Interventions
Registration Number
NCT05615220
Lead Sponsor
Emalex Biosciences Inc.
Brief Summary

This Phase 3 multicenter study evaluates the maintenance of efficacy, safety and tolerability of ecopipam tablets in children, adolescents and adults in the treatment of Tourette's Disorder (TD). The study includes an open-label period followed by double-blind, placebo-controlled, randomized withdrawal period.

Detailed Description

Following a 28-day Screening period and Baseline visit, eligible subjects will be enrolled into the open-label Stabilization period comprised of a 4-week Titration phase to achieve a target steady-state dose of 1.8 mg/kg/day ecopipam (2 mg/kg/day ecopipam HCl) followed by an 8-week open-label Maintenance phase. Responders to ecopipam will be randomized to ecopipam 1.8 mg/kg/day (2 mg/kg/day ecopipam HCl) or placebo in a 1:1 fashion and enter the double-blind Randomized-Withdrawal (R/WD) period at Week 12. During the 12-week R/WD period, any subject meeting Relapse criteria will be withdrawn from blinded study medication and complete end of study assessments including safety follow up visits.
