About this study

Official title: Allogeneic Hematopoietic Stem Cell Transplant for Patients With Immunologic or Histiocytic Disorders Using a Non-Myeloablative Preparative Regimen to Achieve Stable Mixed Chimerism

This study tests the clinical outcomes of a preparative regimen of fludarabine (FLU), anti-thymocyte globulin (ATG)/or Campath, and melphalan; followed by hematopoietic stem cell transplant, and a post transplant regimen of Cyclosporin A (CsA) in patients with immunologic or histiocytic disorders. The researchers hypothesize that this regimen will have a positive effect on post transplant engraftment and the incidence of graft-versus-host-disease (GVHD).

Patients will be randomized biologically into one of 3 arms based upon donor availability: (a) human leukocyte antigen (HLA) genotypic matched sibling donor, (b) HLA phenotypic matched unrelated peripheral blood stem cell (PBSC) donor, (c) two HLA 0-2 antigen mismatched unrelated cord blood donors (double cord).

Read the detailed description

Prior to transplantation, subjects will receive Melphalan, Fludarabine and Anti-Thymocyte Globulin (ATG) or Campath. These three drugs are being given to subjects to help the new stem cells take and grow. On the day of transplantation, subjects will receive stem cells transfused via intravenous (IV) catheter.

After stem cell transplantation, subjects will be given Cyclosporin A (CsA) and mycophenolate mofetil (MMF) to reduce the risk of graft-versus-host disease, the complication that occurs when the donor's stem cells react against the patient.

What is being measured

The primary outcome is the main question the study is designed to answer.

    >10% Donor Cells at Day 100

    Measured: Day 100

Secondary outcomes (9)
  1. Percentage of Donor Chimerism at 100 Days

    The percent of recipient bone marrow and blood cells that are of donor origin.

    Measured: Day 100

  2. Percentage of Donor Chimerism at 180 Days

    The percent of recipient bone marrow and blood cells that are of donor origin.

    Measured: Day 180

  3. Percentage of Donor Chimerism at 365 Days

    The percent of recipient bone marrow and blood cells that are of donor origin.

    Measured: Day 365

  4. Incidence of Grade 2-4 Acute Graft Versus Host Disease (aGVHD)

    Acute graft versus host disease (aGVHD) is a reaction occurring within the first 100 days after transplant where the T- cells of the donor graft attacks the recipient's (host's) skin, GI tract, liver and other organs. The severity of aGVHD is graded on a scale of 1 - 4 with the highest number representing the most severe disease.

    Measured: Day 100

  5. Incidence of Grade 3-4 Acute Graft Versus Host Disease (aGVHD)

    Acute graft versus host disease (aGVHD) is a reaction occurring within the first 100 days after transplant where the T- cells of the donor graft attacks the recipient's (host's) skin, GI tract, liver and other organs. The severity of aGVHD is graded on a scale of 1 - 4 with the highest number representing the most severe disease.

    Measured: Day 100

  6. Incidence of Chronic Graft Versus Host Disease (cGVHD)

    Chronic graft versus host disease (cGVHD) is a reaction which typically develops 3 to 6 months after transplant where the T- cells of the donor graft attacks the recipient's (host's) skin, GI tract, liver and other organs.

    Measured: 6 months and 1 year

  7. Number of Subjects Alive at 100 Days

    Measured: Day 100

  8. Number of Subjects Alive at One Year

    Measured: Day 365

  9. Compare Quality of Life (QOL)

    Measured: Pretransplant, 1 year, 2 years and 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Stem Cell Transplant, Fludarabine and Melphalan in people with Hemophagocytic Lymphohistiocytosis and X-Linked Lymphoproliferative Disorders, run by Masonic Cancer Center, 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 5 inclusion and 6 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 28 Dec 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 14 Apr 2017). 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 Subjects With Mixed Chimerism (time frame: Day 100). 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 28 Dec 2017.
