Introduction to Daprodustat
Daprodustat, developed by GlaxoSmithKline (GSK), is an oral medication belonging to the class of hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs). It is designed to treat anemia associated with chronic kidney disease (CKD) by mimicking the body's response to high-altitude conditions, thereby increasing red blood cell production[1][4].
Regulatory Landscape
The regulatory journey of daprodustat has been marked by significant milestones and challenges. In October 2022, the FDA's Cardiovascular and Renal Drugs Advisory Committee (CRDAC) voted 13-3 in favor of the drug's benefits outweighing its risks for adult dialysis patients with anemia of CKD. However, for non-dialysis patients, the committee voted 5-11 against the drug, citing safety concerns[1][4].
Despite this mixed outcome, the FDA's decision is crucial, as the agency often follows the advice of its expert panels. Daprodustat has already been approved in Japan under the name Duvroq and is under review in Europe[1][4].
Market Potential
The chronic kidney disease (CKD) market is substantial and growing. As of 2024, the CKD market was valued at USD 41 billion and is projected to reach USD 82.5 billion by 2037, growing at a CAGR of 6% during the forecast period. The drug segment, which includes treatments like daprodustat, is expected to account for more than 45% of the market share by 2037[3].
In North America, particularly the U.S., the CKD market is driven by high prevalence rates of diabetes and hypertension, which are key risk factors for CKD. The comprehensive insurance coverage for CKD treatments in the U.S. also supports market growth[3].
Financial Projections
The financial trajectory of daprodustat is closely tied to its regulatory approvals and market adoption. Given the FDA advisory committee's partial endorsement, daprodustat is likely to secure approval for use in dialysis patients, which could lead to significant revenue.
Analysts estimate that daprodustat could achieve peak sales of around $1 billion, primarily driven by its use in dialysis patients. This projection is based on the drug's performance in clinical trials, which showed it to be non-inferior to existing injectable treatments for anemia in terms of major adverse cardiovascular events (MACE)[1].
Competitive Landscape
Daprodustat enters a market where other anemia treatments have faced regulatory hurdles. In the past year, the FDA has rejected two other anemia pills due to heart-related side effects, making daprodustat's partial approval a notable achievement. The drug's oral formulation offers a convenient alternative to injectable treatments, which could enhance its market appeal[1].
Clinical Trial Outcomes
The ASCEND phase III clinical trial program for daprodustat demonstrated that the drug improved and/or maintained hemoglobin levels within the target range for patients. The primary safety analysis showed that daprodustat achieved non-inferiority compared to erythropoiesis-stimulating agents (ESAs) in terms of MACE. These results support the drug's potential as a safe and effective treatment option[4].
GSK's Strategic Positioning
GSK's overall strategy and financial performance are pivotal to the success of daprodustat. In 2022, GSK reported double-digit sales growth of 13%, driven by strong performance in Specialty Medicines and Vaccines. The company's pipeline includes 69 vaccines and medicines, many of which have the potential to be first or best-in-class. This robust pipeline and the company's focus on innovation and cost discipline underpin its confidence in future growth[2].

FAQs
Q: What is daprodustat, and how does it work?
A: Daprodustat is an oral medication that belongs to the class of HIF-PHIs. It works by inhibiting oxygen-sensing prolyl hydroxylase enzymes, which stabilizes hypoxia-inducible factors, leading to the transcription of erythropoietin and other genes involved in correcting anemia.
Q: What was the outcome of the FDA advisory committee vote on daprodustat?
A: The FDA advisory committee voted 13-3 in favor of daprodustat for use in adult dialysis patients with anemia of CKD but voted 5-11 against its use in non-dialysis patients due to safety concerns.
Q: What is the projected market size for the CKD market by 2037?
A: The CKD market is projected to reach USD 82.5 billion by 2037, growing at a CAGR of 6% during the forecast period.
Q: How does daprodustat compare to other anemia treatments?
A: Daprodustat offers a convenient oral formulation, which is an advantage over existing injectable treatments. It has also shown non-inferiority to ESAs in terms of MACE.
Q: What are the estimated peak sales for daprodustat?
A: Analysts estimate that daprodustat could achieve peak sales of around $1 billion, primarily driven by its use in dialysis patients.
