|
Number of Participants Monitored for Long-term Safety of Valbenazine
Time Frame: 60 weeks
|
Incidence of adverse events and monitoring of vital signs, clinical laboratory values, and electrocardiograms.
All AEs were coded into preferred terms according to MedDRA (Medical Dictionary for Regulatory Activities) and classified by system organ class (SOC).
Summaries of the incidence of all treatment-emergent AEs, treatment-related AEs, SAEs, and AEs leading to study drug discontinuation were prepared.

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Number of Participants With Clinical Response as Assessed by the Clinical Global Impression of Tardive Dyskinesia - Severity (CGI-TD-Severity) Scale
Time Frame: Baseline and Weeks 12, 24, 36, 48, and 60
|
Clinician's perspective of the participant's overall severity of TD symptoms.
The CGI-TD-Severity is based on a 7-point scale (range: 1= "Normal, not at all ill" to 7= "Among the most extremely ill patient").
A clinical response was defined as a CGI-TD-S score equal to "1" or "2."
|
Baseline and Weeks 12, 24, 36, 48, and 60
|
|
Number of Participants With Clinical Response as Assessed by the Patient Satisfaction Questionnaire (PSQ)
Time Frame: Baseline and Weeks 12, 24, 36, 48, and 60
|
Participant's perspective of his/her satisfaction with valbenazine treatment.
The PSQ is based on a 5-point scale (range: 1=very satisfied to 5=very dissatisfied).
A clinical response was defined as a PSQ score equal to "1" or "2."
|
Baseline and Weeks 12, 24, 36, 48, and 60
