Wilm's Tumor 1 (WT1) Peptide Vaccine for High Risk Hematologic Malignancy

Study Summary

This study will determine the safety and effectiveness of an experimental vaccine in controlling the abnormal growth of cells in patients with myelodysplastic syndrome (MDS, also known as myelodysplasia), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML). It will test whether the vaccine can increase the number of immune cells responding to the cancer and thereby slow progression of the illness, improve blood counts, reduce the need for transfusions of blood and platelets, or even achieve a disease remission. The vaccine contains part of a protein that is produced in large amounts by cells of patients with these cancers and an added substance called Montanide that helps the immune system respond to the vaccine. Sargramostim, another substances that boosts the immune response, is also given. Patients 18 to 85 years of age with MDS, AML, ALL or CML may be eligible for this study. Candidates are screened with a medical history, physical examination, blood tests, chest x-ray and bone marrow biopsy. Women of childbearing age also have a pregnancy test. Participants undergo the following: * Chemotherapy entering the study. * Leukapheresis to collect large amounts of white blood cells for infusion before vaccine administration. * Participants may need placement of a central line (plastic tube, or catheter) in the upper part of the chest to be used for giving chemotherapy, blood or platelet transfusions, antibiotics and white blood cells, and for collecting blood samples. * Weekly vaccine injections for nine weeks, given in the upper arm, upper leg or abdomen. * Sargramostim injections following each vaccination. * Standard of care treatment for MDS, AML, ALL or CML, which may include blood or platelet transfusions, growth factors, and drugs to control underlying disease and potential side effects of the vaccine. * Weekly safety monitoring, including vital signs check, brief health assessment, blood tests and observation

Primary Outcome

Minimum criterion for a cellular immune response was defined as the emergence of detectable T cell frequency against Willm's tumor 1 (WT1) when the pre-study analysis found no response, or a twofold increase in T cell frequency at any post vaccination time point
