Isolation of therapeutic antibodies against Pseudomonas aeruginosa

Isolation of Human Recombinant Therapeutic Monoclonal Anti-Pseudomonas Antibodies From B Lymphocytes of Patients Who Have Been Followed for Infection or Colonization With Pseudomonas Aeruginosa: a Prospective Monocentric Trial

Observational University Hospital, Grenoble · NCT04335383

This study is trying to find new antibodies from patients to help treat infections caused by the tough-to-treat bacteria Pseudomonas aeruginosa.

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.

Who should consider this trial

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.

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.

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 performed: 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.
