Interferon-γ and Donor Leukocyte Infusion for Relapsed AML/MDS

This study is testing a new treatment for acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) that has returned after an allogeneic hematopoietic stem cell transplant (a type of bone marrow transplant). It combines Interferon gamma-1b, a protein that helps the immune system, with Donor Leukocyte Infusion (DLI), which transfers healthy white blood cells from your donor to you. The goal is to see if this combination can help your immune system fight off the remaining cancer cells. Researchers will also study your leukemia cells to understand how they respond to Interferon gamma-1b. To join, you must be at least 18 years old and have relapsed AML or MDS after a transplant from a well-matched donor. The main goal is to see how long people live without the cancer returning (event-free survival) after one year. The study is currently recruiting about 45 participants.

  • Event-free survival (EFS)At 1 year

    Cohort 1: Occurrence of treatment failure, hematologic relapse from a CR (complete remission)/CRh/Cri), or death observed from start of IFN-γ treatment. Patients alive at 1 year after start of treatment will be censored on the date of last contact.

  • Incidence of steroid- and ruxolitinib- refractory GVHD within 12 weeks after the first dose of IFN-γ12 Weeks

    Cohort 2: Lack of improvement after 7 days of methylprednisolone 2 mg/kg, AND, either of the following 1. Progression of graft-vs-host disease (GVHD) compared with baseline after 10 days of ruxolitinib, based either on an objective increase in stage/grade or new organ involvement Or 2. Lack of improvement in GVHD (PR or better) compared with baseline after at least 14 days of ruxolitinib.
