Safety and Tolerability of Intravenous Brivaracetam (Infusion or Bolus) as Adjunctive Antiepileptic Therapy

A Multi-center, Open-label, Four-arm, Randomized Trial Evaluating the Safety and Tolerability of Brivaracetam Intravenous Infusion and Bolus, Administered in BID Regimen as an Adjunctive Antiepileptic Treatment in Subjects From 16 to 70 Years Suffering From Epilepsy

This is a multicenter, open-label, 4-arm, randomized, parallel-group study to evaluate safety and tolerability of Brivaracetam Intravenous (BRV iv) as adjunctive treatment for adults with epilepsy according to an initiation or a conversion scheme, during repeated dosing (100 mg/administration twice daily for 4.5 days).

Eligible subjects will be randomized in a 1:1:1:1 ratio to the 4 treatment arms
