What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Participants will receive Tongmai Jiangtang Capsule (TJC) in addition to standard treatment.Drug

    Intervention Agent: The study employs Tongmai Jiangtang Capsule (TJC), a traditional Chinese medicine compound formulated based on TCM theory. It has the functions of Nourishing Yin, clearing heat and activating blood circulation, and can comprehensively regulate glucose and lipid metabolism as well as improve cardiovascular and cerebrovascular functions.

    Intervention Population: The study focuses on patients with metabolic syndrome at high cardiovascular and cerebrovascular risk (HCR-MS) who meet the TCM criteria for "Qi-deficiency and Blood Stasis syndrome," reflecting personalized and precision intervention.

    Intervention Design: A long-term study design with 26 weeks of intervention followed by 26 weeks of follow-up is adopted to comprehensively assess the short-term efficacy and long-term cardiovascular benefits of TJC.

    Control Design: The study employs a double-blind, randomized, placebo-controlled method.

  • A placebo capsule that is identical in appearance, size, color, formulation, weight, taste, and smell to TJCDrug

    Participants in this Arm will receive a placebo capsule that is identical in appearance, size, color, formulation, weight, taste, and smell to TJC, in addition to standard treatment.

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 9 inclusion and 10 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: enrolling by invitation, as of the sponsor's last update on 13 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Cardiovascular death (time frame: From enrollment to the next 52 weeks). 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 NCT06908473, which also lists 2 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 13 Jun 2025.
