ListOutcomeTime frameDescription
PrimaryChange From Baseline in Electrocardiogram (ECG) Values Parameters: Aggregate PR Interval, Aggregate QRS Duration, Aggregate QT Interval, and Aggregate QTc IntervalBaseline to Month 12
Baseline was defined as the last measurement taken before the first dose of open-label treatment on Day 1 of current study. Change From Baseline in ECG parameters aggregate PR interval, aggregate QRS duration, aggregate QT interval, and aggregate QTc interval expressed in millisecond (msec) was reported.
PrimaryNumber of Participants With Clinically Significant Abnormal Physical Examination FindingsBaseline up to Month 12
Physical examination included examination of the following body areas and systems: Head, Eyes, Ears, Nose, Mouth, Throat, Neck (including Thyroid), Thorax, Abdomen, Urogenital, Extremities, Neurological, Skin and Mucosae and Others. Any clinically significant abnormalities in physical examination were judged by the investigator. Only non-zero values are reported.
SecondaryChange From Baseline in the Yale Global Tic Severity Scale -Total Tic Score (YGTSS-TTS) at Months 1, 3, 6, 9 and 12Baseline up to Months 1, 3, 6, 9 and 12
The YGTSS was a clinician-completed rating scale used to quantify overall tic severity as well as specific subdomains of tic number, frequency, intensity, complexity and interference. Each of these subdomains was scored, on a 0 to 5 scale, separately for motor and vocal tics and then summed across both motor and vocal tics to yield a total tic score ranging from 0 to 50. Higher scores represent more severe symptoms. A negative change from baseline indicates improvement.
SecondaryChange From Baseline in the Yale Global Tic Severity Scale - Impairment (YGTSS-I) at Months 1, 3, 6, 9 and 12Baseline up to Months 1, 3, 6, 9 and 12
The YGTSS was a clinician-completed rating scale used to quantify overall tic severity as well as specific subdomains of tic number, frequency, duration, intensity, and complexity. Each of these subdomains was scored, on 0 to 5 scale, separately for an overall impairment rating from (0 = ''none'' to 50 = ''severe''). Higher score represent more severe symptoms. A negative change from baseline indicates improvement.
SecondaryChange From Baseline in the Yale Global Tic Severity Scale - Global Score (YGTSS-GS) at Months 1, 3, 6, 9 and 12Baseline up to Months 1, 3, 6, 9 and 12
The YGTSS was a clinician-completed rating scale used to quantify overall tic severity as well as specific subdomains of tic number, frequency, duration, intensity, and complexity. Each of these subdomains was scored, on a 0 to 5 scale, separately for motor and vocal tics and then summed across both motor and vocal tics to yield a tic severity score ranging from 0 to 50. The YGTSS also provides for an overall impairment rating (0 = ''none'' to 50 = ''severe''). YGTSS-GS is the total of YGTSS-TTS and YGTSS-I. The maximum YGTSS Global score is 100, while the maximum motor score is 25, the maximum vocal score is 25, and the maximum impairment score is 50. Higher scores indicate more severe tics. A negative change from baseline indicates improvement.
SecondaryChange From Baseline in Clinical Global Impression of Tourette Syndrome of Severity (CGI-TS-S) at Months 1, 3, 6, 9, 12Baseline up to Months 1, 3, 6, 9, 12
The CGI consists of 2 reliable and valid 7-item Likert scales used to assess severity and change in clinical symptoms. The CGI severity scale (CGI-TS-S) ranges from 1 = "not ill at all" to 7 = "among the most extremely ill." Higher scores represent more severe symptoms. A negative change from baseline indicates improvement.
SecondaryClinical Global Impression Tourette Syndrome of Improvement (CGI-TS-I) Scores at Months 1, 3, 6, 9 and 12Months 1, 3, 6, 9 and 12
The CGI consists of 2 reliable and valid 7-item Likert scales used to assess severity and change in clinical symptoms. The scale ranges from 1 = "very much improved" to 7 = very much worse" for the CGI-TS-I. Higher score represent more severe symptoms.
SecondaryChange From Baseline in Gilles de la Tourette Syndrome-Quality of Life Scale for Children and Adolescents (C&A-GTS-QOL) Total Score at Months 1, 3, 6, 9 and 12Baseline up to Months 1, 3, 6, 9 and 12
The C\&A-GTS-QOL was a 27-item questionnaire specific to TS patients that asks the patient to assess the extent to which their quality of life is impacted by their symptoms. The C\&A-GTS-QOL consists of 6 subscales (cognitive \[score range 0-32\], coprophenomena \[range 0-12\], psychological \[range 0-24\], physical \[range 0-12\], obsessive-compulsive \[range 0-16\], and activities of daily living (ADL) \[range 0-12\] and uses a 5 point Likert scale ranging from no problem to extreme problem. Scores for six subscales were generated by summing items and, for ease of interpretation, transformation to a range of 0 to 100 (100\* \[(observed score-min possible score)/(max possible score-min possible score)\]). Total score, resulted from sum of the subscale scores, was also normalized to a 0 to 100 range. Higher score indicated worst quality of life. A negative change from baseline indicates better quality of life.
