Phase 1
Withdrawn
Conditions
Parkinson's Disease
Interventions
Biological: PRIM-DJ2727
Drug: Placebo (for PRIM-DJ2727)
Registration Number
NCT03026231
Lead Sponsor

Brief Summary

The purpose of this study is to characterize the intestinal flora in subjects with Parkinson's Disease (PD) and to determine safety and trends in improvements in diversity of colonic microbiome following fecal microbiota transplantation.

Microbiome Diversity in Fecal Samples s Indicated by the Shannon Diversity Index12 months
Microbiome Richness in Fecal Samples as Indicated by the Number of Taxonomies per Participant12 months
Most abundant Phylum in Fecal Sample12 months
Secondary Outcome Measures

Improvements in flora diversity by oral administration of a fecal suspension from healthy donors comparing data with untreated controls3 years
Number of bowel movements per day12 months
Neurologic functioning as indicated by score on the MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS)12 months

Subject assessment of global improvement in PD and quality of life as indicated by score the self-survey Parkinson's Disease Questionnaire 39 (PDQ-39)12 months
Memory as assessed by score on the Montreal Cognitive Assessment (MoCA)12 months
Number of participants with worsening of PD symptoms or other potential flora-mediated disorders as indicated by patient diares12 months
