NCT00150410

NCT00287066
To assess the impact of inhalation of insulin on glucose disposition in patients with type 1 diabetes
NCT00315952
University of Pittsburgh Medical Center (UPMC) diabetes research physicians are studying the action in muscle tissue of "inhaled" insulin (Exubera®) and "infused" (intravenous or IV) insulin on blood sugar control in people with type 1 diabetes. Type 1 diabetics often take 2-4 shots of insulin every day. Exubera may offer an alternative to these insulin injections.
NCT00222768
The purpose of this research study is to use a relatively new technology, called Positron Emission Tomography (PET), to study how insulin works on sugar in your body's fatty tissue. PET imaging is a way of obtaining a "metabolic image" of your internal organs. It does not involve surgery and is not a high risk process. It has been used successfully to study brain, heart and more recently, skeletal muscle. In this research study, we will use PET in combination with Magnetic Resonance Imaging (MRI), to study fatty tissues in healthy people who do not have diabetes. In the future, we plan to do similar PET/MRI studies in individuals with type 2 diabetes mellitus (T2DM) and in individuals who are likely to develop T2DM. Fat tissue might have a lot to do with developing type 2 diabetes. First, it is well recognized that excess fatty tissues, especially the kind in your belly, increases risk for the development of T2DM, as well as affecting other ways the body uses insulin. Second, fatty tissue is a classic target tissue for the action of insulin, which regulates the use of sugar by fat cells and also regulates the release of fatty acids from fatty tissues. Third, studies in mice that lack fatty tissue, indicate that severe insulin resistance (lack of a normal response to insulin) can result. Other types of studies have shown that fatty tissues make proteins that affect your body's insulin and your appetite in good and bad ways. Yet despite this importance, we still lack techniques for the study of fatty tissue metabolism in humans.
NCT00243984
The purpose of this study is to evaluate the efficacy of topiramate compared to placebo in the treatment of obesity in metabolic syndrome. Secondary objectives include topiramate and weight loss effects on lipid levels, HbA1C, insulin resistance, and blood pressure.
NCT00424411
To determine, in subjects with Type 2 Diabetes Mellitus: 1. Whether glycemic control can be achieved at least as effectively with an insulin regimen involving pre-meal EXUBERA™ (inhaled insulin) plus a single bedtime Ultralente injection as with a conventional subcutaneous insulin regimen involving 2 mixed Regular/NPH insulin injections per day. 2. The toleration and safety of EXUBERA™ (inhaled insulin) therapy and its effects after 6 months, if any, on measures of pulmonary function.
NCT00110864
This study is designed to evaluate the safety and efficacy of PN2034 in insulin-dependent type 2 diabetics as measured by the change in average daily insulin dose from baseline to week 12. The effects of PN2034 on HbA1c, fasting plasma glucose (FPG), and lipid levels will also be measured.
NCT00134147
To assess the impact on glucose control by inhaled insulin in patients with type 2 diabetes who are not well controlled on 2 or more oral anti-diabetic agents
NCT00252876
This is a 107-week open-label, multi-center long-term extension study from GALLANT studies 2/22, 5, 7, 8 and 14 to monitor the safety and tolerability of oral tesaglitazar 1 mg in patients with type 2 diabetes during up to 104 weeks of treatment. The total duration, including treatment and follow-up, is 107 weeks.
NCT00139763
This is a questionnaire based study (no study drug is involved) that asks if more patients with uncontrolled type 2 diabetes on diabetes pills will choose insulin as the next treatment choice if inhaled insulin were available in addition to all currently available treatments, compared with if inhaled insulin was not available as part of currently available treatments. This study will also ask if patients with uncontrolled type 2 diabetes currently managed on diabetes pills + once daily insulin will choose as the next treatment choice to take insulin multiple times a day if inhaled insulin were available in addition to all currently available treatments, compared with if inhaled insulin was not available as part of currently available treatments.
NCT00169832
HYPOTHESES * Rosiglitazone in diabetic patients with previous coronary bypass surgery may prevent or slow the progression of atherosclerosis in SVGs and native coronary arteries. * Rosiglitazone has favorable effects on adipose tissue distribution variables as well as on thrombosis, pro-inflammatory, and lipid profiles in diabetic patients after coronary bypass artery surgery. * Rosiglitazone therapy influences favorably metabolism and clinical outcomes in diabetic patients after coronary artery bypass surgery. OBJECTIVES * PRIMARY To assess the efficacy of rosiglitazone to reduce atherosclerosis progression in vein grafts in diabetic patients after coronary bypass surgery by using IVUS imaging after a 12 mo follow-up. * SECONDARY * To prospectively compare the secondary IVUS endpoints. * To prospectively compare the angiographic endpoints. * To prospectively compare the metabolic risk factor endpoints. * To prospectively compare the body composition and distribution endpoints. * To prospectively compare the clinical outcomes of rosiglitazone versus standard care using composite endpoints.
NCT00065312
The purpose of this study is to determine if an investigational drug is safe and efficacious for poorly controlled type 2 diabetes mellitus.
NCT00540488
To measure and compare the glycemic and insulinemic responses of subjects consuming a standard and two diabetes-specific products.
NCT00160160
This study is to demonstrate the superiority of combination of eprosartan/HCTZ versus ramipril/HCTZ.
NCT00494663
DiObex Inc. is developing an experimental drug (DIO-902) that is made up of part of the ketoconazole molecule for the treatment of elevated blood glucose associated with type 2 diabetes mellitus. Ketoconazole (Nizoral®) is a drug available by prescription for the treatment of fungal infections however DIO-902 is an investigational drug. DIO-902 may lower blood glucose by lowering levels of a naturally occurring hormone called cortisol. Elevated cortisol may contribute to the development of type 2 diabetes. The purpose of this research study is to test the safety of DIO-902 when taken by mouth with metformin and the cholesterol-lowering drug atorvastatin to determine the type and severity of any side effects from this treatment. Other purposes of the study are to see how the treatment affects your blood glucose levels, cholesterol levels, blood pressure, and waist circumference.

NCT00255541
This is a 52-week randomized, double-blind, parallel-group, multi-center, active-controlled (glibenclamide) study of tesaglitazar in patients with type 2 diabetes, not adequately controlled on diet and lifestyle advice alone during the run-in period. The study comprises a 6 week placebo single blind run in period followed by a 52-week double blind treatment period and a 3-week follow-up period. Tesaglitazar and glibenclamide will be titrated to optimal effect or highest tolerable dose during the first 12 weeks.
