Ongentys® (opicapone) has been made available by Neurocrine Biosciences as an adjunctive treatment to levodopa/carbidopa in patients with Parkinson disease (PD) experiencing off episodes.

Opicapone is an oral, selective and reversible inhibitor of catechol-O-methyltransferase (COMT). By blocking the COMT enzyme, opicapone prevents the breakdown of levodopa, increasing its exposure and clinical effects in PD patients. The treatment is administered once daily at bedtime.

In April 2020, the Food and Drug Administration approved Ongentys based on data from 2 clinical trials, BIPARK-1 and BIPARK-2. Results from both studies showed that treatment with opicapone 50mg significantly reduced mean absolute off time and increased on time without troublesome dyskinesia compared with placebo.

With regard to safety, the most common adverse reactions reported with Ongentys include dyskinesia, constipation, increased blood creatine kinase, hypotension/syncope, and decreased weight. Other clinically significant adverse reactions may include cardiovascular effects with concomitant use of drugs metabolized by COMT, falling asleep during activities of daily living and somnolence, hallucinations and psychosis, impulse control/compulsive disorders, and withdrawal-emergent hyperpyrexia and confusion. The treatment is contraindicated with concomitant use of nonselective monoamine oxidase inhibitors and also in patients with pheochromocytoma, paraganglioma, or other catecholamine secreting neoplasms.
