New strategy aims to shield myeloma patients from dangerous virus during treatment

NCT ID NCT06920251

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether the antiviral drug letermovir can prevent a common and serious viral infection called CMV in people with relapsed/refractory multiple myeloma who are receiving the immunotherapy elranatamab. The trial will enroll 40 adults who are CMV-positive. Researchers will monitor how many patients develop a significant CMV infection during treatment. If letermovir works, it could become a standard preventive measure for these patients.

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) and elranatamab (a cancer immunotherapy)
What this could lead to
If successful, this could provide a way to prevent a serious viral infection (CMV) in multiple myeloma patients undergoing treatment, reducing hospitalizations and complications.
What could go wrong
This is a small, early-phase study with only 40 participants, so results may not apply to all patients. The drug may not effectively prevent CMV or could cause side effects.
