About this study

Official title: Haploidentical Hematopoietic Stem Cell Transplantation for Pediatric Patients With Wiskott-Aldrich Syndrome: A Pilot Study

Wiskott - Aldrich syndrome (WAS) is a rare disorder curable only through allogeneic hematopoietic stem cell transplantation. A mismatched family member is an option when no human leukocyte antigen (HLA-immune system type) matched related or matched unrelated donor is available.

This study will evaluate a novel therapeutic strategy for patients with WAS who undergo haploidentical transplantation using a parental donor. To reduce the risk of transplant-related toxicities, participants will receive a reduced intensity chemotherapy and antibody regimen (conditioning treatment). Participants will then receive an infusion of donor stem cells depleted of certain white blood cells called T- and B-lymphocytes. The stem cell depletion processing will be done through the use of the investigational CliniMACS device. A certain number of T-lymphocytes will be added back to the processed stem cell graft prior to infusion into the recipient.

The primary objective of this study is to determine the safety of haploidentical transplantation in WAS patients using this specified conditioning regimen and engineered graft. Safety will be defined in terms of engraftment (meaning how well the graft grows and functions after infusion) and regimen-related toxicity within the first 100 days after transplant.

Read the detailed description

Secondary Objectives in this trial include the following:

  • To estimate the survival of study recipients at one year after infusion of the T- and B-lymphocyte depleted stem cell graft.
  • To assess if the study treatment enables the recipient to generate normal donor-derived B-cell numbers and endogenous IgM, IgG, and IgA production, resulting in a reduction/elimination of the need for intravenous immunoglobulin infusions.
  • To determine if the study treatment results in the ability of the research participant to generate normal donor-derived T cell response and natural killer (NK) cell numbers and function.
  • To describe the incidence of Epstein-Barr virus-lymphoproliferative disease (EBV-LPD) in these transplant recipients.

What participants receive

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

  • Hematopoietic stem cell transplantationProcedure or surgery

    Also called Haploidentical stem cell transplant, Allogeneic stem cell transplant, Mismatched family member donor transplant, T and B cell depletion

    To determine the safety in regards to engraftment and toxicity within 100 days of infusing a haploidentical T- and B-cell depleted hematopoietic stem cell graft into patients with Wiskott-Aldrich syndrome who have received a reduced intensity conditioning regimen.

  • Miltenyi CliniMACS selection systemDevice

    This system depletes the hematopoietic stem cell graft of T and B lymphocytes.

  • Fludarabine, Melphalan, ThiotepaDrug

    Participants will receive a reduced intensity conditioning regimen consisting of Fludarabine, Melphalan, Thiotepa, and OKT3 prior to receipt of the haploidentical stem cell graft. Rituximab will be given in an effort to prevent PTLPD. In addition to T-cell depletion of the donor product, cyclosporine will be given for GVHD prophylaxis.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Hematopoietic stem cell transplantation, Miltenyi CliniMACS selection system and Fludarabine, Melphalan, Thiotepa in people with Wiskott-Aldrich Syndrome, 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 11 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 26 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 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.

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 determine safety in regards to engraftment and toxicity within 100 days post-haploidentical T- and B-cell depleted hematopoietic stem cell transplantation for patients with Wiskott-Aldrich syndrome who received a reduced intensity conditioning (time frame: March 2010). 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 26 Apr 2017.
