9 Clinical Trials for Various Conditions
HYPOTHESIS: Impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) have distinct pathophysiologic etiologies. Therefore, therapeutic interventions designed to correct the specific underlying pathogenic abnormalities in IGT and IFG will be required to optimally prevent the progressive beta cell failure and development of overt type 2 diabetes.
This research study will examine brain glucose metabolism after an overnight fast to determine the effect of exenatide on brain glucose metabolism and lipid metabolism.
This study will evaluate the effect of ACZ885 on vascular function in patients with documented atherosclerotic disease and T2DM or IGT.
The purpose of the study is to determine whether treatment of children and adolescents with Impaired Glucose Tolerance (IGT) with rosiglitazone will lead to improvements in insulin sensitivity and glucose tolerance.
The primary objectives of the ORIGIN study were: * To determine whether insulin glargine-mediated normoglycemia can reduce cardiovascular morbidity and/or mortality in people at high risk for vascular disease with either Impaired Fasting Glucose (IFG), Impaired Glucose Tolerance (IGT) or early type 2 diabetes; * To determine whether omega-3 fatty acids can reduce cardiovascular mortality in people with IFG, IGT or early type 2 diabetes. The secondary objectives of the insulin glargine study were to determine if insulin glargine-mediated normoglycemia can reduce: * total mortality (all causes); * the risk of diabetic microvascular outcomes; * the rate of progression of IGT or IFG to type 2 diabetes.
Type 2 Diabetes (T2D) in obese youth is often preceded by a prediabetic state called: Impaired Glucose Tolerance (IGT), which is associated with a pre-existing defect in insulin secretion. This study intends to determine if genetic factors are associated with defects in insulin secretion, the incretin system and hepatic insulin resistance in obese adolescents. The long-term goal of this study is to generate information on both the genetics as well as the pathophysiology of Type 2 Diabetes in Youth, which ultimately might guide the investigators towards better preventive and treatment avenues.
Subjects with impaired glucose tolerance will be randomized to either rosiglitazone or placebo for a 18 month period. The study will look at baseline, 12 month and 18 month data for exercise tolerance, coronary artery calcification and diabetes indicators.
The purpose of this study is to assess the safety and effectiveness of vildagliptin, an unapproved drug, compared to placebo in lowering post-meal blood glucose levels in people with pre-diabetes who have high blood sugar levels after meals.
The specific aims for the study will be to determine if aerobic exercise enhances cognition for older adults who are at risk for developing type II diabetes mellitus (T2DM), and to evaluate whether change in insulin sensitivity predicts cognitive performance for subjects randomized to the aerobic exercise group. Sedentary older adults diagnosed with impaired glucose tolerance using an oral glucose tolerance test will participate in a 6-month supervised protocol of either aerobic exercise or stretching. Cognitive testing and blood collection will occur at baseline, and months 3 and 6. Before and after the 6-month intervention, insulin sensitivity, maximum aerobic capacity, and body fat composition and distribution (via CT scan) will be assessed for all subjects. The results of this study may provide support for a relatively simple and inexpensive treatment strategy that specifically targets many of the health factors that directly influence risk of cognitive decline associated with T2DM for older adults.
