Detailed Description

Severe graft dysfunction, such as the degree of donor chimerism predominantly in the myeloid compartment is one of major problem in patients with Wiskott-Aldrich syndrome (WAS), especially after hematopoietic stem cell transplantation (HSCT) from alternative donor. It often leads to the development of severe thrombocytopenia or even transplants rejection. In this study the hypothesis is that the use of plerixafor and G-CSF as additional agents in conditioning regimen would offers advantages due to lowing risk of mixed chimerism after HSCT. This effect is based on the fact that simultaneous use of plerixafor with G-CSF is efficient in inducing stem cell release and opening of bone marrow (BM) niches. Moreover, stem cell release probably leads to liberation of host stem cells from the anti-apoptotic effects of the BM stroma for the more powerful effect of chemotherapy.

In this study, the investigators use TCR alpha/beta grafts depletion of the grafts as basic technology for HSCT from haploidentical and unrelated donors approved in Institution.

Thus, the purpose of this study is to evaluate the safety and efficiency of myeloablative conditioning with Plerixafor and G-CSF as additional agents for prevention of graft failure after transplantation with TCR alpha/beta grafts depletion in patients with Wiskott-Aldrich syndrome.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
