Daprodustat: A Hypoxia-Inducible Factor-Prolyl Hydroxylase Inhibitor for Anemia of Chronic Kidney Disease.

OBJECTIVE

The objective was to review the safety and efficacy of daprodustat, a hypoxia-inducible factor-prolyl hydroxylase inhibitor (HIF-PHI) in the treatment of anemia of chronic kidney disease (CKD).

DATA SOURCES

A literature search was conducted in MEDLINE, EMBASE, and ClinicalTrials.gov using the keywords "daprodustat," "GSK1278863," and "hypoxia-inducible factor-prolyl hydroxylase inhibitors" from January 2010 through November 2023.

STUDY SELECTION AND DATA EXTRACTION

Literature was included if it evaluated pharmacology, pharmacokinetics, efficacy, and/or safety of daprodustat in human subjects and was reported in English. The manufacturer's product monograph was also utilized.

DATA SYNTHESIS

Daprodustat significantly increased hemoglobin levels in CKD patients on dialysis (difference 0.18 g/dL) and not on dialysis (difference 0.08 g/dL) over 52-week treatment periods compared with erythropoiesis stimulating agents (ESA) in Anemia Studies in CKD: Erythropoiesis via a Novel PHI Daprodustat (ASCEND)-D and ASCEND-ND, respectively. First occurrence of major adverse cardiovascular events (MACEs) was similar between daprodustat and ESAs in both trials.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS

Daprodustat can be used in patients with CKD on dialysis and already receiving an ESA for at least 6 weeks to further increase serum hemoglobin levels without increasing the risk of MACE. Adverse effects of daprodustat that may occur more than ESAs include headache, emesis, and thrombosis.

CONCLUSIONS

Daprodustat is a novel oral, non-iron therapy for treatment of anemia of CKD. It was Food and Drug Administration approved in 2023 in patients already receiving dialysis for at least 4 months but not in non-dialysis patients. Long-term data for safety and additional benefits are pending.
