Conditions

Anemia of Chronic Kidney Disease

Brief summary

This trial is an investigator-initiated, multi-center, randomized (1:1), open-label, active-controlled, pragmatic study of the safety of vadadustat administered three times per week for the treatment of anemia in in-center hemodialysis patients with End Stage Kidney Disease (ESKD). This study will obtain long-term safety data in a large sample of subjects receiving in-center hemodialysis to support adoption of three times per week vadadustat dosing.

Interventions

DRUGVadadustat

A synthetic, orally bioavailable, small molecule being developed as an inhibitor of hypoxia-inducible factor prolyl-hydroxylases for the treatment of anemia associated with chronic kidney disease. Intervention to be administered to maintain hemoglobin within a target range of 10-11 g/dL.

Standard of care erythropoiesis stimulating agent will be administered to maintain hemoglobin within a target range of 10-11 g/dL.
