Epilepsy – Landscape & Forecast – Disease Landscape & Forecast

Epilepsy, which afflicts approximately 4.7 million people in the major markets according to Clarivate epidemiology, is a heterogeneous condition requiring individualized treatment based largely on a patient’s seizure syndrome and seizure type. The epilepsy market has more than 25 antiepileptic drugs (AEDs), most of them generic, that can be effective for many patients as monotherapies or in combination. In this challenging market environment, developers have increasingly targeted underserved, orphan pediatric epilepsy populations, for which several products have been approved in recent years, with more in development. Understanding the trajectory of the established epilepsy market and the evolving competitive landscape in niche segments is critical for marketers of both current and emerging brands to retain market share or carve out a clinical role.

Questions answered

  • What is the state of treatment in epilepsy across the G7, and what needs are left unfulfilled by approved AEDs?
  • What are the market opportunities and sales potential for agents targeting treatment-refractory focal epilepsy patients (e.g., Xcopri) and for agents targeting orphan epilepsy subpopulations (e.g., Epidiolex, Fintepla)?
  • What clinical role will the newer entrants (e.g., Eprontia, Valtoco) and emerging therapies (e.g., Libervant) play in the epilepsy market?
  • How will neurologists differentiate among current and emerging third-generation AEDs, and which of these agents will enjoy the greatest clinical and commercial success in the face of strong generics competition?
