Interferon-γ plus donor immune cells to fight AML/MDS after partial donor transplant
Official title: Interferon-γ in combination with donor leukocyte infusion to treat relapsed acute myeloid leukemia and myelodysplastic syndromes after haploidentical donor stem cell transplantation
Funded at University of Pittsburgh at Pittsburgh · NIH-11453101 · Data updated 2026-11-12
This project tests a therapy that adds a signaling protein, IFN-γ, with donor immune cells to help treat relapsed AML/MDS after a haploidentical stem cell transplant.

Who could benefit from this research
✓Could help
Adults with relapsed AML or MDS after haploidentical stem cell transplantation who are eligible for donor lymphocyte infusion and IFN-γ therapy.
✕Less likely to help
Patients who do not respond to IFN-γ or experience unacceptable toxicity may not benefit.
What this research studies
After a stem cell transplant from a partially matched donor, relapse of AML or MDS is common and deadly. The study builds on prior work showing that IFN-γ signaling helps donor immune cells target leukemia cells while aiming to limit graft-versus-host disease. In patients who relapse after haploidentical transplantation, the team will evaluate safety and initial effectiveness of combining IFN-γ with donor lymphocyte infusions. The trial leverages learnings from prior trials in matched donors and preclinical data to inform this haploidentical setting. If successful, this approach could improve durable remissions for people with relapsed AML/MDS after haploidentical transplants.
Why it matters
Potential benefit: If successful, patients could experience longer remission and potential cures due to a strengthened graft-versus-leukemia effect.
How similar studies have gone: Early trials in matched donors showed some durable remissions with IFN-γ plus DLI, guiding this haploidentical study.
