The relapse of acute leukemia, MDS and blast phase CML after allogeneic transplantation affects approximately 1/3 to 1/2 of all transplant recipients and is the main cause of treatment failure. There is currently no effective standard treatment for this condition.
This study will test the activity and feasibility of using a regimen to boost the immune system in order to treat AML, ALL, blast phase CML, and MDS relapse after allogeneic transplantation.

This is a pilot phase II open label study testing the activity and feasibility of utilizing a regimen to boost the immune system in order to treat AML, ALL, blast phase CML, and MDS relapse after allogeneic transplantation. The regimen is a step-wise use of withdrawal of immunosuppression, cytoreduction if needed, administration of GM-CSF and pegylated IFN α-2b to patients who relapsed after an allogeneic transplant and will assess efficacy.
Relapse is the major problem following allogeneic hematopoietic progenitor cell transplants. There is currently no standard way to treat leukemia that relapsed after transplant, and patients have a poor prognosis.
A retrospective analysis of patients treated at Emory showed that administration of GM-CSF and interferon-alpha-2b was well-tolerated and affected long-term remissions in a small number of relapsed patients (after allogeneic transplant). Pre-clinical and clinical data from ours and other centers showed that relapsed leukemic blasts have down-regulation of co-stimulatory molecules and a tendency to evade the immune system. Cytokines can up-regulate co-stimulatory molecules on leukemic blasts and have been shown to increase the cytotoxicity of T-cells. This effect may be beneficial as a graft vs. leukemia effect for patients with relapse after allogeneic transplant.
Ages Eligible for Study: | 1 Year and older |
Genders Eligible for Study: | Both |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Patients who have received an allogeneic transplant to treat AML, ALL, MDS, or CML and have relapse or progression of their AML, ALL, MDS, or CML are eligible to participate in the study. Relapse is defined as: reappearance of leukemic blasts as determined by morphologic analysis of the blood or marrow, reappearance of a phenotypic population of leukemia blasts by flow cytometric analysis of the blood or marrow, reappearance of a chromosome abnormality which is associated with the original leukemia as determined by chromosomal or FISH testing (ex: a translocation between chromosomes 9 and 22 for CML), reappearance of the molecular marker which is associated with the original leukemia as determined by PCR (ex: BCR-ABL for CML or ALL).
*Patients who received allogeneic transplantation to treat AML, ALL, MDS, or CML with detectable disease, and did not achieve remission of their leukemia after transplant are eligible.
