Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Semaglutide has effects that include lowering blood sugar, reducing weight, and improving cardiovascular and renal outcomes, and it is now widely used in clinical practice. Given that weight loss is associated with bone loss, its effect on bone health has recently raised concerns. Therefore, the goal of this clinical trial is to learn the effect of semaglutide on bone mineral density and fractures in patients with type 2 diabetes.

The investigators will compare semaglutide combined with metformin to metformin alone to see if semaglutide treatment has effects on bone mineral density and bone turnover markers in patients with type 2 diabetes after 12 months.

The intervention group will receive semaglutide combined with metformin for 12 months, while the control group will receive metformin alone for the same duration. After 12 months of treatment, the investigators will compare the bone mineral density, fracture incidence, and levels of bone turnover markers between the two groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

The intervention group

In the intervention group, the participants will receive semaglutide combined with metformin treatment.

Group Type EXPERIMENTAL

semaglutide combined with metformin

Intervention Type DRUG

The initial dose of semaglutide is 0.25 mg once weekly. After 4 weeks, the dose is adjusted to 0.5 mg once weekly. After another 4 weeks, the dose is adjusted to 1 mg once weekly. During the same period, they will take metformin (500mg each time, three times a day) for treatment. The treatment course is 12 months.

The control group

In the control group, the participants will be treated with metformin alone (500mg each time, three times a day).

Group Type NO_INTERVENTION
