What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change From Baseline to Week 8 in Yale Global Tic Severity Scale (YGTSS) Total Tic Score	The YGTSS is 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 to 5 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 (greater reduction from baseline for greater improvement).	Baseline and Week 8

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change From Baseline in Clinical Global Impressions Scale for Tourette's Syndrome (CGI-TS) Score	The severity of illness and efficacy of study medication for each participant were rated using the CGI-TS scale. The study physician rated the participants total improvement whether or not it is due to study treatment. All responses were compared to the participants condition at Baseline (Day 0). Response choices include: 0 = not assessed, 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse. A negative change from Baseline indicates improvement.	Baseline and Week 8
Mean Change From Baseline in Gilles de la Tourette Quality of Life (GTS-QOL) Overall Score at Week 8	The GTS-QOL is a disease-specific patient-reported scale for the measurement of health-related quality of life in participants with Tourette's Disorder, taking into account the complexity of the clinical picture of the disease. The questionnaire consists of a 27-item Tourette's Disorder-specific scale with 4 subscales (psychological, physical, obsessional, and cognitive). The GTS-QOL total score ranged from 0 (extremely dissatisfied with life) and 100 (extremely satisfied with life). A positive change from Baseline indicates improvement.	Baseline and Week 8
