GLP1R in Parkinson's Disease

We will include newly diagnosed patients with PD, age 40-75. Diagnosis of clinically established early PD will be made according to the new criteria set by the Movement Disorder Society (Berg D et al Mov Disord 2018). Enrolment must occur within a year from diagnosis. Before inclusion in the trial PD diagnosis must be supported by typical findings on dopamine transporter (DAT)scans.

Patients will be excluded if they have chronic inflammatory brain disorders, as verified or diagnosed on brain magnetic resonance imaging (MRI). Cognitive impairment in PD will be excluded by way of Mini Mental Status (MMS, score < 25 points) and Montreal Cognitive Assessment (MOCA, score <25 points). The patients will be excluded if they have diabetes type 2 and cancer, especially if they or family members have familiar medullary thyroid carcinoma, or multiple endocrine neoplastic syndrome type 2 (MEN 2), as well as those having manifest kidney failure (see side effects below). The patients cannot receive long-term treatment with anti-inflammatory drugs, or other experimental drugs. Patients who are pregnant or breastfeeding are excluded.
