DRG epidemiologists estimate that 40% of epilepsy patients experience generalized-onset seizures (GOS). The most commonly prescribed early-line treatments for GOS are older antiepileptic drugs (AEDs), such as valproic acid, levetiracetam, topiramate, and lamotrigine.To date, perampanel is the only third-generation AED approved for generalized epilepsy. Neurologists consider many factors when choosing among the numerous first-, second-, and third-generation AEDs and must make adjustments throughout a patient’s disease course to achieve optimal seizure control. Understanding the evolving journey of epilepsy patients with GOS provides important context about the complex, saturated, and heavily generic drug market that developers of new AEDs will enter, should they pursue an expanded labeling for GOS. For the first time, our 2019 Treatment Algorithms series offers this GOS segmentation, as well as a companion study on partial-onset seizures (POS).

QUESTIONS ANSWERED

  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed epilepsy patients with GOS? What are the quarterly trends in prescribing among recently treated and newly diagnosed epilepsy GOS patients?
  • How have Fycompa, Trokendi XR, and Qudexy XR been integrated into the treatment algorithm, and what is their source of business?
  • What percentage of newly diagnosed epilepsy patients with GOS receive drug therapy within our tracking period, and how quickly do they receive it? What percentage of patients progress to later lines of therapy during our tracking period?
  • What percentage of epilepsy patients with GOS are treated with monotherapy versus combination therapy? What are the most commonly used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients with GOS?
