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 market is heavily genericized, and most of the anti epileptic drugs (AEDs) can be used as monotherapies or in combination. However, recent entrants like cenobamate, fenfluramine, and ganaxolone are carving share in the market, despite being high-priced branded products, by targeting underserved and orphan epilepsy populations. This report provides a detailed account of dynamics in this complex market, including the continued dominance of second-generation AEDs while emerging therapies nevertheless gain traction by addressing unmet needs in this diverse patient population.

Questions answered

  • What is the current size of epilepsy market by country, and how do we forecast the market will evolve in the coming years?
  • What key factors will shape the future market, and what drivers and barriers will influence the use of key AEDs? Will the dominance of second-generation therapies continue, and which third-generation therapies will be successful over our forecast period?
  • How will high-priced third-generation AEDs fare in this highly genericized market?
  • How have UCB’s Nayzilam and Neurelis’s Valtoco been integrated into the treatment algorithm?
  • What are the unmet needs in the current epilepsy treatment paradigm? How will emerging therapies address these unmet needs?
