Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to examine whether sitagliptin, an agent which enhances the action of hormones that control the release of insulin and is already in clinical use for type 2 diabetes, might also improve functional exercise capacity. Specific aims: 1\. To test whether sitagliptin will improve functional exercise capacity in persons with type 2 diabetes compared to glimepiride. 1a. The primary outcome will be peak oxygen consumption (VO2peak) and oxygen uptake kinetics (VO2 kinetics). 1b. Secondary outcomes include cardiac function, endothelial function and tissue oxygen saturation (STO2) as well as health-related quality of life. 2\. To evaluate the impact of sitagliptin on muscle mitochondrial function 2a. The primary outcome to address this aim will be 31P measurements (phosphocreatine, free inorganic phosphate, adenosine triphosphate peaks, adenosine diphosphate and pH) Impact: Novel approaches are needed to decrease excess cardiovascular morbidity and mortality in diabetes. Diabetes impairs cardiovascular fitness and thereby mortality. A demonstration that sitagliptin improves cardiovascular fitness, (and possibly mitochondrial function) will provide important new data pertinent to the management of diabetes and pre-diabetes.
