About this study

Official title: Islet Transplantation in Type 1 Diabetic Kidney Allograft Recipients: Efficacy of Islet After Kidney Transplantation (CIT-06)

Type 1 diabetes is an autoimmune disease in which the insulin-producing pancreatic beta cells are destroyed, resulting in poor blood sugar control. The purpose of this study is to assess the benefit of islet transplantation in type 1 diabetic (T1D) kidney transplant recipients.

Read the detailed description

Type 1 diabetes is commonly treated with the administration of insulin, either by multiple insulin injections or by a continuous supply of insulin through a wearable pump. Insulin therapy allows long-term survival in individuals with type 1 diabetes; however, it does not guarantee constant normal blood sugar control. Because of this, long-term type 1 diabetic survivors often develop vascular complications, such as diabetic retinopathy, an eye disease that can cause poor vision and blindness, and diabetic nephropathy, a kidney disease that can lead to kidney failure and thus kidney transplant. Some individuals with type 1 diabetes develop hypoglycemia unawareness, a life-threatening condition that is not easily treatable with medication and is characterized by reduced or absent warning signals for hypoglycemia. For such individuals, pancreas or pancreatic islet transplantation are possible treatment options. The purpose of this study is to assess the benefit of islet transplantation in type 1 diabetic kidney transplant recipients.

Participants in this study will be type I diabetics who have received a kidney transplant for ESRD.. If subjects have not received ITT in the 12 months prior to enrollment, they must undergo a period of standardized diabetes care by an experienced diabetologist at the transplant center using the current ADA's standards of medical care in diabetes. Throughout the study, all participants will remain on the immunosuppressive therapy intended for their kidney. Participants will receive up to three separate islet transplants and a regimen of immunosuppressive medications consisting of antithymocyte globulin (ATG) and etanercept. They will begin receiving ATG 2 days prior to transplant and will continue to receive ATG until Day 2 post-transplant. Etanercept will be given on the day of transplant and on Days 3, 7, and 10 post-transplant.

Transplantations will involve an inpatient hospital stay and infusion of islets into a branch of the portal vein. Participants who do not achieve or maintain insulin independence by Day 30 post-transplant will be considered for a second islet transplant. Participants who remain dependent on insulin for longer than 30 days after the second transplant and who show partial graft function will be considered for a third islet transplant. Daclizumab will be used in place of ATG for the second and third transplants, if they are necessary. Participants who do not meet the criteria for a subsequent transplant will enter a reduced follow-up period.

There will be approximately 15 study visits. A physical exam, review of adverse events, and blood collection will occur at most visits. A chest x-ray, abdominal ultrasound, electrocardiogram, quality of life questionnaires, and urine collection will occur at some visits. Participants will also test their own blood glucose levels throughout the study. A 36-month follow-up period will take place after the participant's last transplant, consisting of 8 additional visits.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Islet transplantation, Antithymocyte Globulin and Daclizumab or Basiliximab in people with Type 1 Diabetes Mellitus, run by National Institute of Allergy and Infectious Diseases (NIAID) at 10 sites in 2 countries.

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 6 inclusion and 37 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 20 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Proportion of patients w/HbA1c </= to 6.5% and an absence of severe hypoglycemic events or a reduction in HbA1c of at least 1 point and an absence of severe hypoglycemic events (time frame: At 1 year after first islet infusion). It is what the study was designed to measure, not a finding.

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 20 Oct 2017.
