Summary

This study tests whether a CMV-specific T cell immunity test can help doctors decide how long to give letermovir to prevent late CMV infection after a stem cell transplant. About 250 adults with blood cancers who had a first transplant will take part. The goal is to see if using the test reduces late CMV infections compared to standard care.

What this could mean

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

Active substance
Letermovir
What this could lead to
If successful, this could show that using an immunity test to personalize letermovir treatment reduces late CMV infections after stem cell transplants.
What could go wrong
This is a Phase 3 trial, but it is still early to know if the approach works better than standard care. The test may not accurately predict infection risk for all patients.
