Letermovir for Prevention of Cytomegalovirus Reactivation in Haploidentical and Mismatched Adult Donor Allogeneic Hematopoietic Cell Transplantation with Post-Transplantation Cyclophosphamide for Graft-versus-Host Disease Prophylaxis.

ABSTRACT: Cytomegalovirus (CMV) is serious viral infection in allogeneic hematopoietic cell transplantation (allo-HCT) recipients. November 2017, the novel CMV DNA terminase complex inhibitor letermovir was approved for prophylaxis of CMV infection in CMV-seropositive allo-HCT recipients. Here we sought to determine the effectiveness of letermovir in preventing CMV infection in CMV-seropositive patients undergoing haploidentical or mismatched adult unrelated donor allo-HCT using post-transplantation cyclophosphamide-based graft-versus host-disease prophylaxis. Sixty-four patients underwent transplantation between 2014 and 2019, of whom 32 received letermovir and 32 did not receive letermovir. The day 180 cumulative incidence of CMV infection requiring therapy was 45.3% (95% confidence interval [CI],
