Neurocrine Biosciences Identifier:
First received: November 20, 2012
Last updated: November 20, 2014
Last verified: November 2014
The purpose of this study is to evaluate the efficacy, safety, and tolerability of NBI-98854 (titrated to a subject's optimal dose in the range of 25 to 75 mg) administered once daily for the treatment of Tardive Dyskinesia (TD) symptoms.

Condition Intervention Phase
Tardive Dyskinesia
Drug: NBI-98854
Drug: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Dose-Titration Study to Assess the Safety, Tolerability, and Efficacy of NBI-98854 for the Treatment of Tardive Dyskinesia

Further study details as provided by Neurocrine Biosciences:

Primary Outcome Measures:
  • Severity of tardive dyskinesia (TD) symptoms assessed by Abnormal Involuntary Movements Scale (AIMS) [ Time Frame: Baseline ]
  • Severity of TD symptoms assessed by AIMS [ Time Frame: Week 2 ]
    Change from Baseline, Proportion of responders based on reduction from baseline

  • Severity of TD symptoms assessed by AIMS [ Time Frame: Week 4 ]
    Change from Baseline, Proportion of responders based on reduction from baseline

  • Severity of TD symptoms assessed by AIMS [ Time Frame: Week 6 ]
    Change from Baseline, Proportion of responders based on reduction from baseline

Secondary Outcome Measures:
  • Clinical global impression - global improvement of TD (CGI-TD) [ Time Frame: Weeks 2 and 6 ]
    Clinician's perspective of the participant's overall improvement of TD symptoms over time

  • Number of Participants with Adverse Events following dosing with NBI-98854 [ Time Frame: Up to 14 weeks ]
    Proportion of subjects reporting adverse events

  • Evaluation of plasma concentrations of NBI-98854 and metabolites following repeated daily doses of NBI-98854 [ Time Frame: Weeks 2 and 6 ]
    Plasma samples will be collected and analyzed to evaluate drug and metabolite plasma concentrations.

Other Outcome Measures:
  • Exploratory efficacy assessment of NBI-98854 administered once daily for the treatment of tardive dyskinesia (TD) symptoms [ Time Frame: Week 6 ]
    Patient Global Impression of Change (PGIC) questionnaire.

  • Exploratory efficacy assessment of NBI-98854 administered once daily for the treatment of tardive dyskinesia (TD) symptoms [ Time Frame: Baseline; Weeks 2 and 6 ]
    Tardive Dyskinesia Ratings Scale (TDRS)

Enrollment: 102
Study Start Date: December 2012
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: NBI-98854
Dose titration to determine a subject's optimal dose in the range of 25 to 75 mg NBI-98854. Dose titration is performed in increments of 25 mg. NBI-98854 administered as one (1) 25 mg capsule, two (2) 25 mg capsules, or one (1) 25 mg capsule and one (1) 50 mg capsule by mouth, taken every morning between 7:00am - 10:00am for 6 weeks.
Drug: NBI-98854
25 mg capsule
Drug: NBI-98854
50 mg capsule
Placebo Comparator: Placebo
Capsule containing no active substance, manufactured to mimic NBI-98854 25 mg and 50 mg capsules.
Drug: Placebo

Detailed Description:

This is a Phase 2, randomized, double-blind, placebo-controlled, dose-titration study to evaluate the efficacy, safety, and tolerability of NBI-98854 (titrated to subject's optimal dose in the range of 25 to 75 mg) compared to placebo, administered once daily (q.d.) for a total of 6 weeks of treatment. Approximately 90 medically stable male and female subjects with one of the following clinical diagnoses will be enrolled: schizophrenia or schizoaffective disorder with neuroleptic-induced TD; mood disorder with neuroleptic-induced TD; or gastrointestinal disorder with metoclopramide-induced TD.

For subjects randomized to active treatment, the starting dose will be 25 mg NBI 98854, which may be escalated in increments of 25 mg every 2 weeks to a maximum of 75 mg to achieve an optimal dose of NBI-98854 for each subject


Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:
