About this study

Official title: A One-Year, Single-Center, Prospective, Open-Label Study of the Safety, Tolerability, and Preliminary Efficacy of Anti-Thymocyte Globulin, Cyclosporine, and RAD in Type 1 Diabetic Islet Transplant Recipients

This study was designed to test the safety and efficacy of up to 3 pancreatic alloislet transplants in type 1 diabetic patients with hypoglycemia unawareness. 6 subjects were transplanted under this protocol using anti-thymocyte globulin induction immunosuppression and everolimus with cyclosporine maintenance immunosuppression.

Read the detailed description

This is a Phase I/II study designed to assess the safety and efficacy of sequential islet allotransplantation for the reestablishment of stable glycemic control in type 1 diabetic recipients. A total of 6 patients with type 1 diabetes have received up to three transplants of islets from different donor pancreases.

Potential candidates for islet allotransplantation included patients age 18 and older with type 1 diabetes. Induction immunotherapy for the first transplant consisted of anti-thymocyte globulin; basiliximab was used for any subsequent transplants. Peritransplant anti-inflammatory treatment with etanercept was given for each islet transplant. Maintenance immunosuppression is with cyclosporine and RAD. It is felt that those patients in whom metabolic lability/instability, reduced awareness of hypoglycemia, poor glycemic control, and progressive secondary complications persist despite continued and intensive efforts made in close cooperation with their diabetes care team are particularly likely to have a favorable benefit/risk ratio.

Adverse events, irrespective of their presumed relationship to the transplantation of allogeneic islets and/or protocol-regulated treatment products (concomitant therapy), are being monitored and recorded throughout the first year after the final islet transplant.

The proportion of single and sequential donor islet allograft recipients with full (insulin independence and HbA1c <7%) and partial (insulin dependence, basal or arginine-stimulated C-peptide levels of greater or equal to 0.5 ng/mL and HbA1c <7%) islet graft function at one year after the final islet transplant will be assessed. The impact of islet transplantation on quality of life will also be assessed.

The predictive value for posttransplant insulin independence of factors such as insulin resistance before and at intervals after pancreatectomy, cellular composition of the transplant, number of beta cells transplanted; and viability and insulin secretory response of isolated islets are being assessed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Allogeneic Islets of LangerhansBiological

    Also called Islets

    Up to 3 intraportal infusions of cadaveric pancreatic islets of Langerhans. First infusion to contain at least 5,000 islet equivalents/kg body weight. Subsequent infusions to contain at least 3,000 islet equivalents/kg body weight.

  • EverolimusDrug

    Also called RAD

    Loading dose of 3 mg PO on day -2 relative to transplant, followed at least 12 hours later by dose of 1.5 mg PO BID. The daily dose will be adjusted according to the whole blood 12-hr trough to target 3-15 ng/ml for the first 3 months and 3-12 ng/ml thereafter.

  • anti-thymocyte globulinDrug

    Also called ATG, Thymogloblin

    A total of 6 mg/kg IV over 12 hours on days -2, -1, 0, +1, and +2. The dose will be 0.5 mg/kg on day -2, 1.0 mg/kg on day -1, and 1.5 mg/kg on days 0, +1, and +2.

  • CyclosporineDrug

    Also called Neoral

    Cyclosporine started on day +1 relative to the first islet transplant. Initial dose of 3 mg/kg/day administered in 2 divided doses; then adjusted to maintain target levels of 400 (350-500) ng/mL for the first three months following islet transplant and 300 (200-350) ng/mL thereafter.

    Measured: 1 year

  2. • Incidence and severity of hypoglycemia during the first year after the first and any subsequent islet transplants.

    Measured: 1 yr

  3. • The proportion of recipients who develop alloantibodies directed at islet donor alloantigens during the first year after the first and any subsequent islet transplants.

    Measured: 1 year

Secondary outcomes (5)
  1. • The proportion of subjects who achieve insulin independence in the first year after single-donor or sequential transplantation.

    Measured: 1 year

  2. • The proportion of islet allograft recipients with full and partial islet graft function at one year after the most recent islet transplant.

    Measured: 1 year

  3. • Glycemic control and insulin secretory responses during the first year after the first and any subsequent transplants.

    Measured: 1 year

  4. • The effect of donor age, pretransplant islet insulin secretory response in vitro, number of transplanted islet equivalents (IEQ), number of transplanted beta cells, pretransplant recipient insulin requirements and action, recipient body mass index (BM

    Measured: Day of transplant

  5. • The impact of islet transplantation on the quality of life of transplant recipients.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Allogeneic Islets of Langerhans, Everolimus and anti-thymocyte globulin in people with Type 1 Diabetes Mellitus and Hypoglycemia, run by University of Minnesota 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 4 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 8 May 2008. 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?

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?

• The incidence, timing, and severity of adverse events during one year after the first and any subsequent islet transplants. (time frame: 1 year). 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?
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 8 May 2008.
