This convergence of pharma and digital health could significantly enhance the drug's value proposition if integrated into comprehensive epilepsy management platforms.

MARKET CHALLENGES

Biosimilar Competition to Pressure Market Share

With key patents expiring in major markets, Perampanel faces increasing competition from generic alternatives. Recent market data shows that generic antiepileptic drugs typically capture 40-60% market share within 3 years of patent expiration. This shift is already visible in Europe where multiple biosimilar versions have launched with 30-50% price discounts. Originator companies must demonstrate superior real-world outcomes or develop next-generation formulations to maintain brand preference in this increasingly cost-sensitive therapeutic area.

Complex Reimbursement Landscapes to Impact Accessibility

The drug's premium pricing creates reimbursement challenges, particularly in value-based healthcare systems. Many payers require prior authorization for Perampanel or place it on higher cost-sharing tiers due to the availability of older, less expensive alternatives. These reimbursement barriers are particularly pronounced in managed Medicaid programs and emerging markets with strict cost-effectiveness requirements. Such hurdles may continue to limit patient access despite the drug's clinical advantages in refractory epilepsy cases.
