Basic Information

• Recruitment Status: RECRUITING

• Total Enrollment: 64 participants
• Study Classification: INTERVENTIONAL

Brief Summary

The goal of this clinical trial is to learn if SGLT2 inhibitor Henggliflozin works to improve glucose variability in type 2 diabetes and if Henggliflozin can benefit immunosenescence.

The main questions it aims to answer are:

Does Henggliflozin as an add on treatment works to improve blood glucose fluctuation in type 2 diabetes? Does Henggliflozin has extra benefits like improve immunosenescence beyond hypoglycemic effects? Researchers will compare Henggliflozin to a placebo to see if Henggliflozin can improve glucose variability and immunosenescence.

Participants will:

Take Henggliflozin or a placebo every day for 16 weeks. Receive weekly follow-up calls to guide them in adjusting their insulin doses. Return for an on-site visit at 4 weeks and 16 weeks. Take a continuous glucose monitoring (CGM) for 7 days at the Visit 1 and at the end of the study.

Detailed Description

With the rising prevalence of diabetes, complications associated with the disease are becoming a significant threat to human health. The primary goal of diabetes treatment is to delay the onset of macrovascular and microvascular complications and to reduce cardiovascular disease (CVD)-related mortality. Numerous clinical studies have explored the relationship between glycemic variability (GV) and the risk of macrovascular disease. Recent research has shown that GV is closely associated with endothelial cell damage, which represents an early stage of atherosclerosis and serves as a predictive factor for CVD.

The mean amplitude of glycemic excursions (MAGE), a marker of daily GV related to postprandial hyperglycemia or hypoglycemia, is a critical determinant of the severity of coronary artery disease and an independent predictor of mortality risk. Over the long term, reducing daily GV can help lower cardiovascular events and mitigate cognitive decline in patients. Therefore, controlling GV is particularly important in reducing the risk of cardiovascular disease.

While there is no strong evidence yet to suggest that suppressing GV can directly reverse cardiovascular events, some studies indicate that antidiabetic medications that reduce GV can improve surrogate markers of cardiovascular risk factors. Sodium-glucose cotransporter 2 (SGLT2) inhibitors lower blood glucose by promoting glucose excretion through urine. Research has demonstrated that SGLT2 inhibitors can reduce cardiovascular risks; however, studies on their effect in suppressing GV remain insufficient.

This study is a multicenter, randomized, double-blind controlled trial aiming to enroll 64 participants with type 2 diabetes.

Eligible participants will be randomly assigned to one of two groups in a 1:1 ratio:

• Henggliflozin Group (n=32): Henggliflozin 10 mg, once daily.
• Placebo Control Group (n=32): Placebo, once daily.

Upon enrollment, at Visit 1 (baseline), overnight fasting blood and urine samples will be collected, and glucose levels will be monitored for 3-5 days using a continuous glucose monitoring (CGM) system. After the preliminary assessment, participants will receive either Henggliflozin 10 mg or a placebo once daily by oral administration for up to 16 weeks.

During the treatment period, weekly follow-up calls will be conducted to guide participants in adjusting their insulin doses until fasting blood glucose (FBG) reaches the target level (<7 mmol/L). Participants will return for an on-site visit at 4 weeks, during which medications will be retrieved, and relevant information recorded. Other antidiabetic medications, such as metformin, sulfonylureas, glinides, thiazolidinediones, or α-glucosidase inhibitors, may continue to be used at unchanged doses throughout the study. Participants will be encouraged to maintain their dietary and exercise regimens. If there is a risk of hypoglycemia, insulin doses may be reduced.

At the end of the 16-week treatment period, medications will be retrieved again, and fasting blood and urine samples will be collected. Glucose monitoring will be repeated using the CGM system. A safety follow-up call will be conducted two weeks after the end of the study.
