Modification of the "Edmonton Protocol" to Allow for Successful Islet Transplantation From a Single Pancreas and Extension of the "Edmonton Protocol" to Kidney Transplant Recipients
A Phase 1 study testing human cadaveric islet cell transplantation in people with Diabetes Mellitus, run by National Center for Research Resources (NCRR) at 1 site in United States.
Trial summary
The experience of the Edmonton Group with islet transplantation and use of the "Edmonton Protocol" provides much promise for T1DM patients. However, the need to use 2 or more donor pancreases to achieve freedom from insulin shots limits the widespread use of this protocol. Read more about this study

About this study
Official title: Modification of the "Edmonton Protocol" to Allow for Successful Islet Transplantation From a Single Pancreas and Extension of the "Edmonton Protocol" to Kidney Transplant Recipients (Project 1 of JDFI Washington University Center for Islet Transplantation)
The experience of the Edmonton Group with islet transplantation and use of the "Edmonton Protocol" provides much promise for T1DM patients. However, the need to use 2 or more donor pancreases to achieve freedom from insulin shots limits the widespread use of this protocol. Two classes of oral antidiabetic drugs improve insulin action and reduce the amount of insulin needed to have normal blood sugars. The first part of the proposed project (Group 1) will use these drugs in conjunction with the Edmonton Protocol to allow for successful islet transplantation from islets isolated from a single pancreas.
The Edmonton Protocol is a treatment, not a cure. It requires the long-term use of powerful immunosuppressive drugs that are expensive and increase the risk of infection and cancer. T1DM patients who have a functioning kidney transplant already have to use immunosuppressive drugs, and they are still at risk of recurrent diabetic kidney disease and other complications of diabetes. Islet transplantation in these patients has only rarely been successful in the past in part because the usual immunosuppressive drugs used in kidney transplantation cause diabetes and actually harm the transplant kidney in other ways. The immunosuppressive drugs used in the Edmonton Protocol are less likely to cause diabetes and are also less harmful to the kidney. In the second part of this project (Group 2), we will transplant islets into kidney transplant patients after they have switched to the immunosuppressive medications used in the Edmonton Protocol. Even if some of the patients do not get islet transplants or still need insulin shots after islet transplantation, we expect to see improvement in kidney function and blood glucose control.
Read the detailed description
We anticipate that successful islet transplantation will establish a group of islet cell transplant patients who have normal blood sugars and do not need insulin injections. Some of this group will have received a kidney transplant as well. All these patients will be studied in great detail along with other investigators in our islet cell program to understand better the mechanisms of efficacy and side effects of islet transplant and these new immunosuppressive drugs.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The experience of the Edmonton Group with islet transplantation and use of the "Edmonton Protocol" provides much promise for T1DM patients. However, the need to use 2 or more donor pancreases to achieve freedom from insulin shots limits the widespread use of this protocol. Two classes of oral antidiabetic drugs improve insulin action and reduce the amount of insulin needed to have normal blood sugars. The first part of the proposed project (Group 1) will use these drugs in conjunction with the Edmonton Protocol to allow for successful islet transplantation from islets isolated from a single pancreas.
The Edmonton Protocol is a treatment, not a cure. It requires the long-term use of powerful immunosuppressive drugs that are expensive and increase the risk of infection and cancer. T1DM patients who have a functioning kidney transplant already have to use immunosuppressive drugs, and they are still at risk of recurrent diabetic kidney disease and other complications of diabetes. Islet transplantation in these patients has only rarely been successful in the past in part because the usual immunosuppressive drugs used in kidney transplantation cause diabetes and actually harm the transplant kidney in other ways.

The record says: status not confirmed, as of the sponsor's last update on 24 Jun 2005. 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 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
