Zydus Gets USFDA Orphan Drug Status for Desidustat to Treat Sickle Cell Disease

Zydus Lifesciences has received Orphan Drug Designation (ODD) from the US Food and Drug Administration for Desidustat, an oral drug being developed to treat sickle cell disease (SCD).
The orphan status is given to medicines aimed at treating rare diseases affecting fewer than 200,000 people in the United States and helps support their development.
About Desidustat
Desidustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI).
It has the potential to increase haemoglobin levels and red blood cell counts, which may help patients suffering from sickle cell disease.
Limited Treatment Options for Sickle Cell Disease
Current treatments for SCD remain limited.
- Hydroxyurea can reduce painful crises but is not effective for all patients and may cause side effects.
- Blood transfusions are costly, not always available, and carry medical risks.
A Phase II clinical study of Desidustat has already been completed, and the results are expected to be published in a medical journal.
Benefits of Orphan Drug Status
The USFDA designation provides several development incentives, including:
- Tax credits for clinical testing
- Waiver of certain regulatory fees
- Potential seven-year marketing exclusivity in the US after approval
Management Commentary
Zydus Managing Director Dr. Sharvil Patel said the designation highlights the urgent need for new treatments for sickle cell disease and expressed confidence that Desidustat could help address this unmet medical need.
