Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with a weight of at least 32 kg who have serum containing functional anti-Pseudomonas antibodies and are receiving care at Grenoble University Hospital.
✕Probably not a fit
Patients who are legally protected, such as minors, pregnant or nursing women, or those hospitalized under duress, will not benefit from this study.

What this trial studies
This study aims to isolate and produce therapeutic monoclonal antibodies targeting Pseudomonas aeruginosa, a pathogenic bacterium known for its multi-antibiotic resistance, particularly in hospital settings. By focusing on patients with existing functional anti-Pseudomonas antibodies, the study seeks to develop an alternative treatment option for infections caused by antibiotic-resistant strains. The approach involves collecting blood samples from eligible patients at Grenoble University Hospital to identify and isolate these antibodies for potential therapeutic use.
Why it matters
Potential benefit: If successful, this could provide a new treatment option for patients suffering from infections caused by antibiotic-resistant Pseudomonas aeruginosa.
How similar studies have gone: While the approach of using monoclonal antibodies is established, the specific application to Pseudomonas aeruginosa in this context is relatively novel and has not been extensively tested.
