Brief Summary

JTZ-951 is a currently being developed as a treatment for renal anemia. This study aims to evaluate the efficacy and safety of JTZ-951 following a switch from erythropoiesis-stimulating agent (ESA) in Korean subjects receiving HemoDialysis with renal anemia.

This study is a Phase III, open, active-controlled, parallel-group, multi-center study.

The total duration of the study will be 30 weeks including screening, treatment and follow-up.
