Spots Global Cancer Trial Database for Vaccine Therapy and Basiliximab in Treating Patients With Acute Myeloid Leukemia in Complete Remission

Study Description

Brief Summary: This randomized phase I trial studies the side effects and best way to give vaccine therapy together with basiliximab in treating patients with acute myeloid leukemia (AML) in complete remission. Vaccines made from the WT1 peptide may help the body build an effective immune response to kill cancer cells. Montanide ISA 51 VG and poly-ICLC may enhance this response. Monoclonal antibodies, such as basiliximab, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. It is not yet known whether WT1 126-134 peptide vaccine with Montanide ISA 51 VG is more effective than with poly-ICLC when given together with basiliximab in treating AML

Detailed Description: PRIMARY OBJECTIVES: I. To examine the immunogenicity of WT1 peptide (WT1 126-134 peptide vaccine) emulsified in Montanide (Montanide ISA 51 VG) in elderly patients with AML. II. To determine whether toll-like receptor 3 (TLR3) agonist (poly-L-lysine and carboxymethyl cellulose \[poly ICLC\]) could be a potent immunologic adjuvant, and increases the frequencies of WT1-specific T cells following vaccination. III. To determine whether depletion of regulatory T cells occurs upon administration of the anti-cluster of differentiation (CD)25 monoclonal antibody Basiliximab, and whether this is associated with increased frequencies of WT1-specific T cells following vaccination. IV. To assess whether WT1 vaccination +/- TLR3 agonist (poly ICLC) combined with Basiliximab results in decreased levels of WT1 transcripts in peripheral blood cells compared to WT1 vaccination +/- TLR3 as measured by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). SECONDARY OBJECTIVES: I. To examine the safety and gain preliminary information on efficacy of WT1 peptide vaccination +/- TLR3 agonist (poly ICLC) combined with Basiliximab. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM A: Patients receive WT1 126-134 peptide vaccine emulsified in Montanide ISA 51 VG subcutaneously (SC) on day 0 and then once every 2 weeks. ARM B: Patients receive WT1 126-134 peptide vaccine emulsified in poly-ICLC SC on day 0 and then once every 2 weeks. ARM C: Patients assigned to Arm C receive basiliximab intravenously (IV) over 30 minutes on day -7 and WT1 126-134 peptide vaccine as in Arm A or Arm B, whichever had a superior cellular immune response. In all arms, treatment continues for 12 weeks in the absence of disease progression or unacceptable toxicity. Patients may then receive 6 additional monthly vaccinations. After completion of study treatment, patients are followed up for up to 2 years.
