Gwent Shared Care Protocol APOMORPHINE (APO-go Pen) for the treatment of disabling motor fluctuations in Parkinson’s disease Protocol No. 20 General guidance PLEASE CHECK http://www.gpmtc.wales.nhs.uk FOR THE LATEST VERSION OF THIS PROTOCOL The Gwent Partnership Medicines and Therapeutics Committee has agreed this protocol. It outlines shared care arrangements for apomorphine (given as intermittent subcutaneous injections via the APO-go Pen) for the treatment of disabling motor fluctuations in patients with Parkinson's disease (PD). It does not form a basis for the shared care prescribing of continuous subcutaneous infusions of apomorphine using an ambulatory pump. This document should be read in conjunction with: 1. The Shared Care Agreement Form (see below) 2. The Summary of Product Characteristics (Data Sheet) for APO-go Pen: http://www.medicines.org.uk/EMC/medicine/12941/SPC/APOgo+Pen+10mg+ml+Solution+for+Injection/ 1. Licensed indication The treatment of disabling motor fluctuations ('on-off' phenomena) in patients with PD which persist despite individually titrated treatment with levodopa (with a peripheral decarboxylase inhibitor) and/or other dopamine agonists. 2. Therapeutic use & Background information Apomorphine has been licensed since 1993 for use in patients with disabling motor fluctuations who are inadequately controlled with levodopa or dopamine agonists. The licence covers both subcutaneous intermittent injections and continuous subcutaneous infusions. Apomorphine is a dopamine agonist, which acts directly on D1 and D2 receptors, stimulating areas of the brain where dopamine works. It produces a similar effect to levodopa, that is, the ability to prevent and reverse disabling “off” periods. Despite its name it has no opiate or addictive properties. Apomorphine cannot be used orally because it undergoes extensive first pass metabolism (in the liver) to an inactive metabolite; for this reason it is administered subcutaneously. 1. Apomorphine may be administered as a “rescue therapy” with intermittent subcutaneous bolus injections given via a prefilled APO-go Pen or a standard 1ml syringe. 2. For those patients who experience more complex motor fluctuations, including dyskinesias, a continuous subcutaneous infusion using an ambulatory APO-go pump may be used with the APO-go PFS. In carefully selected patients who respond to the drug, apomorphine can provide a means of rescue within 5 to10 minutes of administration, thereby regaining mobility and independence. The effect usually lasts for about an hour. Apomorphine can improve quality of life and may keep patients out of costly institutional care for many years. Apomorphine should be initiated in the controlled environment of a specialist clinic. The treatment should be supervised by a Specialist team in Parkinson’s disease or Debbie Davies (Parkinson's Disease Nurse Specialist for ABHB). The patient's treatment with levodopa, with or without dopamine agonists, should be optimised before starting aporphine treatment. Patients selected for treatment with the APO-go Pen should be able to recognise the onset of their 'off' symptoms and be capable of injecting themselves or else have a responsible carer able to inject for them when required. 3. Contraindications Apomorphine is contraindicated in patients: 1. with respiratory depression 2. with dementia This Shared Care Protocol should be read in conjunction with the Summary of Product Characteristics Status: APPROVED Issue Date: September 2010 Approved by: GPMTC Page 1 of 5 Review Date: September 2012 3. 4. 5. 6. with psychotic diseases with hepatic insufficiency under 18 years of age with a known hypersensitivity to apomorphine or any excipients of the medicinal product Intermittent apomorphine treatment is not suitable for patients who have an 'on' response to levodopa, which is marred by severe dyskinesia or dystonia. 4. Typical dosage regimen (adults) By subcutaneous injection (using the APO-go pen), usual range (after initiation as below) 3 to 30mg daily in divided doses; subcutaneous infusion may be preferable in those requiring division of injections into more than 10 doses daily; max. single dose 10mg By continuous subcutaneous infusion (those requiring division into more than 10 injections daily) initially 1mg/hour daily increased according to response (not more often than every 4 hours) in max. steps of 500micrograms/hour, to usual rate of 1 to 4mg/hour (14 to 60micrograms/kg/hour); change infusion site every 12 hours and give during waking hours only (24-hour infusions not advised unless severe night-time symptoms) – intermittent bolus boosts also usually needed. Note Total daily dose by either route (or combined routes) max. 100mg In rare cases it may be necessary to give higher doses. 5. Drug interactions Check BNF Appendix 1 before coprescribing any other drug. Effects of apomorphine antagonised by antipsychotics (clozapine may be used to reduce the symptoms of neuropsychiatric complications). Effects of apomorphine possibly enhanced by entacapone Effects of dopaminergics possibly enhanced by memantine Antiparkinsonian effect of dopaminergics antagonised by methyldopa As the effects of apomorphine on the plasma concentrations of other drugs have not been studied caution is advised when combining apomorphine with drugs that have a narrow therapeutic range. 