Murine thigh and lung infection models with Gram-negative strains (dose-ranging, PK/PD target)
“Cefiderocol with ascending doses (0.3-30 mg/kg q3h) was tested in murine thigh and lung infection models for each tested strain to determine the effective dose and %fT > MIC required to achieve static effect and 1-log10 reduction in the number of viable cells compared to the mean of untreated baseline control group.”

Why that model
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Reviewer's view of the efficacy data
FDA: stasis or 1-log10 reduction in animal infection models considered sufficient to translate to clinical efficacy for cUTI
“For cUTI indication, bacteriostasis or 1-log10 bacteria reduction from the animal infection models is thought to be sufficient to translate the preclinical drug activity to clinical efficacy.”
