Brief Summary

This randomized phase II trial studies how well multi-antigen cytomegalovirus (CMV)-modified vaccinia Ankara vaccine works in reducing CMV related complications in patients with blood cancer who are undergoing donor stem cell transplant. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill cancer cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine if multi-antigen CMV-modified vaccinia Ankara vaccine (CMV-modified vaccinia Ankara [MVA] triplex) reduces the frequency of CMV events, defined as reactivation or CMV disease in CMV+, haploidentical hematopoietic cell transplantation (haploHCT) recipients.

SECONDARY OBJECTIVES:

I. To evaluate the safety and tolerability of CMV-MVA triplex in vaccinated, haploHCT recipients by assessing the following: non-relapse mortality (NRM) at 100 days post hematopoietic cell transplantation (HCT), severe (grade 3-4) acute graft versus host disease (GVHD), and grade 3-4 adverse events (AEs) probably or definitely related to the vaccination within 2 weeks from each vaccination.

II. To characterize CMV related events in recipients of CMV-MVA triplex compared to placebo, by assessing time to viremia (number of days from transplantation to the date of >= 1250 IU/mL), duration of viremia, recurrence of viremia, incidence of late CMV viremia/disease (> 100 and =< 360 days post HCT), use of antiviral drugs (triggered by clinically significant viremia of >= 1250 IU/mL), cumulative number of CMV specific antiviral treatment days.

III. To evaluate the impact of CMV-MVA triplex on transplant related outcomes by assessing the incidence of acute graft versus host disease (aGVHD), chronic GVHD, relapse, non-relapse mortality, all-cause mortality, infections.

IV. To determine if CMV-MVA triplex increases levels, function and kinetics of CMV-specific T cell immunity in vaccinated compared to placebo treated, CMV seropositive HCT-recipients.

V. To determine whether vaccination induces adaptive natural killer (NK) cell population changes, and increase in the highly cytotoxic memory NKG2C+ NK cell.

VI. To compare GVHD biomarkers between the vaccine and placebo groups.

OUTLINE: Patients are randomized into 1 of 2 arms.

ARM I: Patients receive multi-antigen CMV-modified vaccinia Ankara vaccine intramuscularly (IM) on days 28 and 56 post-HCT.

ARM II: Patients receive placebo IM on days 28 and 56 post-HCT.

After completion of study treatment, patients are followed up at 100, 140, 180, 270, and 365 days, and then periodically for 3 years.

Eligibility Criteria

Inclusion Criteria

• All subjects must have the ability to understand and the willingness to sign a written informed consent
• Participant must be willing to comply with study and/or follow-up procedures, including willingness to be followed for one year post-HCT
• Planned peripheral blood stem cell (PBSC) or bone marrow (BM) HCT for the treatment of the following hematologic malignancies:

• Lymphoma (Hodgkin and non-Hodgkin)
• Myelodysplastic syndrome
• Acute lymphoblastic leukemia in first or second remission (for acute lymphoblastic leukemia/lymphoblastic lymphoma, the disease status must be in hematologic remission by bone marrow and peripheral blood; persistent lymphadenopathy on computed tomography [CT] or CT/positron emission tomography [PET] scan without progression is allowed)
• Acute myeloid leukemia in first or second remission
• Chronic myelogenous leukemia in first chronic or accelerated phase, or in second chronic phase
• Other hematologic malignancies judged appropriate by the clinical principal investigators (PIs), including chronic lymphocytic leukemia, myeloproliferative disorders and myelofibrosis; patients with multiple myeloma and those with non-malignant disease such as aplastic anemia are excluded

• Adult cases of multiple myeloma (MM) are excluded; adults with aplastic anemia are excluded; patients undergoing a second haploHCT are not eligible (patients who have undergone a previous autologous HCT are eligible)
• Patients receiving myeloablation (MA) or reduced intensity conditioning (RIC) are allowed
• CMV seropositive (recipient)
• Planned related HCT with molecular 3/6 (haploidentical) intermediate/high resolution human leukocyte antigen (HLA) donor allele matching
• Planned HCT with minimal to no-T cell depletion of graft
• Conditioning and immunosuppressive regimens according to institutional guidelines are permitted
• Negative serum or urine beta-human chorionic gonadotropin (HCG) test (female patient of childbearing potential only) within two weeks of registration
• Seronegative for human immunodeficiency virus (HIV), hepatitis C virus (HCV) and active hepatitis B virus (HBV) (surface antigen negative) within 2 months of registration and no history of disseminated cutaneous human papillomavirus (HPV) related disease
