About this study

This phase Ib trial tests the safety, side effects, and how well cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) Triplex vaccine works in enhancing CMV-specific immunity and preventing CMV viremia in patients undergoing haploidentical hematopoietic stem cell transplant. Haploidentical stem cell transplantation (haploHCT) has advanced to become the predominant procedure for patients lacking a matched donor. Compared to matched related donor transplants, the rate of significant CMV infection is higher in patients undergoing a haploHCT. Significant CMV infection is associated with an increased risk of complications and death. Vaccination is the main preventative approach to limit complications and death in immunocompromised patients at high risk of post-stem cell transplant infections. CMV-MVA Triplex vaccine, is a CMV vaccine based on the attenuated poxvirus, modified vaccinia Ankara (MVA), developed to enhance CMV-specific immunity in both healthy stem cell transplant donors and stem cell transplant patients to prevent significant CMV infection post-stem cell transplant. Giving CMV-MVA triplex vaccine may be safe, tolerable and/or effective in enhancing cytomegalovirus (CMV)-specific immunity and preventing CMV viremia in patients undergoing a haploHCT.
