Naive T Cell Depletion for Preventing Chronic Graft-versus-Host Disease in Children and Young Adults With Blood Cancers Undergoing Donor Stem Cell Transplant

Is NCT03779854 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments for acute biphenotypic leukemia.

Phase 2RecruitingFred Hutchinson Cancer CenterNCT03779854Data as of May 2026

Treatment: Thiotepa · Fludarabine · Cyclophosphamide · Busulfan · Tacrolimus · MethotrexateThis phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening.
