Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score (Central Assessment) at Week 6
Time Frame: Baseline and Week 6
Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by blinded central AIMS raters. The AIMS Total Dyskinesia Score rates a total of 7 items, rating involuntary movement from 0 (no dyskinesia) to 4 (severe dyskinesia). Items 1 through 7 include facial and oral movements (Items 1-4), extremity movements (Items 5-6), and trunk movements (Item 7). The AIMS dyskinesia total score for Items 1-7 ranges from 0 to 28; a higher score reflects increased severity.
Baseline and Week 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Subjects With a ≥50% Improvement From Baseline in the AIMS Total Score (Central Assessment) at Week 6 (AIMS Responder)
Time Frame: Week 6
Percentage of AIMS responders (subjects who had at least a 50 percent reduction in AIMS score from baseline)
Week 6
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score (Site Assessment) at Week 6
Time Frame: Baseline and Week 6
Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by blinded site AIMS raters. The AIMS Total Dyskinesia Score rates a total of 7 items, rating involuntary movement from 0 (no dyskinesia) to 4 (severe dyskinesia). Items 1 through 7 include facial and oral movements (Items 1-4), extremity movements (Items 5-6), and trunk movements (Item 7). The AIMS dyskinesia total score for Items 1-7 ranges from 0 to 28; a higher score reflects increased severity.
Baseline and Week 6
Clinical Global Impression of Change - TD (CGI-TD) Score at Week 6
Time Frame: Week 6
Clinician's perspective of the participant's overall improvement of TD symptoms over time. The CGI-TD is based on a 7-point scale (range: 1=very much improved to 7=very much worse).
