Neurocrine Biosciences Presents New INGREZZA® (valbenazine) Data at Psych Congress 2021


SAN DIEGO, Nov. 1, 2021 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today announced that it presented new data from its movement disorder program for tardive dyskinesia (TD) at the 2021 Psych Congress scientific meeting being held October 29–November 1, 2021.

Key highlights include:

  • New pooled analysis from the KINECT clinical trial program and long-term extension studies found that long-term use of INGREZZA® (valbenazine) led to substantial and clinically meaningful improvements in patients ≥ 65 years with tardive dyskinesia, some of the first TD-specific vesicular monoamine transporter 2 (VMAT2) inhibitor data for this age group.
  • Presentation of the development of the MIND-TD questionnaire, a novel online questionnaire to help facilitate dialogue between healthcare professionals and patients about the risks, symptoms and impact of TD.
  • New real-world data from TeleSCOPE, an observational study, showed that the use of telehealth during the COVID-19 pandemic significantly reduced clinicians' abilities to diagnose, assess, monitor and treat drug-induced movement disorders.
  • Characterization of the in vitro activity and pharmacokinetic profile of INGREZZA compared to deutetrabenazine confirms a single, specific, potent INGREZZA metabolite with strong VMAT2 affinity and supports once-daily dosing for INGREZZA.

"Presentation of these new data analyses at this year's Psych Congress will continue to help psychiatric healthcare providers further understand the role of INGREZZA in helping people living with tardive dyskinesia," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "These analyses also reflect our continued commitment to provide valuable resources to patients, caregivers and the healthcare community focused on awareness, screening and treatment of tardive dyskinesia."

About Tardive Dyskinesia (TD)
Tardive dyskinesia (TD) is an involuntary movement disorder characterized by uncontrollable, abnormal and repetitive movements of the torso, extremities and/or face, which can include hand or foot movements, rocking of the torso, lip smacking, grimacing, tongue protrusion, facial movements or blinking, as well as puckering and pursing of the lips. The condition is associated with taking certain mental health medicines such as antipsychotics, which are commonly prescribed to treat mental illnesses such as bipolar disorder, depression and schizophrenia. 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. 

Important Information

Approved Use 

INGREZZA® (valbenazine) capsules is a prescription medicine used to treat adults with movements in the face, tongue, or other body parts that cannot be controlled (tardive dyskinesia). 

It is not known if INGREZZA is safe and effective in children. 


Do not take INGREZZA if you:

  • are allergic to valbenazine, or any of the ingredients in INGREZZA.
