Effects of Sitagliptin on Type 2 Diabetes Mellitus Patients on Treatment With Metformin and Insulin
Overview[ - collapse ][ - ]
Purpose | The purpose of the study is to determine the efficacy and safety of sitaglipin in the treatment of Type 2 diabetes mellitus (T2DM) patients with inadequate glycemic control using metformin and insulin. |

Current Primary Outcome Measures | Reduction in HbA1c from baseline [Time Frame: six months] [Designated as safety issue: No]To confirm the efficacy of metformin+ insulin+ sitagliptin in controlling glycemia with respect to change from baseline in HbA1c after 24 weeks of administration. This will be accomplished by comparing the difference in change from baseline in HbA1c after 24 weeks of administration, compared with metformin+insulin+glimepiride to a non-inferiority limit of 0.3% , and if non-inferiority is proven, to a superiority limit of 0%. |

Brief Summary | The purpose of the study is to determine the efficacy and safety of sitaglipin in the treatment of Type 2 diabetes mellitus (T2DM) patients with inadequate glycemic control using metformin and insulin. |
Detailed Description | DPP-4 inhibitors enhance function of endogenous incretin that helps with glucose homoeostasis. DPP-4 inhibitors have been proved to promote glycemic control without increasing risk of hypoglycemia and weight gain. In addition, they may improve beta-cell function and do not have any known associations with overt cardiovascular or hepatic safety risks. Addition of sitagliptin to treatment of T2DM patients poorly controlled on insulin +/- metformin has been shown to reduce HbA1c while being generally well-tolerated. It could be clinically useful to add sitaglipin to treatment regimen of T2DM patients on stable therapy with insulin & metformin. Apart from glycemic reduction, secondary effects like prevention of weight gain, reduction in insulin dose, improved cardiovascular risk profile, etc. may be expected from addition of sitagliptin to treatment. |
