Active clinical trials for "Diabetes Mellitus, Type 1"

Type 1 diabetes (T1D) is one of the most common chronic childhood diseases requiring lifelong insulin therapy. Children and adolescents with T1D need regular insulin injections or the continuous insulin delivery using an insulin pump in order to keep blood glucose levels normal. We know that keeping blood sugars in the normal range will help prevent longterm diabetes-related complications involving the eyes, kidneys and heart. However, achieving treatment goals can be very difficult as the tighter we try to control blood glucose levels, the greater the risk to develop symptoms and signs of low glucose levels (hypoglycaemia). This is a particular problem at night and one solution is to develop a system whereby the amount of insulin injected is controlled by a computer and is very closely matched to the blood sugar levels on a continuous basis. This can be achieved by what is known as a "closed-loop system" where a small glucose sensor placed under the skin communicates with a computer containing an algorithm that drives an insulin pump. We have been testing such a system in Cambridge over the last five years in children and have found that this system is effective at maintaining tight glucose control and preventing nocturnal hypoglycaemia. More recently the system has been tested in real life conditions in the home setting for three weeks during a pilot single-centre study. The next step is to extend the evaluation of closed-loop over a prolonged period of three months. In the present study we are planning to study 24 young people aged 6-18 years on insulin pump therapy. During three months glucose will be controlled by the computer and during the other three months the subjects will make their own adjustments to the insulin therapy using real-time continuous glucose monitoring. We aim to determine the effect of the computer algorithm in keeping glucose levels between 3.9 and 8 mmol/L (normal levels). Safety evaluation comprises assessment of the frequency of severe hypoglycaemic episodes. Participants' response to the use of the system in terms of lifestyle change, daily diabetes management and fear of hypoglycaemia will be assessed. We will also test for longer term glucose control by measuring glycated haemoglobin (HbA1c).

6-8% of USA population has diabetes. Intensive blood glucose control dramatically reduces the devastating complications that result from poorly controlled diabetes. However, for many patients, achievement of tight glucose control is difficult with current regimens. Trivalent chromium, the form found in foods and dietary supplements, is believed to be safe. Our preliminary studies have reported that chromium supplementation inhibits the increase in pro-inflammatory cytokines (tumor necrosis factor-alpha and interleukin-6; TNF-alpha and IL-6) secretion levels caused by high glucose levels in cultured monocytic cells. Similarly, animal studies have shown that chromium niacinate supplementation lowered blood levels of glycemia and pro-inflammatory cytokines in streptozotocin-treated diabetic rats. Cytokines are proteins that are secreted by monocytes and other cells in response to various stimuli, such as infection. Some of the cytokines are known to regulate insulin sensitivity and elevated level of these cytokines in blood may accelerate clogging of arteries. Thus, chromium supplementation may increase insulin sensitivity and glycemic control in diabetic patients, and may prevent the development of cardiovascular disease in diabetic patients. Given the enormous public health cost of diabetes, the prospect of being able to use a relatively low-cost dietary supplement, such as chromium, as an adjuvant therapy to help in achieving normal blood glucose level merits further study. We will examine the effects of placebo and chromium niacinate supplementation on the fasting glucose, cholesterol, triglycerides, and markers of vascular disease in blood of diabetic patients. We will determine these above parameters at baseline and after the 1, 2 and 3 months of supplementation in diabetic patients. The long-term objective is to explore the efficacy of chromium as an adjuvant treatment for better glycemic control, prevent the development of cardiovascular disease (CVD), and improve the life expectancy in diabetic population. Chromium supplements are widely used by the public and are available in many stores, such as Wal-mart, Walgreens, and many other food and drug stores. Chromium is an essential trace metal and micronutrient present in wide variety of vegetables. Niacin is a vitamin B6, an essential vitamin for our body. This study plans to use chromium niacinate, a complex of chromium and niacin. Chromium niacinate is considered a nutrient.

This trial is conducted in North America. The aim of this trial is to evaluate the safety of insulin detemir for the treatment of diabetes.

The purpose of this study is to evaluate the safety and efficacy of BIOD-123 compared to insulin lispro (Humalog®) when used as part of a basal-bolus regimen in patients with type 1 diabetes.

This trial is conducted in Africa, Europe and Oceania. The aim of this trial is to investigate whether insulin detemir combined with insulin aspart compared to NPH insulin combined with insulin aspart could reduce the frequency of hypoglycaemic episodes whilst maintaining the same degree of glycaemic control subjects with type 1 diabetes.

Primary Objective: To compare the efficacy of a new formulation of insulin glargine and Lantus in terms of change of HbA1c from baseline to endpoint (scheduled at month 6 [week 26]) in japanese patients with type 1 diabetes mellitus Secondary Objectives: To compare a new formulation of insulin glargine and Lantus in terms of change in fasting plasma glucose (FPG), preinjection plasma glucose, 8-point self-measured plasma glucose (SMPG) profile. To compare a new formulation of insulin glargine and Lantus in terms of occurrence of hypoglycemia

The purpose of this study is to establish the safety and efficacy of xenotransplantation of DIABECELL® in patients with established type 1 diabetes mellitus

This trial is conducted in Europe. The aim of this trial is to evaluate the efficacy and safety of biphasic insulin aspart 30 in subjects with type 1 or type 2 diabetes.

The purpose of this study is to test the safety and effectiveness of two dosage levels (10mg and 20mg) of TZP-102 compared to placebo (capsule that looks like the study drug but contains no active drug), administered once-daily for 12 weeks, in diabetic subjects with symptoms associated with gastroparesis.

The objective is to describe the interaction of equal doses of NPH insulin (Neutral Protamine Hagedorn), insulin Detemir and insulin glargine on IGFBP-1 (Insulin-like Growth Factor Binding Protein-1) production as well as immunoreactive and bioactive IGF-I (Insulin-like Growth Factor-I) after once-daily injection on three separate visits in type 1 diabetic subjects.
