What this trial studies

This cohort study aims to document adverse events associated with the use of bacteriophages in treating serious infections, particularly prosthetic joint infections. It will collect data on potential serious adverse events from compassionate cases and classify them based on their relation to surgery, antibiotics, or phage therapy. Additionally, blood specimens will be biobanked before and after treatment to investigate any immunological responses related to phage therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with serious infections being treated with phage therapy at the CRIOAc Lyon.

Not a fit: Patients who are under guardianship, deprived of liberty, or pregnant/breastfeeding will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical safety data that may support the use of phage therapy as a viable treatment option for serious infections.

How similar studies have performed: While there is limited literature on the safety of phage therapy, this study represents a novel approach to understanding its adverse effects.
