Active clinical trials for "Diabetes Mellitus, Type 2"

The planned HERMES study is to investigate and compare the effects of Insulin Glulisine, Insulin Aspart and regular human insulin on postprandial nitrotyrosine concentrations and several clinical and laboratory markers of postprandial endothelial cell function, sub-clinical inflammation and cardiovascular risk in patients with type 2 DM. The primary parameter in this study are the postprandial changes in the nitrotyrosine concentrations, a biomarker for oxidative stress. As vascular data on Insulin Glulisine vs. Insulin Aspart are missing, it is not possible to calculate sample size and statistical power. Therefore the goal of the HERMES-Pilot-Study is to generate preliminary data for statistical considerations and estimations on the probability of success of HERMES.

It is well known that Long-term hyperglycemia (also known as glucose toxicity) contribute to impairment in islet β-cell function and development of insulin resistance. A growing body of evidence also indicates that this impairment inβ-cell function and insulin action could be restored after hyperglycemia is corrected by short-term intensive insulin therapy. In this study, we are determined to use the golden standard of insulin sensitivity evaluation in vivo-hyperinsulinemia euglycemic glucose clamp-to estimate insulin resistance improvement in patients before and after intensive insulin therapy, investigate first phase insulin secretion to evaluate β-cell function, examine the changes in insulin resistance and insulin secretion resulting from normalization of plasma glucose levels in both lean and obese patients by insulin pump therapy.

This protocol is being conducted to determine the mechanisms responsible for insulin resistance, obesity and type 2 diabetes.

The purpose of the study is to evaluate the efficacy and safety of ketogenic diet (KD) treatment of (i) obesity, (ii) type 2 diabetes mellitus and (iii) obstructive sleep apnea (OSA) in patients with obesity and Type 2 DM and in patients with obesity and/or OSA. This will be a randomized, open-label three arm controlled study comparing weight loss in obese participants with type 2 diabetes and/or obstructive sleep apnea treated for 9 months with 3:1 [fat]:[protein+carbohydrate] ratio, 1600 kcal/day diet (Group A) with weight loss in participants treated with orlistat 120 mg TID and lifestyle intervention consisting of dietary advice, recommended caloric goal of 1600 kcal/day (Group B), and in participants treated with only lifestyle intervention consisting of dietary advice, recommended caloric goal of 1600 kcal/day (Group C).

Study to evaluate the efficacy of gastric stimulation (GCM) using the DIAMOND System in the improvement of glycemic control measured by changes in HbA1c. Relationship between blood TG level and the GCM efficacy will be evaluated.

The effect of roux-en-Y gastric bypass(RYGB) on patients with type 2 diabetes mellitus(T2DM) and a body mass index(BMI)>35kg/m2 is clear. There are large-scale patients with T2DM in Chinese population and currently about two-thirds of them are lack of adequate blood glucose control. Asian Chinese have different type of obesity, different style of diet, and a relatively low BMI levels as well. We assess the feasibility and efficacy of laparoscopic roux-en-Y gastric bypass surgery (LRYGB) in patients with non-severely obese T2DM.Taking into account the differences of body size and diet between the United States & Europe and Asian countries, diabetic situation has its special features in different regions, especially in Asia China. Asian Chinese have a high incidence of T2DM and a relatively low BMI levels. Evaluating the benefits from LRYGB for T2DM in Asian Chinese diabetes subjects with a body mass index of less than 35kg/m2 and looking for sufficient evidence to this operation become necessary.The patients will be followed up for one year after surgery and a comparison would be made between the two groups. Clinical indicators that reflect the effect of LRYGB are monitored before surgery and 1, 3,6,12 months after surgery. Complete remission of diabetes was defined by hemoglobin A1c (HbA1c)<6.0% and Fasting plasma glucose (FPG)<5.6mmol/L.

The goal of this study is to build a mathematical model to explain the effect of two doses of azilsartan (40 and 80 mg) upon metabolic (insulin resistance, glucose) and inflammatory parameters (cytokines) in function of "metabolic strata" like obesity, type 2 diabetes mellitus, hypertension and their combinations.

