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
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

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.

Motor function as characterized by Unified Parkinson's Disease Rating Scale (UPDRS) Total Score
UPDRS is a disability and impairment scale for PD progression and consists of 4 sections; I: evaluation of mentation, behavior, and mood (13 questions) II: evaluation of activities of daily living including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food (13 questions) III: motor examination (33 scores based on 18 questions with right, left or other body distributions scores) IV: motor complications (6 questions) All items have 5 response options: 0 = normal, 1 = slight (symptoms/ signs with sufficiently low frequency or intensity to cause no impact on function), 2 = mild (symptoms/ signs of frequency or intensity sufficient to cause a modest impact on function, 3 = moderate (symptoms/ signs sufficiently frequent or intense to impact considerably, but not prevent function), 4 = severe (symptoms/ signs that prevent function). Total Score ranges from 0 to 260, with higher scores indicating a worse outcome.

Cognitive domains characterized by using Montreal Cognitive Assessment
MoCA is a rapid screening instrument for mild cognitive dysfunction. It assess different cognitive domains: attention and concentration, executive functions, memory, language, visuo-constructional skills, conceptual thinking, calculations, and orientation. The total score ranges from 0 to 30; a score of 26 or above is considered normal. MoCA will be performed at the enrollment for baseline and the clinic visit on 9 month for study endpoint assessment, and early termination visit (if applicable).

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.

Anxiety as assessed by the Parkinson Anxiety Scale (PAS)
The Parkinson Anxiety Scale (PAS) is an anxiety measure scale for use in PD patients. This is a 12-item observer or patient-rated scale with three subscales, for persistent and episodic anxiety, and avoidance behavior. Items are scored on a 5-point Likert scale, with '0' meaning 'not or never' and '4' meaning 'severe or almost always'. Total score ranges from 0 to 48, with higher scores indicating worse outcomes.

Change in gastric emptying time (GET) as assessed by the Smart Pill® (SP) Wireless pH/pressure recording capsule
Smart Pill will be used to assess gastrointestinal dysmotility in PD patients before and after 12- week treatment. Smart Pill will be administered first during the run-In period clinic visit and again at Week 13 clinic visit following the completion of 12-week treatment. After an overnight fast, subjects will ingest the Smart Pill capsule with a nutrient bar (Smart Bar, 243 kcal) and will be instructed to wear a data receiver for 5 days or until the expulsion of the Smart Pill. After expulsion of the Smart Pill in approximately 5 days, subject will return the data receiver. Data receiver can either be dropped by or mailed via FedEx to the study site. Changes in gastric emptying time (GET), small bowel transit time (SBTT), colon transit time (CTT), small/ large bowel transit time (SLBTT) and whole gut transit time (WGTT) will be assessed by parameters established by the company providing the Smart Pill capsule.
