Study Endpoints
Primary Endpoints
Clinical Response at the Test of Cure (TOC) Visit in the Microbiologically Modified Intent-To-Treat (mMITT) Analysis Set (Primary Outcome for FDA).
TOC: 28 to 35 days after start of study drug

The number of patients meeting the cure criteria: complete resolution or significant improvement of signs and symptoms of the index infection such that no further antibacterial therapy, drainage, or surgical intervention is necessary. Indeterminate response are where study data were not available for evaluation of efficacy for any reason, including patient lost to follow-up or assessment not undertaken such that a determination of clinical response could not be made, death where cIAI was clearly noncontributory or circumstances that precluded classification as a cure or failure. Results from two identical protocols D4280C00001 and D4280C00005 combined into a single database with agreement from FDA and EMA.
