Overview
Brief Summary
Observational cross-sectional study in PD patients and healthy controls (HC) using an investigational medical device consisting of a passive small intestine microbiome aspiration (SIMBA) system (capsule) that is ingested orally and recovered together with the stools (home recovery) together with blood sampling (during the onsite visit).
Detailed Description
Participants will be swallowing two SIMBA capsules which allows for minimally-invasive sampling of the microbiome and metabolome deep in the small intestine. Researchers will use the capsule samples to determine the small intestinal microbiome and metabolomic signatures in luminal fluid samples from the small bowel in Parkinson Disease (PD) patients compared to healthy controls (HC).

Outcomes
Primary Outcomes
Difference in microbiome profile of small intestine samples between groups
Time Frame: Baseline
Functional dysbiosis profile of the small intestinal microbiota of Parkinson's Disease patients compared to age-matched neurotypical controls, as determined by whole metagenome shotgun sequencing based profiling
Secondary Outcomes
- Difference in blood metabolome composition between groups(Baseline)
- Correlation between the observed small intestine microbiome profile and blood metabolome composition, including, in PD subjects, levodopa pharmacodynamics(Baseline)
