About this study
Official title: A Phase II Study of Peripheral Blood Stem Cell Transplantation (PBSCT)From Haploidentical Related Donors for Treatment of Hematologic Malignancies and Hematopoietic Failure States
The purpose of this study is to transplant haploidentical related peripheral blood stem cells (PBSCs) that come from a relative such as a parent, sibling, a child or other relative who has a half-matched tissue type with the recipient (rather than being completely matched) following administration of a reduced-intensity regimen of busulfan, melphalan and alemtuzumab.
Read the detailed description
Fewer than 35% of patients who might benefit from allogeneic HCT have an HLA-identical sib. Transplantation of peripheral blood stem cells (PBSCs) or bone marrow (BM)from HLA-matched or one-locus mismatch unrelated volunteer donors may be an alternative in some patients who lack HLA-matched sib donors. Despite increasing numbers of volunteer unrelated donors in national and international registries, identification of suitable unrelated donors who are matched with the recipient at all HLA-A, -B, -C and -DRB1 loci (8/8 HLA match) or mismatched at one of those loci (7/8 HLA match) is still challenging, especially for patients who are African-American or multiracial. Additionally, the 3- to 4-month delay between initiation of unrelated donor search to HCT is unacceptably long in patients with aggressive hematologic malignancies that are likely to relapse or progress during that interval. Transplantation of single or dual unrelated umbilical cord blood cells (UCB) units is another alternative, although problems with inadequate cell doses, delayed engraftment, graft rejection and infection persist in adult recipients of unrelated UCB transplants.
This is a phase II single-arm open-label study to evaluate the efficacy and safety of haploidentical related allogeneic PBSCT using a nonmyeloablative preparative regimen of intravenous busulfan (Busulfex®), intravenous melphalan (Alkeran®) and intravenous alemtuzumab (Campath®) in subjects who are candidates for related or unrelated allogeneic hematopoietic cell transplantation (HCT; transplantation of bone marrow or PBSCs) but who lack histocompatible related or unrelated donors. This study will also evaluate immunological reconstitution following haploidentical PBSCT by measurement of circulating T cell receptor excision circle (TREC)-positive cells, an indicator of thymic output. Systematic analyses of TREC-positive cells have not been performed in recipients of haploidentical PBSCT after the preparative regimen described in this protocol.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing haploidentical allogeneic PBSC transp in people with Hematologic Neoplasms and Anemia, Aplastic, run by University of Arizona 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 9 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 3 Mar 2016. 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?
The primary efficacy endpoint is the presence of donor lymphohematopoietic chimerism (defined as at least 50% donor cells in the peripheral blood)in peripheral blood by day +100. (time frame: by day +100 (i.e., 100 days after haploidentical PBSCT).). 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 3 Mar 2016; AzTrials last refreshed its copy on 7 Nov 2026.
