Evaluation of Efficacy and Safety of Combination Therapy of Henagliflozin Proline, Retagliptin and Metformin in New Diagnosed Type 2 Diabetes Patients

This study evaluated the efficacy and safety of initial combined treatment of Henggliptin, Retagliptin and Metformin by including new type 2 diabetes patients. This study is a multicenter, randomized, open label, positive control study. It is planned to include 160 new type 2 diabetes patients who meet the inclusion criteria of the study. The study is divided into three stages: screening period (V0, -14d-0), treatment period (V1-V8, D1-24w) and safe follow-up period (V9, 28w), with a total of 10 planned visits. This study was divided into an experimental group and a control group. The experimental group received a one-time addition of 10 mg qd of Henggliptin, 100 mg qd of Regagliptin, and 500mg of Metformin. The control group was first treated with metformin. If the blood sugar level did not meet the standard (fasting blood glucose (FPG)\>7mmol/L, postprandial blood glucose (PPG)\>10mmol/L), Henggeliflozin 10 mg qd was sequentially added. If the blood sugar level did not meet the standard after 4 weeks, Regagliptin 100 mg qd was added. During the follow-up period, evaluate blood glucose control, pancreatic islet function, and safety in both groups of patients.
