About this study

Type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) are growing public health challenges. Early intervention in mild T2DM and IGT is essential to prevent disease progression and severe complications. Traditional Chinese Medicine (TCM) provides a potential therapeutic approach.

Sanggua tablets, a TCM formula composed of mulberry leaf, bitter melon, kudzu root, Chinese yam, and cassia seed, embody TCM principles of clearing heat, generating body fluids, tonifying the spleen and stomach, and nourishing the lungs and kidneys. Modern studies show that Sanggua tablets effectively lower blood glucose and improve lipid profiles through components like mulberry polysaccharides and bitter melon saponins. These findings suggest their potential as an alternative or complementary therapy for mild T2DM and IGT.

This study will conduct a randomized, double-blind, placebo-controlled, parallel-group clinical trial among patients with IGT and mild T2DM. Participants will receive a 16-week intervention with Sanggua tablets. The primary outcome is glycated hemoglobin (HbA1c), with secondary outcomes such as fasting blood glucose (FBG), fasting insulin (FINS), HOMA-IR, lipid profiles and so on. Safety will be closely monitored. Additionally, fecal samples will be collected for 16S rDNA sequencing to explore the role of gut microbiota in the therapeutic effects of Sanggua tablets. This study aims to provide evidence for the clinical application and development of Sanggua tablets as a novel TCM therapy.

Read the detailed description

Type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) are significant public health concerns, with rising prevalence rates globally. Treating mild T2DM and IGT is crucial to prevent disease progression and reduce the risk of severe complications such as cardiovascular diseases. Traditional Chinese Medicine (TCM) offers a promising approach in this context.

Sanggua tablets, a TCM formula, consist of mulberry leaf, bitter melon, kudzu root, Chinese yam, and cassia seed. These ingredients work synergistically to achieve the TCM therapeutic principles of clearing heat and detoxifying, generating body fluids and moistening dryness, tonifying the spleen and stomach, and nourishing the lungs and kidneys. Modern pharmacological studies have shown that Sanggua tablets have significant therapeutic potential. Their components, such as mulberry polysaccharides and bitter melon saponins, have been proven to lower blood glucose levels by promoting glycogen synthesis and inhibiting glucose absorption. Additionally, they have demonstrated hypolipidemic effects, improving lipid profiles and potentially preventing atherosclerosis.

Clinical and experimental evidence suggests that Sanggua tablets can effectively improve insulin resistance and regulate lipid metabolism. These findings highlight their potential as an alternative or complementary therapy for mild T2DM and IGT. Further research is needed to elucidate their mechanisms of action and optimize their clinical application.

This study proposes to employ a randomized, double-blind, placebo-controlled, parallel-group clinical trial design. The study population will consist of patients with IGT and mild T2DM. Participants will undergo a 16-week intervention with Sanggua tablets. The primary outcome is glycated hemoglobin (HbA1c), with secondary outcomes such as fasting blood glucose (FBG), fasting insulin (FINS), HOMA-IR, lipid profiles and so on. Safety indicators will also be closely monitored. The clinical efficacy of Sanggua tablets will be re-evaluated through these measures. Additionally, to explore its mechanism of action, fecal samples will be collected from participants for 16S rDNA sequencing to investigate the role of gut microbiota. This study aims to provide evidence for the clinical application and potential development of Sang Gua tablets as a Category 1.1 innovative traditional Chinese medicine.

Based on calculations using the PASS 15 software, a total of 84 participants are required for enrollment, with 42 participants in each group.

Initially screened participants will undergo baseline assessments during the screening period (V0, from Day -7 to Day 0) to determine their eligibility based on the inclusion and exclusion criteria. Randomization of eligible participants and the preparation of randomization envelopes will follow the principles of randomized clinical trial design. Participants meeting the inclusion and exclusion criteria will be randomly assigned to two groups in a 1:1 ratio, receiving either conventional treatment plus Sanggua tablets or conventional treatment plus placebo. Both Sanggua tablets and the placebo will be manufactured by Wuhan Jianmin Dapeng Pharmaceutical Co., Ltd. Random numbers generated using SAS software will be used to determine the codes for participants in the two groups. Two copies of the randomization envelopes will be prepared, sealed, and separately stored by the investigator and the person in charge of the clinical study. After 16 weeks of treatment, the efficacy and safety of the interventions will be evaluated.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Sanggua tablets in people with Diabetes Mellitus, Type 2 and Impaired Glucose Tolerance, run by Tongji Hospital at 1 site in China.

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 4 inclusion and 13 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: looking for participants now, as of the sponsor's last update on 6 Oct 2026. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

Contact Gang Yuan, Professor (0086-027-13871523102, gangyuan@tjh.tjmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Hemoglobin A1c (HbA1c, %) (time frame: The percentage of glycated hemoglobin will be measured at baseline (V1) and at the end of the treatment period(Week 16 ,V5).). 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 NCT06964620.

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 6 Oct 2026.
