Trial Outcomes & Findings for Rollover Study for Continuing Valbenazine (NBI-98854) Administration for the Treatment of Tardive Dyskinesia (NCT NCT02736955)

NCT ID: NCT02736955

Last Updated: 2018-12-19

Results Overview

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.

Valbenazine 40 mg
Participants received 40 mg valbenazine oral capsule once daily for up to 60 weeks
Valbenazine 80 mg
Participants received 40 mg valbenazine oral capsule once daily for 4 weeks, followed by 80 mg (provided as 2 x 40 mg valbenazine oral capsule) once daily for up to 56 weeks
Valbenazine 40/80 mg
Participants received 40 mg valbenazine oral capsule once daily for 4 weeks. Participants were then increased to 80 mg (provided as 2 x 40 mg valbenazine oral capsule) once daily, and due to poor tolerance, were subsequently reduced back to one 40 mg valbenazine oral capsule once daily for the remainder of the study, up to 56 weeks

SECONDARY outcome

Timeframe: Baseline and Weeks 12, 24, 36, 48, and 60

Population: Safety analysis set: includes all participants who were enrolled in the study and received study drug, with the following two exclusions: (a) participants who withdrew from the study and returned all previously dispensed study drug with all doses present, and (b) participants who had no post-baseline data collected.

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."
