Patient’s Name: Date treatment commenced: AREAS OF RESPONSIBILITY FOR THE SHARING OF CARE This shared care agreement outlines suggested ways in which the responsibilities for managing the prescribing of apomorphine for adults can be shared between the specialist and general practitioner (GP). GPs are invited to participate. If the GP is not confident to undertake these roles, then he or she is under no obligation to do so. In that case, the total clinical responsibility for the patient for the diagnosed condition remains with the specialist. If a specialist asks the GP to prescribe this drug, the GP should reply to this request as soon as practicable. Sharing of care assumes communication between the specialist, GP and patient. The intention to share care should be explained to the patient by the doctor initiating treatment. It is important that patients are consulted about treatment and are in agreement with it. Patients are under regular follow-up, which provides opportunities to discuss drug therapy. The doctor who prescribes the medication legally assumes clinical responsibility for the drug and the consequences of its use. RESPONSIBILITIES and ROLES Specialist responsibilities Diagnosis of Parkinson’s disease and initiation of apomorphine treatment. This would include developing a treatment strategy via pen or by subcutaneous infusion. 2. Discuss the benefits and side effects of treatment with the patient carers and community team. 3. Dose stabilisation: initial dosage adjustment until stable. Thereafter, during maintenance treatment, advice to the GP on any further dose adjustments required. 4. Ask the GP whether he or she is willing to participate in shared care, and agree with the GP as to who will discuss the shared care arrangement with the patient. 5. Monitor regular blood count. These will be checked regularly at outpatient visits. 6. Communicate promptly with the GP when treatment is changed. 7. Have a mechanism in place to receive rapid referral of a patient from the GP in the event of deteriorating clinical condition. 8. Advise the GP on stopping treatment (if appropriate). 9. Report serious adverse events to the MHRA. 10. Ensure that clear backup arrangements exist for GPs to obtain advice and support. General Practitioner responsibilities 1. Reply to the request for shared care as soon as practicable. 2. Prescribe apomorphine at the dose recommended after stabilisation of treatment. 3. Adjust the dose as advised by the specialist. 4. Report to and seek advice from the specialist on any aspect of patient care that is of concern and may affect treatment e.g. occurrence of side-effects or inability to administer apomorphine. 5. Refer patient to the specialist if his or her condition deteriorates. 6. Stop treatment on the advice of the specialist or immediately if an urgent need to stop treatment arises. 7. Report adverse events to the specialist and MHRA. Patient's role 1. Report to the specialist or GP if he or she does not have a clear understanding of the treatment. 2. Share any concerns in relation to treatment with apomorphine. 3. Ensure regular attendance for review and blood monitoring tests. 4. Report any adverse effects to the specialist or GP whilst taking apomorphine. 1.

SUPPORTING CLINICAL INFORMATION Parkinson’s disease is a chronic, progressive, neurological disorder that affects 1.8/1000 people in the UK. It is a relatively common disease of the elderly, with approximately 1 in 200 patients over the age of 65 years affected. The disease is characterised by resting tremors, muscular rigidity and bradykinesia (slowness of initiating and carrying out voluntary movements). The patient has a mask-like face, monotonous voice and walks with a stoop and slow shuffling gait. Current Treatment Options Levodopa (in combination with a peripheral dopa-decarboxylase inhibitor) is the corner stone of symptomatic therapy for Parkinson’s disease. Unfortunately, within 3-5 years of initiating treatment at least 50% of patients develop fluctuations with dyskinesia and end-of-dose akinesia or ‘wearing-off’. Current management strategies for fluctuating patients involve the use of controlled release formulations, and adjunct therapies such as dopamine agonists and selegiline, to provide additional symptom control. In very difficult cases subcutaneous administration of apomorphine may be required. Pharmacology Apomorphine is a dopamine D2-receptor agonist used in the management of parkinsonism, especially the control of the “on-off” effect. Although apomorphine is a morphine derivative, it has no opiate or addictive properties. Apomorphine is used in patients who suffer from disabling “off” periods, or painful dystonias, depressions, bladder dysfunction and swallowing difficulties. Many patients experience peak dose, or biphasic dyskinesias which can be as, or even more, disabling than an “off” period. In some cases, a reduction in oral medication is possible, gaining better symptomatic control of a patient’s fluctuations. Indications The treatment of disabling motor fluctuations (“on-off” phenomena) in patients with Parkinson's disease which persist despite individually titrated treatment with levodopa (with a peripheral decarboxylase inhibitor) and/or other dopamine agonists. Patient Selection Apomorphine injections are only considered suitable for Parkinson’s disease patients capable of recognising and anticipating “off” episodes in motor performance. An apomorphine challenge is necessary to determine whether a patient has a positive response, the individual dose and observe patient for side-effects e.g. postural hypotension and hallucinations. Dosage and Administration The optimal dose of apomorphine has to be determined on an individual patient basis, under specialist supervision. The dosage will vary depending on the formulation chosen. Apomorphine ampoules 10 mg/ml solution for injection or infusion is for subcutaneous use by intermittent bolus injection. Apomorphine ampoules 10 mg/ml solution for injection or infusion may also be administered as a continuous subcutaneous infusion by minipump and/or syringedriver Apomorphine is usually highly emetogenic, so all patients are treated with DOMPERIDONE 20-30 mg three times a day, starting at least 3 days prior to initiation of therapy. It is sometimes possible to withdraw this after a couple of months. The domperidone may also prevent/reduce postural hypotension. Determination of the threshold dose The appropriate dose for each patient is established