Ropilynz

Ropilynz XL 2 mg prolonged-release tablets

Each prolonged release tablet contains 2 mg ropinirole (as ropinirole hydrochloride).

Excipients with known effect:

Each 2 mg prolonged-release tablet contains 1.8 mg of lactose monohydrate.

For the full list of excipients, see section 6.1.

Prolonged-release tablet.

Pink, round biconvex tablets 6.8 ± 0.1 mm in diameter and 5.5 ± 0.2 mm in thickness.

Treatment of Parkinson's disease under the following conditions:

• Initial treatment as monotherapy, in order to delay the introduction of levodopa

• In combination with levodopa, over the course of the disease, when the effect of levodopa wears off or becomes inconsistent and fluctuations in the therapeutic effect occur (“end of dose” or “on-off” type fluctuations).

Posology

Adults

Individual dose titration against efficacy and tolerability is recommended.

Initial titration

The starting dose of ropinirole prolonged-release tablets is 2 mg once daily for the first week; this should be increased to 4 mg once daily from the second week of treatment. A therapeutic response may be seen at a dose of 4 mg once daily of ropinirole prolonged-release tablets.

Patients who initiate treatment with a dose of 2 mg/day of ropinirole prolonged-release tablets and who experience undesirable effects that they cannot tolerate, may benefit from switching to treatment with ropinirole immediate-release tablets at a lower daily dose, divided into three equal doses.

Therapeutic regimen

Patients should be maintained on the lowest dose of ropinirole prolonged-release tablets that achieves symptomatic control.

If sufficient symptomatic control is not achieved or maintained at a dose of 4 mg once daily of ropinirole prolonged-release tablets, the daily dose may be increased by 2 mg at weekly or longer intervals up to a dose of 8 mg once daily of ropinirole prolonged-release tablets.

If sufficient symptomatic control is still not achieved or maintained at a dose of 8 mg once daily of ropinirole prolonged-release tablets, the daily dose may be increased by 2 mg to 4 mg at two weekly or longer intervals. The maximum daily dose of ropinirole prolonged-release tablets is 24 mg.

It is recommended that patients are prescribed the minimum number of ropinirole prolonged- release tablets that are necessary to achieve the required dose by utilising the highest available strengths of ropinirole prolonged-release tablets.

When Ropilynz XL prolonged-release tablets are administered as adjunct therapy to levodopa, it may be possible to reduce gradually the levodopa dose, depending on the clinical response. In clinical trials, the levodopa dose was reduced gradually by approximately 30% in patients receiving ropinirole prolonged-release tablets concurrently. In patients with advanced Parkinson's disease, receiving Ropilynz XL prolonged-release tablets in combination with levodopa, dyskinesias can occur during the initial titration of Ropilynz XL prolonged-release tablets. In clinical trials it was shown that a reduction of the levodopa dose may ameliorate dyskinesia (see section 4.8).

When switching treatment from another dopamine agonist to ropinirole, the marketing authorisation holder's guidance on discontinuation should be followed before initiating ropinirole.

As with other dopamine agonists, it is necessary to discontinue ropinirole treatment gradually by reducing the daily dose over the period of one week (see section 4.4).

Switching from ropinirole film-coated (immediate release) tablets to Ropilynz XL prolonged- release tablets

Patients may be switched overnight from ropinirole film-coated (immediate-release) tablets to ropinirole prolonged-release tablets. The dose of ropinirole prolonged-release tablets should be based on the total daily dose of ropinirole film-coated (immediate- release) tablets that the patient was taking. The table below shows the recommended dose of Ropilynz XL prolonged- release tablets for patients switching from ropinirole film-coated (immediate-release) tablets. If patients are taking a different total daily dose of ropinirole film-coated (immediate-release) tablets to those typically prescribed doses as shown in the table, they should be switched to the nearest available dose of ropinirole prolonged-release tablets as stated in the table.

