What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: baseline

Qualify of life as assessed by the Parkinson's disease Questionnaire (PDQ-39)
The Parkinson's disease Questionnaire (PDQ-39) is a 39 questions self-completed questionnaire that comprises 8 domains: mobility (10 items), activities of daily living (6 items), emotional well-being (6 items), stigma (4 items), social support (3 items), cognition (4 items), communication (3 items) and bodily discomfort (3 items). All items are assumed to impact Quality of Life (QoL) and must be answered to compute scores for each dimension. Questions are answered based on experiences from the preceding month using a 5-point ordinal scoring system: 0 = never, 1 = occasionally, 2 = sometimes, 3 = often, 4 = always. Overall score ranges from 0 = never have difficulty to 100 = always have difficulty. For each of the 8 domains, the domain score is the sum of scores in the domain divided by the maximum possible score of all items in the domain, multiplied by 100. The overall score is the sum of all 8 domain scores divided by 8.

Interventions
| Intervention | Type | Arms |
|---|---|---|
| PRIM-DJ2727Twice 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 | Drug | Active group treated with healthy fecal microbiota |
| Placebo oral capsulePlacebo 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 | Drug | Placebo group |
Primary outcome
Microbiome Diversity in Fecal Samples as Indicated by the Shannon Diversity Index
Time frame: baseline
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.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Microbiome Diversity in Fecal Samples as Indicated by the Shannon Diversity Index (time frame: baseline). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03671785, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2023.
