The dose of fosmidomycin, equivalent to 30mg/kg twice daily for three days, selected for evaluation in this proof of concept study is derived from the highest dose that was administered in the Phase I safety tolerance studies. While the recommended dose of azithromycin for the treatment of bacterial infections is 250mg daily for three days, higher doses of up to 1500mg daily for three days have been evaluated for the treatment of malaria, in combination with artesunate or quinine.
