Conditions

Complicated urinary tract infection (cUTI), acute uncomplicated pyelonephritis (AP), hospital acquired bacterial pneumonia (HABP), ventilator-associated bacterial pneumonia (VABP), and complicated intra-abdominal infection (cIAI)

Brief summary

The primary efficacy endpoint is the proportion of patients with overall treatment success at TOC across all infection types (ie, cUTI, AP, HABP, VABP, and cIAI), which is a composite endpoint derived from the efficacy outcomes of each infection type. This is the proportion of patients in the Microbiological CRE Modified Intent to-Treat (mCRE-MITT) Population with a treatment outcome of success.

Detailed description

Secondary efficacy endpoints across all infection types, for individual infection type and across all infection types, for cUTI/AP only, for HABP/VABP only, or cIAI only, for secondary bacteremia only are included in study protocol
