Neurocrine Biosciences, Inc. (NASDAQ: NBIX) announced today that NBI-98854, a highly selective small molecule VMAT2 inhibitor, showed a statistically significant reduction in tardive dyskinesia during the six weeks of placebo-controlled treatment in the Kinect 3 clinical trial. This Phase III trial included moderate to severe tardive dyskinesia patients with underlying schizophrenia, schizoaffective disorder, bipolar or major depressive disorder.
The pre-specified primary efficacy endpoint was the change-from-baseline in the Abnormal Involuntary Movement Scale (AIMS) at Week 6 in the 80mg once-daily dosing group compared to placebo as assessed by central blinded video raters. The AIMS ratings at Week 6 for the 80mg once-daily NBI-98854 intention-to-treat (ITT) population was reduced 3.1 points (Least-Squares Mean) more than placebo (p<0.0001).
“We are very pleased with the outstanding efficacy and side effect profile demonstrated by NBI-98854 in the Kinect 3 study. The efficacy data from this pivotal Phase III study completes our placebo-controlled dataset for NBI-98854 in tardive dyskinesia,” said Kevin C. Gorman, President and Chief Executive Officer of Neurocrine. “We will now turn our focus to completing the open-label safety portion of the studies in tardive dyskinesia patients and compiling the data for both doses of NBI-98854 to be included in the New Drug Application we intend to file with the FDA in 2016.”
