This information is intended for use by health professionals
This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions. See section 4.8 for how to report adverse reactions.
PosologyThe recommended dose of opicapone is 50 mg.Ongentys should be taken once-daily at bedtime at least one hour before or after levodopa combinations.
Dose adjustments of antiparkinsonian therapyOpicapone enhances the effects of levodopa. Hence, it is often necessary to adjust levodopa dosage within the first days to first weeks after initiating the treatment with opicapone (see section 4.4).
Missed doseIf 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.
ElderlyNo 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 impairmentNo dose adjustment is necessary in patients with renal impairment, as opicapone is not excreted by the kidney (see section 5.2).
Hepatic impairmentNo 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, Ongentys is not recommended in these patients (see section 5.2).
Paediatric populationThere is no relevant use of Ongentys in the paediatric population with Parkinson's disease and motor fluctuations.
Method of administrationOral use.The capsules should be swallowed whole with water.
Dose adjustments of antiparkinsonian therapyOngentys 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 disordersPatients 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.
OthersIncreases in liver enzymes were reported in studies with nitrocatechol inhibitors of catechol-O- methyltransferase (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.
Intolerance to excipientsOngentys contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take Ongentys.
Monoamino oxidase (MAO) inhibitorsCombination 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.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 (see section 4.3).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 COMTOpicapone 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 inhibitorsThere 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.
RepaglinideOpicapone is a weak inhibitor of CYP2C8. A study in healthy subjects using a dose of 25 mg, and a less than optimal formulation, showed an average increase of 30 % in the rate, but not the extent, of exposure to repaglinide when co-administered (i.e. given at the same time) with opicapone most likely caused by an inhibition of CYP2C8. Thus, particular consideration should be given to medicinal products metabolised by CYP2C8 and their co-administration must be avoided.
OATP1B1 substratesOpicapone is a weak inhibitor of OATP1B1. There is no experience with opicapone when used concomitantly with OATP1B1 substrates. Thus, particular consideration should be given to medicinal products transported by OATP1B1 and their concomitant use should be considered with appropriate caution.
PregnancyThere are no or limited amount of data from the use of opicapone in pregnant women. 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-feedingIt is unknown whether opicapone or its metabolites are excreted in human milk. A risk to the newborns/infants cannot be excluded. Breast-feeding should be discontinued during treatment with Ongentys.
FertilityThe 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).

Mechanism of actionOpicapone is a peripheral, selective and reversible catechol-O-methyltransferase (COMT) inhibitor endowed with a high binding affinity (sub-picomolar) that translates into a slow complex dissociation rate constant and a long duration of action (>24 hours) in vivo.In the presence of a DOPA decarboxylase inhibitor (DDCI), COMT becomes the major metabolising enzyme for levodopa, catalysing its conversion to 3-O-methyldopa (3-OMD) in the brain and periphery. In patients taking levodopa and a peripheral DDCI, such as carbidopa or benserazide, opicapone increases levodopa plasma levels thereby improving the clinical response to levodopa.
Pharmacodynamic effectsOpicapone showed a marked (>90%) and long-lasting (>24 hours) COMT inhibition in healthy subjects after administration of 50 mg opicapone.At steady state, opicapone 50 mg significantly increased the extent of levodopa systemic exposure approximately 2 fold compared to placebo following a single oral administration of either 100/25 mg levodopa/carbidopa or 100/25 mg levodopa/benserazide administered 12 h after the opicapone dose.
