Active clinical trials for "Diabetes Mellitus, Type 1"

This trial is conducted in Europe. The purpose is to evaluate safety and tolerability of a range of single doses of subcutaneous insulin 338.

A recent study suggests that, in Type 1 Diabetes (T1D) patients treated by insulin pumps, a better coordination of meal boluses and post prandial basal rate could reduce the importance of postprandial hyperglycaemias without increasing the risk of delayed hypoglycaemias. The aim of the investigators study is to assess if these results are confirmed in a clinical trial. The aim of this study is to compare the efficacy of coordinated boluses versus normal boluses on postprandial glycaemic control of T1D patients treated with continuous subcutaneous insulin infusion.

This research study examines the effect of hyaluronidase on the length of time of insulin infusion set wear. The aim of the study is to improve the length of time that an infusion set can be worn by infusing hyaluronidase directly into the insulin infusion site.

The purpose of Part I of this study is to evaluate the safety and tolerability of intravenous (IV) doses of MK-2640 in healthy participants and to obtain preliminary plasma pharmacokinetic profiles of MK-2640. The purpose of Parts II and III of this study is to evaluate the safety and tolerability of IV doses of MK-2640 and regular human insulin (RHI), and to evaluate the pharmacokinetic and pharmacodynamic profile of MK-2640 and RHI in participants with type 1 diabetes mellitus (T1DM). Part II will be initiated only if Part I general safety, tolerability and other observed data are supportive of progression to Part II. Part III will be initiated only if Parts I and II general safety, tolerability and other observed data are supportive of progression to Part III.

The study will be conducted in crossover trial, with two 72-hour hospitalization separated by a period Wash-out of at least one week. Each hospitalization is a period of treatment. According to randomization, patients will be provided with either Diabeloop system or the usual system. In both treatment periods: patients in a situation of sedentarity or physical activity, will be equipped with ActiGraph (measuring motricity) and a ActiHeart ( measuring heart rate) meals and physical activities will be similar in both periods the same blood glucose meter will be used throughout the duration of the study. the capillary blood glucose will be performed : before bolus and 2 hours after a meal, before exercise, in case of hypo or hyper-glycemic episodes and when the patient and / or investigator deem it necessary.

This will be a Phase 2b, multicenter, randomized, double blind, titration clinical study, evaluating the efficacy and safety in the HDV Insulin Lispro Group versus Insulin Lispro Group in patients with type 1 diabetes over a 26 week treatment period. The patients will be randomized using a centrally allocated randomization scheme to 1 of the 2 treatment arms in an overall 2:1 scheme (HDV Insulin Lispro: Insulin Lispro). Both arms will receive the randomized treatment in combination with glargine or detemir. Goal to demonstrate that the efficacy of HDV insulin lispro administered in combination with a basal insulin (HDV Insulin Lispro group) is non-inferior to insulin lispro in combination with a basal insulin (Insulin Lispro group), in effects on glycated hemoglobin (HbA1c) in patients with type 1 diabetes. If non-inferiority is demonstrated, confirm that HDV insulin lispro in combination with a basal insulin (HDV Insulin Lispro group) is superior to insulin lispro in combination with a basal insulin (Insulin Lispro group), in effects on HbA1c in patients with type 1 diabetes (≥ 0.4% decrease in HbA1c).

Processed carbohydrates cause rapid changes in blood sugar and have been associated with overeating and obesity. We have shown that test meals high in processed carbohydrate affect brain areas involved in addiction, craving and overeating. It is unknown whether the changes in blood sugar or the associated higher insulin levels mediate this brain activation and its likely adverse effects. Answering this question is important for patients with type 1 diabetes who have elevated risks of obesity and disordered eating: If blood sugar is the causal mechanism, optimal insulin coverage should be protective. If insulin is the causal mechanism, however, a diet high in processed carbohydrate could predispose to overeating and weight gain, as this diet requires higher insulin doses. To disentangle these factors, we will study brain activation and relevant blood markers in 15 men with diabetes. In 4 sessions, we will examine meals with differential carbohydrate properties while giving insulin infusions.

In previous studies, investigators have studied if a pre-meal insulin bolus based on estimated carbohydrate meal size would alleviate the burden of carbohydrate counting without a significant degradation in postprandial glucose control. With this strategy, the patient would only have to evaluate the size of the meal in terms of carbohydrate (snack, regular, large or very large). It is however important to establish the safety of this simplified meal bolus approach. The safety of overestimating a meal insulin bolus in the context of closed-loop strategy needs to be assessed. For ethical reasons, only dual-hormone closed-loop will be tested. Investigators hypothesize that dual-hormone closed-loop with overestimated meal size bolus will not increase time below 4.0 mmol/L compared to dual-hormone closed-loop with an adequately estimated meal size bolus.

The overall aim of this proposed research is to determine the safety, feasibility and efficacy (AP vs at home use of SAP) of the Diabetes Assistant (DiAs) controller in day and night closed-loop control in young children 5-8 years old with type 1 diabetes over multiple 48 hours in an out-patient setting.

Continuous glucose monitoring (CGM) is a tool used in the treatment of patients with type 1 diabetes. A continuous glucose monitor (CGM) is a subcutaneous tissue sensor, which provides a tissue fluid glucose measurement every 1 to 5 minutes. Since CGM measure the glucose level by a sensor in subcutaneous tissue, there is uncertainty in the estimation of blood glucose levels. The accuracy of a certain CGM system can be assessed by comparing the glucose levels estimated by CGM with measured glucose levels in plasma. In the current study, we will compare the accuracy of the 2 CGM systems available on the market for clinical use in patients with type 1 diabetes. The aim of the current study is to evaluate effectiveness, safety and treatment satisfaction with 2 different CGM systems among adult type 1 diabetic patients.
