About this study
Official title: Islet Cell Transplantation Alone and CD34+ Enriched Donor Bone Marrow Cell Infusion in Patients With Type 1 Diabetes Mellitus; Steroid Free Regimen
SPECIFIC AIMS:
- To reverse hyperglycemia and insulin dependency in patients with Type 1 diabetes mellitus by islet cell transplantation.
- To induce a state of donor specific tolerance and eliminate the need for continuous immunosuppressive therapy by simultaneous transplantation of donor bone marrow cells with islets and utilization of the monoclonal antibody Campath-1H for induction of Immunosuppression.
- To assess long-term function of successful islet cell transplants in patients with Type 1 diabetes mellitus.
- To determine whether the natural history of the microvascular, macrovascular and neuropathic complications are altered following successful transplantation of islet
Read the detailed description
In our current protocol (IRB #2000/0024) the immunosuppressive regimen, comprised of induction with daclizumab and maintenance therapy with sirolimus and tacrolimus, has been combined with the infusion of CD34+ enriched donor bone marrow stem cells in an attempt to create a chimeric state and hence induce donor tolerance. This strategy was tested by evaluating graft survival following the removal of all immunosuppressive medication after one year.

| Study group | Role | What they receive |
|---|---|---|
| Islet Transplantation and Bone Marrow | Experimental | Administration of islets and infusion of CD34 enriched Bone Marrow cells in subjects with type 1 diabetes, impaired awareness of hypoglycemia and severe hypoglycemia. Receives: Biological: Islet Transplantation and Bone Marrow |
What is being measured
The primary outcome is the main question the study is designed to answer.
The Achievement of Persistent Islet Function Following Cessation of Immunosuppression.
Immunosuppression was never discontinued. Patients elected to move to other trials to receive additional islet infusions. Since immunosuppression was never discontinued we were not able to evaluate the primary endpoint.
Measured: for the duration of islet graft function
A Reduction or Absence of Rejection Episodes
Number of rejection episodes after transplantation. Immunosuppression was never discontinued. Patients elected to move to other trials to receive additional islet infusions. Since immunosuppression was never discontinued we were not able to evaluate the primary endpoint.
Measured: for the duration of islet graft function
Secondary outcomes (2)
Number of Subjects With Basal C-peptide Greater Than 0.5 ng/ml
Number of subjects with basal C-peptide greater than 0.5 ng/ml prior to weaning of immunosuppression;
Measured: for the duration of islet graft function
Number of Subjects With Reduction of Severe Hypoglycemia and Improvement in Hypoglycemia Awareness
Number of subjects with reduction of episodes of severe hypoglycemia and the presence of awareness of hypoglycemia
Measured: for the duration of islet graft function

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Islet Transplantation and Bone Marrow in people with Type 1 Diabetes Mellitus, run by University of Miami 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 29 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: stopped early, as of the sponsor's last update on 4 Apr 2017. 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 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 10 Feb 2014). 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?
The Achievement of Persistent Islet Function Following Cessation of Immunosuppression. (time frame: for the duration of islet graft function). The study lists 2 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 NCT00315614, which also lists 1 linked publication.
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 4 Apr 2017.
