SAN DIEGO, Sept. 15, 2022 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX) today will present data on the effects of ONGENTYS® (opicapone) capsules on soluble-catechol-O-methyltransferase (S-COMT) enzyme inhibition. These data (abstract #1025) are being shared at the MDS International Congress of Parkinson's Disease and Movement Disorders® September 15-18 in Madrid, Spain.
"These data demonstrate that COMT inhibition shown by opicapone leads to more consistent daily levodopa exposure, which continues to be a challenge and goal in treating Parkinson's disease," said Eiry W. Roberts, MD, Chief Medical Officer at Neurocrine Biosciences. "Adding a once-daily dose of opicapone 50 mg to levodopa/carbidopa resulted in inhibition of S-COMT activity and reduced fluctuations in L-dopa concentrations regardless of disease state, age, sex, ethnicity, or BMI."
The post-hoc analyses were conducted using data from 2 previous open-label Phase 1 studies of ONGENTYS, an approved once-daily adjunctive treatment to levodopa/carbidopa in patients with Parkinson's disease experiencing OFF time. Results of this post-hoc analysis showed that once-daily ONGENTYS 50 mg, when added to levodopa/carbidopa, decreased mean S-COMT activity by more than 80 percent in both patients with Parkinson's disease and healthy participants. Mean percentage reduction in S-COMT activity was 79–85 percent for all subgroups in both individual and pooled studies, although some subgroups had small participant numbers. ONGENTYS also reduced inter-patient variability in S-COMT activity by 86 percent from baseline.
Neurocrine Biosciences will also present survey results (abstract #993) on the continuing educational needs of U.S. clinicians managing OFF episodes in Parkinson's disease, demonstrating the variability in approach to managing OFF episodes and need for relevant Continuing Medical Education approaches.
A full list of abstracts being presented by Neurocrine Biosciences at MDS International Congress of Parkinson's Disease and Movement Disorders® is available on the meeting website.
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) in April 2020 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 (U.S.)
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.
