Official Title: A Randomized, Non-inferiority, Active Controlled Clinical Trial to Evaluate the Safety and Efficacy of Ciprofloxacin Versus Doxycycline in the Treatment of Plague in Human
Brief Summary:
Plague is a severe, life-threatening disease. Plague occurs in focal locations worldwide, but over 95% of human cases reported to WHO are by countries in Africa. The most common clinical manifestations of human infection are bubonic, septicemic, and pneumonic plague. Untreated pneumonic or septicemic plague is fatal in over 90% of cases; untreated bubonic plague is fatal in over 50% of cases. Delayed and ineffectual treatment is a main contributor to elevated case fatality rates, which can be as high as 40%, and to the development of pneumonic plague and plague outbreaks.
Streptomycin is considered the treatment of choice, and prompt administration can reduce mortality to 5% or less. However, streptomycin may cause irreversible hearing loss and vestibular damage, reversible renal damage, and it is contraindicated during pregnancy. Tetracyclines, including doxycycline, are considered effective alternatives but they are bacteriostatic and relatively contraindicated for use in children aged < 8 years and pregnant women.
Ciprofloxacin is a relatively newer antimicrobial that is used extensively in clinical practice because of its broad-spectrum antimicrobial activity, excellent tissue and intracellular penetration, suitability for oral administration, and good overall tolerability. In vitro and animal studies suggest equivalent or greater activity of ciprofloxacin against Yersinia pestis when compared with streptomycin or tetracyclines. However, the efficacy of ciprofloxacin for the treatment of human plague has never been demonstrated, nor is it FDA approved for this indication.
Since 2004, CDC has collaborated with the Uganda Ministry of Health (MoH) and the Uganda Virus Research Institute (UVRI) to enhance surveillance, diagnosis, and ecological control of plague in Arua
