Neurocrine Biosciences to Present Data Analyses Demonstrating the Long-Term Effectiveness of INGREZZA® (valbenazine) in Patients with Tardive Dyskinesia at the 2019 Annual Psych Congress

SAN DIEGO, Oct. 1, 2019 /PRNewswire/ -- Neurocrine Biosciences, Inc. (NASDAQ: NBIX) today announced it will present data analyses evaluating the long-term effects of once-daily 40 mg INGREZZA^® (valbenazine) in adults with tardive dyskinesia (TD), an involuntary movement disorder. A data analysis will also be presented on the long-term effects of INGREZZA in patients who demonstrated improvement in TD symptoms as early as two weeks. In addition, Neurocrine Biosciences will present data on the impact possible TD has on a patient's health-related quality of life from RE-KINECT, the largest real-world screening study of patients with clinician-confirmed possible TD. These data will be presented at the 2019 Annual Psych Congress in San Diego, Oct. 3-6, 2019.

"We look forward to presenting data at Psych Congress which will provide further insight into the long-term benefits of INGREZZA for the treatment of tardive dyskinesia, including the effectiveness of the 40 mg dose and the impact of early response to treatment," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "These data provide important clinical information on how INGREZZA can help to manage involuntary movements in patients, and data from our real-world screening study can increase our understanding of the social, physical and emotional impact these movements may have on the everyday lives of patients." 

INGREZZA is the first U.S. Food and Drug Administration (FDA) approved treatment for adults with TD, a movement disorder that is characterized by uncontrollable, abnormal and repetitive movements of the face, torso and/or other body parts. The abnormal and involuntary movements of TD can impact patients socially, emotionally and physically, causing patients to feel embarrassed or judged by others or withdraw from society and isolate themselves.

The three Neurocrine-sponsored abstracts that will be presented at the 2019 Annual Psych Congress are:

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 caused by prolonged use of treatments that block dopamine receptors in the brain, such as antipsychotics commonly prescribed to treat mental illnesses such as schizophrenia, bipolar disorder and depression, and certain anti-nausea medications. 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 at least 500,000 people in the U.S.

About INGREZZA^® (valbenazine) Capsules
INGREZZA, a selective vesicular monoamine transporter 2 (VMAT2) inhibitor, is the first 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 in Neurocrine's laboratories, 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 psychiatric medications such as antipsychotics or antidepressants.

Important Safety Information

Contraindications
INGREZZA is contraindicated in patients with a history of hypersensitivity to valbenazine or any components of INGREZZA. Rash, urticaria, and reactions consistent with angioedema (e.g., swelling of the face, lips, and mouth) have been reported.

Warnings & Precautions 
Somnolence 
INGREZZA can cause somnolence. Patients should not perform activities requiring mental alertness such as operating a motor vehicle or operating hazardous machinery until they know how they will be affected by INGREZZA.

QT Prolongation 
INGREZZA may prolong the QT interval, although the degree of QT prolongation is not clinically significant at concentrations expected with recommended dosing. INGREZZA should be avoided in patients with congenital long QT syndrome or with arrhythmias associated with a prolonged QT interval. For patients at increased risk of a prolonged QT interval, assess the QT interval before increasing the dosage.

Parkinsonism
INGREZZA may cause parkinsonism in patients with tardive dyskinesia. Parkinsonism has also been observed with other VMAT2 inhibitors. Reduce the dose or discontinue INGREZZA treatment in patients who develop clinically significant parkinson-like signs or symptoms.

Adverse Reactions 
The most common adverse reaction (≥5% and twice the rate of placebo) is somnolence. Other adverse reactions (≥2% and >placebo) include: anticholinergic effects, balance disorders/falls, headache, akathisia, vomiting, nausea, and arthralgia.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit MedWatch at www.fda.gov/medwatch or call 1-800-FDA-1088.
