Material Changes and Clinical Results
The HIBISCUS trial successfully met both co-primary endpoints, demonstrating superior efficacy compared to placebo in 385 participants aged 12 years or older:
- Vaso-occlusive Crisis (VOC) Reduction: Etavopivat demonstrated a 27% reduction in the annualized rate of VOCs.
- Time to First VOC: Median time to first VOC was prolonged to 38.4 weeks with etavopivat versus 20.9 weeks with placebo.
- Haemoglobin Response: 48.7% of treated patients achieved a haemoglobin increase of >1g/dL at week 24, compared to 7.2% on placebo (adjusted rate difference of 41.2%).
- Transfusion Risk: Exploratory analysis indicated a significant reduction in the risk of blood transfusion.
- Safety: The drug appeared well-tolerated with a safety profile consistent with previous trials.
Guidance, Outlook, and Management Commentary
Management views etavopivat as a potential "first and best-in-class" therapy that could transform care for the approximately 8 million people worldwide living with SCD. Martin Holst Lange, Executive Vice President and Chief Scientific Officer, emphasized the company's commitment to health equity and access.
Regulatory Outlook: Novo Nordisk plans to submit for the first regulatory approval of etavopivat in the second half of 2026. Detailed results are scheduled for presentation at a scientific conference in 2026.
Risks and Contingencies: While the trial was successful, the filing notes that SCD is a life-shortening disease with limited current therapeutic options. The company holds Fast Track, Rare Pediatric Disease, and Orphan Drug designations from the FDA and European Commission, which may influence the regulatory pathway but do not guarantee approval.
