Active clinical trials for "Diabetes Mellitus, Type 2"

The study is being undertaken to understand how a gastric bypass can affect a subject's diabetes even prior to their losing significant amounts of weight. The hypothesis of this study is that increased glucagon-like peptide-1 (GLP-1) secretion explains the amelioration in insulin secretion after Roux-en-Y Gastric Bypass (RYGB) surgery.

The purpose of this survey is to examine the safety and efficacy of long-term use of alogliptin/pioglitazone(Liovel) combination tablets in patients with type 2 diabetes mellitus determined as warranting combination therapy with alogliptin benzoate and pioglitazone hydrochloride

Objectives: To quantify differences in control of glycemia (primary objective) and the secretion of endogenous incretin hormones (secondary objective) comparing sitagliptin or placebo added to pre-existing therapy with liraglutide and metformin

To investigate the safety and efficacy of long-term treatment with pioglitazone (Actos tablets) in combination with biguanides (for 12 months after the start of pioglitazone tablets treatment) in patients with type 2 diabetes mellitus.

The purpose of this study is to examine the safety and efficacy of long-term treatment with alogliptin (Nesina) in patients with mild type 2 diabetes mellitus in the routine clinical setting.

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.

The purpose of this study is to determine the safety and efficacy of long-term treatment with alogliptin (Nesina) in patients with type 2 diabetes mellitus who responded inadequately to diet therapy and exercise therapy alone, or a combination of diet therapy, exercise therapy, and α-glucosidase inhibitor. In addition, examining the safety and efficacy of alogliptin in patients with renal impairment, information on the appropriate dosage of alogliptin according to the severity of impaired renal function should be collected.

The purpose of this study is to determine the safety and efficacy of long-term combination therapy with alogliptin (Nesina) and thiazolidinediones in patients with type 2 diabetes mellitus who failed to respond adequately to treatment with thiazolidinediones in addition to diet therapy and exercise therapy.

The present project is designed to test the hypothesis that arginase contributes to endothelial dysfunction induced by ischemia-reperfusion in patients with coronary artery disease.

We want to investigate how lack of glucagon suppression during an oral glucose tolerance test in patients with type 2 diabetes contributes to patients postprandial hyperglycemia.
