Neurocrine Biosciences to Present Data on INGREZZA® (valbenazine) and Opicapone at the 2018 World Congress on Parkinson's Disease and Related Disorders

SAN DIEGO, Aug. 15, 2018 /PRNewswire/ -- Neurocrine Biosciences, Inc. (NASDAQ: NBIX) today announced it will present data from its movement disorders programs, including additional long-term results for INGREZZA^® (valbenazine) capsules, the first U.S. Food and Drug Administration (FDA) approved treatment for adults with tardive dyskinesia (TD), and data analyses from a Phase III study on opicapone, an investigational treatment for Parkinson's disease. These results will be presented at the 2018 World Congress on Parkinson's Disease and Related Disorders (IAPRD) in Lyon, France, Aug. 19-22, 2018.

"Neurocrine Biosciences is committed to bringing innovative and effective treatments to patients living with movement disorders," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "We look forward to providing additional analyses of INGREZZA's long-term efficacy in tardive dyskinesia, as well as findings from the Phase III BIPARK-I study of opicapone in Parkinson's disease. We believe these results will help healthcare providers further understand the benefits of INGREZZA and the potential of opicapone to help patients suffering from these serious, and often isolating, movement disorders."

Highlighted poster presentations on INGREZZA include data from two long-term studies examining the treatment's safety and efficacy over 48 weeks in patients with tardive dyskinesia, including patient-reported outcome results from the Phase III KINECT 4 study and an open-label, rollover trial reporting on symptom improvement and patient satisfaction with treatment.

Neurocrine will also present three analyses on opicapone from the Phase III BIPARK-I study highlighting the efficacy and safety of once-daily opicapone treatment in patients with Parkinson's disease, compared to placebo and entacapone. Primary outcomes from the BIPARK-I study were previously published in Lancet Neurology, with the outcomes from the open-label extension phase of the BIPARK-I study subsequently published in Neurology.

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 caused by 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 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.

Important Safety Information

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.

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.

About Parkinson's Disease
Parkinson's disease is a chronic and progressive movement disorder that affects approximately one million people in the United States. The disease is characterized by a loss of neurons in the substantia nigra, the area of the brain where dopamine is produced. Dopamine production and synthesis is necessary for coordination and movement. As Parkinson's progresses, dopamine production steadily decreases resulting in slowed movement (bradykinesia), tremor, rigidity, impaired posture and balance, and speech and writing problems. There is no present cure for Parkinson's disease and management consists of controlling the motor symptoms primarily through administration of levodopa therapies. While this improves the control of Parkinson's motor symptoms, the disease progresses, and the beneficial effects of levodopa begin to wear off, symptoms worsen and patients experience end-of-dose motor fluctuations. These end-of-dose motor fluctuations can be improved by the addition of a catechol-o-methyltransferase (COMT) inhibitor to levodopa.

About Opicapone
Opicapone, an investigational treatment for Parkinson's disease, is a novel, once-daily, peripherally-acting, selective catechol-o-methyltransferase (COMT) inhibitor proposed for use as adjunct therapy to levodopa/DOPA decarboxylase inhibitors in Parkinson's patients experiencing motor fluctuations. Opicapone works by prolonging the duration of effect of levodopa through decreasing its conversion rate into 3-O-methyldopa. A novel compound discovered in the BIAL – Portela & CA, S.A. (BIAL) laboratories, it is designed to provide patients and physicians with a once-daily option for the treatment of Parkinson's disease.

In June 2016, the European Commission authorized ONGENTYS^® (opicapone) as an adjunct therapy to preparations of levodopa/DOPA decarboxylase inhibitors (DDCIs) in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilized on those combinations. This European approval was based on data from a clinical development program that included 28 clinical studies of more than 900 patients treated with opicapone in 30 countries worldwide. Opicapone is an investigational drug, not approved for use in the United States or Canada.
