 1 or 2 may be less than 52 weeks
3. A Follow-up period of 4 weeks.

Participants will be randomized in a 1:1 ratio to receive either roxadustat or epoetin alfa (active control) in an open-label manner.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Roxadustat

Participants will receive roxadustat tablets, administered orally 3 times weekly (TIW). Initial roxadustat dose will be based on the participant's average prescribed erythropoietin stimulating agent (ESA) dose in the 4 weeks (if on epoetin or darbepoetin or 8 weeks (if on Mircera®) prior to randomization. Dose adjustments will be permitted to maintain a hemoglobin (Hb) level of approximately 11 grams (g)/deciliter (dL). The maximum roxadustat dose is 3.0 milligrams (mg)/kilogram (kg) per dose or 400 mg per administration (whichever is lower).

Group Type EXPERIMENTAL

Roxadustat

Intervention Type DRUG

Roxadustat will be administered per dose and schedule specified in the arm.

Epoetin Alfa

Participants on hemodialysis (HD) will receive epoetin alfa, administered intravenously (IV) TIW and participants on home HD or peritoneal dialysis (PD) will receive epoetin alfa, administered subcutaneously (SC). Initial epoetin alfa dose will be based on the participant's average weekly prescribed ESA dose in 4 weeks prior to randomization if on epoetin or darbepoetin, and average monthly (4-week) prescribed ESA dose in 8 weeks prior to randomization if on Mircera®. In case of a change in route of administration from SC to IV (TIW), the initial dose of IV epoetin alfa will be determined by the investigator per local standard of care (SOC). Dose adjustments will follow the recommendations as per the approved country-specific product label (United States Package Insert \[USPI\] or Summary of Product Characteristics \[SmPC\]) or local SOC.
