New hope: drug may shield kids from virus after transplant

NCT ID NCT05711667

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study tests whether the antiviral drug letermovir can prevent cytomegalovirus (CMV) infection in children and teens who have had a stem cell transplant. About 105 participants aged 2 to 17 will receive letermovir and be monitored for 14 weeks. The goal is to see if the drug lowers the chance of serious CMV infection compared to expected rates without it.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Letermovir (an antiviral drug)

What this could lead to

If it works, this could provide a safe way to prevent CMV infection in children after stem cell transplant, reducing hospital stays and severe illness.

What could go wrong

This is a single-arm trial with no placebo group, so results may be less definitive. The drug may still fail to prevent CMV or cause side effects.
