⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
4.1. Therapeutic indications
Ongentys is indicated as adjunctive therapy to preparations of levodopa/ DOPA decarboxylase inhibitors (DDCI) in adult patients with Parkinson's disease and end-of-dose motor fluctuations who cannot be stabilised on those combinations.
4.2. Posology and method of administration
Posology
The recommended dose is 50 mg of opicapone.
Ongentys should be taken once-daily at bedtime at least one hour before or after levodopa combinations.
Dose adjustments of antiparkinsonian therapy
Ongentys is to be administered as an adjunct to levodopa treatment and enhances the effects of levodopa. Hence, it is often necessary to adjust levodopa dose by extending the dosing intervals and/or reducing the amount of levodopa per dose within the first days to first weeks after initiating the treatment with opicapone according to the clinical condition of the patient (see section 4.4).
Missed dose
If one dose is missed, the next dose should be taken as scheduled. The patient should not take an extra dose to make up for the missed dose.
Special populations
Elderly
No dose adjustment is needed for elderly patients (see section 5.2).
Caution must be exercised in patients ≥ 85 years of age as there is limited experience in this age group.
Renal impairment
No dose adjustment is necessary in patients with renal impairment, as opicapone is not excreted by the kidney (see section 5.2).
Hepatic impairment
No dose adjustment is necessary in patients with mild hepatic impairment (Child-Pugh Class A).
There is limited clinical experience in patients with moderate hepatic impairment (Child-Pugh Class B). Caution must be exercised in these patients and dose adjustment may be necessary (see section 5.2).
There is no clinical experience in patients with severe hepatic impairment (Child-Pugh Class C), therefore, opicapone is not recommended in these patients (see section 5.2).
Paediatric population
There is no relevant use of Ongentys in the paediatric population with Parkinson's disease and motor fluctuations.
Method of administration
Oral use.
The capsules should be swallowed whole with water.
4.3. Contraindications
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Phaeochromocytoma, paraganglioma, or other catecholamine secreting neoplasms.
History of neuroleptic malignant syndrome and/or non-traumatic rhabdomyolysis.
Concomitant use with monoamine oxidase (MAO-A and MAO-B) inhibitors (e.g. phenelzine, tranylcypromine and moclobemide) other than those for the treatment of Parkinson's disease (see section 4.5).
4.4. Special warnings and precautions for use
Dose adjustments of antiparkinsonian therapy
Ongentys is to be administered as an adjunct to levodopa treatment. Hence, the precautions valid for levodopa treatment should also be taken into account for Ongentys. Opicapone enhances the effects of levodopa. To reduce levodopa-related dopaminergic adverse reactions (e.g. dyskinesia, hallucinations, nausea, vomiting and orthostatic hypotension), it is often necessary to adjust the daily dose of levodopa by extending the dosing intervals and/or reducing the amount of levodopa per dose within the first days to first weeks after initiating treatment with Ongentys, according to the clinical condition of the patient (see section 4.2).
If Ongentys is discontinued it is necessary to adjust the dosing of the other antiparkinsonian treatments, especially levodopa, to achieve a sufficient level of control of the symptoms.
Psychiatric disorders
Patients and care-givers should be made aware that impulse control disorders including pathological gambling, increased libido, hypersexuality, compulsive spending or buying, binge eating and compulsive eating can occur in patients treated with dopamine agonists and/or other dopaminergic treatments. Patients should be monitored regularly for the development of impulse control disorders and review of treatment is recommended if such symptoms develop.
Others
Increases in liver enzymes were reported in studies with nitrocatechol inhibitors of catechol-Omethyltransferase (COMT). For patients who experience progressive anorexia, asthenia and weight decrease within a relatively short period of time, a general medical evaluation including liver function should be considered.
Excipients
Ongentys contains lactose. Patients with rare hereditary problems of galactose intolerance, the total lactase deficiency or glucose-galactose malabsorption should not take this medicinal product.
Ongentys contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially 'sodium-free'.
4.5. Interaction with other medicinal products and other forms of interaction
Monoamino oxidase (MAO) inhibitors
Combination of opicapone and MAO inhibitors could result in inhibition of the majority of the pathways responsible for the metabolism of catecholamines. Because of this, concomitant use of opicapone with MAO inhibitors (e.g. phenelzine, tranylcypromine and moclobemide) other than those for the treatment of Parkinson's disease is contraindicated (see section 4.3).
Concomitant use of opicapone and MAO inhibitors for the treatment of Parkinson's disease, e.g. rasagiline (up to 1 mg/day) and selegiline (up to 10 mg/day in oral formulation or 1.25 mg/day in buccal absorption formulation), is permissible.
There is no experience with opicapone when used concomitantly with the MAO-B inhibitor safinamide. Therefore, their concomitant use should be considered with appropriate caution.
Medicinal products metabolised by COMT
Opicapone may interfere with the metabolism of medicinal products containing a catechol group that are metabolised by COMT, e.g. rimiterole, isoprenaline, adrenaline, noradrenaline, dopamine, dopexamine or dobutamine, leading to potentiated effects of these medicinal products. Careful monitoring of patients being treated with these medicinal products is advised when opicapone is used.
Tricyclic antidepressants and noradrenaline re-uptake inhibitors
There is limited experience with opicapone when used concomitantly with tricyclic antidepressants and noradrenaline re-uptake inhibitors (e.g. venlafaxine, maprotiline and desipramine). Thus, their concomitant use should be considered with appropriate caution.
Quinidine
A study conducted in healthy volunteers showed that when a single dose of 50 mg opicapone was coadministered (within 1 hour) with a single dose of quinidine (600 mg), systemic exposure of opicapone decreased by 37% (AUC0-tlast). Thus, particular consideration should be given to cases where quinidine needs to be administered together with opicapone as their co-administration should be avoided.
CYP2C8 and OATP1B1 substrates
Opicapone is a weak in vitro inhibitor of CYP2C8 and OATP1B1, whereas repaglinide is a sensitive CYP2C8 and OATP1B1 substrate. A study conducted in healthy subjects showed that there were no changes in repaglinide's exposure when repaglinide was administered following multiple once-daily administration of opicapone 50 mg.
4.6. Fertility, pregnancy and lactation
Pregnancy
There are no or limited amount of data from the use of opicapone in pregnant women. Opicapone crossed the placenta in rats. Animal studies are insufficient with respect to reproductive toxicity (see section 5.3). Ongentys is not recommended during pregnancy and in women of childbearing potential not using contraception.
Breast-feeding
Opicapone levels in the milk of lactating rats were equivalent to those in plasma. It is unknown whether opicapone or its metabolites are excreted into human milk. A risk to the newborns/infants cannot be excluded. Breast-feeding should be discontinued during treatment with Ongentys.
Fertility
The effects of opicapone on fertility in humans have not been studied. Animal studies with opicapone do not indicate harmful effects with respect to fertility (see section 5.3).
4.7. Effects on ability to drive and use machines
Opicapone in association with levodopa may have major influence on the ability to drive and use machines. Opicapone may, together with levodopa, cause dizziness, symptomatic orthostatism and somnolence. Therefore, caution should be exercised when driving or using machines.
4.8. Undesirable effects
Summary of the safety profile
The most common adverse reactions reported were nervous system disorders. Dyskinesia was the most frequently reported treatment-emergent adverse reaction (17.7%).
