Neurocrine Biosciences Presents New INGREZZA® (valbenazine) Data on Tardive Dyskinesia Improvement and Stability of Psychiatric Symptoms at American Psychiatric Association Annual Meeting 2022

SAN DIEGO, May 23, 2022 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced that it will present data on the use of INGREZZA^® (valbenazine) capsules for the treatment of tardive dyskinesia (TD) at the American Psychiatric Association (APA) Annual Meeting being held in person May 21-25 in New Orleans and virtually June 7-10.

Neurocrine Biosciences, the leading neuroscience-focused company in the treatment of TD, will present findings from a post hoc analysis of two long-term studies of INGREZZA evaluating global TD improvement and stability of psychiatric symptoms (Poster title: Poster #P7-088 Global Improvements and Psychiatric Stability in Adults with Tardive Dyskinesia: Post Hoc Analyses of Two Long-Term Valbenazine Studies). The analysis found that long-term treatment (48 weeks) for TD with once-daily INGREZZA (40 mg or 80 mg) resulted in substantial clinician-rated and self-rated global improvements of TD symptoms while stability of psychiatric symptoms was maintained, regardless of the participant’s primary psychiatric condition.

“The findings presented at the APA Annual Meeting provide further insight into aspects of tardive dyskinesia management that are important to patients,” said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. “Treatment of TD symptoms often requires consideration of complex psychiatric conditions. These data demonstrate that stability of psychiatric symptoms is maintained during TD treatment with valbenazine.”

Additional presentations include:

• Synergy Between VMAT2 Inhibitors and Antipsychotics in Animal Models of Schizophrenia (Poster #P5-080)
• TeleSCOPE: A 2021 Clinician Survey on Telehealth Services to Detect and Treat Tardive Dyskinesia in the Psychiatry and Neurology Outpatient Setting (#Poster P8-079)
• A Novel, Web-Based Patient-Centric Study to Evaluate the Impact of Treatment of Tardive Dyskinesia with Valbenazine: The RxKinect Study (#Poster P8-031)

A full list of all abstracts being presented by Neurocrine Biosciences at the 2022 APA Annual Meeting is available in the poster proceedings on the Annual Meeting Website.

About Tardive Dyskinesia (TD)
Tardive dyskinesia (TD) is a movement disorder that is characterized by uncontrollable, abnormal, and repetitive movements of the face, torso and/or other body parts, which may be disruptive and negatively impact patients. The condition is associated with taking certain kinds of mental health medicines (like antipsychotics) that help control dopamine receptors in the brain. Taking antipsychotics commonly prescribed to treat mental illnesses such as depression, bipolar disorder, schizophrenia and schizoaffective disorder, and certain medications to treat upset stomach, nausea and vomiting are associated with TD. In patients with TD, these treatments are thought to result in irregular dopamine signaling in a region of the brain that controls movement. The symptoms of TD can be severe and are often persistent and irreversible. TD is estimated to affect approximately 600,000 people in the U.S.

About INGREZZA^® (valbenazine) Capsules
INGREZZA, a selective vesicular monoamine transporter 2 (VMAT2) inhibitor, is an FDA-approved product indicated for the treatment of adults with tardive dyskinesia, a condition associated with uncontrollable, abnormal, and repetitive movements of the face, torso and/or other body parts.

INGREZZA is thought to work by reducing the amount of dopamine released in a region of the brain that controls movement and motor function, helping to regulate nerve signaling in adults with tardive dyskinesia. VMAT2 is a protein in the brain that packages neurotransmitters, such as dopamine, for transport and release in presynaptic neurons. INGREZZA, developed by Neurocrine Biosciences, is novel in that it selectively inhibits VMAT2 with no appreciable binding affinity for VMAT1, dopaminergic (including D2), serotonergic, adrenergic, histaminergic, or muscarinic receptors. Additionally, INGREZZA can be taken for the treatment of tardive dyskinesia as one capsule, once-daily, together with most psychiatric medications such as antipsychotics or antidepressants.
