Official Title: A Double-blind, Randomised, Placebo-controlled, Multi-centre Study to Assess the Efficacy and Safety of Adjunctive Zonisamide in Myoclonic Seizures Associated With Idiopathic Gen
Brief Summary: This study is intended to provide evidence that zonisamide is safe and effective in the treatment of myoclonic seizures. The total planned trial duration will be 6.5 months. After that, subjects who have completed the study will be eligible to enroll in an open-label extension study until zonisamide is marketed for this indication or further development in this indication stops.
