Measure Description:

The Brief Psychiatric Rating Scale (BPRS) assesses the severity of psychopathology in patients with schizophrenia and other psychotic disorders by addressing 18 items. The severity of each item is rated on a scale of 1 (not present) to 7 (extremely severe) (total score range: 18 to 126). Higher scores represent greater symptom severity.

The Clinical Global Impression of Tardive Dyskinesia-Severity (CGI-TD-severity) scale assesses the overall global severity of TD. The scale has 7 points from 1=normal, not at all ill to 7=among the most extremely ill patient.

[2]
Measure Analysis Population Description: Baseline CGI-TD-Severity Score is not available for one participant in the 80 mg valbenazine oral capsule treatment arm.
1.Primary Outcome
Title Number of Participants Monitored for Long-term Safety of Valbenazine
Hide Description 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.

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
Generally, the PI has the right to publish results provided such publication does not violate confidentiality or IP provisions within the contract with the Sponsor. Prior to submission for publication or presentation of results, the PI must provide the Sponsor time for review. The Sponsor can request the PI to withhold or remove information from all publications. For a multi-center study, any publication of results by the PI shall not be made before the first multi-center publication.
