Filter by:Saxagliptin is a new investigational medication being developed for treatment of type 2 diabetes. This study is designed to test the efficacy of once daily saxagliptin in renally impaired patients.
In men with type 2 diabetes, low testosterone levels have been associated with insulin resistance, truncal obesity and symptoms such as fatigue and erectile dysfunction. Low testosterone may impair cardiac function and increase cardiovascular risk and cause osteoporosis. The goal of this project is to assess prospectively whether, in men with type 2 diabetes mellitus and low testosterone levels, testosterone replacement improves insulin resistance, body composition, bone density, cardiac function symptoms associated with low testosterone level. The investigators will recruit 140 ambulatory men with type 2 diabetes and a low serum testosterone level (<10 nmol/L) from Austin Health Endocrine clinics, General Practise surgeries, and from the general public by direct consumer advertising via newspaper and other local media. Men will be randomised to either intramuscular testosterone undecanoate (Reandron 1000, Bayer Schering Pharma) or placebo. Men with contraindications to testosterone replacement or to intramuscular injections will be excluded from the study. All men will receive intramuscular testosterone or placebo injections at 0, 6, 18 and 30 weeks (a total of four injections). All 140 study subjects will have a clinical and laboratory assessment at baseline, 18 weeks and at study end (40 weeks). All 140 subjects will also have imaging studies at baseline and at study end (40 weeks). The study protocol is outlined in more detail below: Clinical and laboratory assessment (Baseline and repeated 18 weeks, 40 weeks) A full medical history and physical examination will be performed. Symptoms will be assessed by the following standardised questionnaires: 1) Androgen Deficiency in the Aging Male (ADAM); 2) Aging Male Symptom scale (AMS); 3) International Index of Erectile Dysfunction (IIED); 4) International Prostate Symptom Score (IPSS); 5) SF-36 (all five questionnaires are attached to Module 1). Laboratory studies will consist of blood tests to measure total testosterone, fasting glucose, C-peptide, HBA1c and other routine parameters. Imaging studies (Baseline and repeated at 40 weeks) 1. Body composition and bone mineral density by DEXA 2. Body composition by magnetic resonance imaging 3. Bony micro-architecture by high resolution quantitative computed tomography [HR-pQCT]), 4. Cardiac dimensions and function by transthoracic doppler echocardiography
The incretin effect is attenuated in patients with type 2 diabetes mellitus partly due to impaired potentiation of beta-cell responsiveness to glucose by glucose dependent insulinotropic polypeptide and glucagon-like peptide-1 respectively. The aim of the present study was to investigate whether 4 weeks of near-normalization of blood glucose could improve the insulin responses to GIP and GLP-1 in patients with type 2 diabetes.
Exenatide twice daily has been studied in Japanese type 2 diabetes patients. A once-weekly version of exenatide is currently being evaluated. Study GWBW is the first study of exenatide once weekly in Japanese patients. This study is designed to evaluate safety and tolerability of exenatide once weekly in Japanese patients and determine whether the dose selected for US and European development is appropriate for Japanese patients with Type 2 diabetes.
Pioglitazone and insulin glargine are equally effective in achieving glycemic control in secondary drug failure of type 2 diabetes but the mechanisms of actions are different.
This study examines whether an antioxidant taken orally will improve glucose tolerance and insulin secretion in type 2 diabetic subjects.
This study will look at two FDA approved medications that improve how the pancreas works in patients with Type 2 Diabetes. In order to understand how these medications work in patients with diabetes we must first measure the normal response in healthy volunteers without diabetes. We will be looking at the body's normal physiological response to low blood sugar and whether this will be modified by these medicationsThe hypothesis would be that glimepiride induced insulin secretion will be inhibited by hypoglycemia.
Patients with Type 2 diabetes and severe insulin resistance with very large insulin requirements who have failed all previous insulin regimens using non-concentrated forms of insulin (U100 insulin formulations) will receive 5X concentrated insulin (U500 regular insulin)infused via insulin pump.
The study evaluates if fat accumulates in the pancreas in individuals at risk of developing obesity-related diabetes. It also evaluates if the amount of fat in the pancreas can predict the residual functional capacity of the pancreas (insulin secretion).
High blood glucose levels in surgical patients with diabetes are associated with increased risk of medical complications and death. Improved glucose control with insulin injections may improve clinical outcome and prevent some of the hospital complications. In patients who have undergone surgery, high blood glucose increases the risk of wound infection, kidney failure and death. It is not known; however, what is the best insulin regimen in patients who will undergo surgery. The use of repeated injections of regular insulin is commonly used for glucose control in hospitalized patients with diabetes. Recently, the combination of Lantus® and Apidra® insulins has been shown to improve glucose control with lower rate of hypoglycemia (low blood sugar). We hypothesize that in patients with type 2 diabetes admitted to general surgery wards, treatment with once daily glargine (Lantus) plus supplemental glulisine insulin (Apidra®) will produce better glycemic control and a lower rate of hospital complications than treatment with regular insulin per sliding scale (SSRI). The present study aims to determine which insulin treatment is best for glucose control in hospitalized patients with diabetes. Glargine and glulisine insulins are approved for use in the treatment of patients with diabetes by the FDA. Subjects included in the study will have type 2 diabetes and be admitted to Grady Memorial Hospital, Veterans Administration Medical Center, and Emory University Hospital, Atlanta, Georgia. A total of ~94 patients will be recruited at each institution. A post-hoc cost analysis of hospitalization costs and charges of the Rabbit surgery trial will be completed in order to determine differences in hospitalization cost between basal bolus insulin and SSI regimen.
