Using CliniMACS for T-Cell Depletion in Stem Cell Transplant
Official title: A Feasibility Study of Using the CiniMacs® Device for Alpha/Best T-Cell Depletion in Stem Cell Transplant Recipients
Run by University of California, San Francisco · NCT04337515 · Data updated 2026-11-12
This study is testing if a special device can safely remove certain T-cells from donor blood to help patients getting a stem cell transplant avoid complications like graft-versus-host disease.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are males or females aged 0-30 years requiring an allogeneic hematopoietic cell transplant with a willing and healthy donor.
✕Probably not a fit
Patients with a healthy and willing HLA-identical related donor or those with a life expectancy of less than one month may not benefit from this study.

What this trial studies
This study evaluates the feasibility of using the CliniMACS® device for ex vivo alpha-beta T-cell depletion in patients undergoing allogeneic hematopoietic cell transplant (HCT) to minimize the risk of graft-versus-host disease (GVHD). The CliniMACS® device utilizes a specific antibody to isolate hematopoietic stem cells from donor blood, enhancing the safety and efficacy of the transplant process. The study aims to gather data on the device's performance in a broader context than its current FDA-approved indications, which are limited to specific patient populations. Participants will be closely monitored for outcomes related to GVHD and overall transplant success.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the incidence of graft-versus-host disease in transplant patients, improving their overall outcomes.
How similar studies have gone: Other studies have shown promise in using similar approaches for T-cell depletion, but this specific application with the CliniMACS® device is novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: * Male or female 0-30 years of age at time of transplant admission * Documentation of a disease requiring HCT * A donor (mismatched related or unrelated) must be located who are healthy and willing, and whom are able to donate bone marrow (BM) or peripheral blood stem cells (PBSC). Matched related donors may be used for patients with Fanconi Anemia. * Written informed consent (and assent when applicable) obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study Exclusion Criteria: * Pregnant, breastfeeding, or unwilling to practice birth control during participation in the study * Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data * Presence of a healthy and willing HLA-identical related donor (except when the patient has Fanconi Anemia). * Patient with an anticipated life expectancy of \<1 month * Patients with known hypersensitivity to murine (mouse) proteins or iron dextran
