Active clinical trials for "Diabetes Mellitus, Type 1"

Type 1diabetes (T1D) is caused by autoimmune destruction of the pancreatic islet ß-cells, leading to an absolute deficiency in insulin. In health, regulatory T cells (Tregs) suppress immune responses against normal tissues, and likewise prevent autoimmune diseases. Tregs are insufficient in T1D. The investigators previously showed that administration of low doses of IL-2 induces selective expansion and activation of Tregs in mice and humans. The investigators hypothesize that Tregs expansion and activation with low doses of IL2 could block the ongoing autoimmune destruction of insulin producing cells in patients with recently diagnosed T1D.

The purpose of this study is to determine if a small dose of glucagon (mini-dose glucagon) is effective for the treatment of non-severe hypoglycemia in adults with type 1 diabetes (T1D).

Type 1 diabetes mellitus (T1DM) is an autoimmune disease. Based on previous research, study doctors think that giving medicines to affect the immune system soon after diabetes is diagnosed may stop, delay or decrease the destruction of beta cells, resulting in better glucose control. Researchers believe that tocilizumab could have some effect on the cells in the immune system that are thought to be involved in the development of type 1 diabetes. This study will test whether tocilizumab can help preserve or delay destruction of remaining beta cells in people recently diagnosed type 1 diabetes.

Islet transplantation is one of the effective and promising options for type 1 diabetes mellitus treatment1-4. The liver is the primary target location for infusion and portal vein catheterization is generally used. Percutaneous transjugular, percutaneous transhepatic, laparoscopically transmesenteric and laparoscopically transumbilical approaches were often utilized to access the portal. Current islet infusion approach via portal vein of liver has various defects. Percutaneous trans-hepatic puncture is risk of possible severe hemorrhage and portal thrombosis. The laparoscopic entry techniques require longer surgical duration and have an increased rate of catheterization failure. Moreover, the catheters were not allowed to indwell for subsequent infusions. In the current study, the investigators aim to performed open surgery, catheterized the umbilical vein and infused islets into the portal vein. The catheter was indwelled for one month after surgery. Therapeutic effects, surgical parameters and complications were observed to evaluate feasibility and safety.

To evaluate the accuracy of the Flash Glucose Monitoring system (FGM), Abbot FreeStyle Libre, used today in clinical practice in Sweden in estimating plasma glucose levels. Data will be collected in ambulatory patients with type 1 diabetes to determine safety, accuracy, and reliability.

The aim of this extension study is to assess the safety and efficacy of Mylan's insulin glargine and Lantus® in T1DM patients.

The purpose of this pilot study is to evaluate the initial efficacy of a reinforcement intervention to enhance physical activity levels in sedentary adolescents and young adults with type 1 diabetes (T1D). The intervention will reinforce patients for meeting physical activity goals, with escalating reinforcers provided when patients achieve continuous weeks of meeting goals. A 12-week trial will be conducted in which 60 patients will be randomized to: (1) standard care or (2) standard care plus reinforcement.

This is a 2 centres, randomised, double blind, three-treatment, three-period cross-over trial in subjects with type 1 diabetes mellitus. Each subject will be administered individualised single subcutaneous doses of BioChaperone Human Insulin (HinsBet®), insulin lispro (Humalog®) and regular human insulin (Huminsulin® Normal) immediately before ingesting a standardised mixed meal. Following trial drug administration, PK and PD assessments will be carried until 6 hours after start of the standardized test meal. The total trial duration for an individual subject will be up to 11 weeks.

The main objective of this study is to determine whether day and night closed-loop insulin delivery for 4 weeks under free living conditions is superior to usual insulin pump therapy in adults with type 1 diabetes and HbA1C<7.5%. This is an open-label, multi center, randomized, crossover design study, involving a 2-4 week run-in period, followed by two 4 weeks study periods during which glucose levels will be controlled either by an automated day- and night closed-loop system or by subjects usual insulin pump therapy in random order. A total of up to 34 adults (aiming for 24 completed subjects) aged 18 years and older with T1D on insulin pump therapy and HbA1C<7.5% will be recruited through diabetes clinics and other established methods in participating centers. Subjects will receive appropriate training in the safe use of closed-loop insulin delivery system. Subjects will have regular contact with the study team during the home study phase including 24/7 telephone support. The primary outcome is time spent in target range between 3.9 and 10.0 mmol/L as recorded by CGM during home stay. Secondary outcomes are time spent with glucose levels above and below target, as recorded by CGM, and other CGM-based metrics.

Adolescence and young adulthood may be particularly stressful developmental periods due to the numerous transitions into new roles and the need for increased independence. Stress can affect metabolic control in older adolescents and young adults with T1D directly through its impact on cortisol and other hormones that affect insulin metabolism. The proposed study is a pilot randomized clinical trial using a three-group randomized, repeated measures design to assess the efficacy of two treatments (Mindfulness Based Stress Reduction (MBSR) and Cognitive Behavioral Therapy or (CBT) versus an attention control condition for older adolescents and young adults with poorly controlled Type 1 diabetes. As a pilot study, the goal of the research is to test recruitment and retention procedures, finalize intervention measures, training, and fidelity protocols, and estimate effect sizes for a larger clinical trial.
