Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Monitored for Long-Term Safety of Valbenazine	Number of participants monitored for long-term safety through reporting of treatment-emergent adverse events and monitoring of vital signs, clinical laboratory values, and ECG. Summaries of all treatment-emergent AEs, treatment-related AEs, SAEs, and AEs leading to study drug discontinuation were prepared.	52 weeks
Secondary	Severity of Tardive Dyskinesia (TD) Symptoms Assessed by Abnormal Involuntary Movements Scale (AIMS) Dyskinesia Total Score Change From Baseline at Week 48; On-site AIMS Raters	Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by On-Site AIMS video 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 48
Secondary	Severity of Tardive Dyskinesia (TD) Symptoms Assessed by Abnormal Involuntary Movements Scale (AIMS) Dyskinesia Total Score Change From Baseline; Central AIMS Video Raters	Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by the blinded, Central AIMS Video 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, Change from Baseline at Week 8, and Change from Baseline at Week 52
Secondary	Severity of Tardive Dyskinesia (TD) Symptoms Assessed by Abnormal Involuntary Movements Scale (AIMS) Dyskinesia Total Score Change From Baseline; On-Site AIMS Raters	Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by On-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, Change from Baseline at Week 8, and Change from Baseline at Week 52
Secondary	Clinical Global Impression - Global Improvement of Tardive Dyskinesia (CGI-TD) at Week 48	Clinician's perspective of the participant's overall improvement of TD symptoms since initiation of study drug dosing. The CGI-TD is based on a 7-point scale (range: 1=very much improved to 7=very much worse).	Week 48
