PF-5081090 (8.75, 75, 300 mg/kg; s.c.; single dose) exhibits a exposure increasing in linear manner across the dose range in mice, with area under the concentration-time curve (AUC) and maximum concentration of drug in serum (Cmax) increasing with a proportional increase in dose.
PF-5081090 shows potent efficacies against sentinel strains of P. aeruginosa and K. pneumonia in CD-1 mice, with effective dose (ED50) ranging from 7.4-55.9 mg/kg (against acute septicemia model), <25 mg/kg (against pneumonia model), and 16.8 mg/kg (against neutropenic thigh model) in mice infected with P. aeruginosa PA-1950.
