Neutropenic murine thigh infection models (Enterobacterales, S. aureus); in vitro E. coli chemostat model
“The Applicant conducted several nonclinical PK-PD studies examining the effect of gepotidacin on Enterobacterales and Staphylococcus aureus in vivo (neutropenic murine thigh infection models) and Escherichia coli in vitro (1-compartment “chemostat” models).”

Reviewer's view of the efficacy data
FDA: murine thigh and chemostat PK-PD findings deemed unreliable for uUTI; chemostat ignores bladder architecture, urodynamics, urine pH
“the findings from both murine thigh infection model and in vitro 1-compartment (chemostat) model were deemed unreliable for assessing uUTI for the following reasons: 1) the in vitro 1- compartment model does not account for bladder tissue architecture, the complexities of urodynamics, or the pH of urine”
