This study will determine 1) the safety of AC2993 in patients with type I diabetes; 2) the ability of AC2993 to improve beta cell function; and 3) the effects of immunosuppression on beta cell function. Type I diabetes is an autoimmune disease, in which the immune system attacks the beta cells of the pancreas. These cells produce insulin, which regulates blood sugar. AC2993 may improve the pancreas's ability to produce insulin and help control blood sugar, but it may a...
This is a multicenter, randomized, blinded, placebo-controlled study to assess the effects on glucose control of AC2993 as compared to placebo in patients with type 2 diabetes. Patients will be randomized into one of two AC2993 treatment arms or to placebo treatment and will continue with their required existing diabetes medication (metformin) throughout the study.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body). The investigators propose a double-blind, randomized controlled pilot study comparing the effect of sitagliptin (a novel anti-diabetic drug with beta-cell protective potential) versus placebo, on the...
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by progressive deterioration in the function of the pancreatic beta-cells, which are the cells that produce and secrete insulin (the hormone primarily responsible for the handling of glucose in the body). We propose a double-blind, randomized controlled study comparing the effect of liraglutide (a novel anti-diabetic drug with beta-cell protective potential) versus placebo, on the preservation of beta...
To examine whether temporary immunosuppression with ATG, tacrolimus and MMF allows prolonged survival of beta cell allografts in type 1 diabetic patients with early chronic complications of diabetes.
This multi-center, open-label study is designed to examine the effects on long-term glucose control and safety of AC2993 in patients with type 2 diabetes treated with metformin, sulfonylurea, or metformin and sulfonylurea combination.
Progression of T2DM is widely accepted to be contributed by two main components: beta cell function deterioration where insulin secretion is impaired and insulin resistance where insulin physiological response is reduced. Insulin resistance and beta cell function will be estimated through a mathematical model, homeostasis model assessment. Fasting insulin and C-peptide will be measured using liquid chromatography tandem mass spectrometry. Insulin resistance and beta cell functi...
The purpose of this study is to characterise beta cell function in subjects who despite taking part in a diabetes prevention program (life style intervention with diet and exercise) exhibit impaired glucose tolerance and beta cell dysfunction.
Recent studies show that many Type 1 diabetes patients have remaining endogenous insulin production, albeit at low levels. Finding means to increase this production would be of tremendous interest, since residual C-peptide concentrations >0.1 nmol/l previously have been shown to markedly lower HbA1c, decrease blood glucose fluctuations and diminish the risk of ketoacidosis. It also substantially reduces the risks of severe hypoglycemic events and late complications. Liraglutide...
To evaluate the effect of Gluten Free Diet (GFD) on beta-cell function and glucose metabolism in subjects with one or several islet autoantibodies without and with dysglycemia at baseline. Additionally, all subjects will be given treatment with Vitamin D, omega fatty acids and probiotics. Subjects will be randomized to GFD or normal diet during 18 months. Beta cell function will be evaluated at baseline, and during follow-up by glucose tolerance tests.
A three months, double-blind, randomised, parallel-group study evaluating the efficacy of sitagliptin (Januvia™) versus placebo on beta-cell function in patients with newly detected glucose abnormalities and acute myocardial infarction or unstable angina pectoris. Primary endpoint Improvement in beta-cell function measured by means of the insulinogenic index (ΔI30/ΔG30) obtained from an oral glucose tolerance test (OGTT). Secondary endpoints 1. Improvement of glu...
This study was intended to evaluate the effect of vitamin D supplementation on insulin sensitivity and pancreatic islet beta-cell function. Our hypothesis was that vitamin D supplementation to normal levels in patients with impaired fasting glucose will result in improved insulin sensitivity and improved beta cell function.
Proof of concept, of RYGBP and its capabilities to cure type 2 diabetes (DM 2) and sleep apnea has already been recognized in the reports on weight loss surgery. The investigators project aims to prove that RYGBP also recovers the beta cell function (BCF) Clamp tests, the gold standard for testing IS and BCF, will be performed preoperative and early postoperatively. Aims & methodology: Analysis of the short-term effect of gastric bypass and sleeve gastrectomy on insul...
The purpose of this study is to evaluate the safety and efficacy of a 28-day regimen of exenatide (AC2993), given as a monotherapy to subjects with type 2 diabetes mellitus.
This study aims to study the effects that two standard of care immunosuppression induction regimens have on regulatory T cells (Treg) in live donor renal transplant recipients. Both regimens are currently used in this hospital for early immunosuppression induction but the effects on Treg numbers and function is not well understood and likely will impact long term immune function.
There is a lot of evidence to show that the yeast beta-glucan has immunomodulatory, anti-inflammatory, anti-infective effects.However,few work was done on the relationship between yeast bata-glucan and the immune function of diabetic patients. This is a randomized double-blind trial, aiming to study the effect of yeast beta-glucan on immune system of prediabetic patients. Firstly, the investigators will go into the efficacy of yeast beta-glucan on improving the clinical symptom...
This is prospective cohort study of patients classified by the premedication history of beta-blocker. We aim to evaluate the hemodynamic effect of beta blocker through Swan-Ganz catheter monitoring and arterial pressure waveform analysis during surgery. We also plan to observe the long-term effects of beta blocker on acute renal failure, allograft failure and mortality.
After transplantation, if insufficient immunosuppression is achieved, rejection and graft loss follows. If to much immunosuppression is given, the patient suffers risk for infections and malignancies. Despite careful dosing and monitoring of drug levels, the biological effects of the immunosuppression given is difficult to predict and varies significantly. As a result, the degree of immunosuppression (or immunosuppressive status) remains unknown and clinical problems related to...
Patients with diabetes have high blood sugar levels (hyperglycemia) because pancreatic beta-cells no longer produce sufficient insulin. Insufficient beta-cell function can be caused by an autoimmune killing of the beta-cells in type 1 diabetes (T1D), or by poorly understood mechanisms in type 2 diabetes (T2D). Glucagon-like peptide-1 (GLP-1) improves function of the insulin-producing beta cells, but GLP-1 has a very short circulating half-life because it is cleaved by the enz...
Among adult patients diagnosed with type 2 diabetes, about 6% have autoantibodies directed against the insulin producing beta cells in the pancreas. These patients have a progressive beta cell destruction and most of them will be insulin dependent within 3-5 yrs. Patients with this latent autoimmune diabetes in adults (LADA) have a considerable remaining beta cell mass at diagnosis, and are suitable for evaluating new therapies for autoimmune diabetes Animal studies in diabete...
In order to evaluate the difference in beta cell mass in women with and without a history of gestational diabetes mellitus (GDM), investigators aim to compare quantitative PET imaging of the pancreas between these groups. Investigators propose to measure uptake of 68Ga-NODAGA-exendin-4 in the pancreatic beta cells of these women as a measure for beta cell mass. Furthermore, investigators aim to compare uptake of the radiolabeled tracer to beta cell function measured by laborato...
The aim of this study is to evaluate the effect of the two different beta blockers metoprolol and carvedilol on endothelial function in patients with either type two diabetes or chronic heart failure. Hypothesis: 1* Carvedilol compared to metoprolol has a favourable effect on endothelial function. 2* Carvedilol compared to metoprolol has a favourable effect on insulin stimulated endothelial function. The study is conducted as an open parallel group study. Endothe...