Clinical efficacy and safetyThe efficacy and safety of opicapone has been demonstrated in two Phase 3 double-blind, placebo and active (Study 1 only) controlled studies in 1,027 randomized adult patients with Parkinson's disease treated with levodopa/DDCI (alone or in combination with other antiparkinsonian drugs) and end-of- dose motor fluctuations for up to 15 weeks. At screening, the mean age was similar in all treatment groups in both studies, ranging between 61.5 and 65.3 years. Patients had disease severity stages 1 to 3 (modified Hoehn and Yahr) at ON, were treated with 3 to 8 daily doses of levodopa/DDCI and had a daily average OFF-time of at least 1.5 hours. In both studies, 783 patients were treated with 25 mg or 50 mg of opicapone or placebo. In Study 1, 122 patients were treated with opicapone 5 mg and 122 patients were treated with entacapone 200 mg (active comparator). The majority of patients treated in both pivotal studies were treated with immediate-release levodopa/DDCI. There were 60 patients in the combined Phase 3 studies who were predominantly using controlled-release levodopa (i.e. >50% of their levodopa/DDCI formulations), 48 of whom were treated solely with controlled-release formulations of levodopa. Although there is no evidence that either the efficacy or safety of opicapone would be affected by use of controlled-release levodopa preparations, the experience with such preparations is limited.Opicapone demonstrated clinical efficacy superior to placebo during the double-blind treatment, both for the primary efficacy variable used in both pivotal studies, i.e. reduction in OFF-time (Table 2), the proportion of OFF-time responders (i.e. a subject who had a reduction in OFF-time of at least 1 hour from baseline to endpoint) (Table 3) and for most diary derived secondary endpoints.The LS mean reduction in absolute OFF-time from baseline to endpoint in the entacapone group was -78.7 minutes. The difference in LS mean change in OFF-time of entacapone to placebo in Study 1 was -30.5 minutes. The difference in LS mean change in OFF-time of opicapone 50 mg to entacapone was -24.8 minutes and non-inferiority of opicapone 50 mg to entacapone was demonstrated (95% confidence interval: -61.4, 11.8).

Note: A responder was a patient who had a reduction of at least 1 hour in absolute OFF-time (OFF-time responder)The results of the open-label (OL) extension studies of 1 year duration in 862 patients who continued treatment from the double-blind studies (Study 1-OL and Study 2-OL) indicated maintenance of the effect achieved during DB study periods. In the OL studies, all patients began at a dose of 25 mg opicapone for the first week (7 days), regardless of their prior treatment in the double-blind period. If end-of-dose motor fluctuations were not sufficiently controlled and tolerability allowed, the opicapone dose could be increased to 50 mg. If unacceptable dopaminergic adverse events were seen, the levodopa dose was to be adjusted. If not sufficient to manage the adverse events, the opicapone dose could then be down titrated. For other adverse events, the levodopa and/or opicapone dose could be adjusted.
Paediatric populationThe European Medicines Agency has waived the obligation to submit the results of studies with opicapone in all subsets of the paediatric population with Parkinson's disease and motor fluctuations (see section 4.2 for information on paediatric use).
AbsorptionOpicapone presents a low absorption (~20%). Pharmacokinetic results showed that opicapone is rapidly absorbed, with a tmax of 1.0 h to 2.5 h following once-daily multiple-dose administration up to 50 mg opicapone.
DistributionIn vitro studies over the opicapone concentration range 0.3 to 30 mcg/mL showed that binding of 14C-opicapone to human plasma proteins is high (99.9%) and concentration-independent. The binding of 14C-opicapone to plasma proteins was unaffected by the presence of warfarin, diazepam, digoxin and tolbutamide, and the binding of 14C-warfarin, 2-14C-diazepam, 3H-digoxin and 14C-tolbutamide was unaffected by the presence of opicapone and opicapone sulphate, the major human metabolite.After oral administration, the apparent volume of distribution of opicapone at a dose of 50 mg was 29 L with an inter-subject variability of 36%.
BiotransformationSulphation of opicapone appears to be the major metabolic pathway in humans, yielding the inactive opicapone sulphate metabolite. Other metabolic pathways include glucuronidation, methylation and reduction.The most abundant peaks in plasma after a single-dose of 100 mg 14C-opicapone are metabolites BIA 9-1103 (sulphate) and BIA 9-1104 (methylated), 67.1 and 20.5% of radioactive AUC respectively. Other metabolites were not found in quantifiable concentrations in the majority of plasma samples collected during a clinical mass balance study..The reduced metabolite of opicapone (found to be active in non-clinical studies) is a minor metabolite in human plasma, and represented less than 10% of total systemic exposure to opicapone.In in vitro studies in human hepatic microsomes, minor inhibition of CYP1A2 and CYP2B6 was observed. All reductions in activity essentially occurred at the highest concentration of opicapone (10 mcg/mL).Opicapone inhibited CYP2C8 activity with an estimated Ki of 0.9 mcg/mL. A study in healthy subjects showed an average increase of 30% in the rate, but not extent, of exposure to repaglinide, a CYP2C8 substrate (see section 4.5).Opicapone reduced CYP2C9 activity through competitive / mixed type mode of inhibition. However, clinical interaction studies conducted with warfarin showed no effect of opicapone on the pharmacodynamics of warfarin, a substrate of CYP2C9.
