Regulatory and Patent Considerations
- Patent protections: Patents expire in late 2028, opening opportunities for biosimilar development.
- Regulatory landscape: Submissions for biosimilars or second-generation monoclonal antibodies could pressure prices.
Key Market Challenges
- Limited indications: Zinplava is indicated solely for preventing recurrence, restricting utilization scope.
- Cost of therapy: High upfront cost limits adoption in some healthcare settings.
- Competition from emerging therapies: Novel agents targeting CDI will influence pricing and market share.
