What this trial studies

This study aims to evaluate the effectiveness of a single oral dose of 500mg azithromycin in eradicating nasopharyngeal carriage of Neisseria meningitidis among carriers. Azithromycin, a macrolide antibiotic, works by inhibiting bacterial protein synthesis and has shown broad-spectrum activity against various bacteria. The study is particularly relevant due to the rise of ciprofloxacin-resistant meningococcal strains, prompting a need for alternative prophylactic treatments. Participants will be undergraduate and graduate students from Emory University who are identified as carriers of the bacteria.

Who should consider this trial

Good fit: Ideal candidates for this study are undergraduate and graduate students at Emory University who reside in university-affiliated housing or off-campus housing and are identified as carriers of N. meningitidis.

Not a fit: Patients who are university faculty or staff, pregnant or breastfeeding, or have a history of allergic reactions to azithromycin will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide an effective alternative for eradicating meningococcal carriage, potentially reducing the incidence of invasive meningococcal disease.

How similar studies have performed: Previous studies have shown azithromycin to be effective against N. meningitidis, but this specific application for eradication in carriers is less well-studied, making it a novel approach.