After switching to Ropilynz XL prolonged-release tablets, the dose may be adjusted depending on the therapeutic response (see “Initial titration” and “Therapeutic regimen” above).

Dose interruption or discontinuation

If treatment is interrupted for one day or more, re-initiation by dose titration on ropinirole immediate-release tablets should be considered.

If it is necessary to discontinue ropinirole treatment, this should be done gradually by reducing the daily dose over the period of one week.

Paediatric population

Ropilynz XL prolonged-release tablets are not recommended for use in children below 18 years of age due to a lack of data on safety and efficacy.

Elderly

The clearance of ropinirole is decreased by approximately 15% in patients 65 years of age or above. Although a dose adjustment is not required, ropinirole dose should be individually titrated, with careful monitoring of tolerability, to the optimal clinical response. In patients aged 75 years and above, slower titration during treatment initiation may be considered. Renal impairment

In parkinsonian patients with mild to moderate renal impairment (creatinine clearance between 30 and 50 ml/min) no change in the clearance of ropinirole was observed, indicating that no dosage adjustment is necessary in this population.

A study into the use of ropinirole in patients with end stage renal disease (patients on haemodialysis) has shown that a dose adjustment in these patients is required as follows: the recommended initial dose of Ropilynz XL is 2 mg once daily. Further dose escalations should be based on tolerability and efficacy. The recommended maximum dose of Ropilynz XL is 18 mg/day in patients receiving regular haemodialysis.

Supplemental doses after haemodialysis are not required (see section 5.2).

The use of ropinirole in patients with severe renal impairment (creatinine clearance less than 30 ml/min) without regular haemodialysis has not been studied.

Hepatic impairment

The use of ropinirole in patients with hepatic impairment has not been studied. Administration of ropinirole to such patients is not recommended.

Method of administration

For oral use

Ropilynz XL prolonged-release tablets should be taken once a day, at a similar time each day. The prolonged-release tablets may be taken with or without food (see section 5.2).

Ropilynz XL prolonged-release tablets must be swallowed whole and must not be chewed, crushed or divided. The tablets may be taken with or without food. A high fat meal may double the AUC and Cmax in some individuals (see section 5.2).

- Hypersensitivity to the active substance or to any of the excipients, listed in section 6.1.

- Severe renal impairment (creatinine clearance < 30 ml/min) without regular haemodialysis.

- Hepatic impairment.

Ropinirole has been associated with somnolence and episodes of sudden sleep onset, particularly in patients with Parkinson's disease. Sudden onset of sleep during daily activities, in some cases without awareness or warning signs, has been reported (see section 4.8). Patients must be informed of this and advised to exercise caution while driving or operating machines during treatment with ropinirole. Patients who have experienced somnolence and/or an episode of sudden sleep onset must refrain from driving or operating machines. A reduction of dosage or termination of therapy may be considered.

Due to the risk of hypotension, blood pressure monitoring is recommended, particularly at the start of treatment, in patients with severe cardiovascular disease (in particular coronary insufficiency).

Patients with major psychiatric or psychotic disorders, or a history of these disorders, should not be treated with dopamine agonists unless the potential benefits outweigh the risks (see also section 4.5).

Ropilynz XL tablets are designed to release the active substance over a 24hr period. If rapid gastrointestinal transit occurs, there may be risk of incomplete release of the active substance and of the active substance residue being passed in the stool.

Impulse control disorders

Patients should be regularly monitored for the development of impulse control disorders. Patients and carers should be made aware that behavioural symptoms of 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, including ropinirole. Dose reduction/tapered discontinuation should be considered if such symptoms develop. Impulse control disorders were reported especially at high doses and were generally reversible upon reduction of the dose or treatment discontinuation. Risk factors such as a history of compulsive behaviours were present in some cases (see section 4.8).

Neuroleptic malignant syndrome

Symptoms suggestive of neuroleptic malignant syndrome have been reported with abrupt withdrawal of dopaminergic therapy. Therefore, it is recommended to taper treatment. (see section 4.2).

