A Study of the Drug Letermovir as Prevention of Cytomegalovirus Infection After Stem Cell Transplant in Pediatric Patients (NCT05711667)

Letermovir Prophylaxis for Cytomegalovirus in Pediatric Hematopoietic Cell Transplantation

๐ŸŸข Recruiting Phase3 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Children's Oncology Group

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This phase III single arm trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant compared to estimated rate of infection without prophylaxis. The treatments used to prepare for HCT reduce the body's natural infection-fighting ability and increase the likelihood of an infection with a virus called cytomegalovirus. "Prophylaxis" means to take a drug to prevent a disease or side effect. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.
