Neurocrine Biosciences Publishes Analysis Showing Long-Term Efficacy and a Consistent Safety Profile of INGREZZA® (valbenazine) Capsules in Older Adults with Tardive Dyskinesia in The Journal of Clinical Psychiatry

Post-hoc analysis of higher risk older adults showed substantial and sustained improvements in tardive dyskinesia symptoms with no new treatment-emergent adverse events of clinical concern

SAN DIEGO, April 24, 2025 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced publication of a post-hoc analysis from two 48-week studies, the KINECT® 3 extension and KINECT® 4, demonstrating the long-term safety profile and robust efficacy of INGREZZA® (valbenazine) capsules in adults aged 65 years and older with tardive dyskinesia (TD) in The Journal of Clinical Psychiatry. This represents the first and only published peer-reviewed analysis of a vesicular monoamine transporter 2 inhibitor for the treatment of TD in older adults (≥65 years), a group at higher risk for TD and associated consequences.

Individuals aged 60 years and older may develop TD after as little as one month of exposure to antipsychotics and other dopamine receptor blocking agents. The involuntary movements of TD can also have a substantial impact on older adults, affecting their balance, gait, ability to swallow and respiratory conditions. The data from this post-hoc analysis show substantial and sustained improvements in TD symptoms in older adults, with no new treatment-emergent adverse events of clinical concern found when compared with younger adults (
