Islet + Parathyroid Co-transplant for Type 1 Diabetes
(PARADIGM Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
The primary objective is to test the hypothesis that co-transplantation of allogeneic PTG with adult pancreatic islets (derived from same deceased donor) in the IM site in people with Type 1 diabetes with functioning kidney and/or liver transplants is safe, allows islet engraftment, and leads to insulin independence.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, if you are taking a calcineurin inhibitor-based maintenance immunosuppression, you must continue it. Please consult with the trial team for more details.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, it mentions that participants should be on certain immunosuppressive medications if they have had a kidney or liver transplant. It's best to discuss your specific medications with the trial team.
What safety data exists for islet and parathyroid co-transplantation in Type 1 Diabetes?
The safety data for islet transplantation, which is a component of the islet and parathyroid co-transplantation, indicates that it is a minimally invasive procedure with some risks associated with immunosuppression, such as infections and malignancies. A study involving autologous regulatory T cells in islet transplantation showed no negative effects related to Treg infusion and only minor complications from immunosuppressive drugs, suggesting that the treatment is safe and feasible. However, there is no specific safety data available for the co-transplantation of islet and parathyroid glands.12345
Is the Islet + Parathyroid Co-transplant for Type 1 Diabetes safe for humans?
Research on pancreatic islet transplantation, which is part of the Islet + Parathyroid Co-transplant, shows that it is generally safe, though it requires ongoing medication to prevent the body from rejecting the transplant. Some studies have shown minor complications related to these medications, but no major safety concerns have been reported.12345
Is the treatment of co-transplanting parathyroid glands with pancreatic islets promising for type 1 diabetes?
Yes, co-transplanting parathyroid glands with pancreatic islets is promising because it can improve the success of islet transplants. This approach may help the transplanted cells survive better and work more effectively, potentially leading to better blood sugar control for people with type 1 diabetes.678910
How is the Islet + Parathyroid Co-transplant treatment different from other treatments for type 1 diabetes?
The Islet + Parathyroid Co-transplant treatment is unique because it combines pancreatic islets with parathyroid tissue, potentially enhancing the survival and function of the transplanted islets, which are responsible for insulin production. This approach aims to improve the engraftment and effectiveness of islet transplants, which traditionally face challenges like immune rejection and limited donor availability.678910
What data supports the idea that Islet + Parathyroid Co-transplant for Type 1 Diabetes is an effective treatment?
The available research shows that while islet transplantation has improved over time, it still faces challenges like the need for multiple donor organs and difficulties in monitoring success. Pancreas transplantation is often more successful, especially for patients with low surgical risk. However, islet transplantation is a better option for those with high surgical risk due to other health issues. Both treatments can prevent severe low blood sugar in the long term, which is a significant benefit for people with type 1 diabetes. The 'Edmonton Protocol' improved short-term outcomes for islet transplants, but long-term insulin independence remains low, indicating room for improvement.56111213
What data supports the effectiveness of the treatment Co-transplantation of PTG with Pancreatic Islets for Type 1 Diabetes?
Pancreatic islet transplantation has shown promise in improving blood sugar control in type 1 diabetes, although achieving long-term insulin independence remains challenging. The Edmonton Protocol improved short-term outcomes, but further advances are needed to maintain the function of transplanted islets over time.56111213
