Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study intervention is administration of GLP1-agonist Exenatide extended release (Bydureon) 2mg subcutaneously weekly in patients with a dual diagnosis of Parkinson's Disease and Type 2 Diabetes Mellitus. The study intervention will be administered for a total of 12 months. Patients will be monitored for their Parkinson's symptoms and glycemic control at baseline, 3 months, 6 months and 12 months.
Intervention code [1] 317491 0
Treatment: Drugs
Comparator / control treatment
The control group will receive no treatment (ie. their normal treatment regimen will be unaltered). This normal treatment regimen is their prescribed diabetic and Parkinson's drugs recorded at enrolment, as determined by their regular treating GPs and specialists. Patients will be monitored for their Parkinson's symptoms and glycemic control at baseline, 3 months, 6 months and 12 months.

Summary
Brief summary
Parkinson’s Disease (PD) is a progressive neurodegenerative condition that is associated with significant morbidity and loss of independence. Currently, there are few avenues of treatment and even the most potent dopamine-replacement therapies, whilst alleviating some cardinal symptoms, do not alter the underlying disease process or interfere with the progression of the disease. This study will address the potential use of GLP-1 agonists, approved for the use of Type 2 Diabetes, as a therapeutic option. Pre-clinical and human studies have been released that show:

(1) The shared mechanism of Parkinson's Disease and Type 2 Diabetes
(2) The neuro-protective effects of GLP-1 agonists in Parkinson's Disease

However, this study will be the first to analyse this effect in patients with a dual diagnosis of Type 2 Diabetes and Parkinson's Disease. A positive outcome from this study has the clinical potential for becoming the basis for a larger scale randomised-control trial and adjusting the existing diabetes management of this patient population. Both disease processes could be targeted with a medication that is already PBS-listed and the standard of care for one.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
There is no current plan to make individual participant data publicly available. Participant data will be coded and re-identifiable. The sample size is small and participants will be recruited from a single site, such that patient confidentiality may be jeopardised by releasing this information.
