E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
In patients who are 8805;30 and 8804;65 years of age with type 2 diabetes mellitus T2DM who have inadequate glycemic control FPG 8805;130 7.2mmol/l and 8804;260 mg/dL 14.4 mmol/L 2.1.1 Primary Objective After 6 weeks, to assess the effect of treatment of sitagliptin compared with placebo on incremental glucose area under the curve. Hypothesis After 6 weeks, treatment with sitagliptin compared with placebo provides greater improvement in incremental glucose area under the curve. Objective To assess the safety and tolerability of sitagliptin. Hypothesis Sitagliptin is well tolerated |
|
E.2.2 | Secondary objectives of the trial |
Objective After 6 weeks, to examine the effect of treatment with sitagliptin compared with placebo on 1. Parameters of model assessment of 946;-cell function a. 946;-cell glucose sensitivity b. Rate sensitivity c. Potentiation factor 2. Incretin response for insulin. 3. Plasma glucagon response after a meal challenge. 4. Endogenous glucose production. 5. Incretin response for glucagon. 6. Glucose clearance. 7. Appearance of exogenous glucose. 8. The post-meal triglyceride excursion. 9. The post-meal Non-esterified Free Fatty Acids.Objective To examine incretin function in T2DM compared with normal glucose tolerant subjects under physiological conditions by quantifying the incretin contribution to overall 946;-cell function. |
