Change From Baseline to Week 8 in the YGTSS TTS
Lasso di tempo: Baseline, Week 8
|
The YGTSS is designed to rate the overall severity of motor and phonic tic symptoms across a range of dimensions: number, frequency, intensity, complexity, and interference.
The YGTSS was administered by the investigator (or qualified designee) using a computer-based structured clinical interview.
The TTS is the sum of the 5 motor tic items and the 5 phonic (vocal) tic items and ranges from 0 to 50, with higher scores representing greater severity

Clinical Global Impression of Change Tourette Syndrome (CGI-TS)-Improvement Score at Week 8
Lasso di tempo: Week 8
|
The CGI-TS-Improvement scale is used to assess overall improvement since the initiation of study drug dosing on a 7-point scale.
Each of the CGI-TS-Improvement response categories was assigned a numerical score as follows: 1 = Very much improved; 2 = Much improved; 3 = Minimally improved; 4 = Not changed; 5 = Minimally worse; 6 = Much worse; 7 = Very much worse.

Week 8
|
|
Change From Baseline to Week 8 in the Clinical Global Impression of Tics (CGI-Tics)-Severity Score
Lasso di tempo: Baseline, Week 8
|
The CGI-Tics-Severity scale is used to assess overall severity on a 7-point scale.
Each of the CGI-Tics-Severity response categories was assigned a numerical score as follows: 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 patient.

Change From Baseline to Last Visit in the Rush Video-based Tic Rating Scale (RTRS) Total Score
Lasso di tempo: Baseline, Week 8
|
A modified RTRS was used in this study that includes short video recordings to measure 5 tic variables: number of body areas affected, frequency of motor and phonic tics, and severity of motor and phonic tics.
The RTRS total score is calculated as the sum of the 5 domain scores, and ranges from 0 to 20, with higher scores representing greater severity.
The final on-treatment visit was used in subjects who discontinued prior to Week 8.

|
|
Change From Baseline to Week 8 in the YGTSS Global Tic Severity Score
Lasso di tempo: Baseline, Week 8
|
The YGTSS Global Tic Severity score is the sum of the YGTSS TTS and the YGTSS Impairment score and ranges from 0 to 100, with higher scores representing greater severity.
|
Baseline, Week 8
|
|
Change From Baseline to Week 8 in the Premonitory Urge for Tics Scale (PUTS) Total Score
Lasso di tempo: Baseline, Week 8
|
The PUTS is an instrument for quantifying the premonitory urge phenomena associated with tics.
It consists of 9 items, each of which is scored on a 4-point scale (1=not at all true, 2=a little true, 3=pretty much true, 4=very much true).
The PUTS total score is calculated as the sum of the scores for the 9 items.
The maximum possible total score is 36.
