About this study
Official title: Mechanism of Action and Real-World Study of Rosa Roxburghii Tratt Freeze-Dried Juice Powder and Its Extracts Against Carotid Atherosclerotic Plaques
This study aims to evaluate the effectiveness and safety of Rosa roxburghii freeze-dried powder in reducing carotid atherosclerotic plaques. Carotid atherosclerosis is a major cause of ischemic stroke, and current treatments have safety limitations. Rosa roxburghii, a fruit used in traditional Chinese medicine, has shown potential in lowering lipids and reducing inflammation. In this randomized controlled trial, 200 participants with carotid plaques will be assigned to either conventional therapy alone or conventional therapy plus Rosa roxburghii freeze-dried powder (3 g/day for 6 months). The primary outcomes are changes in plaque size assessed by ultrasound and serum lipid levels. Secondary and exploratory outcomes include changes in inflammatory markers, gut microbiota composition, and metabolomic profiles. The study will provide clinical evidence on the use of Rosa roxburghii as an adjunctive therapy for atherosclerosis.
Read the detailed description
Atherosclerosis, particularly carotid artery plaque, is a critical risk factor for acute ischemic stroke. Current pharmacological interventions, such as statins, are effective but have safety concerns that limit long-term use. Rosa roxburghii Tratt, a food-medicine homology plant, possesses antioxidant, anti-inflammatory, and lipid-regulating properties. Preclinical studies suggest that its active components may modulate lipid metabolism and inflammation, potentially through gut microbiota-mediated pathways.
This study is a multicenter, randomized, parallel-controlled, real-world clinical trial designed to investigate the efficacy and safety of Rosa roxburghii freeze-dried powder in patients with carotid atherosclerotic plaques. A total of 200 participants meeting the inclusion criteria will be enrolled and randomly assigned in a 1:1 ratio to either the experimental group (conventional anti-atherosclerosis therapy plus Rosa roxburghii freeze-dried powder 3 g/day orally for 6 months) or the control group (conventional therapy alone). Conventional therapy includes statins and antiplatelet agents prescribed according to standard clinical practice.
The study consists of a screening period, a 6-month treatment period, and a 2-month follow-up period. Clinical assessments are scheduled at baseline, 3 months, and 6 months. The primary outcome measures are the change from baseline in carotid plaque area assessed by ultrasound and serum lipid levels (total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol) at 6 months. Secondary outcome measures include changes in peripheral blood mononuclear cell characteristics and gut microbiota composition with metabolomic profiles. Safety outcomes include the incidence of adverse events and serious adverse events.
Biological samples (fasting blood and feces) are collected at baseline, 3 months, and 6 months for mechanistic studies. Blood samples will be used for peripheral blood mononuclear cell isolation and biomarker analysis. Fecal samples will undergo 16S rRNA sequencing and untargeted metabolomics to explore the gut microbiota-metabolite axis underlying the intervention effects. The sample size calculation assumed a 90% power and a 30% attrition rate, yielding 100 participants per group. Statistical analyses will include descriptive statistics, correlation analyses for efficacy, and safety evaluations using CTCAE criteria. This study is expected to provide robust clinical evidence on the efficacy and mechanism of Rosa roxburghii as an adjunctive therapy for carotid atherosclerosis, potentially offering a safe and accessible option for stroke prevention.

Questions about this trial
What is this clinical trial studying?
A study testing Rosa Roxburghii Freeze-Dried Powder and Conventional Anti-Atherosclerosis Therapy in people with Carotid Artery Plaques and Atherosclerosis, run by Xiangya Hospital of Central South University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 25 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Change in Carotid Plaque Area (time frame: Baseline and 6 months after treatment initiation). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 25 Sep 2026.
