About this study
Official title: Developing Precision Microbiota-Based Cocktail Modification Therapy to Delay the Progression of Parkinson's Disease - Use Preclinical Human Trials to Confirm the Impact of the Optimal "Probiotic Y7, Tryptophan and Branched-chain Amino Acid" Cocktail Formula on Early Stage Parkinson's Disease Patient
Preclinical human trials will be utilized to validate the research direction, followed by clinical trials to assess the impact of a cocktail formula product containing the optimal probiotic Y7 combined metabolites on motor, cognitive, and non-motor functions in early Parkinson's disease patients. The study aims to recruit 120 patients (stage 1-3) and employ a two-arm, randomized controlled trial (RCT) design, dividing subjects into intervention and control groups for a 12 weeks trial period. Commercial development will be contingent upon the clinical trial outcomes, evaluating whether the product offers clinical benefits such as delaying Parkinson's disease progression in motor, cognitive, and non-motor functions. Additionally, a personalized and precise prognosis prediction model for Parkinson's disease will be established. This model will gather comprehensive clinical data, including motor function assessments (functional tests, UPDRS), biochemical markers, questionnaire responses, and genotype data (TPM array), as well as metabolite and microbial data. Through integrated analysis of this biological information using machine learning techniques, a personalized and accurate prognosis prediction model for Parkinson's disease will be developed. This model will predict the disease status of PD patients 12 weeks later, accounting for factors such as cocktail therapy. The results will empower PD patients to understand their individual disease progression and treatment prognosis, enabling them to prepare accordingly. Moreover, this model will aid researchers in identifying patient profiles more likely to benefit from treatment, thereby enhancing the evaluation of the efficacy and applicability of cocktail therapy.

The Mini-Mental State Examination is used to assess global cognitive function. The total score ranges from 0 to 30, with higher scores indicating better cognitive performance and lower scores indicating greater cognitive impairment.
Measured: Baseline and Week 12 after intervention.
Change from Baseline to Week 12 in Non-Motor Symptoms Scale Score in Patients with Parkinson's Disease
The Non-Motor Symptoms Scale is used to assess the frequency and severity of non-motor symptoms in patients with Parkinson's disease. Higher scores indicate greater non-motor symptom burden and worse clinical condition.
Measured: Baseline and Week 12 after intervention.
Change from Baseline to Week 12 in Parkinson's Disease Questionnaire-39 Score in Patients with Parkinson's Disease
The Parkinson's Disease Questionnaire-39 is used to evaluate health-related quality of life in patients with Parkinson's disease. Scores are transformed to a 0 to 100 scale, with higher scores indicating poorer quality of life.
Measured: Baseline and Week 12 after intervention.
Change from Baseline to Week 12 in Parkinson's Disease Sleep Scale Score in Patients with Parkinson's Disease

Change from Baseline to Week 12 in Bristol Stool Scale Score in Patients with Parkinson's Disease
The Bristol Stool Scale is used to classify stool form. Scores range from 1 to 7, with lower scores indicating harder stools and higher scores indicating looser stools. Scores around 3 to 4 generally indicate more normal stool form.
Measured: Baseline and Week 12 after intervention.
Change from Baseline to Week 12 in Mini Nutritional Assessment Score in Patients with Parkinson's Disease
The Mini Nutritional Assessment is used to evaluate nutritional status. Higher scores indicate better nutritional status, whereas lower scores indicate increased risk of malnutrition or poorer nutritional condition.
