New device aims to tame immune attack after stem cell transplants
NCT ID NCT04337515
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a device that removes specific immune cells from donated stem cells before transplant. The goal is to lower the risk of graft-versus-host disease, where donor cells attack the patient's body. Up to 90 children and young adults (ages 0-30) will receive these treated cells. The main focus is on safety and how well the approach prevents severe GVHD in the first 100 days.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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
