Filter by:This global study (US, Canada, and Australia) will evaluate the safety and effectiveness of the MiniMed 780G system in type 1 adult and pediatric subjects utilizing Fiasp (insulin aspart injection) in a home setting.
A closed-loop insulin system, also referred to as the "artificial pancreas" (AP), is made up of an insulin pump, a continuous glucose monitor, and an application communicating between the two to adjust insulin administration based on glucose control. This is meant for the treatment of type 1 diabetes. The McGill Artificial Pancreas (MAP) has been used previously in type 1 diabetes with significant benefits. Though prior studies have shown significant benefit with this system, some challenges still exist. Semaglutide is used in type 2 diabetes and obesity; it is a once-weekly injectable medication that increases levels of a gut hormone called Glucagon-Like Peptide-1, which modifies gastric emptying, suppresses glucagon, and suppresses appetite. Though its use is not approved in type 1 diabetes in North America, it (along with similar drugs) has been used in studies as adjunctive therapy with insulin with benefits on blood sugar control. Similar medications have been used in type 1 diabetes (such as liraglutide and exenatide), but are not as strong in glucose effect even in type 2 diabetes as compared with semaglutide. The purpose of our study is to see if semaglutide administered weekly at the maximum tolerated dose in those with type 1 diabetes will have improved glucose control (as per time in target range from continuous glucose monitoring data) compared to placebo, while using a closed-loop insulin system.
A virtual group of teens with type 1 diabetes, led by young adults with type 1 diabetes, will play active videogames and discuss activity and health. This study will evaluate the program for feasibility and user satisfaction.
The aim of this study is to compare visual-motor integration, academic achievement and participation in activities of daily living with and without type 1 diabetes.
This study will examine the effects a Glucagon Receptor Antagonist (GRA), has on Insulin Sensitivity, Cardiovascular risks (CVD), and Ketone body formation in participants with Type 1 diabetes. The participants will complete blood tests, tests to measure energy expenditure, CVD risks, and insulin resistance. These tests will be performed prior to start of treatment and again after 12-weeks of treatment with the GRA (called REMD-477).
Type 1 diabetes (T1D) results from the killing of insulin-producing pancreatic beta cells by cells of the immune system. The study aims to slow the progressive, immune-mediated loss of insulin-producing beta cells that occurs after clinical presentation. The investigators have identified a pathway that is important for immune cells to kill beta cells, and a drug that will block this pathway and prevent beta cell death. This drug, baricitinib, is already in clinical use for rheumatoid arthritis, and is currently in clinical trials for other diseases, including childhood autoimmune diseases. It is hypothesized that baricitinib treatment for 48 weeks will preserve beta cell function in children and young adults with recently-diagnosed T1D. The trial aims to recruit 83 participants aged 10-30 years who have been recently diagnosed with T1D. Two thirds of the participants will be randomly assigned to receive baricitinib, one third will receive placebo. The trial will test if baricitinib can slow the progressive loss of insulin-producing beta cells in these patients. The primary objective is to determine if baricitinib can reduce the loss of meal-stimulated plasma C-peptide, a measure of beta-cell function. Maintaining endogenous insulin in recent-onset T1D improves glucose control and may lead to long-term improvements in glucose and lower rates of serious diabetes complications and death.
To the investigator's knowledge, there are no data available in the current literature regarding the acute effects of postprandial hyperglycemia and insulin timing on myocardial perfusion in people with type 1 diabetes (T1D). Observational studies using CEU in type 2 diabetes demonstrate that postprandial hyperglycemia determines myocardial perfusion defects. The investigator hypothesizes that the combination of postprandial hyperglycemia and insulin increases pulse wave velocity (i.e., aortic stiffness) and myocardial vasoconstriction, thereby reducing myocardial perfusion in T1D when compared to healthy controls. Furthermore, the investigator hypothesizes in T1D that dosing insulin before meal intake will ameliorate these cardiovascular defects.
To analyze with the aid of CGM the blood sugar profiles of children receiving dual-wave versus standard bolus for dinner.
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.
