Primary Endpoint for EMA
The primary efficacy endpoint for this study for the European Medicines
Agency (EMA) will be the proportion of subjects in the co-primary m-
MITT and ME Populations who achieve a microbiologic outcome of Eradication at the TOC visit.
A microbiologic outcome of Eradication is defined as the demonstration
that the bacterial pathogen(s) found at baseline is reduced to <103
CFU/mL of urine.
