  Purpose
This study is a clinical trial in patients with Parkinson's disease, of a drug called Exenatide which is already licensed for the treatment of patients with Type 2 Diabetes. There have been several groups that have confirmed that Exenatide has beneficial effects on nerve cells when tested in the laboratory, that raises the possibility that Exenatide may slow down or stop the degenerative process of Parkinson's disease. In an open label trial in patients with Parkinson's disease who self administered the drug for 1 year, we have previously shown that the drug is well tolerated and shows encouraging effects on the movement and non-movement aspects of the disease, even 2 months after patients stopped administering the drug. The next step is therefore to formally evaluate whether Exenatide really is a potential "neuroprotective" drug, i.e. stops the nerve cells dying in Parkinson's disease, by conducting a double blind, placebo controlled trial.

Primary Outcome Measures:
  • Efficacy [ Time Frame: 60 weeks ]
    The primary objective is to compare the effectiveness of Exenatide versus placebo on the MDS UPDRS part 3 motor subscale in the "practically defined OFF medication state" in patients with moderate severity PD.


Secondary Outcome Measures:
  • Safety and tolerability [ Time Frame: 60 weeks ]

    • Compare differences at 48 and 60 weeks between the Exenatide and placebo trial arms in:

    • Movement Disorder Society Unified Parkinson's Disease Rating Scale part 1,2,3 and 4 On medication scores
    • Movement Disorder Society Unified Parkinson's Disease Rating Scale part 3 Motor subsection Off medication score at 48 weeks.
    • Mattis Dementia Rating scale (DRS-2).
    • Safety and tolerability of Exenatide as indicated by changes in Vital signs, weight, clinical laboratory measures and Adverse Effects


Other Outcome Measures:
  • Exploratory outcomes [ Time Frame: Compare differences at 48 and 60 weeks ]

    Exploratory outcomes:

    • Compare differences at 48 and 60 weeks between the Exenatide and placebo trial arms in:

    • Unified Dyskinesia Rating scale
    • 3 day Hauser diary of PD state (Time-On, Off, Non troublesome Dyskinesia, Troublesome dyskinesia, Asleep)
    • Montgomery and Asberg Depression Rating Scale (MADRS)
    • Parkinson's Disease 39 item Quality of life questionnaire (PDQ39)
    • Non-Motor Symptoms scale (NMSS)
    • Levodopa equivalent doses (LED)
    • Quantitative change in Dopamine Transporter availability as measured by DaTSCAN uptake between baseline and 60 week evaluations
    • Exenatide level in blood, urine every 12 weeks, CSF (at 12 and 48 weeks)
    • CSF levels of BDNF (at 12 and 48 weeks)