6. Adverse drug reactions All healthcare professionals have a responsibility to patients in advising/acting on suspected adverse drug reactions. Clinical condition (frequency) Management Sedation, dizziness and somnolence including sudden onset of sleep (≥1/100 to <1/10) If severe discuss Injection-site reactions including nodule formation, ulceration, erythema and tenderness. Most patients experience injection site reactions, particularly with continuous use. Other local reactions (such as irritation, itching, bruising and pain) may also occur (>1/10) Change injection sites in rotation Neuropsychiatric disturbances including confusion and visual hallucinations (≥1/100 to <1/10) Discuss with specialist Nausea and vomiting, particularly when apomorphine is first initiated (≥1/100 to <1/10) If severe or persistent discuss with specialist less common: postural hypotension, breathing difficulties, dyskinesias during ‘on’ periods (may require discontinuation), haemolytic anaemia and thrombocytopenia with levodopa, and rash; rare: eosinophilia; peripheral oedema, pathological gambling, dizziness, increased libido, and hypersexuality also reported 7. Baseline investigations Undertaken by specialist centre Coombs test (for autoimmune hemolytic anemia) FBC, LFTs, U&Es, ESR, BP and ECG This Shared Care Protocol should be read in conjunction with the Summary of Product Characteristics Status: APPROVED Issue Date: September 2010 Approved by: GPMTC Page 2 of 5 Review Date: September 2012 8. Monitoring undertaken by specialist centre Apomorphine treatment requires the involvement of a multidisciplinary team, including a Parkinson's Disease Nurse Specialist (PDNS) who regularly visits the patient at their home. Coombs test and FBC, LFTs, U&Es and BP at 6 monthly intervals. 9. Pharmaceutical aspects APO-go Pen 10mg/ml is a disposable multiple dose pen injector system incorporating a clear glass cartridge containing a clear solution for injection. Do not use if the solution in the Pen is green. Discard each APO-go Pen no later than 48 hours after first use. Patients, carers and community nurses should be made aware that apomorphine when spilt on cloths and most surfaces will leave a permanent olive green stain which is almost impossible to remove (lemon juice is reported to help). 10. Specialist centre contact information If stopping the medication or needing advice please contact Debbie Davies (Parkinson’s Disease Nurse Specialist Aneurin Bevan Health Board) 01633 234151 or 07944467611 11. Criteria for shared care Prescribing responsibility will only be transferred when: Treatment is for a specified indication and duration. Treatment has been initiated and established by the Specialist Centre and Debbie Davies (PDNS). The patient’s initial reaction to and progress on the drug is satisfactory. The patient’s general physical, mental and social circumstances are such that he/she would benefit from shared care arrangements. 12. Responsibilities of initiating specialist To provide a patient information leaflet indicating the risks and benefits associated with apomorphine therapy and to outline the shared care arrangements. To confirm patient’s understanding (and spouse/carer’s understanding as appropriate) and consent to treatment and to advise on the action to be taken in relation to potential side effects should they occur. To undertake baseline monitoring (including a Coombs test and a full blood count), initiate apomoprhine, and make any dosage adjustments. Following the apomorphine challenge, to initiate apomorphine in combination with domperidone (20mg three times daily) and optimise other antiparkinsonian drug therapy. To provide the patient with an initial supply of APO-go Pens, needles and a sharps bin sufficient for the first 4 weeks of treatment. To train the patient and /or carer in the use of the APO-go Pen device (this should include the safe storage and disposal of the Pens and sharps). To send the GP a Shared Care Agreement Form (see page 5) and invite them to participate in the shared care management of the patient – ideally patients should be at a stage where they no longer require regular domperidone. Monitor blood tests including a Coombs test and a full blood count at 6 monthly intervals. To act as a telephone contact for patients, carers and other health professionals. To see the patient in the event of any significant deterioration in their condition. To inform the GP of dosage schedule, monitoring measurements and progress of treatment after each appointment. To inform the GP if the patient fails to attend an appointment and clearly indicate that the patient is receiving apomorphine. Stop the treatment when considered to be no longer appropriate (i.e. for lack of efficacy or if adverse effects outweigh benefit). 13. Responsibilities of Primary Care To prescribe and monitor ongoing APO-go Pen therapy in collaboration with the specialist in accordance with this protocol. To inform the specialist services if the patient shows significant worsening of control of This Shared Care Protocol should be read in conjunction with the Summary of Product Characteristics Status: APPROVED Issue Date: September 2010 Approved by: GPMTC Page 3 of 5 Review Date: September 2012 symptoms or deterioration of PD. To inform the specialist services of any significant adverse reactions (and to report suspected serious adverse reactions to the MHRA using the Yellow Card scheme) or difficulties with apomorphine administration. 14. Responsibilities of patients/carer Discuss potential benefits and side effects of treatment with the Parkinson Disease Nurse Specialist (PDNS) and GP, to identify whether they have a clear picture of these from the PDNS and to raise any outstanding queries Check that where possible the specialists have provided a patient-held record or information sheet for monitoring and/or to alert other clinical staff to the treatment they are receiving. Share any concerns they have in relation to treatment with the medicine. Report any adverse effects to their specialist or GP whilst taking the medicine. Report to the PDNS or GP if they do not have a clear understanding of their treatment. Participate in the monitoring of therapy and the assessment of outcomes, to assist health professionals to provide safe, appropriate treatment. To administer their apomorphine intermittently via the APO-go Pen device and to ensure that the Pens and sharps are safely stored and disposed of. To arrange collection of full sharps bins and the supply of replacement bins (patients should telephone Gwent NHS Customer Contact Centre 01495 745656) 15. Responsibilities of all prescribers Any suspected serious adverse reaction to an established drug should be reported to MHRA via the “yellow card scheme.” http://yellowcard.mhra.gov.uk/ 16.
