Official Title
A Phase 2b, Randomized, Double-Blind, Placebo-Controlled, Dose Optimization Study to Assess the Safety, Tolerability, and Efficacy of NBI-98854 for the Treatment of Pediatric Subjects With Tourette Syndrome
Primary Outcomes
Outcome Description
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.
Outcome Measure
Change From Baseline to Week 12 in the Yale Global Tic Severity Scale (YGTSS) Total Tic Score (TTS)
Outcome Time Frame
Baseline, Week 12
Secondary Outcomes
Outcome Description
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.
Outcome Time Frame
Baseline, Week 12
Outcome Measure
Change From Baseline to Week 12 in the Clinical Global Impression of Tics Severity (CGI-Tics-Severity) Score
Outcome Description
A TTS responder is defined, on a per-visit basis, as a participant whose TTS value is reduced by at least 30% from baseline at the specified postbaseline visit.
Outcome Time Frame
Baseline, Week 12
Outcome Measure
Participants Who Are a Yale Global Tic Severity Scale (YGTSS) Total Tic Score (TTS) Responder at Week 12
Outcome Description
The CGI-TS-Improvement scale is used to assess overall improvement since the initiation of study drug dosing on a 7-point scale. A CGI-TS-Improvement responder is defined, on a per-visit basis, as a participant whose CGI-TS-Improvement score is 1 ("Very much improved") or 2 ("Much improved") at the specified postbaseline visit.
Outcome Time Frame
Week 12
Outcome Measure
Participants Who Are a Clinical Global Impression of Tourette Syndrome Improvement (CGI-TS-Improvement) Responder at Week 12