Dopamine agonist withdrawal syndrome

To discontinue treatment in patients with Parkinson's disease, ropinirole should be tapered off (see section 4.2). Non-motor adverse effects may occur when tapering or discontinuing dopamine agonists including ropinirole. Symptoms include apathy, anxiety, depression, fatigue, sweating and pain which may be severe. Patients should be informed about this before tapering the dopamine agonist, and monitored regularly thereafter. In case of persistent symptoms, it may be necessary to increase the ropinirole dose temporarily (see section 4.8).

Hallucinations:

Hallucinations are known as an adverse reaction of treatment with dopamine agonists and levodopa.

Patients should be informed that hallucinations can occur.

Excipients:

Ropilynz XL 2mg

Ropilynz XL contains lactose. Patients with rare hereditary problems of galactose intolerance, the total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

This medicinal product contains less than 1 mmol sodium (23 mg) per prolonged-release tablet, that is to say essentially 'sodium-free'.

There is no pharmacokinetic interaction between ropinirole and L-dopa or domperidone which would necessitate dosage adjustment of these medicinal products.

Neuroleptics and other centrally active dopamine antagonists, such as sulpiride or metoclopramide, may diminish the effectiveness of ropinirole and therefore, concomitant use of these medicinal products should be avoided.

Increased plasma concentrations of ropinirole have been observed in patients treated with high doses of oestrogens. In patients already receiving hormone replacement therapy (HRT), ropinirole treatment may be initiated in the normal manner. However, it may be necessary to adjust the ropinirole dose, in accordance with clinical response, if HRT is stopped or introduced during treatment with ropinirole.

Ropinirole is principally metabolised by the cytochrome P450 enzyme CYP1A2. A pharmacokinetic study (with a ropinirole film-coated (immediate-release) tablet dose of 2 mg, three times a day) in Parkinson's disease patients, revealed that ciprofloxacin increased the Cmax and AUC of ropinirole by 60% and 84% respectively, with a potential risk of adverse events. Hence, in patients already receiving ropinirole, the dose of ropinirole may need to be adjusted when medicinal products known to inhibit CYP1A2, e.g. ciprofloxacin, enoxacin, cimetidin or fluvoxamine, are introduced or withdrawn.

A pharmacokinetic interaction study in patients with Parkinson's disease between ropinirole (with a ropinirole film-coated (immediate-release) tablet dose of 2 mg, three times a day) and theophylline, a substrate of CYP1A2, revealed no change in the pharmacokinetics of either ropinirole or theophylline.

Smoking is known to induce CYP1A2 metabolism, therefore if patients stop or start smoking during treatment with ropinirole, adjustment of dose may be required.

Pregnancy

There are no adequate data from the use of ropinirole in pregnant women.

Studies in animals have shown reproductive toxicity (see section 5.3). As the potential risk for humans is unknown, it is recommended that ropinirole is not used during pregnancy unless the potential benefit to the patient outweighs the potential risk to the foetus.

Breastfeeding

Ropinirole-related material was shown to transfer into the milk of lactating rats. It is unknown whether ropinirole and its metabolites are excreted in human milk. A risk to the suckling child cannot be excluded.

Ropinirole should not be used in breast feeding mothers as it may inhibit lactation.

Fertility

There are no data on the effects of ropinirole on human fertility. In female fertility studies in rats, effects were seen on implantation but no effects were seen on male fertility (see section 5.3)

Ropinirole may have a major effect on the ability to drive and use machines.

Patients being treated with ropinirole and presenting with somnolence and/or sudden sleep episodes must be informed to refrain from driving or engaging in activities where impaired alertness may put themselves or others at risk of serious injury or death (e.g. using machines) until such recurrent episodes and somnolence have resolved (see section 4.4).

Adverse events are listed below by system organ class and frequency.

