Transplant patients at risk of Drug-Resistant virus under microscope
NCT ID NCT05234723
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is looking at 100 adult patients who have had an organ or stem cell transplant and later developed a CMV infection that is resistant or hard to treat with standard antiviral drugs. Researchers want to find out how common this problem is and what factors make it more likely. The goal is to use this information to design better ways to prevent and manage these tough infections in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help doctors identify which transplant patients are at highest risk for drug-resistant CMV, leading to better prevention and treatment strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly test any new drug or therapy, and results may not lead to immediate changes in patient care.

Who is studied
All adult (≥ 18 years) patients who underwent SOT or HSCT developing CMV-infection treated with GC/VGC during the study period will be screened for inclusion according to inclusion and exclusion criteria. Eligible patients will be classified as cases or controls according to the following definitions: * Case: SOT or HSCT recipients with genotypically confirmed GCV-RR CMV-event; * Control: SOT or HSCT recipients with "presumed" GCV-S CMV-event on the basis of good microbiological and clinical response to standard GCV/VGC treatment.
