Brief Summary

The primary objective of this trial is to evaluate the efficacy of different doses and frequencies of administration of TG103 injection in the treatment of type 2 diabetes.

Detailed Description

This trial is a randomized, double-blind, placebo-parallel, Dulaglutide-controlled，multicenter phase Ⅱ clinical trial. The whole trial consists of two parts, Part A and Part B, and 240 subjects are planned to be enrolled. Part A will be divided into three groups: TG103 15 mg group, TG103 22.5 mg group and placebo group, given once every two weeks (Q2W); Part B will be divided into four groups: TG103 7.5mg dose group, TG103 15 mg dose group ,placebo group and Dulaglutide group, once a week (QW). After Part A enrollment is completed, Part B will continue to be enrolled. The trial will include a screening period of up to 2 weeks, an initiation period of 2 weeks, a double-blind treatment period of 16 weeks, and a safety follow-up period of 3 weeks.
