SAN DIEGO , June 6, 2022 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX ) today presents data on sleep disturbances in Parkinson's disease (PD) demonstrating the impact of OFF episodes, or reemergence of symptoms between doses of levodopa, on falling asleep and staying asleep. These data (abstract ID: 0581) are being shared at SLEEP 2022 , the annual meeting of the Associated Professional Sleep Societies, LLC (APSS) being held June 4-8 in Charlotte, North Carolina . The oral presentation of these data will take place on June 8 at 2:15 p.m. (oral presentation session: O-28).
"Sleep disturbances in individuals with Parkinson's disease can significantly impact health, mood, and quality of life," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "These data provide insight on the impact of OFF episodes and their contribution to sleep disturbances, both in falling asleep and staying asleep. At Neurocrine Biosciences, we are committed to furthering understanding of the wide-ranging effects of movement disorders to elevate care for the patients we serve."
The post-hoc analyses were conducted using baseline data from two previous Phase 3 studies of ONGENTYS ® (opicapone) capsules , an approved once-daily adjunctive treatment to levodopa/carbidopa (LD/CD) in patients with PD experiencing OFF time.
Results of this post-hoc analysis indicate that 34.4% (332/964) of participants experienced an OFF episode before going to sleep for a mean duration of 1.8±1.2 hours. Among participants who woke up during the night (16.4%, 158/964), 81.0% (128/158) were in an OFF state for a mean duration of 1.0 (±0.5) hours. Additionally, 89.4% (898/1005) of participants experienced an OFF episode upon waking in the morning, with the mean duration of this time to morning "ON" episode being 1.5 (±0.9) hours. OFF episodes can contribute to sleep impairment, a common but poorly addressed problem in patients with PD. The potential impact of OFF periods on sleep has not been well characterized.
About ONGENTYS ® (opicapone) Capsules ONGENTYS is a once-daily, oral, peripheral, selective and reversible catechol-O-methyltransferase (COMT) inhibitor approved by the U.S. Food and Drug Administration (FDA) as an add-on treatment to levodopa/carbidopa in patients with Parkinson's disease experiencing "OFF" episodes. ONGENTYS inhibits the COMT enzyme, which breaks down levodopa, making more levodopa available to reach the brain.
In June 2016 , BIAL – Portela & CA, S.A. (BIAL) received approval from the European Commission for ONGENTYS as an adjunct therapy to preparations of levodopa/DOPA decarboxylase inhibitors in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilized on those combinations. BIAL currently markets ONGENTYS in several European countries. Neurocrine Biosciences in-licensed opicapone from BIAL in 2017 and has exclusive development and commercialization rights in the U.S. and Canada .
Important Information
Approved Use ONGENTYS ® (opicapone) capsules is a prescription medicine used with levodopa and carbidopa in people with Parkinson's disease (PD) who are having "OFF" episodes.
It is not known if ONGENTYS is safe and effective in children.
Important Safety Information
Do not take ONGENTYS if you:
Before taking ONGENTYS, tell your healthcare provider about all of your medical conditions, including if you :
Tell your healthcare provider about all the medicines you take , including prescription and over-the-counter medicines, vitamins, and herbal supplements. Especially tell your healthcare provider if you take nonselective MAO inhibitors (such as phenelzine, tranylcypromine, and isocarboxazid) or catecholamine medicines (such as isoproterenol, epinephrine, norepinephrine, dopamine, and dobutamine), regardless of how you take the medicine (by mouth, inhaled, or by injection).
ONGENTYS and other medicines may affect each other causing side effects. ONGENTYS may affect the way other medicines work, and other medicines may affect how ONGENTYS works.
What should I avoid while taking ONGENTYS? Do not drive, operate machinery, or do other dangerous activities until you know how ONGENTYS affects you.
What are the possible side effects of ONGENTYS? ONGENTYS may cause serious side effects, including:
Tell your healthcare provider if you experience any of these side effects or notice changes in your behavior.
The most common side effects of ONGENTYS include uncontrolled sudden movements (dyskinesia), constipation, increase in an enzyme called blood creatine kinase, low blood pressure, and weight loss.
These are not all of the possible side effects of ONGENTYS. Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

About Parkinson's Disease Parkinson's disease is a chronic, progressive, and debilitating neurodegenerative disorder that affects approximately 1 million people in the U.S. and 6 million people worldwide. Parkinson's disease is associated with low dopamine levels produced in the brain. Dopamine helps transmit signals between the areas of the brain that control all purposeful movements, including talking, walking, and writing. As Parkinson's disease progresses, dopamine production steadily decreases, resulting in increased problems with motor symptoms including slowed movement (bradykinesia), tremor, rigidity, impaired posture and balance, and difficulty with speech and writing.
There is presently no cure for Parkinson's disease and management of the disease consists of the use of treatments that attempt to control motor symptoms primarily through dopaminergic mechanisms. The current gold standard for treatment of motor symptoms is levodopa/carbidopa. While levodopa/carbidopa improves patients' motor symptoms, as the disease progresses, the beneficial effects of levodopa begin to wear off more quickly. Patients then experience motor fluctuations throughout the day between "on" time, periods when the medication is working and Parkinson's disease symptoms are controlled, and "OFF" time, when the medication is not working and motor symptoms return.
