Overview
The efficacy, safety and post-treatment disease control will be compared between groups of continuous subcutaneous Beinaglutide infusion and continuous subcutaneous insulin infusion (CSII) in adult patients with newly diagnosed type 2 diabetes.
Description
Based on the dual roles of glucagon-like peptide 1 (GLP-1) in regulating fasting blood glucose and postprandial blood glucose secretion, we adopted a combinational therapeutic model and will administer drug treatments during meals. Newly diagnosed type 2 diabetic patients will be administered continuous subcutaneous Beinaglutide injections using a pump device. The efficacy, safety and disease control after terminating the drug treatments will be compared to those of patients who receive CSII treatment.
This is a national-level, multicenter, randomized, open study with parallel controls. The study consists of two phases:
a 8-week treatment phase and a 12-week post-treatment follow-up period.

- Subjects who have not taken antidiabetic medications or have used oral antidiabetic medications for less than 3 months and have discontinued for more than 1 month (calculated from the date of signing the informed consent form).

- Presence of other severe diseases that may interfere with the study, as judged by the investigator.
- Pregnant or breastfeeding women.
- Poor compliance, as judged by the investigator, and inability to complete the study as required.
- Inability to undergo continuous pump infusion: subjects allergic to subcutaneous infusion tubes or adhesive tape; subjects unwilling to have long-term subcutaneous infusion tubes or continuous pump use; subjects with psychological aversion to pump therapy; subjects or their families lack relevant knowledge and are unable to master the use after training; subjects with severe psychological disorders or mental abnormalities; subjects who are unable to care for themselves and have no caregivers.
- Any other factors deemed unsuitable for participation in the study by the investigator.
