5. Study Description

Brief Summary
RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase II trial is studying how well vaccine therapy works in treating patients with Philadelphia chromosome-positive chronic myelogenous leukemia.
Detailed Description
OBJECTIVES: Primary Determine the activity of bcr-abl p210-b3a2 breakpoint-derived pentapeptide vaccine (CMLVAX100), in terms of peripheral blood bcr-abl/abl ratio reduction, in patients with Philadelphia chromosome-positive chronic myelogenous leukemia. Secondary Determine the reduction of molecular residual disease at 3 months in patients treated with this vaccine. Determine the reduction of molecular residual disease at 12 months in patients treated with maintenance boosts of this vaccine. Determine the rate of complete molecular response at any time after vaccination. Determine in vivo and in vitro peptide-specific immune response induced by the vaccine. OUTLINE: This is a prospective, nonrandomized, open-label, multicenter study. Patients receive sargramostim (GM-CSF) subcutaneously (SC) on days 1 and 2 and bcr-abl p210-b3a2 breakpoint-derived pentapeptide vaccine (CMLVAX100) SC on day 2. Treatment repeats every 2 weeks for 6 courses. Patients then receive CMLVAX100 SC once monthly for 3 months and then once every 3 months for 6 months (for a total of 1 year). Patients may receive additional CMLVAX100 SC every 6 months for at least 3 years. Treatment continues in the absence of disease progression or unacceptable toxicity. PROJECTED ACCRUAL: A total of 69 patients will be accrued for this study.
