Type 2 Diabetes Mellitus
Conditions
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.
