Viruses that kill bacteria: a new weapon against superbugs?
NCT ID NCT06368388
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
This study tests personalized phage therapy in people with serious infections that have not responded to antibiotics or surgery. Researchers will collect data before, during, and after treatment to see how safe and effective phage therapy is, and how it affects different body sites. They will also compare its costs to standard care and use machine learning to match phages to each person's infection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bacteriophages (viruses that kill bacteria)
- What this could lead to
- If phage therapy works, it could offer a new option for people with infections that resist antibiotics. It might also become a reimbursed treatment.
- What could go wrong
- Phage therapy is still experimental and not proven for these infections. The study is small and may not show clear benefits. Some people may have side effects or the therapy may not work for everyone.

Who is studied
All patients: * Diagnosed with an MSI or CRS or persistent bacteremia or or pulmonary infection (cystic fibrosis/bronchiectasis) or HS and * For whom all previous treatments (surgical and antibiotic) have failed or for whom no other treatment options are available (i.e., last resort cases, based on the assessment of the local phage hub), for example in case of bacterial resistance. And * Of whom the pathogen causative for the infection is one for which phages are available in the phage bank, and * Who have given informed consent to have their data collected in a patient registry.
