Interferon-γ (IFN-γ) With Donor Leukocyte Infusion to Treat Relapsed Acute Myeloid Leukemia and Myelodysplastic Syndromes Post Allogeneic Hematopoietic Stem Cell Transplantation

NCT06529731 · Status: RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 45

Summary

This phase 2 study aims to confirm the efficacy seen in the prior phase 1 trial, and further contribute to this effort through the collection of leukemia cells pre- and post- in vivo IFN-γ therapy. As in the previously conducted phase 1 trial, this trial will test whether leukemia blasts were responsive to IFN-γ in vitro and in vivo, with single-cell RNA sequencing (scRNAseq) conducted to understand the transcriptomic changes induced by IFN-γ in leukemia cell subsets, including those with stem cell characteristics.

Conditions

Interventions

DRUG

Interferon gamma-1b

ACTIMMUNE/Interferon gamma-1b is a single-chain polypeptide containing 140 amino acids that is produced by fermentation of a genetically engineered Escherichia coli bacterium containing the DNA which encodes for the recombinant protein. Interferon gamma-1b is part of a drug regimen used to treat Chronic Granulomatous Disease, or CGD. CGD is a genetic disorder, usually diagnosed in childhood, that affects some cells of the immune system and the body's ability to fight infections effectively.

BIOLOGICAL

Donor Leukocyte Infusion (DLI)

Donor lymphocyte infusion is a procedure that transfers healthy white blood cells (lymphocytes) from a bone marrow or stem cell donor to a recipient's blood. An infusion of healthy lymphocytes helps the recipient's immune system get rid of remaining cancer cells if they have a relapse after a bone marrow or stem cell transplant for blood cancer.
