Description as written by the study sponsor.

Fifty patients with early stage Multiple System Atrophy (MSA) will be recruited and randomised to receive Exenatide injections, or to act as controls in this open label trial. For half of the patients, Exenatide will be given as a once weekly subcutaneous injection in addition to participant's regular medication. All patients will continue to receive standard of care treatment for MSA. Detailed assessments will be made of all patients at baseline and periodically for a total of 48 weeks. The primary endpoint will be the difference in total Unified Multiple System Atrophy Rating Scale (UMSARS) score (Parts I and II) at 48 weeks comparing Exenatide treated to best medically treated patients (controls). Secondary measures will include adverse event reports, self-completed questionnaires, and blood test results. Aside from these assessments, all patients will continue any regular MSA medications throughout the trial with adjustments made only according to clinical need. Standard of care treatment for patients on non IMP arm will be dependant on the patients individual symptoms - there is no broad standard treatment for every patient.
