Biomarkers linked to response to phage treatment for nontuberculous mycobacterial and other infections

A Single-Center Observational Biomarker Investigation of Response to Bacteriophage Treatment for Bacterial Infection

NYU Langone Health · NCT07076238

This project will test whether blood and airway biomarkers can show which adults with refractory nontuberculous mycobacterial or other bacterial infections respond to bacteriophage treatment.

What this trial studies

This is an observational study enrolling adults with bacterial or mycobacterial infections who are being considered for bacteriophage therapy. Blood and airway samples will be collected at follow-up visits and analyzed for changes in the airway microbiome, host transcriptome, inflammatory cytokines, and development of neutralizing antibodies to phages. Samples from patients who receive phage therapy will be compared with samples from those who do not receive phage therapy. The primary goal is to identify biomarkers associated with clinical, radiographic, or culture improvement after at least 6–8 weeks of bacteriophage treatment.

Who should consider this trial

Good fit: Adults (18+) with confirmed bacterial or nontuberculous mycobacterial infections who are being considered by their clinician for phage therapy and can provide consent and attend study visits are ideal candidates.

Not a fit: Pregnant or breastfeeding individuals, patients under 18, and people whose infections are not being considered for phage therapy are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help predict which patients are likely to benefit from phage therapy and guide treatment decisions.

How similar studies have performed: Case reports and small series have shown promising results for phage therapy in refractory bacterial infections, but using biomarkers to predict response remains largely untested.
