Data from the Open-label KINECT 4 Phase III Study to be Presented as an Oral Hot Topic

SAN DIEGO, Nov. 29, 2017 /PRNewswire/ -- Neurocrine Biosciences, Inc. (NASDAQ: NBIX) today announced that new long-term

data from the open-label KINECT 4 Phase III study of INGREZZA® (valbenazine) capsules, the first FDA approved treatment for adults with tardive dyskinesia (TD), will be presented at the Hot Topics Session at the American College of Neuropsychopharmacology (ACNP) Annual Meeting December 3-7 in Palm Springs, California.

"Neurocrine is committed to helping patients who struggle with both tardive dyskinesia and their psychiatric condition," said Christopher O'Brien, M.D., Chief Medical Officer of Neurocrine Biosciences. "These new data, combined with additional sub-group analyses from the INGREZZA clinical program, will help neurologists and psychiatrists further understand the role of INGREZZA for the treatment of uncontrollable, abnormal and repetitive movements of the trunk, extremities and face."

The four Neurocrine-related abstracts, including the abstract being presented at the Hot Topics Session, at the ACNP Annual Meeting are:

  • KINECT 4: A Phase 3, One-Year, Open-Label Trial of Valbenazine in Participants with Tardive Dyskinesia (T159)Hot Topics Session: Sunday, Dec. 3, 2:30-2:45 p.m.Poster Session: Tuesday, Dec. 5, 5:30-7:30 p.m.
  • Effects of Valbenazine on Prolactin in Adults with Tardive Dyskinesia: Pooled Results from 3 Randomized, Double-Blind, Placebo-Controlled Trials (M149)Poster Session I: Monday, Dec. 4, 5:30-7:30 p.m.
  • Can Presynaptic and Postsynaptic Monoaminergic Mechanisms Work Synergistically? Current Findings and Future Directions (T224)Poster Session II: Tuesday, Dec. 5, 5:30-7:30 p.m.
  • Valbenazine in Tardive Dyskinesia of Older and Younger Adults: Pooled Results from 3 Randomized, Double-Blind, Placebo-Controlled Trials (W152)Poster Session III: Wednesday, Dec. 6, 5:30-7:30 p.m.

About Tardive Dyskinesia (TD)Tardive dyskinesia (TD) is characterized by uncontrollable, abnormal and repetitive movements of the trunk, extremities and/or face. The condition is associated with 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 may 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) CapsulesINGREZZA, 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 trunk, extremities and/or face.

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. INGREZZA is currently in clinical development for the treatment of Tourette syndrome.

Important Safety InformationWarnings & PrecautionsSomnolence 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 ProlongationINGREZZA 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.

Adverse ReactionsThe 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.
