Eton Pharma NDA for Liquid Epilepsy Drug

Eton Pharmaceuticals has submitted an NDA for zonisamide (previously known as ET-104) oral suspension for treating partial seizures in patients with epilepsy. Zonisamide is widely used as a capsule to treat partial seizures, but the molecule is not FDA-approved in a liquid form. Eton says its patent-pending liquid formulation addresses the significant unmet need for patients with dysphagia and patients that require the precision dosing that a liquid product offers. Based on recent data, more than 150,000 prescriptions of zonisamide are written annually for the indication. ET-104 is one of the company’s three neurology-focused liquid product candidates, along with ET-105 (lamotrigine oral suspension) and ET-101 (topiramate oral solution). Eton expects all three to be approved and launched in 2021.
