Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the efficacy of treatment with sitagliptin or dapagliflozin or lobeglitazone in type 2 diabetes mellitus patients, who had inadequate glycemic control even though use of two drug combination therapy with glimepiride and metformin.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Dual combination therapy with metformin and sulphonylurea is the most commonly used combination regimen to treat patients with type 2 diabetes. But, treatment with the dual combination therapy is often unsuccessful at achieving glycaemic control in patients with type 2 diabetes.

Recently, various oral hypoglycemic agents were developed including dipeptidyl peptidase (DPP)-IV inhibitor, sodium-glucose cotransporter 2 (SGLT2) inhibitor and new peroxisome proliferator-activated receptors (PPARs) agonists.

But, there have been few studies about the glucose lowering effect of these drugs in Type 2 diabetes patients on the dual combination therapy with a sulfonylurea agent and metformin.

Hence, the researchers plan to investigate the efficacy and safety of these drugs in combination with a sulfonylurea agent and metformin in type 2 diabetic patients.
