About this study
Official title: Phase I/II Study of Allogeneic Hematopoietic Stem Cell Transplantation From an HLA-partially Matched Family Donor After TCR Alfa Beta Negative Selection in Pediatric Patients Affected by Hematological Disorders
Allocation: Non-Randomized Endpoint Classification: Safety/Feasibility Intervention Model: Single Group Assignment Masking: Open Label Primary Purpose: Treatment Study to assess the feasibility and safety of the infusion of a T cells receptor (TCR) alfa beta depleted graft in pediatric patients affected by malignant and non-malignant hematological disorders and receiving an Hematopoietic stem cell transplantation (HSCT) from a Human leukocyte antigen (HLA) partially matched family donor.
Read the detailed description
In this study the hypothesis is that the transplantation of Peripheral blood stem cells (PBSC)selectively depleted of TCR alfa beta T lymphocytes would offers some advantages over the use of positively selected CD34+ stem cells because of the presence of other non-stem ancillary cells (in particular Natural killer (NK) and alfa beta T cells) that might have potential positive effects on the outcome of the transplant.
The clinical relevance of NK-cell alloreactivity has been demonstrated in adult patients affected by Acute myeloid leukemia (AML) and given T-cell depleted HSCT from an HLA-disparate relative where a subgroup of patients had a particularly low risk of leukemia relapse. These patients belonged to the group transplanted from a donor having NK cells that were alloreactive towards recipient targets i.e. the patient cells express HLA-class I alleles that do not share the inhibiting allelic determinants recognized by Killer immunoglobulin-like receptors (KIR) on donor NK cells. The emergence of this concept of NK-cell alloreactivity has represented a sort of revolution in the field of Haplo-identical hematopoietic stem cell translantation (haplo-HSCT), as the presence of alloreactive NK cells has been shown to positively affect the outcome of transplantation in adults and to display a Graft versus leukemia (GvL) effect that can compensate for the lack of T-specific anti-tumor effect.
The purpose of this study is to evaluate the feasibility and safety of the selective infusion of TCR alfa beta T cell depleted graft in pediatric patients affected by malignant or non malignant hematological disorders and receiving an HSCT from a partially matched family donor.
This study will provide new data on the feasibility and the safety of using a TCR alfa beta T cell depleted graft instead of fully T cell depleted graft to improve the outcome of patients receiving a haplo-HSCT for the treatment of hematological disorders.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing TCR alfa beta T cell depletion in people with Acute Lymphoblastic Leukemia and Leukemia Acute Myeloid - AML, run by Mariella Enoc at 1 site in Italy.
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 8 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 23 Jan 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 Italy. 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 combined 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.
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?
CD34+ cells (time frame: up to 3 month). 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 NCT01810120, which also lists 29 linked publications.
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 23 Jan 2017.
