Outcome Measures

Primary Outcomes (13)

  • Microbiome Diversity in Fecal Samples as Indicated by the Shannon Diversity Index

    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.

Study Arms (2)

Active group treated with healthy fecal microbiota

EXPERIMENTAL
Drug: PRIM-DJ2727

Placebo group

EXPERIMENTAL
Drug: Placebo oral capsule

Interventions

Twice filtered fecal microbiota product from three screened healthy donors will be lyophilized and encapsulated in enteric-coated capsules. Each dose of enteric coated capsules consists of 60 grams of stool and will be administered orally twice-weekly for 12 consecutive weeks

Active group treated with healthy fecal microbiota

Placebo capsule will be identical to PRIM-DJ2727 but will not contain intestinal bacteria. The placebo will consist of Lactose (spray-dried United States Pharmacopeia (USP) 64.385gm), food color, powdered Black, Brown, and Yellow in the enteric capsules. Placebo will be administered orally twice-weekly for 12 consecutive weeks

Eligibility Criteria

Age55 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented diagnosis of Parkinson's Disease (PD) for less than or equal to 10 years based on the United Kingdom Brain Bank Criteria and the Modified Hoehn-Yahr (H\&Y) staging system of less than 3 in the "OFF medicine" state of at least 8-12 hours (subjects should have an asymmetric and unilateral symptoms onset).
  • Mild microsomia to anosmia (The University of Pennsylvania Smell Identification Test (UPSIT) less than 33), which is supportive of idiopathic PD.
  • Robust response to dopaminergic therapy (defined as greater than 33% reduction in symptoms (on the Unified Parkinson's Disease Rating Scale part III (UPDRS-III)) when measured in the ON medicine state compared to OFF state.
  • Subject has a history of constipation.
  • Sexually active male and female subjects of child-bearing potential agree to use an effective method of birth control during the study.
  • Female subjects of child-bearing potential must have a negative urine Qualitative Human chorionic gonadotropin (hCG) pregnancy test at enrollment and on the Week 1, Day 1 of the Treatment prior to administration of study drug.
  • Willing and able to sign an informed consent form and attend study assessments and follow ups.
  • Subject has an attending physician who will provide non-transplant care for the subject.
  • Subject is able to maintain a stable Parkinson's therapy medical regimen during participation in the study.

You may not qualify if:

  • Unable to take multiple capsules orally.
  • Montreal Cognitive Assessment (MoCA) Score less than or equal to 23.
  • Atypical, vascular or drug-induced Parkinsonism.
  • Clinical features of psychosis or refractory hallucinations.
  • Unstable Parkinson's disease symptomatic therapy (defined as recent changes or additions to the PD regimen).
  • Compromised immune system (e.g. primary immune disorders or clinical immunosuppression due to a medical condition or medication e.g. taking systemic steroids greater than 20 milligrams (mg) a day or prednisone-equivalent)
  • Receipt of systemic non-topical antibiotic therapy currently or within 14 days of enrollment.
  • Prior Deep Brain Stimulation, or surgical intervention for PD, intravenous glutathione therapy or stem cell therapy.
  • History of medium or large vessel cerebrovascular accidents.
  • History of use of an investigational drug within 90 days prior to the screening visit.
  • Positive results for human immunodeficiency virus (HIV) or Hepatitis B / C.
  • Current history for active states of Inflammatory bowel disease, Irritable bowel syndrome, microscopic colitis, celiac disease, short gut syndrome, colostomy, colectomy, gastrointestinal fistulae or strictures.
  • History of significant uncontrolled systemic disease that in the opinion of the study investigator could interfere with study participation and/or objectives.
  • Life expectancy of less than 1 year.
  • In the opinion of investigator, subject for any reason, should be excluded from the study
