简要总结
The purpose of this study is to conduct a single-center, randomized, open-label, controlled, dose-escalating, parallel-group study, evaluating the effects and change of endothelial function and gut microbiota after berberine administration in patients with stable coronary artery disease who are at > 8 but ≤ 40 weeks after elective percutaneous coronary intervention
详细描述
In the present study, about 48 patients with stable coronary artery disease who are at > 8 but ≤ 40 weeks after elective percutaneous coronary intervention. The total study duration is expected to be approximately 14 weeks per patient, including a screening period, a 12±1 week treatment period, Randomization was computer generated. After screening, eligible subjects will be randomly assigned into one of the following two groups: Berberine+therapy Arm or Standard therapy Arm. The primary objective is to determine whether a combination of berberine and coronary artery disease standard therapy is preferable to either berberine alone or standard therapy alone.
The visit schedule will be as follows:
Visit 1: Day -7 to Day -1, Screening/Enrolment; Visit 2: Day 1, Randomization/First dose; Visit 3: Week 4±1, Dose adjustment 1, BBR (100mg, tid); Visit 4: Week 8±1, Dose adjustment 2, BBR (200mg, tid); Visit 5: Week 12±1, End of Treatment (EOT) /Last dose, BBR (300mg, tid); Safety visit.
We perform cross-sectional comparisons between the two arms and longitudinal comparisons within each arm to evaluate the indicators as follows:
- . Endothelial function, as measured by Flow mediated dilation (FMD) from baseline to 12-week follow-up;
- . Gut microbiota, as sequenced by metagenomic sequencing from baseline to 12-week follow-up.

结局指标
主要结局
Gut microbiome
时间窗: On the baseline, 4th, 8th, 12th week of treatment
At baseline, we evaluate the bacterial diversity, different species, different genes, and different metabolic pathways in the BBR+Standard therapy group and the Standard therapy group . In addition, we mainly focused on α and β diversity variation in the remaining 3 visits of BBR+Standard therapy subjucts. Taxonomy alteration and bacterial metabolic pathways after BBR treatment were also observed.
Fecal metabolomics profile measurement
时间窗: On the baseline, 4th, 8th, 12th week of treatment
In aid of LC/MS and GC/MS technique, we will measure the metabolomics molecular profile in fecal samples at baseline, 4th, 8th, 12th week. We aimed to detect the profile of short chain fatty acids including Acetic acid, Propanoic acid, Isobutyric acid, Butyric acid, Ethylmethylacetic acid, Isovaleric acid, Valeric acid, 2-methylvaleric acid, 3-methylvaleric acid, 4-methylvaleric acid, Hexanoic acid-SCFA and 3_Hydroxyisovaleric acid.
Endothelial function measured by Flow mediated dilation (FMD)
时间窗: On the baseline, 4th, 8th, 12th week of treatment
Flow-mediated vasodilation measurement in the brachial artery was performed with subjects in the supine position for the evaluation of endothelial function. All imaging was performed by a single, highly skilled sonographer who was unaware of the study assignment.brachial artery diameter was imaged with a 5-12-MHz linear array transducer ultrasound system at a location 3 to 7 cm above the right elbow. The brachial artery diameters at baseline (D0) and after reactive hyperemia (D1) and sublingual nitroglycerine (D2) were recorded. The flow-mediated vasodilation \[(D1-D0)/D0×100%\] was used as a measure of endothelium-dependent vasodilation.
次要结局
- Inflammatory factor levels(On the 12th week of treatment)
- Blood glucose levels(On the baseline, 4th, 8th, 12th week of treatment)
- Blood lipid levels(On the baseline, 4th, 8th, 12th week of treatment)