Frequencies are defined as: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be estimated from the available data).

During clinical trials, the most commonly reported undesirable effects for ropinirole prolonged-release tablets were somnolence and nausea during monotherapy and dyskinesia during adjunctive therapy with levodopa.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme (www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store).

The symptoms of ropinirole overdose are related to its dopaminergic activity. These symptoms may be alleviated by appropriate treatment with dopamine antagonists such as neuroleptics or metoclopramide.

Pharmacotherapeutic group: Dopamine agonists, ATC code N04BC04

Mechanism of action

Parkinson's disease is characterised by a marked dopamine deficiency in the nigral striatal system. Ropinirole is a non-ergoline D2/D3 dopamine agonist that alleviates this deficiency which stimulates striatal dopamine receptors.

Ropinirole acts in the hypothalamus and pituitary to inhibit the secretion of prolactin.

Clinical efficacy

A 36-week, double-blind, three-period crossover study, in monotherapy with a primary end point of change from period baseline in Unified Parkinson's Disease Rating Scale (UPDRS) total motor score was conducted in 161 patients with early phase Parkinson's disease. A subgroup analysis of patients initiated on monotherapy treatment with ropinirole immediate release tablets and switched overnight to the nearest equivalent dose of ropinirole prolonged release tablets was consistent with similar efficacy from equivalent mg for mg doses. The adjusted mean difference between ropinirole prolonged-release tablets and immediate-release film-coated tablets at study endpoint was 0.7 points (95% CI: [-1.51,0.10], p=0.0842).

Following the overnight switch to a similar dose of the alternative tablet formulation, there was no difference in the adverse event profile and less than 3% of patients required a dose adjustment (all dose adjustments were increases by one dose level. No patients required a dose decrease).

A 24-week, double-blind, placebo-controlled, parallel group study of ropinirole prolonged- release tablets in patients with Parkinson's disease who were not optimally controlled on levodopa demonstrated that adjunctive therapy of ropinirole prolonged-release tablets results in clinically relevant and statistically significant superiority over placebo in a change from baseline in awake time “off” (adjusted mean treatment difference -1.7 hours, [95% CI: [-2.34, -1.09], p<0.0001). This was supported by secondary efficacy parameters of change from baseline in total awake time “on” (+1.7 hours (95% CI: [1.06, 2.33], p<0.0001) and total awake time “on” without troublesome dyskinesias (+1.5 hours (95% CI: [0.85, 2.13], p<0.0001). Importantly, there was no indication of an increase from baseline in awake time “on” with troublesome dyskinesias, either from diary card data or from the UPDRS items.

Study of the effect of ropinirole on cardiac repolarisation

A thorough QT study conducted in male and female healthy volunteers who received doses of 0.5, 1, 2 and 4 mg of ropinirole immediate-release tablets once daily showed a maximum increase of the QT interval duration at the 1 mg dose of 3.46 milliseconds (point estimate) as compared to placebo. The upper bound of the one sided 95% confidence interval for the largest mean effect was less than 7.5 milliseconds. The effect of ropinirole at higher doses has not been systematically evaluated.

The available clinical data from a thorough QT study do not indicate a risk of QT prolongation at doses of ropinirole up to 4 mg/day. A risk of QT prolongation cannot be excluded as a thorough QT study at doses up to 24 mg/day has not been conducted.

Absorption

Bioavailability of ropinirole is approximately 50% (36–57%). Following oral administration, of ropinirole prolonged-release tablets plasma concentrations increase slowly, with a median time to Cmax generally achieved between 6 and 10 hours.

In a steady-state study in Parkinson's disease patients receiving 12 mg of ropinirole prolonged release tablets once daily, a high fat meal increased the systemic exposure to ropinirole as shown by an average 20% increase in AUC (90% CI: [1.12, 1.28]) and an average 44% increase in Cmax (90% CI: [1.34, 1.56]). Tmax was delayed by 3.0 hours. However, in the studies that established the safety and efficacy of ropinirole prolonged release tablets, patients were instructed to take study medicinal product without regard to food intake.

