About this study
Official title: The Study of Berberine Affecting Metabolism, Inflammation Status, Endothelial Function and Thrombotic Events in Patients With Coronary Artery Disease by Remodeling Gut Microbiota
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
Read the detailed description
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.
Blood and feces samples will be collected before and after treatment. Flow mediated dilation (FMD), HbA1C, fasting plasma glucose (FPG), lipids and cholesterol level, inflammatory factors, amino acids, bile acids and other metabolic related components and parameters will be measured. Furthermore, the change of gut microbiota will be evaluated too.

What is being measured
The primary outcome is the main question the study is designed to answer.
Endothelial function measured by Flow mediated dilation (FMD)
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.
Measured: On the baseline, 4th, 8th, 12th week of treatment
Gut microbiome
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.
Measured: On the baseline, 4th, 8th, 12th week of treatment
Fecal metabolomics profile measurement
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.
Measured: On the baseline, 4th, 8th, 12th week of treatment

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Endothelial function measured by Flow mediated dilation (FMD) (time frame: On the baseline, 4th, 8th, 12th week of treatment). The study lists 3 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 NCT04434365, which also lists 9 linked publications.
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 16 Jun 2020.
