Brief summary
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).
Detailed description
Eligible subjects will be randomized in a 1:1:1:1 ratio to the 4 treatment arms
Interventions
100 mg, intake twice daily (BID) for 7 days during Run-In Period
10 mL (= 100 mg) of Brivaracetam administered intravenously over 2 minutes twice daily (BID) during Evaluation Period
10 mL (= 100 mg) of Brivaracetam diluted in 90 mL 0.9 % isotonic saline sterile solution for intravenous administration infused over 15 minutes twice daily (BID) during Evaluation Period