The systemic exposure to ropinirole is comparable for ropinirole prolonged-release tablets and ropinirole film-coated (immediate-release) tablets based on the same daily dose.

Distribution

Plasma protein binding of the drug is low (10–40%). Consistent with its high lipophilicity, ropinirole exhibits a large volume of distribution (approximately 7 L/kg).

Biotransformation

Ropinirole is primarily cleared by CYP1A2 metabolism and its metabolites are mainly excreted in the urine. The major metabolite is at least 100-times less potent than ropinirole in animal models of dopaminergic function.

Elimination

Ropinirole is cleared from the systemic circulation with an average elimination half-life of about six hours. The increase in systemic exposure (Cmax and AUC) to ropinirole is approximately proportional over the therapeutic dose range. No change in the oral clearance of ropinirole is observed following single and repeated oral administration. Wide inter-individual variability in the pharmacokinetic parameters has been observed. Following steady-state administration of ropinirole prolonged-release tablets, the inter-individual variability for Cmax was between 30% and 55% and for AUC was between 40% and 70%.

Special populations

Renal Impairment

There was no changed observed in the pharmacokinetics of ropinirole in Parkinson's disease patients with mild to moderate renal impairment.

In patients with end stage renal disease receiving regular haemodialysis, oral clearance of ropinirole is reduced by approximately 30%. Oral clearance of the metabolites SKF-104557 and SKF-89124 were also reduced by approximately 80% and 60%, respectively. Therefore, the recommended maximum dose is limited to 18 mg/day in these patients with Parkinson's disease (see section 4.2).

Reproductive toxicity

In fertility studies in female rats, effects were seen on implantation due to the prolactin-lowering effect of ropinirole. It should be noted that prolactin is not essential for implantation in humans.

Administration of ropinirole to pregnant rats at maternally toxic doses resulted in decreased foetal body weight at 60 mg/kg/day (approximately twice the highest AUC at the Maximum Recommended Human Dose (MRHD)), increased foetal death at 90 mg/kg/day (mean AUC in rats is approximately 3 times the highest AUC at the MRHD) and digit malformations at 150 mg/kg/day (approximately 5 times the highest AUC at the MRHD). There were no teratogenic effects in the rat at 120 mg/kg/day (approximately 4 times the highest AUC at the MRHD) and no indication of an effect during organogenesis in the rabbit when given alone at 20 mg/kg (9.5 times the mean human Cmax at the MRHD).

However, ropinirole at 10 mg/kg (4.8 times the mean human Cmax at the MRHD) administered to rabbits in combination with oral L-dopa produced a higher incidence and severity of digit malformations than L-dopa alone.

Toxicology

The toxicology profile is principally determined by the pharmacological activity of ropinirole: behavioural changes, hypoprolactinaemia, decrease in blood pressure and heart rate, ptosis and salivation. In the albino rat only, retinal degeneration was observed in a long-term study at the highest dose (50 mg/kg/day) and was probably associated with an increased exposure to light.

Genotoxicity

Genotoxicity was not observed in a battery of in vitro and in vivo tests.

Carcinogenicity

From two-year studies conducted in the mouse and rat at doses up to 50 mg/kg there was no evidence of any carcinogenic effect in the mouse. In the rat, the only ropinirole-related lesions were Leydig cell hyperplasia and testicular adenoma resulting from the hypoprolactinaemic effect of ropinirole. These lesions are considered to be a species specific phenomenon and do not constitute a hazard with regard to the clinical use of ropinirole.

Safety pharmacology

In vitro studies have shown that ropinirole inhibits hERG-mediated currents. The IC50 is 5fold higher than the expected maximum plasma concentration in patients treated at the highest recommended dose (24 mg/day), see section 5.1.
