Summary

This trial involves transplanting insulin-producing cells into patients with Type 1 Diabetes to help them manage their blood sugar levels without needing insulin injections. The trial also tests medications to protect these new cells from the immune system and improve their function and survival. One of these medications has been studied for its potential to improve beta-cell function in long-standing type 1 diabetes.

Who is the study for?
This trial is for adults aged 18-65 with Type 1 Diabetes Mellitus, BMI ≤26, experiencing severe hypoglycemia unawareness or poor diabetes control despite intensive insulin therapy. Candidates must have had diabetes for over 5 years and show progressive complications. Excluded are those with certain blood markers, untreated eye issues, kidney dysfunction, high insulin requirements or lipid levels, specific infections including HIV/HCV/EBV, history of malignancy (except some skin cancers), unstable heart conditions, pregnancy/breastfeeding without proper contraception use, recent substance abuse/smoking.
What is being tested?
The study tests whether transplanting islet cells can reverse the need for insulin in Type 1 Diabetes patients while avoiding steroid-based immunosuppression. It also examines if this procedure prevents severe low blood sugar episodes and improves long-term health outcomes related to diabetes complications. The effects of infliximab and etanercept on early islet survival and exenatide on graft function/survival are being studied as well.
What are the potential side effects?
Potential side effects may include immune system reactions due to the transplanted cells or medications like infliximab and etanercept used to prevent rejection; these could lead to inflammation or infection risks. Exenatide might cause digestive issues such as nausea or decreased appetite.

Other Research
Common treatments for diabetes include insulin therapy, immunosuppressive therapies, and islet cell transplantation. Insulin therapy involves administering insulin to manage blood glucose levels, crucial for patients whose bodies do not produce enough insulin. Immunosuppressive therapies, such as those used in islet cell transplantation, help prevent the immune system from attacking transplanted islet cells, which are introduced to restore insulin production. Islet cell transplantation specifically aims to replace damaged pancreatic cells with functional ones, potentially reducing or eliminating the need for exogenous insulin. These treatments are vital as they help maintain blood glucose control, reduce complications, and improve the quality of life for diabetes patients.
