PHASE2

CMV-MVA Triplex Vaccination in HLA-Matched Related Stem Cell Donors for the Prevention of CMV Infection in Patients Undergoing Hematopoietic Stem Cell Transplant

Sponsor: City of Hope Medical Center

View on ClinicalTrials.gov

Summary

This phase II clinical trial tests how well the cytomegalovirus-modified vaccinica Ankara (CMV-MVA) Triplex vaccine given to human leukocyte antigens (HLA) matched related stem cell donors works to prevent cytomegalovirus (CMV) infection in patients undergoing hematopoietic stem cell transplant. The CMV-MVA Triplex vaccine works by causing an immune response in the donors body to the CMV virus, creating immunity to it. The donor then passes that immunity on to the patient upon receiving the stem cell transplant. Giving the CMV-MVA triplex vaccine to donors may help prevent CMV infection of patients undergoing stem cell transplantation.

Official title: Placebo-Controlled and Randomized Phase 2 Trial of CMV-MVA Triplex Vaccination in HLA-Matched Related Stem Cell Donors to Enhance CMV-Specific Immunity and Prevent CMV Viremia in Recipients After Hematopoietic Stem Cell Transplant
