Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of the study is to assess pharmacodynamic (PD) activity of E2082 as measured by suppression of epileptic photoparoxysmal response (PPR) in the participant's most sensitive eye condition in participants with photosensitive epilepsy, compared to placebo.
