Study Summary

The purpose of this study is to characterize the intestinal microbiome in subjects with Parkinson's disease and to determine safety and trends in improvements in diversity of colonic microbiome following administration of lyophilized PRIM-DJ2727

Primary Outcome

The Shannon diversity index is used to characterize species diversity in a community. Shannon's index accounts for both abundance and evenness of the species present. A high index value would represent a diverse and equally distributed community, and lower values represent a less diverse community. A value of 0 would represent a community with just one species. Typical values are generally between 1.5 and 3.5.

Interventions

  • DRUG PRIM-DJ2727
  • DRUG Placebo oral capsule
