Epilepsy – Current Treatment – Detailed, Expanded Analysis: Treatment Algorithms: Claims Data Analysis – Partial Onset (US)

DRG epidemiologists estimate that 60% of epilepsy patients experience partial-onset seizures (POS), which aretypically the gateway indication for new antiepileptic drugs (AEDs). The most frequently prescribed early-line treatments for POS are generic mainstays, such as levetiracetam, lamotrigine, and carbamazepine/oxcarbazepine; newer brands such as Vimpat and Briviact are prescribed in later lines of therapy, mostly to treatment-refractory patients. Neurologists consider many factors when selecting among the many first-, second-, and third-generation AEDs and make adjustments throughout a patient’s disease course to achieve optimal seizure control. Understanding the evolving journey of epilepsy patients with POS provides important context about the complex, saturated, and heavily generic market that developers of new AEDs will enter. For the first time, our 2019 Treatment Algorithms series offers this POS segmentation, as well as a companion study on generalized-onset seizures (GOS).
