About this study
The primary purpose of this study is to demonstrate the safety of allogeneic islet transplantation in type 1 diabetic patients performed at the University of Illinois at Chicago (UIC). The purpose is to reproduce the Edmonton protocol to demonstrate that pancreatic islets isolated at UIC are safe and of sufficient quality to provide reproducible graft function.
Read the detailed description
Diabetes mellitus is becoming an unbearable burden for the health care system worldwide. The incidence of disease has increased over the past 50 years, both for type I and type II diabetes. In 2002, the expenditure for direct and indirect costs of diabetes reached the astronomical amount of $132 billion for the USA alone. The burden suffered by patients is also grave when we consider that diabetic neuropathy and retinopathy are now the leading causes of renal failure and blindness in industrialized countries. Although major improvements in insulin treatment and glycemic control have been achieved, the development of hypoglycemic unawareness still represents a challenging clinical problem in the management of diabetes. Severe hypoglycemic episodes are not only acutely life threatening but lead to overall impairment of the quality of life of diabetic patients. Even under ideal study conditions the pathophysiology of hypoglycemic unawareness is not fully understood. It seems that each hypoglycemic episode reduces the counterregulatory hormone responses and the subjective awareness of the following episode, generating a self-worsening mechanism. Islet transplantation can effectively eliminate severe hypoglycemia and restore good glycemic control. However, there are still several limitations to the widespread application of islet transplantation. First, insulin independence is mostly achieved by transplanting a high number of islets that are harvested from 2-4 donors. Second, post-transplant insulin-independence is progressively lost over time despite continued endogenous insulin secretion. Lastly, current immunosuppression carries potential risks and can only incompletely prevent sensitization of the host and rejection.
At present, clinical trials in islet transplantation face stringent federal regulations, which define islets as a biological drug and islet transplantation as an experimental procedure. Limited resources impose small and uncontrolled trials investigating a limited number of new interventions to improve outcomes.
This study is a Phase 1/2 single center, uncontrolled trial in which 1-3 allogeneic pancreatic islet transplants are performed for each study subject. Post-transplant follow-up continues for 64 weeks after the final islet transplantation. Thereafter, subjects are enrolled for a 5-year follow-up study and a 5 to 10 year follow-up study.
The safety of islet transplantation depends primarily on the incidence of serious and unexpected complications or adverse events and the ability of the cell isolation laboratory to produce uncontaminated islet cell preparations with minimal endotoxin content. All study subjects are followed for safety for one year. 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 approximately 2 weeks after each islet transplantation and every two months thereafter. An independent monitor knowledge on Good Clinical Practice(GCP) guidelines and regulations monitors the study for compliance with 21 CFR and according to ICH GCP Guidelines. Within the Clinical Research Center, the Scientific Advisory Committee and the Research Subject Advocacy Program monitor safety. These entities report to the Institutional Review Board, which also reviews safety data annually and on occurrence of serious adverse events. The principal investigator also report serious adverse events to the US Food and Drug Administration (FDA).
Success: Islet transplantation is considered a success when subjects do not use insulin and they achieve a fasting glucose level not exceeding 140 mg/dL more than three times in a week, and not exceeding two-hour post-prandial values of 180 mg/dL more than four times in a week.
Partial Success: Subjects who have a reduction in insulin requirements but who do not achieve insulin independence and present with a reduction in HbA1c and number of hypoglycemic episodes are considered to have partial success of islet transplantation. Reduction in insulin-requirements are assessed by comparing the pre-transplant insulin requirement recorded over two consecutive days (expressed as insulin units per kg) with the requirement on the two consecutive days preceding the subsequent islet infusion, and the requirements on two consecutive days at six months and again on two consecutive days at one year after the final transplant.
Failure: Absence of measurable levels of C-peptide after transplantation is considered as failure of islet cell transplantation.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adverse Events Including Laboratory Abnormalities at the End of Study Participation
- Frequency of adverse events including laboratory abnormalities
- HbA1C (less than 6.1% is considered normal)
- Glucose control and absence of hypoglycemic coma/unawareness, as evidenced by no further requirement for third-party assistance or hospital attendance resulting from a severe hypoglycemic episode
- Renal function, measured both by serum creatinine and calculated GFR using the Cockroft \& Gault
- Lipid profiles for cholesterol, triglycerides, low density lipoprotein (LDL) and high density lipoprotein (HDL)
- PRA
- Doppler ultrasound to exclude or document portal vein thrombosis
- Immunosuppressive drug trough levels
- Renal clearance (GFR)
- Liver function tests
- Diagnosis of opportunistic infections, e.g., CMV
Measured: 15 months after the last transplant
Number of Participants With Insulin Independence at End of Study Participation
Primary efficacy outcome: independence from insulin injections with adequate control of blood glucose in subjects with Type 1 diabetes. Transplant is considered a success when 2 weeks after their last transplant, subjects are not using insulin, and fasting glucose levels do not exceed 7.8 mmol/L (140 mg/dL) more than 3 times/week, and two-hour post-prandial glucose values do not exceed 10 mmol/L (180 mg/dL) more than 4 times/week. During the 15 months after last transplant, a subject will be considered a success if an illness or other event (e.g., high tacrolimus level) causes need for insulin not exceeding 14 days providing evidence of graft rejection is not apparent. The proportion of subjects who are insulin independent and meet criteria for glucose control will be determined at 2 weeks and 1, 3, 6, 12, and 15 months following their final islet transplant.
Measured: End of 15 Month Study Participation/Follow-up
Number of Participants With HbA1c Less Than or Equal to 6.5 & Free of Severe Hypoglycemic Events
HbA1c less than or equal to 6.5 at end of 15 month study participation, and lack of or free from severe hypoglycemic events, defined as an event with symptoms compatible with hypoglycemia in which the subject required the assistance of another person and which was associated with either a blood glucose level < 50 mg/dl (2.8 mmol/L) or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration.
Measured: At end of 15 month study participation

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Islet Cell Transplant and Islet Cell Transplant plus in people with Diabetes Mellitus, Type 1, run by University of Illinois Chicago at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Adverse Events Including Laboratory Abnormalities at the End of Study Participation (time frame: 15 months after the last transplant). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00566813, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
