Islet Transplantation in Type I Diabetic Patients Using the University of Illinois at Chicago (UIC) Protocol

Expanded access to donislecel (allogeneic islets of Langerhans for transplant; IND BB-11807) is for the treatment of brittle T1D. Brittle T1D is a distinct subset of T1D, representing the most severe and difficult to manage manifestation of the disease. Standard therapies (i.e. exogenous insulin injections and insulin pumps) are not sufficient to regulate blood glucose levels for this subset of patients. Thus, the severity of disease and the lack of metabolic control that occur despite intensive insulin therapy in brittle T1D patients defines a patient population whose risk-benefit profile makes them suitable for islet transplantation. Eligible patients may receive one or several allogeneic pancreatic islet transplants. An independent Data Monitoring Committee (DMC), composed of 3 members who have training in medicine and/or organ transplantation, will review eligibility and safety data within 2 weeks after each islet transplantation and every two months thereafter. An independent monitor, who is knowledgeable about Good Clinical Practice (GCP) guidelines and regulations, monitors the study for compliance with 21 CFR and according to ICH GCP Guidelines. The UIC Institutional Review Board (IRB) reviews safety data annually and on occurrence of serious adverse events. The principal investigator also reports serious adverse events to the US Food and Drug Administration (FDA). Success, partial success, and failure criteria will be the same as indicated in the Phase III clinical trial. Patients will be closely monitored post-transplant by the UIC clinical team and/or their primary care physician for safety and efficacy.
