Active clinical trials for "Diabetes Mellitus, Type 2"

The purpose of this trial is to study the drug levels and biomarkers in the body and the safety of an investigational drug (GK1-399) in patients with Type 2 diabetes. Patients in the study will receive placebo for 1 week followed by 1 of 4 treatments for 6 weeks. One of the 4 treatments will be placebo, which does not contain an active ingredient. The study participation includes in-patient and out-patient days.

Aging is accompanied by a progressive loss of skeletal muscle mass and strength, leading to the loss of functional capacity and an increased risk of developing chronic metabolic disease. One of these metabolic diseases interacting with muscle mass is Diabetes Mellitus type 2. Diabetes Mellitus type 2 is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. It has become clear that amongst its many actions, insulin is also a vasoactive hormone. Its effect to cause endothelial-nitric oxide dependent vasodilation is physiologic and dose dependent. Recent data suggest that insulin's metabolic and vascular actions are closely linked. This also means that an increase in microvascular perfusion following food intake is more resistant to postprandial insulin release. This physiological process is brought into prominence with increasing age, and even more in type 2 diabetics, and contributes to diminishing glycaemic control. In the present study the investigators will investigate the impact of postprandial insulin release on microvascular recruitment in the oral cavity.

Diet intervention according to the German Diabetes Risk Score in newly diagnosed type 2 diabetes. This study aims to explore the effect of diet lacking red meat, but containing increased fibers and coffee (verum) versus standard recommendation (control) in a multicenter setting.

This study is designed to investigate the effect of treatment with albiglutide on the cardiac repolarization (corrected QT interval) in healthy male and female subjects. Moxifloxacin, a positive control, or moxifloxacin placebo will be given in order to validate the ability of the study to detect a change in the corrected QT interval.

The objective of the study is to know if the R230C and C230C variants of the ATP-binding cassette transporter A1 (ABCA1) gene are associated with a smaller glucose lowering effect compared to the wild type allele (R230R) in patients with type 2 diabetes.

The aims of a concluding 14-year follow-up study are: To investigate what long-term effect the project model for structured, personalized diabetes care has on 1) the patients' mortality and development of diabetic complications, 2) the patients' use of services from the primary and secondary sector, 3) the patients' self-rated health and motivation, and 4) the doctor-patient relationship.

A single centre, open, randomized, placebo controlled, 3 period cross-over study to evaluate the effects of single oral doses of pioglitazone 45mg, rosiglitazone 8mg and placebo on urinary sodium excretion in 12 healthy male volunteers

Incretin hormones are hormones produced by the gut in response to food intake. These hormones help the body to control the metabolism of glucose (sugar). In particular, two incretin hormones (GLP-1 and GIP) cause the pancreas to secrete more insulin in response to high blood glucose levels. This helps the body to metabolize the glucose more effectively, lowering blood sugar levels. GLP-1 and GIP do not work as well in patients with type 2 diabetes (T2DM) as in subjects who do not have diabetes. This study tests whether a medicine called pioglitazone (Actos), which is commonly used to treat T2DM, improves the ability of GIP to increase insulin secretion. To address this question the investigators will recruit patients with T2DM whose diabetes is controlled with either diet and exercise or with metformin (another medicine commonly used to treat T2DM). Subjects will undergo measurement of body fat by DEXA scanning and a series of studies to characterize their metabolism. These studies include an oral glucose tolerance test (a test sometimes used to diagnose diabetes), a mixed-meal challenge (to measure how much GLP-1 and GIP are produced in response to a meal) and measurement of insulin secretion in response to glucose and GIP given through a vein. The investigators will also obtain small samples of fat (from just under the skin of the belly) using a needle to measure levels of the receptor for GIP. Subjects will then be randomly assigned to 12 weeks of treatment with either pioglitazone or matching placebo (an inactive tablet that does not contain medication). The dose of pioglitazone will be increased during the first 4 weeks to the maximum prescribed dose of 45 mg per day. Subjects will be seen every 2-4 weeks during the treatment phase of the study. After 12 weeks of treatment all studies performed at the beginning of the study will be repeated. The pioglitazone treatment will continue until the end of testing, approximately 4 weeks. The results of this study may give us information about why glucose control deteriorates in T2DM. This information might also lead to new ways to prevent or treat T2DM.

The purpose of the study is to investigate some of the mechanisms behind severe insulin resistance and to determine the dose response to insulin in patients with type 2 diabetes mellitus.
