Catechol-O-Methyltransferase Inhibitor
Dosing in kidney impairment
Renal Impairment The renal route of elimination plays a minor role in the clearance of opicapone [see Clinical Pharmacology]. Avoid use of ONGENTYS in patients with end-stage renal disease (ESRD) (CLcr <15 mL/min). No dosage adjustment is required for patients with mild, moderate, or severe renal impairment. However, because of a potential for increased exposure, monitor patients with severe renal impairment for adverse reactions and discontinue ONGENTYS if tolerability issues arise. 8. 7 Hepatic Impairment Opicapone exposure is increased in patients with hepatic impairment [see Clinical Pharmacology] .
Avoid use of ONGENTYS in patients with severe (Child-Pugh C) hepatic impairment. Dosage adjustment is recommended for patients with moderate (Child-Pugh B) hepatic impairment [see Dosage and Administration] . No dosage adjustment is required in patients with mild (Child-Pugh A) hepatic impairment.
Dosing in liver impairment
Dosage Recommendations for Patients with Hepatic Impairment In patients with moderate hepatic impairment (Child-Pugh B), the recommended dose of ONGENTYS is 25 mg orally once daily at bedtime [see Use in Specific Populations, Clinical Pharmacology]. Avoid use of ONGENTYS in patients with severe (Child-Pugh C) hepatic impairment [ see Use in Specific Populations , Clinical Pharmacology ].
Preparation and administration
Dosing and Administration Information The recommended dosage of ONGENTYS is 50 mg administered orally once daily at bedtime. Patients should not eat food for 1 hour before and for at least 1 hour after intake of ONGENTYS [see Clinical Pharmacology].

7 DRUG INTERACTIONS
7.1 Non-Selective Monoamine Oxidase (MAO) Inhibitors Both ONGENTYS and non-selective MAO inhibitors (e.g., phenelzine, isocarboxazid, and tranylcypromine) inhibit catecholamine metabolism, leading to increased levels of catecholamines. Concomitant use may increase the risk of possible arrhythmias, increased heart rate, and excessive changes in blood pressure. Concomitant use of ONGENTYS with non-selective MAO inhibitors is contraindicated [see Contraindications ( 4 )] . Selective MAO-B inhibitors can be used concomitantly with ONGENTYS.
7.2 Effect of ONGENTYS on Other Drugs Drugs Metabolized by Catechol-O-Methyltransferase (COMT) Concomitant use of ONGENTYS with drugs metabolized by COMT may affect the pharmacokinetics of those drugs, which may increase the risk of possible arrhythmias, increased heart rate, and excessive changes in blood pressure [see Warnings and Precautions ( 5.1 )] . Drugs known to be metabolized by COMT should be administered with caution. Monitor for changes in heart rate, rhythm, and blood pressure in patients concomitantly treated with ONGENTYS and drugs metabolized by COMT [see Warnings and Precautions ( 5.1 )] .
Contraindications
4 CONTRAINDICATIONS ONGENTYS is contraindicated in patients with: Concomitant use of non-selective monoamine oxidase (MAO) inhibitors [ see Drug Interactions ( 7.1 ) ] . Pheochromocytoma, paraganglioma, or other catecholamine secreting neoplasms. Concomitant use of non-selective monoamine oxidase (MAO) inhibitors. ( 4 ) History of pheochromocytoma, paraganglioma, or other catecholamine secreting neoplasms. ( 4 )

Reported adverse events (FAERS)
Liver injury (LiverTox)
ELikelihood score E: Unlikely cause of clinically apparent liver injury.
Opicapone is a catechol-O-methyltransferase inhibitor that is used as adjunctive therapy to levodopa/carbidopa in patients with Parkinson disease experiencing difficulty with “off” episodes when motor symptoms breakthrough on treatment. Opicapone has been associated with a minimal rate of serum enzyme elevations during therapy and has not been linked to cases of clinically apparent liver injury with jaundice.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with use of ONGENTYS in pregnant women. In animal studies, oral administration of opicapone during pregnancy resulted in adverse effects on embryofetal development (increased incidence of fetal abnormalities) at clinically relevant plasma exposures in one of two species tested. In addition, opicapone is always given concomitantly with levodopa/carbidopa, which is known to cause developmental toxicity in rabbits ( s ee Data ). The background risk of major birth defects and miscarriage in the U.S. general population is 2-4% and 15-20% of clinically recognized pregnancies, respectively.
The background risk for major birth defects and miscarriage in patients with Parkinson’s disease is unknown. Data Animal Data Oral administration of opicapone (0, 150, 375, or 1000 mg/kg/day) to pregnant rats throughout gestation resulted in no adverse effects on embryofetal development. Plasma exposure (AUC) at the highest dose tested (1000 mg/kg/day) was approximately 40 times that in humans at the recommended human dose (50 mg/day).
In pregnant rabbits, oral administration of opicapone (0, 100, 175, or 225 mg/kg/day) during the period of organogenesis resulted in increased incidence of structural abnormalities at all doses tested; maternal toxicity was observed at all but the lowest dose tested. A no-effect dose for adverse effects on embryofetal development was not identified. Plasma exposure (AUC) at the low-effect dose (100 mg/kg/day) was less than that in humans at the RHD.
Oral administration of opicapone (0, 150, 375, or 1000 mg/kg/day) throughout gestation and lactation resulted in no adverse effects on pre- and postnatal development; however, effects on neurobehavioral development in the offspring were not rigorously assessed. Plasma exposure (AUC) at the highest dose tested (1000 mg/kg/day) was approximately 40 times that in humans at the RHD. Opicapone is always given concomitantly with levodopa/carbidopa, which is known to cause visceral and skeletal malformations in rabbits. The developmental toxicity of opicapone in combination with levodopa/carbidopa was not assessed in animals.
