Summary
"This trial aims to see if giving letermovir before stem cell transplant can help reduce the chances of getting a virus called cytomegalovirus in children and teenagers. The treatments before a stem
Who is the study for?
This trial is for children and teens (2-18 years old) who weigh at least 18 kg, are CMV sero-positive, and are planning to have a stem cell transplant. They must be healthy enough for the procedure (Lansky/Karnofsky scores > 50), not need dialysis, and have acceptable liver function tests.
What is being tested?
The study is testing if Letermovir can prevent cytomegalovirus infection in pediatric patients after a stem cell transplant. The drug aims to stop the virus from multiplying, potentially preventing or lessening the severity of infections.
What are the potential side effects?
Possible side effects of Letermovir include gastrointestinal symptoms like nausea and vomiting, potential liver enzyme elevation, headaches, coughing, fatigue, and an increased risk of other infections.
