Allogeneic Stem Cell Transplantation Followed By Targeted Immune Therapy In Average Risk Leukemia (AML/MDS/JMML)

August 4, 2021 updated by: Monica Bhatia, Columbia University

Allogeneic Stem Cell Transplantation Followed By Targeted Immune Therapy In Average Risk Acute Myelogenous Leukemia/Myelodysplastic Syndrome/Juvenile Myelomonocytic Leukemia (AML/MDS/JMML)

Allogeneic stem cell transplantation (AlloSCT) followed by targeted immune therapy Gemtuzumab Ozogamicin patients with acute myeloid leukemia (AML)/juvenile myelomonocytic leukemia (JMML)/myelodysplastic syndromes (MDS) will be safe and well tolerated.

Study Overview

Detailed Description

Gemtuzumab Ozogamicin (CMA-676) is a chemotherapeutic agent consisting of a recombinant humanized anti-CD33 antibody conjugated with calicheamicin, a highly potent cytotoxic antitumor antibiotic. The antibody portion of Gemtuzumab binds specifically to the CD33 antigen, a sialic acid-dependent adhesion protein expressed on the surface of leukemic blasts, normal and leukemic myeloid colony-forming cells, including leukemic clonogenic precursors, but excluding pluripotent hematopoietic stem cells and nonhematopoietic cells. This results in formation of a complex that is internalized, upon which the calicheamicin derivative is released within the lysosomes of the myeloid cell. The free calicheamicin derivative then binds to deoxyribonucleic acid (DNA), resulting in DNA double strand breaks and consequential cell death. Over 80% of AML patients possess myeloid blast cells with CD33 surface antigen expression.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Matched Family Donor

Patients will receive a reduced intensity fludarabine (6 days)/busulfan (2 days) conditioning regimen followed by a stem cell transplant from a related family donor using bone marrow or cord blood stem cells. Then followed by Gemtuzumab Ozogamicin, once at about 2-6 months post alloSCT and once at least 2 months after the first dose. Patients with JMML will also receive cis-retinoic acid (Isotretinoin).

During and following transplantation patients will receive methylprednisolone for immune suppression. Graft-versus-host-disease (GVHD) prophylaxis will consist of tacrolimus, mycophenolate mofetil and additionally methotrexate in recipients of unrelated adult transplants.
