New drug aims to stop CMV from coming back after transplant
NCT ID NCT06407232
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether the drug letermovir can prevent cytomegalovirus (CMV) from coming back in kidney or kidney/pancreas transplant patients who are at high risk. About 90 adults will take letermovir daily for 84 days and be followed for 6 months. The goal is to see if it reduces the number of CMV flare-ups and the need for other treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Letermovir (Prevymis)
- What this could lead to
- If successful, letermovir could offer a new way to prevent CMV from coming back after treatment in transplant patients, reducing the need for other antiviral drugs.
- What could go wrong
- This is a phase 3 trial with only 90 participants, so results may not apply to everyone. Letermovir may not work as well as hoped, and side effects are possible.
