Active clinical trials for "Diabetes Mellitus, Type 1"

Aim of this study is to verify the effects of an advanced HCL (Medtronic Minimed™ 780G) compared to SAP with PLGS on metabolic outcomes and markers of early microvascular damage in a population of adults with T1D previously treated with CSII. Evaluation of endothelial disfunction and autonomic neuropathy will also be performed.

This proposed study will test whether measurement of breath acetone (BrAce) can be used for the purpose of identifying ketosis (elevated ketones) in persons with type 1 diabetes (T1D). This is important for the potential use of sodium glucose co-transport inhibitors (SGLT2i) in persons with T1D.

Female participants with type 1 diabetes using oral contraceptives will be asked to wear a continuous glucose monitor for at least three days on two separate occasions (once during the last week of active pills and once during the no pill/placebo pill phase of the menstrual cycle). An exercise session (45 minutes of aerobic exercise at 60% VO2peak on a cycle ergometer) will take place at 5 pm on the second day of glucose monitoring.

Participants will be asked to wear a continuous glucose monitor for at least three days on three separate occasions. One testing session will be a no-exercise resting control session (90 minutes). One will be a moderate aerobic exercise session (30 minutes of exercise, 60 minutes of recovery), and the third will be a moderate weight-lifting session (~30 minutes of exercise, 60 minutes of recovery).The investigators will measure changes in blood glucose during exercise by drawing blood during and after exercise. Post-exercise glucose trends will be examined using continuous glucose monitoring.

The study will test an app and web-delivered intervention designed to improve glycemic control (HbA1c) among young adults with Type 1 diabetes. All participants will receive the "core" digital intervention, the SweetGoals app, focused on self-monitoring and goal setting. Efficacy of two independent intervention components (incentives for adherence and web health coaching) will be tested

Almost all people who have had type 1 diabetes for 5 years have a defect in secretion of the hormone Glucagon. This hormone is involved in the body's response to low blood glucose (hypoglycaemia). It works by releasing glucose stores from the liver to bring the blood glucose back to normal. This defect therefore increases the risk of severe hypoglycaemia. The reason for this Glucagon defect in people with Type 1 diabetes is currently unknown. This study aims to look at the Glucagon response to hypoglycaemia in 24 people with type 1 diabetes to ascertain whether tight blood glucose control over a period of time improves this response. The investigators aim to achieve good blood glucose control using new generation Automated Insulin Delivery systems (AIDs). This system is made of: an insulin pump, a continuous glucose monitor (CGM) and an algorithm that allows adjustment of insulin delivery based on the blood glucose readings from the CGM. This is the most up to date technology that there is in the management of type 1 diabetes. However, people using this technology often still have problems with high blood glucose after eating. To ensure a very good blood glucose control participants will also follow a low carbohydrate diet to prevent this blood glucose rise after meals. The Glucagon response to low blood glucose will be measured at zero and eight months using the hyperinsulinaemic hypoglycaemic clamp technique.

This is a prospective, interventional, cohort study, meaning that researchers will follow and observe a group of enrolled study participants over a period of time (one to two months) to gather information and record any developments of the outcomes in question. This study will recruit 125 participants with Type 1 Diabetes (T1D) to: Analyze the effect of reducing the cholesterol levels in the blood on platelet function. (Platelets are small cells in the blood which help form blood clots to slow or stop bleeding and to help wounds heal Analyze the effect of reducing the cholesterol levels in the blood on While Blood Cell (WBC) gene expression, (White Blood Cells are part of the body's immune system which help the body fight infection and other diseases) and Analyze the effect of reducing the cholesterol levels in the blood on vascular or blood vessel function.

The main purpose of this study is to evaluate the safety and tolerability of a study drug called nasal glucagon (Baqsimi) in pediatric participants with type 1 diabetes (T1D) aged 1 to less than 4 years. Blood tests will be performed to check how much nasal glucagon gets into the bloodstream. Blood sugar will also be measured to understand the effect of the drug on blood sugar levels. The study consists of a screening period up to 35 days before dosing, 1 day when a dose of nasal glucagon will be given and then 2 telephone follow up calls; first follow-up call on the day after the nasal glucagon was given and second call about one week after nasal glucagon was given. The study will last up to 9 days, not including the screening period.

Pilot study to evaluate effects of an experimental additional remote digital care (TELEDUC-DIAB) to adolescents with poorly controlled type 1 diabetes using digital monitoring platform and educative app

Despite major technological advances, management of type one diabetes mellitus (T1D) remains suboptimal, putting millions of people at risk for immediate and long-term complications. After meals, a mismatch between carbohydrate absorption rate and insulin action typically leads to alternating periods of hyper- and hypoglycemia. A conceptually promising approach to control both problems is dietary carbohydrate restriction to reduce postprandial blood glucose changes and insulin needs. In a prior survey study, the investigators documented exceptional glycemic control (HbA1c 5.67%) and low acute complication rates among 316 children and adults with T1D consuming a very-low-carbohydrate diet. To test the feasibility of this approach, the investigators will conduct a randomized-controlled feeding study involving 32 adults and adolescents with T1D. Participants will be randomized to receive a very low carbohydrate vs. standard carbohydrate diet. Participants will be in the study for 12 weeks and receive all their meals by meal delivery.They will share continuous glucose monitoring data with the study team and be in close communication to adjust insulin doses as needed. All participants will have a screening visit, an individual or group education session, and 3 study visits to evaluate diabetes control and metabolic health. Some of these visits will have a fasting blood draw. Two of the visits will also comprise additional metabolic studies to assess glucagon response and brain function during hypoglycemia by magnetic resonance imaging (MRI). Participants will have IV catheters placed and receive IV insulin to drop blood glucose levels to 50 mg/dl for up to 30 minutes. The primary outcome will be HbA1c change from baseline. Secondary outcomes include detailed measures of glycemic variability, metabolic health, and quality of life.
