Abstract
We describe the in vivo efficacy of human-simulated WCK 5222 (cefepime-zidebactam) exposure against multidrug-resistant Pseudomonas aeruginosa (meropenem MICs 8 to >256 μg/ml) in a neutropenic murine thigh infection model. WCK 5222 MICs ranged from 4 to 32 μg/ml. Substantial in vivo WCK 5222 activity was observed against all isolates, further enhancing the efficacy of zidebactam alone in 11/16 isolates (WCK 5222 mean reduction, –1.62 ± 0.58 log10 CFU/thigh), and a lack of activity was observed with cefepime monotherapy.Keywords
