WT1 Vaccine Treatment of Patients in Remission From Acute Myeloid Leukemia (AML) or Acute Lymphoblastic Leukemia (ALL)

Inclusion Criteria: * Morphologic confirmation of a diagnosis of AML or ALL at MSKCC * Patients will have completed induction therapy, achieved 1st CR and will have completed any planned postremission therapy. Patients are not candidates for allogeneic stem cell transplantation. For purposes of this study, patients who are not candidates for allogeneic stem cell transplantation shall be defined as 1) those who do not meet the eligibility criteria of an open allogeneic transplant protocol or 2) those who do not have a suitable available HLA matched donor available or 3) those who refuse to undergo stem cell transplantation or 4) those patients whose disease is characterized by "good risk" features (For AML the following cytogenetic subtypes: t(8;21), inv (16), or t(16;16), t(15;17), normal karyotype with mutated NPM1 and negative for tandem duplication of FLT-3. For ALL: T cell phenotype of any B lineage disease exclusive of t(9;22) or t(4;11) in whom allogenic stem cell transplantation in 1st CR would not be offered as standard of care. * Alternatively, those patients greater than or equal to 60 years of age who have achieved 1st CR and in whom no further postremission chemotherapy is planned may be enrolled * Patients must have documented WT1 + disease. For purpose of this study, this is defined as detectable presence of any WT1 transcript via RT-PCR on a bone marrow performed at MSKCC within 4 weeks prior to the administration of the first dose of vaccine. * Patients must …
