efficacy and safety of chiglitazar added to glargine in patients with type 2 diabetes

Conditions: Efficacy and Safety of Chiglitazar Sodium in the Treatment of T2DM Patients; Metformin Combined With Insulin Glargine in the Treatment of Type 2 Diabetes Patients Who Still Have Poor Hypoglycemic Effect; 128 Patients Were Randomly Assigned 1:1; Metformin and Insulin Glargine Combined With Chiglitazar Sodium Tablets 48mg/ Day Group; Metformin and Insulin Glargine Combined With Placebo Group; InvestigatorInitiate Trial; Changes in HbA1C From Baseline at 18 Weeks of Treatment

Summary: the goal of this clinical trial is to evaluate the efficacy and safety of chiglitazar added to patients with type 2 diabetes who do not respond well to metformin combined with insulin glargine. the main question it aims to answer are: • t2dm patients still cannot effectively control their blood sugar with the combination of insulin and metformin. the combination of follow-up treatment and hypoglycemic drugs is worth exploring, and it is necessary to explore and confirm the combination of effective and safe drugs for insulin resistance on the basis of the above treatment plans. participants will be asked to receive either chiglitazar or placebo in addition to metformin and insulin glargine 18 weeks. researchers will compare placebo groups to see if the effective effect and safety indicators of chiglitazar for reducing insulin dosage, lowering blood sugar, regulating blood lipids.

t2dm patients using insulin combined with metformin dual therapy regimen, still can not have effective control of blood sugar, the combination of follow-up treatment and hypoglycemic drugs is worth exploring, and it is necessary to base on the above treatment plans to explore and confirm the treatment of effective and safe drugs for insulin resistance. this study investigated the efficacy and safety of metformin combined with insulin glargine in the treatment of type 2 diabetes mellitus (t2dm) in patients who still have poor hypoglycemic effect, plus chiglitazar 48mg/ day for 18 weeks. a total of 128 patients were expected to be included, and were randomly assigned 1:1 to the combination of metformin and insulin glargine combined with chiglitazar sodium tablet 48mg/ day group. metformin and insulin glargine combined with placebo group.
