Active clinical trials for "Diabetes Mellitus, Type 2"

This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of multiple ascending doses of RO4998452 compared to placebo in patients with type 2 diabetes mellitus. Successive cohorts of patients will be randomized to receive either active drug, at escalating doses, or placebo. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.

This study is being carried out to see if Dapagliflozin in addition to insulin is effective and safe in treating patients with type 2 diabetes when compared to placebo (identical looking inactive treatment) in addition to insulin

This trial is conducted in Asia. The aim of this clinical trial is to investigate the blood sugar lowering effect of repaglinide plus metformin as initial treatment compared to repaglinide alone in Chinese subjects with type 2 diabetes having an HbA1c (glycosylated haemoglobin A1c) over 8.5 % and who never have taken oral sugar-lowering drugs before. The associated unfavourable events including low blood sugar episodes between the two treatments are also compared.

This study assesses the effects of bardoxolone methyl (RTA 402) in patients with type 2 diabetes and chronic kidney disease.

Patients with diabetes have high blood sugar levels (hyperglycemia) because pancreatic beta-cells no longer produce sufficient insulin. Insufficient beta-cell function can be caused by an autoimmune killing of the beta-cells in type 1 diabetes (T1D), or by poorly understood mechanisms in type 2 diabetes (T2D). Glucagon-like peptide-1 (GLP-1) improves function of the insulin-producing beta cells, but GLP-1 has a very short circulating half-life because it is cleaved by the enzyme dipeptidyl peptidase IV (DPP-4). One current treatment being used to improve glycemia control in patients with T2D is sitagliptin, an inhibitor of DPP-4. By inhibiting DPP-4, sitagliptin increases GLP-1 levels, resulting in improved beta cell function. Sitagliptin is now being tested in individuals with new-onset T1D to determine whether it may help to preserve beta cell function. Because T1D is a disease in which the immune system destroys the insulin-producing beta cells in the pancreas, we wish to determine if and how sitagliptin alters immune function. Sitagliptin has been shown by Merck to be safe and effective with no overt immuno-toxicities. However, several lines of evidence suggest that DPP-4 inhibitors such as sitagliptin could be immunomodulatory. This randomized clinical trial will study immune function in healthy volunteers given short-term (4 week) treatment with either sitagliptin or placebo. During the study, we will take blood samples at various time intervals before, during and after treatment. We will compare the immune response with and without sitagliptin treatment using blood samples from healthy individuals. We will measure changes in the magnitude and type of immune responses. The study period is nine weeks. The study s primary outcome will be changes in blood plasma levels of a protein marker associated with decreased inflammation: Transforming Growth Factor Beta 1 (TGF beta 1). In addition, we plan to use these blood samples to measure sitagliptin s effect on expression levels of several cytokines (immune proteins). We will also measure the level of proliferation in stimulated PBMCs (blood immune cells) and gene expression in whole blood after sitagliptin treatment.

Health disparities related to obesity, pre-diabetes and Type 2 diabetes in the United States represent public health concerns. Given the benefit of exercise in disease prevention and management, evidence-based, cost-effective, brief interventions are needed to improve patient outcomes related to Type 2 diabetes and associated conditions. This novel behavioral intervention study connects individuals with resources within their community to affect change in their health and wellness. The aim is to connect disparate individuals to health and wellness resources to prevent the onset of diabetes. This will be accomplished through a collaborative effort with Vanderbilt Diabetes Center, Nashville Metro Parks and Recreation, and the Metro Public Health Department. A time series design will be used to assess the efficacy of physical activity counseling delivered by a health care professional, plus continued contact intervention delivered via a proactive and reactive health promotion counseling hotline that will leverage our partnership with Metro Parks versus counseling advice alone. In order to refine this intervention (Phase II) before it is executed, focus groups will first be conducted in Phase I with members of the target population in order to obtain feedback on the proposed intervention activities and materials. Qualitative findings and feasibility testing will be the basis for modifying the intervention.

This study evaluates exenatide, sitagliptin, and glimepiride for the treatment of high blood sugar in patients with impaired fasting glucose or early type 2 diabetes. The purpose of this study is to determine if exenatide and sitagliptin increase the amount of insulin made by the pancreas compared to glimepiride. It is hypothesized that exenatide or sitagliptin will sustain or increase the amount of insulin made by the pancreas in comparison to glimepiride.

The purpose of this clinical research study is to learn if BMS-512148 (Dapagliflozin) can help reduce the blood sugar levels in subjects with Type 2 Diabetes who are not well controlled on diet and exercise alone. The safety of this treatment will also be studied

Insulin resistance has been implicated as the central pathogenetic feature of cardiovascular risk factor cluster that includes hypertension, impaired glucose tolerance, diabetes, dyslipidemia, and hemostatic disorders. Recent evidence suggests that increased levels of free fatty acids (FFA) in obese subjects is a leading candidate in the pathogenesis of insulin resistance (1-4). In our preliminary studies on the effect of FFA on insulin secretion and action (lipotoxicity), we have observed that the infusion of Intralipid/heparin to increase FFA ~ four-fold-baseline levels for 48 hours results in a significant and reproducible raise in systolic and diastolic blood pressure (BP) in obese African American subjects with and without diabetes. The increase in blood pressure is apparent after 12 hours of infusion, reaching a peak increment of 32 mm Hg in systolic and 14 mm Hg in diastolic pressure at 24 hours. These preliminary findings indicate that, in addition to the well-known effect on insulin resistance, sustained elevation of FFA results in the development of an acute metabolic syndrome.

The purpose of this study is to determine whether the GI Sleeve is safe and effective in treating Type II diabetes patients
