Trial Outcomes & Findings for A Phase 3 Study of NBI-98854 for the Treatment of Tardive Dyskinesia (NCT NCT02274558)

NCT ID: NCT02274558

Last Updated: 2017-07-11

Results Overview

Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by 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.

PRIMARY outcome

Timeframe: Baseline and Week 6

Population: Intent to treat (ITT) analysis set (all subjects in the safety analysis set who have a baseline (Day -1) AIMS dyskinesia total score value and at least one post-randomization AIMS dyskinesia total score value reported during the placebo-controlled treatment period).

Severity of TD symptoms assessed by AIMS dyskinesia total score (sum of items 1 through 7), as assessed by 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.
