Type 2 diabetes results when the body does not produce enough insulin and/or is unable to properly use the insulin it makes (insulin resistance). This study was undertaken to assess the effects of vildagliptin on insulin sensitivity in people with type 2 diabetes.

Diabetes Mellitus, Type 2
Drug: Vildagliptin
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Pharmacodynamics Study
Intervention Model: Crossover Assignment
Masking: Double-Blind
Primary Purpose: Treatment
Official Title: A Study to Assess the Effects of DPP-4 Inhibition on Insulin Sensitivity in Type 2 Diabetes
