Kidney Failure

This phase III trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant. 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.

Approximately 150 patients with acute kidney injury (AKI) associated with acute hypoxemic respiratory failure (AHRF) will be randomized at up to 40 sites. Patients will be randomly assigned to either Auxora or matching placebo. Study drug infusions will occur every 24 hours for five consecutive days for a total of five infusions.
