Trial summary

This protocol studied the effect of administration of a myeloablative pretransplant preparative regimen followed by an infusion of donor stem cells in children with severe sickle cell disease. The donor graft consisted of bone marrow or cord blood derived from a genetically matched sibling. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Diagnosis of severe' disease is denoted by one of the following:
  • Previous central nervous system vaso-occlusive episode with or without residual neurologic findings or
  • Frequent painful vaso-occlusive episodes with significant interference with normal life activities and which necessitates chronic transfusion therapy or

About this study

Official title: Allogeneic Stem Cell Transplantation From HLA/MLC Genotype Identical Donors for Patients With High Risk Sickle Cell Disease

This protocol studied the effect of administration of a myeloablative pretransplant preparative regimen followed by an infusion of donor stem cells in children with severe sickle cell disease. The donor graft consisted of bone marrow or cord blood derived from a genetically matched sibling.

The primary aim of the study was to evaluate how well the donated cells migrated to the bone marrow and begin producing healthy red blood cells, white blood cells and platelets (engrafted), how well the recipients immune system recovered, and assess any regimen related toxicities including a potentially life-threatening transplant related complication called graft-versus-host-disease or GVHD.

Read the detailed description

The secondary objectives of this protocol evaluated the effect of this transplant procedure on the subsequent clinical course of patients with severe SCD. Specifically, to determine whether pre-transplant organ dysfunction (brain, heart, lung, kidney, liver, spleen, etc) resultant from sickle hemoglobinopathy can be reversed following this particular transplant procedure.

What participants receive

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

  • Busulfan, Cyclophosphamide, Horse ATGDrug

    Transplant recipients received a myeloablative conditioning regimen of cyclophosphamide, Anti-Thymocyte Globulin (horse), and Busulfan. Cyclosporine and methotrexate were administered for GVHD prophylaxis.

  • Allogeneic stem cell transplantProcedure or surgery

    Allogeneic stem cell transplant Matched sibling donor transplant Cord blood transplant

What is being measured

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

  1. To evaluate engraftment, GVHD, hematopoietic and immune reconstitution, and regimen-related mortality and morbidity in patients with severe sickle cell disease undergoing transplant using either HLA matched sibling bone marrow or cord blood grafts.

    Measured: March 2007

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Busulfan, Cyclophosphamide, Horse ATG and Allogeneic stem cell transplant in people with Sickle Cell Disease, run by St. Jude Children's Research Hospital 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 7 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 29 May 2009. 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?

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?

To evaluate engraftment, GVHD, hematopoietic and immune reconstitution, and regimen-related mortality and morbidity in patients with severe sickle cell disease undergoing transplant using either HLA matched sibling bone marrow or cord blood grafts. (time frame: March 2007). 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 NCT00186810, 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 29 May 2009.
