KEVEYIS was shown to reduce the number, duration, and severity of attacks of Primary Periodic Paralysis.1
Results in Study 1: Hypokalemic patients treated with KEVEYIS had 2.2 fewer attacks per week than patients treated with placebo. Hyperkalemic patients treated with KEVEYIS had 3.9 fewer attacks per week than patients treated with placebo.2
Results in Study 2: Hyperkalemic patients treated with KEVEYIS had 2.3 fewer attacks per week than patients treated with placebo. For hypokalemic patients, the primary endpoint was the occurrence of an intolerable increase in attack frequency or severity, necessitating withdrawal from the treatment phase. Out of 15 patients, the majority reached acute worsening in the placebo phase.3
In study 1, the most common side effects of KEVEYIS were tingling or prickling sensations ("pins and needles"), feeling confused and having trouble paying attention, and changes in taste.1
KEVEYIS is a 50 mg tablet that is taken once or twice daily when starting therapy. Dosing can be increased or decreased at weekly intervals (or sooner in case of adverse reactions) based on individual response. The maximum recommended daily dose is 200 mg.1
