Active clinical trials for "Diabetes Mellitus, Type 1"

The primary objectives of this study are to compare the difference in glycosylated hemoglobin (HbA1c) from baseline to Month 6 using Hylenex recombinant preadministration in continuous subcutaneous insulin infusion (CSII) versus standard CSII and to evaluate the safety of Hylenex recombinant preadministration, including local tolerability, adverse events, and hypo- and hyperglycemia rates.

Insulin resistance (IR) is an important contributor to increased cardiovascular disease risk in type 1 diabetes (T1D). Non-esterified fatty acid elevation is a significant contributor to IR in T1D and may be a target of intervention. The hypothesis of the study is that isolated fatty acid lowering with acipimox will improve insulin action and blood vessel function and have the benefit of reducing mitochondrial oxidant generation and improving mitochondrial function in T1D. Targeting IR through fatty acid lowering is a novel approach to T1D treatment that may significantly improve current management of TID and of cardiovascular disease (CVD) risk in this high risk population.

The purpose of this study is to investigate the effect and safety of liraglutide 1.8 mg once daily compared to placebo for 52 weeks on change in beta-cell function in patients with newly diagnosed type 1 diabetes as an adjunctive therapy to insulin treatment.

The objective of the proposed research is to evaluate the efficacy and safety of the use of metformin in addition to standard insulin therapy in overweight and obese children and adolescents, age 12-<20 years, with type 1 diabetes for at least 1 year. Secondary objectives are to assess the effect of metformin on C-peptide levels, a measure of how much insulin is still being produced by the beta cells of the pancreas, and on vascular dysfunction. In addition, an ancillary study is planned to assess if metformin will improve tissue-specific insulin resistance in type 1 diabetes using a hyperinsulinemic euglycemic clamp.

The MDLAP (MD-Logic Artificial Pancreas)system is as an automatic system to regulate glucose levels by delivery of insulin operable in clinical trial settings. The safety of the system was proved in previous inpatient and outpatient trials in large number of patients. In the current study we aim to optimize post-prandial closed-loop glycemic control by developing an automated MD-bolus calculator and to evaluate its safety and efficacy in controlling postprandial blood glucose when used together with the MD-Logic artificial pancreas system in type 1 diabetes patients. The study will consist of a pilot study with two segments and a main study segment. The aim of each segment is detailed below: Pilot Study - Segment 1 - Hybrid meal bolus ratio The aim of this segment is to evaluate the efficacy and safety of different pre-meal bolus dosing compared to full closed-loop operation with no meal announcement. Pilot Study - Segment 2 - Insulin dosing during meal In this segment we would like to test the optimal distribution of insulin delivery during the meal. Main study - Segment 3 - Automatic bolus calculator In this main segment of the study we will use the results and conclusions from the previous two pilot segments to develop the MD-Bolus Calculator for closed-loop control use. The safety and efficacy of this automated insulin bolus calculator will be tested in a randomized cross-over study that will compare postprandial glycemic control under MDLAP with and without the use of the MD-Bolus Calculator.

This trial is conducted in Europe. The aim of this trial is to investigate the safety, tolerability, pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of insulin degludec (insulin 454), an explorative formulation, not similar to the proposed commerical formulation.

This trial is conducted in Europe. The aim of this trial is to compare the pharmacodynamics (the effect of the investigated drug on the body) and pharmacokinetics (the exposure of the trial drug in the body) of insulin degludec (insulin 454), an explorative formulation, not similar to the proposed commercial formulation, with insulin glargine in subjects with type 1 and type 2 diabetes.

This trial is conducted in Europe. The aim of this trial is to investigate the pharmacodynamic (the effect of the investigated drug on the body) of insulin degludec (insulin 454), an explorative formulation, not similar to the proposed commercial formulation, under single-dose and steady-state conditions in male subjects with type 1 diabetes.

A randomized placebo-controlled clinical trial investigating the effects of Liraglutide as an add-on to intensive insulin therapy in overweight insulin pump treated type 1 diabetes patients in suboptimal glycemic control.

Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings. A dual-hormone closed-loop strategy would regulate glucose levels through the infusion of two hormones: insulin and glucagon. The main objective of this project is to compare the efficacy of single-hormone closed-loop strategy, dual-hormone closed-loop strategy and conventional insulin pump therapy to regulate glucose levels in a 60-hours in non-standardized conditions in adults with type 1 diabetes. The investigators hypothesized that 1) Controlling glucose levels using single- or dual-hormone CLS is feasible in free-living conditions for long period of time (60 hours); 2) Dual-hormone CLS is superior to single-hormone CLS as assessed by reducing time spent in hypoglycemic range; 3) Both single-hormone and dual-hormone CLS are superior to conventional pump therapy.
