Vaccine Therapy in Preventing Cytomegalovirus Infection in Patients With Hematological Malignancies Undergoing Donor Stem Cell Transplant

PRIMARY OBJECTIVES: I. To discover whether two administrations of 2.5 mg tetanus (Tet)-CMV peptide co-injected with 1 mg of PF-03512676 (tetanus-CMV fusion peptide vaccine), by subcutaneous (SC) route on days 28 and 56 post-hematopoietic cell transplantation (HCT) are safe and well tolerated in human leukocyte antigen (HLA) A\*0201 CMV-positive recipients of allogeneic HCT. SECONDARY OBJECTIVES: I. To measure levels of CMV-specific T cells in vaccinated compared to unvaccinated HCT recipients (control arm). II. To assess whether vaccination of HCT recipients with Tet-CMV co-injected with PF03512676 reduces expression of programmed death 1 (PD-1) on CMV-specific T cells. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive Tet-CMV + PF03512675 SC on days 28 and 56 post-HCT. ARM II: Patients undergo immune monitoring only. After completion of study treatment, patients are followed up at days 70, 84, 100, 130, 160, and 180.
