About this study
Official title: A Phase II Randomized, Placebo-Controlled, Multicenter Trial to Evaluate the Protective Function of a CMV-MVA Triplex Vaccine in Recipients of an Allogeneic Hematopoietic Stem Cell Transplant
This randomized phase II trial studies the safety and how well multi-peptide cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) vaccine works in reducing CMV complications in patients previously infected with CMV and are undergoing a donor hematopoietic cell transplant. CMV is a virus that may reproduce and cause disease and even death in patients with lowered immune systems, such as those undergoing a hematopoietic cell transplant. By placing 3 small pieces of CMV deoxyribonucleic acid (DNA) (the chemical form of genes) into a very safe, weakened virus called MVA, the multi-peptide CMV-MVA vaccine may be able to induce immunity (the ability to recognize and respond to an infection) to CMV. This may help to reduce both CMV complications and reduce the need for antiviral drugs in patients undergoing a donor hematopoietic cell transplant.
Read the detailed description
PRIMARY OBJECTIVES:
- To evaluate the safety and tolerability of CMV-MVA Triplex (multi-peptide CMV-MVA vaccine) in vaccinated hematopoietic cell transplant (HCT) recipients by assessing the following: non-relapse mortality (NRM) at 100 days post HCT, severe (grade 3-4) acute graft-versus-host disease (GVHD) (aGVHD), and grade 3-4 adverse events (AEs) (Common Terminology Criteria for Adverse Events [CTCAE] 4.0) probably or definitely related to the vaccination within 2 weeks from each vaccination.
II. To determine if CMV-MVA Triplex reduces the frequency of CMV events defined as reactivation or CMV disease in allogeneic CMV positive HCT recipients (HCT-R+).
SECONDARY OBJECTIVES:
- To characterize CMV reactivation and CMV disease in recipients of CMV-MVA Triplex compared to placebo by assessing time-to viremia (defined as number of days from transplantation to the date of > 500 CMV gc/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 >= 1500 CMV gc/mL), cumulative number of CMV specific antiviral treatment days.
II. To evaluate the impact of CMV-MVA Triplex on transplant related outcomes by assessing the incidence of acute GVHD (aGVHD), chronic GVHD (cGVHD), relapse, non-relapse mortality, all-cause mortality, infections.
III. To determine 1) if CMV-MVA Triplex increases levels, function and kinetics of CMV-specific T cell immunity in vaccinated compared to placebo treated human leukocyte antigen (HLA) A*0201, CMV seropositive HCT-recipients, 2) to determine whether vaccination induces adaptive natural killer (NK) cell population changes, and increase in the highly cytotoxic memory killer cell lectin-like receptor subfamily C, member 2 (NKG2C)+ NK cells, and 3) to explore GVHD biomarkers and compare between the vaccine and placebo groups.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive multi-peptide CMV-MVA 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, patients are followed up for 1 year post-HCT.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cytomegalovirus (CMV) Events to Day 100
Cytomegalovirus (CMV) events included CMV reactivation ≥1250 CMV DNA IU/mL, CMV viremia prompting antiviral therapy, or CMV disease before day 100 after HCT.
Measured: Prior to day 100 post-HCT
Incidence of Severe (Grade 3-4) Acute Graft-Versus-Host Disease
Severe acute graft-versus-host disease (aGVHD, grade 3-4) was monitored as every 12th subject on the vaccine arm reaches the 100 day evaluation point. aGVHD was scored using Keystone consensus criteria [Przepiorka, D., et al., 1994 Consensus Conference on Acute GVHD Grading. Bone Marrow Transplant, 1995. 15(6): p. 825-8].
Measured: Up to 100 days post-transplant

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Laboratory Biomarker Analysis and Multi-peptide CMV-Modified Vaccinia Ankara Vaccine in people with Accelerated Phase Chronic Myelogenous Leukemia, BCR-ABL1 Positive and Acute Lymphoblastic Leukemia in Remission, run by City of Hope Medical Center at 3 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 28 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 14 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cytomegalovirus (CMV) Events to Day 100 (time frame: Prior to day 100 post-HCT). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02506933, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jul 2026.
