Input:Carisbamate in essential tremor: brief report of a proof of concept study.  The efficacy and safety of carisbamate, an investigational neuromodulator currently in development for epilepsy, were examined in a multicenter, randomized, double-blind, cross-over, placebo-controlled study of essential tremor. Sixty-two patients (intent-to-treat analysis set; mean age 64 years; 66% men) received carisbamate 400 mg/day or matching placebo in a crossover study design with two 21-day treatment periods. The Fahn-Tolosa-Marín Tremor Rating Scale (TRS) was the primary assessment tool. Carisbamate and placebo treatment did not differ in their effect on the TRS (P = 0.94) or on measures of affect, mood, or quality of life. Carisbamate was generally well tolerated and had an adverse event profile comparable to that of placebo. Output:
{'conditions': 'Essential Tremor, Movement Disorders', 'interventions': 'Drug: Carisbamate|Drug: Placebo'}
