About this study

Multicenter, placebo-controlled, double-blind, randomized, parallel-group, Phase 2b study in pediatric subjects (aged greater than equal to 6 to less than 18 years of age) with TS. Following a 28-day Screening period and Baseline visit, eligible subjects will be randomized 1:1 to receive either ecopipam hydrochloride (HCl) or matching placebo for a 12 week treatment period. Doses will be titrated up and down from target dose of 2 mg/kg/day. Follow Up visit will be conducted after the last dose of study medication.

Primary outcomes

  1. Change From Baseline in the Yale Global Tic Severity Scale-Total Tic Score (YGTSS-TTS) at Week 12

    Time frame: Baseline, Week 12

    The YGTSS was a semi-structured clinical interview designed to measure the tic severity. This scale consisted of a tic inventory, with 5 separate rating scales to rate the severity of symptoms, and an impairment ranking. Ratings were made along 5 different dimensions on a scale of 0=none to 5=severe for motor and vocal tics, each including number, frequency, intensity, complexity, and interference. The YGTSS TTS was the summation of the severity scores of motor and vocal tics. The total tic score (TTS) ranged from 0 (none) to 50 (severe) with higher score represent more severe symptoms. A negative change from baseline indicates improvement.

Secondary outcomes

  1. Change From Baseline in Clinical Global Impression of Tourette Syndrome Severity (CGI-TS-S) at Week 12

    Time frame: Baseline, Week 12

    Clinical Global Impression (CGI) scale was used to assess overall severity on a 7-point Likert scale consisted of 2 reliable and valid 7-item Likert scales used to assess severity and change in clinical symptoms. The CGI severity scale ranges from 1 = Normal, not at all ill; 2 = Borderline ill; 3 = Mildly ill; 4 = Moderately ill; 5 = Markedly ill; 6 = Severely ill; 7 = Among the most extremely ill subject. 1 = "normal, not ill at all" to 7 = "extremely ill." A negative change indicates improvement in the condition.
