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?