EliminationIn healthy subjects, the opicapone elimination half-life (t1/2) was 0.7 h to 3.2 h following once-daily multiple-dose administration up to 50 mg opicapone.Following once-daily multiple oral doses of opicapone in the dose range of 5 to 50 mg, opicapone sulphate presented a long terminal phase with elimination half-life values ranging from 94 h to 122 h and, as a consequence of this long terminal elimination half-life, opicapone sulphate presented a high accumulation ratio in plasma, with values close of up to 6.6.After oral administration, the apparent total body clearance of opicapone at a dose of 50 mg was 22 L/h, with an inter-subject variability of 45%.Following administration of a single oral dose of 14C-opicapone, the main excretion route of opicapone and its metabolites was faeces, accounting for 58.5% to 76.8% of the administered radioactivity (mean 67.2%). The remainder of the radioactivity was excreted in urine (mean 12.8%) and via expired air (mean 15.9%). In urine, the primary metabolite was the glucuronide metabolite of opicapone, while parent drug and other metabolites were generally below the limit of quantification. Overall, it can be concluded that the kidney is not the primary route of excretion. Therefore, it can be presumed that opicapone and its metabolites are mainly excreted in the faeces.
Linearity/non-linearityOpicapone exposure increased in a dose proportional manner following once-daily multiple dose administration up to 50 mg opicapone.
TransportersIn vitro studies have shown that opicapone is not transported by OATP1B1, but is transported by OATP1B3, and efflux transported by P-gp and BCRP. BIA 9-1103, its major metabolite, was transported by OATP1B1 and OATP1B3, and efflux transported by BCRP, but is not a substrate for the P-gp/MDR1 efflux transporter.Considering the plasma free fractions of opicapone and BIA 9-1103 detected in clinical studies, no interaction is expected in OAT1, OAT3, OATP1B1, OATP1B3, OCT1, OCT2, BCRP, P-gp/MDR1, BSEP, MATE1 and MATE2-K transporters. Inhibition of OATP1B1 cannot be ruled out and this has not been studied.
Elderly (≥ 65 years old)The pharmacokinetics of opicapone was evaluated in elderly subjects (aged 65-78 years old) after 7- day multiple-dose administration of 30 mg. An increase in both the rate and extent of systemic exposure was observed for the elderly population when compared to the young population. The S- COMT activity inhibition was significantly increased in elderly subjects. The magnitude of this effect is not considered to be of clinical relevance.
WeightThere is no relationship between exposure of opicapone and body weight over the range of 40-100 kg.Hepatic impairmentThere is limited clinical experience in patients with moderate hepatic impairment (Child-Pugh Class B). The pharmacokinetics of opicapone was evaluated in healthy subjects and moderate chronic hepatic impaired patients after administration of a single-dose of 50 mg. The bioavailability of opicapone was significantly higher in patients with moderate chronic hepatic impairment and no safety concerns were observed. However, as opicapone is to be used as adjunctive levodopa-therapy, dose adjustments may be considered based on a potentially enhanced levodopa dopaminergic response and associated tolerability. There is no clinical experience in patients with severe hepatic impairment (Child-Pugh Class C) (see section 4.2).
Renal impairmentThe pharmacokinetics of opicapone was not directly evaluated in subjects with chronic renal impairment. However, an evaluation with 50 mg opicapone was performed in subjects included in both phase 3 studies with GFR/1.73 m2 <60 mL/min (i.e. moderately decreased renal elimination capacity), and using pooled BIA 9-1103 data (major metabolite of opicapone). BIA 9-1103 plasma levels were not affected in patients with chronic renal impairment, and as such, no dose adjustment needs to be considered.
