Randomized Controlled TrialDeramciclane in the treatment of generalized anxiety disorder: a placebo-controlled, double-blind, dose-finding study.
Deramciclane, a camphor derivative, is a novel anxiolytic agent with a unique mechanism of action. It acts as a potent and specific antagonist at serotonin 5-HT2A/2C receptors, and exhibits anxiolytic efficacy in animal models. The aim of this double-blind, placebo-controlled, parallel-group study was to evaluate the efficacy, safety, and tolerability of a range of doses of deramciclane in patients with generalized anxiety disorder (GAD). ⋯ In conclusion, deramciclane 60 mg/day showed significant evidence of efficacy for the treatment of GAD in adult patients. The efficacy for the 30 mg/day dose was close to the larger dose although not significant in the primary analysis, and there was no significant evidence of efficacy for the 10 mg/day dose. Deramciclane was safe and well-tolerated up to the 60 mg/day dose over an 8-week period.