The purpose of this study is to determine whether a non-hematopoietic erythropoietin analogue, ARA 290, exerts beneficial effects on blood glucose levels and insulin secretion in persons with prediabetes (impaired glucose tolerance, IGT, or impaired fasting glucose, IFG), or drug-naive type 2 diabetes. The study will also evaluate effects of ARA 290 on insulin sensitivity and serum levels of inflammatory agents, e.g. cytokines. In addition, safety will be monitored by following parameters related to hematology, kidney and liver function and lipid levels.

This post marketing surveillance study aims to monitor the safety and efficacy of ONGLYZA under conditions of actual use in patients who are diagnosed with diabetes mellitus type 2 and are prescribed ONGLYZA by their physician.

Type 2 diabetes mellitus is a chronic metabolic disorder which is caused by both insulin secretion deficiency and insulin action defect. In this type of subjects, fasting hyperglycemia is the result of the elevated rate of basal hepatic glucose production, and it is coexisting with hyperinsulinemia.After a meal, the impaired control of hepatic glucose production by insulin and decreased insulin-mediated glucose uptake by muscle contributed nearly equally to postprandial hyperglycemia(Scheen, 1997). Type 2 diabetic subjects experience significant morbidity and mortality from microvascular (retinopathy, nephropathy, and neuropathy) and macrovascular (cardiovascular disease, stroke, and peripheral vascular disease) complications. The appropriate treatment and good glycemic control of diabetes is therefore important and necessary (Vaag, 2006). Evidences suggest that combination therapy using oral antidiabetic agents with different mechanisms of action may be more effective in achieving and maintaining target blood glucose level (Turner et al., 2005).There are five classes of oral antihyperglycemic agents (sulfonylureas, biguanides, α- ucosidase inhibitors, thiazolidinediones and meglitinides) currently available to improve glycemic control in subjects with type 2 diabetes, each of which works through a different mechanism of action. Metformin, a biguanide which has insulin-sensitizing properties, can be used alone or in combination with other classes of agents. Metformin is the currently the first-choice treatment in subjects with diagnosed type 2 diabetic subjects and obesity, characterized by insulin-resistance. Metformin also provides reduction of body weight and ameliorates lipid abnormalities and is thought to be related to a reduction in hepatic gluconeogenesis (Hundal & Inzucchi, 2003).Acarbose, the α-glucosidase inhibitor, is approved for the treatment of type 2 diabetes, and first approved for prediabetes treatment (Chiasson et al., 1994; Breuer, 2003; Chiasson et al., 2002). The drug was launched worldwide as a type 2 diabetes monotherapy and combination therapy in 1990 which has proven efficacious as first-line therapy (Coniff et al., 1995) and in combination with sulfonylureas or insulin (Kelley et al., 1998). Acarbose and metformin are both associated with beneficial effects on hyperglycemia, hyperinsulinemia, body weight, and, in some studies,triglyceride levels (Krentz et al., 1994). Because these factors are part of a cluster of risk factors for cardiovascular disease, combining the two drugs may be useful. In long-term clinical studies, acarbose has shown a favorable safety profile (Hasche et al., 1999).In combination with metformin, acarbose has been shown to improve long-term glycemic control (Rosenstock et al., 1998; Halimi et al., 2000). This study was conducted as a further vestigation into the efficacy and safety of concurrent use of acarbose and metformin in type 2 diabetes mellitus subjects.Lotus Pharmaceutical Co., Ltd. intends to initiate Phase III program to investigate assess the efficacy and safety of metformin in combination with acarbose for type 2 diabetes mellitus subjects considered inadequately blood glucose control. Since combination tablet of acarbose and metformin has not yet been approved by the Taiwan DOH, this study is conducted to evaluate the efficacy and safety of combination tablet of acarbose and metformin in the treatment of type 2 diabetes mellitus subjects in Taiwan. Acarbose is chosen as an active-comparator.
