Purpose

Patients with graft failure or delayed engraftment may benefit from a hematopoietic stem cell boost or an additional hematopoietic stem cell transplantation procedure. In such settings standard immune suppression strategies are avoided due to their myelosuppressive nature. Therefore those patients are at increased risk of graft versus host disease, and the infusion of a CD34 selected graft would reduce such a risk. The infusion of CD34 selected graft using CliniMACS plus is currently FDA FDA-approved indication for acute myeloid leukemia. However, the use of the Prodigy would streamline the processing, in terms of hands-off procedure, allowing to provision of this product to the patients without strains on the cell therapy lab team. This procedure has been demonstrated safe and effective in several single-center studies and is currently in advanced phase investigation in several studies for malignant and non-malignant conditions.

Patients status post allogeneic hematopoietic stem cell transplantation for a neoplastic hematologic disorder with the need of a CD34 selected stem cell boost for graft failure or low graft function will receive a CD34 selected hematopoietic stem cell infusion with or without preceding conditioning. Fludarabine 25 mg/mq day 1 - 5 + 2 Gray Total body irradiation depending on clinician's discretion (with the addition of cyclophosphamide 14.5 mg/kg for two doses for haploidentical or matched unrelated donor with at least one major HLA mismatch). Recommendation to use a conditioning regimen include complete loss of donor chimerism, trilineage cytopenias.

Detailed Description

Patients eligible to be treated on this status are status post allogeneic hematopoietic stem cell transplantation for a neoplastic hematologic disorder with the need of a CD34 selected stem cell boost for graft failure or low graft function (e.g. marrow cellularity reduced per age and/or dropping donor chimerism with cytopenias and/or platelets or red blood cells transfusion requirement).

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
