NCT04884633

Brief Summary

The investigators propose to conduct a pilot clinical study in 10 type 1 diabetic subjects suffering from hypoglycemia unawareness syndrome and episodes of severe hypoglycemia, in which therapy with transplantation of allogeneic pancreatic islets would be indicated according to current criteria at the Institute for Clinical and Experimental Medicine (IKEM). Pancreatic islets will be isolated and prepared for transplantation using the established laboratory technique with minor modifications corresponding to latest knowledge. In contrast to present routine, the islet preparation will not be administered percutaneously into the portal vein but will be placed on the surface of an omental pouch using a (mini) laparoscopic approach. Cell adherence will be achieved by addition of clinical-grade human thrombin that reacts with plasma to create a biocompatible, degradable gel containing the islet graft. The study will be performed in close collaboration with the Diabetes Research Institute (DRI) in Miami, which will provide expert assistance and technical training if needed.
