Active clinical trials for "Diabetes Mellitus, Type 2"

A multi-center, randomized, parallel, interventional, open label trial to compare Hemoglobin A1C-lowering effect of conventional treatment and Smart Care Service in patients with type 2 diabetes.

Diabetes and high blood pressure are risk factors for developing heart disease. An increase in the number of diabetes patients is expected. This increases the number of patients with heart disease, and since the vast majority with diabetes die from heart disease, it is extremely important to investigate how these diseases can be prevented and treated. Studies in animals have shown that intestinal hormone glucagon-like peptide-1 (GLP-1) can expand blood vessels, thus lowering blood pressure, but it is not known whether the effects is found in humans, which we will investigate. Studies have also shown that GLP-1 lowers blood sugar, but it is unclear whether this is solely due to increased insulin production, weight loss associated with GLP-1 intake or GLP-1 has an effect on the muscles which increases the uptake of sugar. We investigate whether GLP-1 enhances the absorption of sugar in the leg. The investigators also examines whether these effects are greater in people with diabetes then in healthy.

Response to treatment in Type 2 Diabetes is highly variable; the same medicine may have little effect in one person but a large effect in another. Understanding mechanisms of altered response to treatment could aid treatment selection and assist the design of new medications with lower nonresponse rates. This study will examine the physiological mechanisms and potential clinical/biomarker predictors of altered response to sulphonylurea and DPPIV inhibitor glucose lowering medication and answer fundamental methodological questions for the future study of variation in treatment response in Type 2 Diabetes. Participants will withdraw sulphonylurea therapy for up to 2 weeks with assessment of baseline characteristics and glycaemic response. Participants will then enter an optional extension where they receive sulphonylurea or DPPIV inhibitor therapy in crossover fashion.

Management of type 2 diabetes is an ongoing challenge for patients and their doctors. In order to prevent complications, patients need to monitor and control their blood sugar levels. In addition, they may need to have an ongoing communication with their doctor in order to modify treatment. In this study the investigators wish to compare the benefits of continuous glucose monitoring system (CGMS) to an internet-based glucose monitoring system (IBGMS). The investigators also want to determine whether the frequency of blood glucose testing affects blood glucose control and to see whether the benefits of CGMS and IBGMS are independent of testing frequency.

This is a biomarker exploratory study which is designed to investigate the function and oxidation of the high density lipoprotein (HDL) (the good cholesterol) in patients with type 2 diabetes mellitus treated with Vitamin E versus placebo and segregated by the type of the Haptoglobin protein they have in their blood.

Our goal is to determine the acute effects of intranasal insulin on regional perfusion and cognition of older adults. We propose a pilot study to examine the effect of a single dose of intranasal insulin on regional vasoreactivity and cognitive functions in 30 subjects with T2DM and 30 healthy controls >50 years old using a double blinded, placebo-controlled, cross-over design. Hypothesis 1: Intranasal insulin improves acutely regional perfusion and vasoreactivity in older patients with T2DM as compared with placebo and compared with the control group. Hypothesis 2: Intranasal insulin improves cognitive functioning including attention, memory and executive function in diabetic patients as compared with placebo and compared with control group.

This study is a Phase I, open-label, single-sequence drug interaction study to evaluate the effect of repeated doses of GSK1292263 on the pharmacokinetics of rosuvastatin and simvastatin in healthy adult subjects. Each subject will receive single doses of simvastatin and rosuvastatin on two occasions, once alone and once following administration of repeated (BID) doses of GSK1292263.

The purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of PF-04991532 following multiple (14 days) escalating oral doses in patient wtih type 2 diabetes.

Metabolic defects contributing to the development of type 2 diabetes (T2D) are relative insulin insufficiency and insulin resistance that are associated with a cluster of abnormalities that increase the risk for cardiovascular disease including dyslipidemia, inflammation, hemodynamic changes and endothelial dysfunction. The dyslipidemia associated with T2D is characterized by elevated triglycerides and decreased high-density lipoprotein-cholesterol (HDL). The ability of the insulin sensitizing agent pioglitazone (ACTOS®) , to improve hyperglycemia in subjects with T2D is now well established. Pioglitazone functions as a PPAR-γ (peroxisome proliferator-activated receptor gamma) agonists and this class of drugs have demonstrated several other potential benefits, beyond glucose homeostasis. Specifically pioglitazone can improve diabetic dyslipidemia by increasing HDL cholesterol and lowing triglycerides. A potential beneficial effect on reverse cholesterol transport may be mediated by the increased HDL levels. This proposal aims to examine the effect of PPAR-γ activation by PIO on various aspects of reverse cholesterol transport by testing the hypothesis that PIO treatment affects key steps in the reverse cholesterol transport pathway either directly, through induction of protein expression, or indirectly, by altering HDL structure and composition leading to increase cholesterol flux through this pathway.

The purpose of this research is to study and determine the effects of Aliskiren on blood vessels and blood flow. The primary hypothesis is that Aliskiren will increase endothelial function by 30% or more in comparison to the placebo group.
