Study of DISC-0974 to Assess the Safety, Tolerability, PK and PD of DISC-0974 in Participants With CKD and Anemia

This Phase 1b study of DISC-0974 will assess the safety, tolerability, pharmacokinetics (PK) and Pharmacodynamics (PD) of DISC-0974 in adult participants with Non-Dialysis Dependent Chronic Kidney Disease and Anemia.
