The FDA has approved letermovir (Prevymis) to prevent cytomegalovirus (CMV) infection in adult CMV-seropositive patients treated with an allogeneic hematopoietic stem cell transplant (HSCT), based on a significant reduction in CMV infection rates in a phase III study.
Letermovir is a non-nucleoside CMV inhibitor that targets the viral terminase complex to prevent replication. Merck plans to make the medication available in December 2017 at a list price of 5.00 for a tablet version and 0.00 for an injection formulation.