by incremental dosing schedules. The following schedule is suggested:- 1mg of apomorphine HCl (0.1ml), that is approximately 15-20 micrograms/kg, may be injected subcutaneously during a hypokinetic or 'off' period and the patient is observed over 30 minutes for a motor response. If no response, or an inadequate response, is obtained a second dose of 2 mg of apomorphine HCl (0.2ml) is injected subcutaneously and the patient observed for an adequate response for a further 30 minutes. The dosage may be increased by incremental injections with at least a forty minute interval between succeeding injections, until a satisfactory motor response is obtained. The optimal dosage of apomorphine hydrochloride varies between This Shared Care Agreement should be read in conjunction with the Summary of Product Characteristics (SPC) for Apomorphine (APO-go) Date approved: December 2012 Expiry date: 31/12/2017 Royal Wolverhampton NHS Trust Wolverhampton City Clinical Commissioning Group Wolverhampton Shared Care Agreement Black Country Cluster Apomorphine (APO-go®) ESCA: For the treatment of disabling motor fluctuations (“on-off” phenomena) in patients with Parkinson's disease which persist despite individually titrated treatment with levodopa (with a peripheral decarboxylase inhibitor) and/or other dopamine agonists. individuals but, once established, remains relatively constant for each patient. Precautions on continuing treatment The daily dose of APO-go varies widely between patients, typically within the range of 3-30 mg, given as 1-10 injections and sometimes as many as 12 separate injections per day. It is recommended that the total daily dose of apomorphine HCl should not exceed 100 mg and that individual bolus injections should not exceed 10 mg. In clinical studies it has usually been possible to make some reduction in the dose of levodopa; this effect varies considerably between patients and needs to be carefully managed by an experienced physician. Once treatment has been established, domperidone therapy may be gradually reduced in some patients but successfully eliminated only in a few, without any vomiting or hypotension. Continuous Infusion Patients who have shown a good 'on' period response during the initiation stage, but whose overall control remains unsatisfactory using intermittent injections, or who require many and frequent injections (more than 10 per day), may be commenced on or transferred to continuous subcutaneous infusion by minipump and/or syringe-driver (see section 6.6) as follows:Continuous infusion is started at a rate of 1 mg apomorphine HCl (0.1 ml) per hour then increased according to the individual response. Increases in the infusion rate should not exceed 0.5 mg per hour at intervals of not less than 4 hours. Hourly infusion rates may range between 1 mg and 4 mg (0.1 ml and 0.4 ml), equivalent to 0.015 - 0.06 mg/kg/hour. Infusions should run for waking hours only. Unless the patient is experiencing severe night-time problems, 24 hour infusions are not advised. Tolerance to the therapy does not seem to occur as long as there is an overnight period without treatment of at least 4 hours. In any event, the infusion site should be changed every 12 hours. Patients may need to supplement their continuous infusion with intermittent bolus boosts via the pump system as necessary. A reduction in dosage of other dopamine agonists may be considered during continuous infusion. Contraindications Patients with respiratory depression, dementia, psychotic diseases or hepatic insufficiency Patients who have “on” response to levodopa which is marred by severe dyskinesia, hypotonia or psychotoxicity Patients who have a known hypersensitivity to apomorphine or any excipients of the medicinal product. Children and adolescents under 18 years of age. Side Effects Side-effects are rarely a problem as those who have found to have adverse effects at the challenge state are deemed unsuitable for continued treatment. The most common adverse effects are neuropsychiatric disorders, including transient hallucinations and confusion. Transient sedation may occur at the beginning of treatment which usually resolves over the first few weeks. Somnolence, dizziness and lightheadedness have also been reported. Haemolytic anaemia and thrombocytopenia have been reported; hence the need for regular blood counts. Nausea and vomiting have been reported but this is only usually due to the domperidone not being administered. Most patients experience injection site reactions, including subcutaneous nodules, induration, erythema, tenderness and panniculitis. Various other local reactions (such as irritation, itching, bruising and pain) may also occur. Monitoring Regular full blood count as haemolytic anaemia and thrombocytopenia have been reported in patients treated with apomorphine. Drug Interactions Patients selected for treatment with apomorphine are almost certain to be taking concomitant medicines for their This Shared Care Agreement should be read in conjunction with the Summary of Product Characteristics (SPC) for Apomorphine (APO-go) Date approved: December 2012 Expiry date: 31/12/2017 Royal Wolverhampton NHS Trust Wolverhampton City Clinical Commissioning Group Wolverhampton Shared Care Agreement Black Country Cluster Apomorphine (APO-go®) ESCA: For the treatment of disabling motor fluctuations (“on-off” phenomena) in patients with Parkinson's disease which persist despite individually titrated treatment with levodopa (with a peripheral decarboxylase inhibitor) and/or other dopamine agonists. Parkinson’s disease. In the initial stages of treatment with apomorphine, patients should be monitored for unusual side-effects or signs of potentiation of effect. Drugs that interfere with central amine mechanisms should be avoided if possible, however if their administration is considered essential extreme care should be taken and the patient monitored for signs of potentiation, antagonism or other unusual side effects. Drugs include: tetrabenazine, metoclopramide phenothiazines (e.g. chlorpromazine), thioxanthenes (e.g. flupenthixol) and butyrophenones (e.g. haloperidol) amphetamines papaverine It is recommended that administration of apomorphine should be avoided with other drugs known to prolong the QT interval. Vaccination The use of LIVE vaccine is not recommended during drug treatment with immunosuppressant drugs. This section may be excluded if the shared care agreement related to a drug which is not an immunosuppressant.
