An Open-label, Randomised, Non-inferiority Trial of the Efficacy and Safety of Ciprofloxacin Versus an Aminoglycoside Followed by Ciprofloxacin in the Treatment of Bubonic Plague
In Brief
A Phase 3 clinical trial evaluating Ciprofloxacin, Streptomycin, and 1 other intervention for Plague, Bubonic and Plague, Pneumonic. Completed, enrolled 222 participants across 1 site.
Detailed Summary
The primary objective of this trial is to test the hypothesis that ciprofloxacin monotherapy given (orally, intravenously, or combination) for 10 days is non-inferior to an aminoglycoside (given on days 1-3) followed by ciprofloxacin (given on days 4-10) in the treatment of bubonic plague. Secondary objectives are: \- to evaluate the level and kinetics of anti-Y. pestis antibodies of patients (bubonic and pneumonic plague) included in the study (anti-F1 ELISA techniques) at D1, D11, D21, M3 for patients who are positive at D21, and M12 for patients who are positive at M3. The tertiary objectives are: \- to evaluate the level and kinetics of the levels of anti-Y. pestis antibodies and circulating F1 antigen of the patients (bubonic and pneumonic plague) included in the study (Luminex MagPix techniques with a Multiplex containing anti-F1 and rLcrV antigens and an F1 antigen capture multiplex) at D1, D11, D21, M3 for patients positive at D21, and M12 for patients who are positive at M3. Observational non-comparative study of pneumonic plague * The primary objective is to document the efficacy and safety of the currently recommended combination therapy treatment of pneumonic plague - an aminoglycoside (streptomycin or gentamicin) and ciprofloxacin combination therapy. * The secondary and tertiary objectives of the bubonic plague trial also apply to the pneumonic plague cohort.

Timeline
Interventions
Adults: Ciprofloxacin 500mg orally twice daily (or 400mg IV twice daily for those who cannot take oral medication) for 10 days; Children:Ciprofloxacin 15mg/kg twice daily (max 500mg per dose) orally (or 10mg/kg IV twice daily for those who cannot take oral - maximum dose 400mg) for 10 days. Patients who begin intravenous therapy may switch to oral administration once they are able to swallow or once deemed clinically appropriate by the treating physician.
Adults: streptomycin 1g twice daily for three days, followed by ciprofloxacin 500mg orally twice daily (or ciprofloxacin 400mg twice daily by IV for those unable to take orally) for an additional 7 days. Children: streptomycin 15mg/kg twice daily for three days followed by ciprofloxacin 15mg/kg twice daily (max 500mg per dose) orally (or 10mg/kg IV twice daily for those who cannot take oral - maximum dose 400mg) for 7 additional days. Patients who begin intravenous therapy may switch to oral administration once they are able to swallow or once deemed clinically appropriate by the treating physician.
Adults: 2.5mg/kg IV gentamicin twice daily for 3 days followed by ciprofloxacin 500 mg orally twice daily (or ciprofloxacin 400 mg twice daily IV for those who cannot take oral) for a further 7 days. Children: 2.5mg/kg IV gentamicin twice daily for 3 days, followed by ciprofloxacin 15mg/kg (max 500mg per dose) orally (or 10mg/kg IV twice daily for those who cannot take the oral route) for a further 7 days.
