The Clinical Problem A 67 year old man with a 10 year history of PD presents with increasing walking difficulties and has developed worsening fluctuations in the control of his motor symptoms. He was originally treated with ropinirole and levodopa was added after 3 years as his symptoms worsened. He began to notice ‘wearing off’ 4 years ago and despite levodopa fractionation, addition of entacapone and rasagiline, he is spending 5 hours a day ‘OFF’, and has developed moderately severe peak dose dyskinesias. Tolcapone resulted in severe diarrhoea. Prescribing information and SPC can be found on the landing page of the extranet site

Overview Importance of early identification of patients failing on conventional medications When do we have conversations with patients? Which patients are likely to benefit? What benefits can be expected? How do we select one device-aided therapy over another? Prescribing information and SPC can be found on the landing page of the extranet site

Facts All patients that are suitable for advanced therapies now have access to them Not all patients with access to advanced therapies are referred in a timely fashion Result: some patients who would benefit are referred too late and some never at all Prescribing information and SPC can be found on the landing page of the extranet site

Lack of information and access to advanced treatment for PD patients - Survey Swedish survey of >3000 PD patients, ~ ⅓ had advanced PD Three quarters had heard of advanced therapies but said they were ‘denied’ treatment < 30% of respondents with advanced disease had heard about one or other of the therapies from their doctor directly Lökk J. J Multidiscip Healthc. 2011; 4: Prescribing information and SPC can be found on the landing page of the extranet site

The ‘Right’ Therapy at the ‘Right’ Time How do I recognise the patient who will not benefit from further adjustments to conventional therapy? How do I decide which therapy is most likely to benefit a particular patient? Prescribing information and SPC can be found on the landing page of the extranet site

Discussion At what point in the patient’s journey do we have conversations about future advanced therapies? Prescribing information and SPC can be found on the landing page of the extranet site

Tips for identifying (not missing!) suitable patients Care plan Persistent failure to be able to perform ADLs consistently in spite of ‘optimised’ therapy Young onset patients particularly at risk – Wearing off questionnaire Avoid strict limits as to daily OFF time needed for referral Worth PF.

Prerequisites for consideration of advanced therapies Idiopathic Parkinson’s disease Clear levodopa-responsiveness Exclude frank dementia, chronic hallucinosis / psychosis Unrealistic expectations – Levodopa-unresponsive axial symptoms – NMS – Not a cure Worth PF. Pract Neurol. 2013; 0: doi: /practneurol Prescribing information and SPC can be found on the landing page of the extranet site

Levodopa-unresponsive axial symptoms Freezing of gait (FOG) in the ON state Dysarthria Dysphagia Falls because of loss of postural reflexes Worth PF. Pract Neurol. 2013; 0: doi: /practneurol Prescribing information and SPC can be found on the landing page of the extranet site

Common Themes Infusion therapies get round problem of delayed gastric emptying Allow reduction in other PD medications 24 hour therapy unlicensed but possible Continuous (dopaminergic) stimulation Prescribing information and SPC can be found on the landing page of the extranet site

‘Known knowns’ or ‘unknown unknowns’? With respect to these three therapies, what are the comparative: – Efficacies? – Adverse event profiles? – QoL data? – Cost effectiveness data? – Long term efficacies? Prescribing information and SPC can be found on the landing page of the extranet site

Review Conclusions Systemic review of apomorphine infusion, levodopa infusion and deep brain stimulation in advanced Parkinson's disease No randomised trials comparing three treatment modalities Selection of a given therapy depends on patient and clinician preference Clarke CE, Worth P, Groset D, Stewart D. Parkinsonism and Related Disorders. 2009; 15: Prescribing information and SPC can be found on the landing page of the extranet site

What benefits can patients expect from each therapy? All 3 therapies aim to provide a: Reduction in OFF time and increase in ON time Reduction in dyskinesia Improved quality of life Worth PF.

Conclusions As Parkinson’s progresses, increasing complexity of conventional treatment may fail to control symptoms satisfactorily Advanced therapies can improve motor fluctuations and dyskinesias and improve quality of life Early identification of patients is vital – don’t let them miss the boat Each treatment has a distinct profile that must be matched to individual patients Prescribing information and SPC can be found on the landing page of the extranet site
