- InterventionsThe investigational product (IP) consists of bumetanide 0.5 mg tablets or placebo, which will be provided as an add-on treatment, supplementary to the regular use of AEDs or other (allowed) comedications. Dose reductions to manage side effects will be allowed at any time. Due to the expected chance of frequent mild to moderate hypokalemia, all subjects will receive standard potassium supplementation during the 91 days of treatment. The treatment period will be followed by a wash-out period to evaluate return of symptomatology and reversibility of treatment effect.

Placebo product will be administered as comparator of the Bumetanide in exact similar tablets. The qualitative and quantitative composition in excipients of the Placebo product is comparable to that of Bumetanide 0.5 mg tablets.
