Current Status: Why Oxbryta is Being Denied
Oxbryta (voxelotor) faced a significant setback in November 2024 when Pfizer voluntarily withdrew its FDA approval for sickle cell disease treatment. This withdrawal followed post-approval studies that failed to confirm clinical benefit, making virtually all new coverage requests subject to automatic denial.
However, this doesn't mean all hope is lost. Patients who were stable on Oxbryta before the withdrawal may have grounds for appeal based on:
- Documented clinical stability and response
- Lack of suitable alternatives in their specific case
- Risk of disease progression if therapy is discontinued
From our advocates: We've seen cases where patients successfully maintained coverage for withdrawn medications by emphasizing individual clinical response and the risks of sudden discontinuation. The key is building a compelling case around your unique medical circumstances rather than general efficacy data.
