Primary Outcome Measures

Name	Time	Method
Treatment-emergent adverse event	From baseline to Week 8	Number of participants with treatment-emergent adverse event will be summarized by Group, System Organ Classification (SOC), Preferred Term (PT), severity and the relationship with treatment.
Change in Abnormal Involuntary Movement Scale (AIMS) Dyskinesia Total Score	From baseline to Week 8	Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by blinded 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

Name	Time	Method
The proportion of subjects who have a 50% improvement in AIMS Dyskinesia Total Score	From baseline to Week 8
Clinical Global Impression - Global Improvement of TD (CGI-TD)	From Week 2 to Week 8
Patient Global Impression of Change (PGIC)	From Week 2 to Week 8
Maximum observed concentration (Cmax)	From predose to 24 hours of day 1
Area Under the Curve from time 0 to 24 hours of day 1 (AUC0-24h)	From predose to 24 hours of day 1
Concentration at the end of the dosing interval at steady state (Cτ,ss)	Predose on Day 14±2, Day 28±2 and Day 42±2
