Active clinical trials for "Diabetes Mellitus, Type 1"

Randomised prospective single-center clinical trial evaluating the outcomes of children with type 1 diabetes followed up by remote telemedicine check-ups without their personal present at the outpatient clinic.

The objective of the study is to evaluate the feasibility and safety of administering a 4th or 5th intralymphatic booster dose of GAD-alum (Diamyd®) to T1D patients carrying HLA DR3-DQ2, who have earlier been treated with three or four intralymphatic doses of GAD-alum (Diamyd®) respectively.

The transplant of the insulin-producing cell into the liver (Islet transplant) has been proven an effective and valuable treatment for type 1 diabetics patients with poor blood sugar. However, Islet transplant is currently limited by the number of pancreas organ donors and the need for lifelong medication requirements such as antirejection drugs. The investigators have learned that Regulatory T cells (Tregs), a small subset of a cluster of differentiation 4+ (CD4+) T cells, have emerged as the major contributor to self-tolerance by preventing the initiation of unwanted immune activation and by suppressing ongoing immune responses to limit bystander tissue destruction. It has been suggested that infusion of Tregs before extensive graft damage may improve long-term graft outcomes. In this trial, we propose to study Analogous cryopreserved PolyTregs (cePolyTregs). cePolyTregs is a product with the same in vivo functionality to that of the non-cryopreserved PolyTregs.

Can a type 1 diabetic adult avoid low glucoses and regain hypoglycemia awareness using a hybrid closed loop insulin delivery system? Involvement is 22 months (13 visits) and includes a 4-week Screening Phase and an 18-month Intervention Phase. Participants will undergo 3 Hyperinsulinemic Clamps done at: Baseline (before starting the device and after completing the screening), 6 months (after using the device 6 months), and after using the device for 18 months. This metabolic testing will allow us to measure improvement in hypoglycemia awareness.

Current islet transplantation into the portal vein of the liver has shown the unique ability of islets to stabilize blood glucose levels and prevent severe hypoglycemia in a selected group of subjects with Type 1 diabetes. The main limitations of islet transplantation are the need for systemic immunosuppression to maintain function and the loss of islet function over time. Additionally, many studies have demonstrated that the current site of transplantation in the liver is not an ideal site due to several factors. These factors include (1) significant liver inflammation following islet infusion; (2) potential for life-threatening procedure-related complications such as bleeding and thrombosis; (3) high levels of immunosuppressive drugs and GI toxins in the liver contributing to islet toxicity; (4) the inability to retrieve islets after infusion; and (5) development of graft dysfunction in a number of recipients of intrahepatic allogeneic and autologous islets. The implantation of islets into the omentum will allow adequate engraftment of islets onto the omentum and will lead to comparable or superior functional and clinical outcomes than in the traditional intrahepatic site.

The purpose of this study is to study the effect of a liraglutide, a glucagon-like peptide agonist, on post-meal blood glucose concentrations, glucagon levels, mean weekly blood sugars, and insulin doses in adolescents with Type 1 diabetes. Type 1 diabetes is an autoimmune disease that is usually diagnosed before the age of 20. Individuals with this disease are completely dependent on insulin for survival. While significant advances have been made in technological support for improving diabetes control, insulin remains the only effective treatment for Type 1 diabetes. Liraglutide is a long-acting glucagon-like peptide-1 analog. This drug is approved for the treatment of Type 2 diabetes in adults. This study will test the effect of liraglutide on blood sugar control in adolescents with Type 1 diabetes.

In an earlier Phase 1/2 clinical trial using the Edmonton Protocol of steroid free immunosuppression, investigators at University of Illinois at Chicago (UIC) demonstrated the safety of islet preparation, iset transplantation, and medical treatment at UIC. Therefore, the primary purpose of the present Phase 3 clinical trial is to demonstrate the safety and efficacy of allogeneic islet transplantation in improving glycemic control in Type 1 diabetic patients using the UIC protocol that was developed and proven effective during the Phase 1/2 clinical trial.

The purpose of this study is to determine the safety of transplanting human islet cells for controlling hyperglycemia in brittle and/or complex patients with type 1 diabetes. In addition, initial observations will be made with regards to the effectiveness of reversing hypoglycemia with this treatment. The "Edmonton Protocol" of using specific anti-rejection drugs without steroids is also being evaluated.

The primary aim of the study is to evaluate the glucose response to low-dose glucagon (single 150 µg dose) administered immediately before aerobic exercise in individuals with AHCL-treated T1D.

Team Clinic is a new care approach for middle and high school aged patients living with T1D and their families. This study is a 15-month randomized control trial (RCT) that consists of Virtual Team Clinic Care appointments (primarily telemedicine, and in-person as necessary) and Virtual Team Clinic group appointments with a multidisciplinary diabetes care team. Assignment into 1 of 4 intervention groups Team Clinic Care vs. Standard Care which consist of either Virtual Team Clinic Group or no group. Groups: Standard Care - No Group Standard Care - Virtual Team Clinic Group Team Clinic Care - No Group Team Clinic Care - Virtual Team Clinic Group Virtual Team Clinic group sessions will be facilitated by clinical care team (e.g., Registered Dietician, Social Worker, Registered Nurse, etc.) Patients and parents will attend their own online session
