Participant Flow

A total of 534 participants were screened for entry into the study. Of 534 participants, 147 were screen failures and 387 were eligible to continue in the study. A total of 390 participants were randomized into the study; 387 who were eligible and 3 who failed screening but were inappropriately randomized (2 received study treatment and 1 did not).

This was a randomized, double-blind, placebo-controlled study consisting of three phases: Prerandomization, Double-blind, and Follow-up. Participants who experienced the required minimum number of seizures during prerandomization, entered the Double-blind Phase and were randomized to placebo or 8 or 12 mg perampanel groups.
