MT-5199 40 mg (Double-Blind Extension Period)MT-5199At the end of Week 6, subjects will enter a double-blind extension period for 42 weeks. Subjects who were initially randomized to placebo will be re-randomized (1:1) to receive either MT-5199 40 mg or 80 mg and subjects initially randomized to MT-5199 will continue with their current dose.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score (Central Assessment) at Week 6Baseline 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.

Secondary Outcome Measures
NameTimeMethod
Percentage of Subjects With a ≥50% Improvement From Baseline in the AIMS Total Score (Central Assessment) at Week 6 (AIMS Responder)Week 6

Percentage of AIMS responders (subjects who had at least a 50 percent reduction in AIMS score from baseline)

Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score (Site Assessment) at Week 6Baseline 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.

Clinical Global Impression of Change - TD (CGI-TD) Score at Week 6Week 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).
