Primary Outcome Measures
NameTimeMethod
Clinical Response at the Test-of-Cure (TOC) Assessment Within the Clinically Evaluable (CE) PopulationDay 3, Day 14 or last day of therapy (treatment duration was at least 5 days and up to 14 days), and TOC (14-21 days after the last dose of therapy)

The clinical response was to be determined by the investigator and was classified as 1 of the following: cure (relevant clinical signs and symptoms of infection at baseline disappeared or recovered to normal and relevant non microbiological results of laboratory tests returned to normal level or the resolution of signs and symptoms so that at no further therapy was required), failure (participant required additional surgical or radiologic intervention and/or received additional anti-infection therapy to cure the infection since administration of study drug until TOC; or death after study Day 2 due to the infection or a treatment related AE or discontinuation due to a treatment related AE or received greater than 120% of the prescribed number of investigational product doses), or indeterminate (lost to follow-up; or died within 2 days after the first dose of study drug for any reason; or died after study Day 2 but prior to the TOC assessment because of non infection related reasons).

Clinical Response at the TOC Assessment Within the Modified Intent-to-Treat (mITT) PopulationDay 3, Day 14 or last day of therapy (treatment duration was at least 5 days and up to 14 days), and TOC (14-21 days after the last dose of therapy)

The clinical response was to be determined by the investigator and was classified as 1 of the following: cure (relevant clinical signs and symptoms of infection at baseline disappeared or recovered to normal and relevant non microbiological results of laboratory tests returned to normal level or the resolution of signs and symptoms so that at no further therapy was required), failure (participant required additional surgical or radiologic intervention and/or received additional anti-infection therapy to cure the infection since administration of study drug until TOC; or death after study Day 2 due to the infection or a treatment related AE or discontinuation due to a treatment related AE or received greater than 120% of the prescribed number of investigational product doses), or indeterminate (lost to follow-up; or died within 2 days after the first dose of study drug for any reason; or died after study Day 2 but prior to the TOC assessment because of non infection related reasons).

Secondary Outcome Measures
NameTimeMethod
Clinical Response at the TOC Assessment Within the Microbiologically Evaluable (ME) PopulationDay 3, Day 14 or last day of therapy (treatment duration was at least 5 days and up to 14 days), and TOC (14-21 days after the last dose of therapy)

The clinical response was to be determined by the investigator and was classified as 1 of the following: cure (relevant clinical signs and symptoms of infection at baseline disappeared or recovered to normal and relevant non microbiological results of laboratory tests returned to normal level or the resolution of signs and symptoms so that at no further therapy was required), failure (participant required additional surgical or radiologic intervention and/or received additional anti-infection therapy to cure the infection since administration of study drug until TOC; or death after study Day 2 due to the infection or a treatment related AE or discontinuation due to a treatment related AE or received greater than 120% of the prescribed number of investigational product doses), or indeterminate (lost to follow-up; or died within 2 days after the first dose of study drug for any reason; or died after study Day 2 but prior to the TOC assessment because of non infection related reasons).

Microbiological Response at the Subject Level in the ME Population at the TOC AssessmentDay 3, Day 14 or last day of therapy (treatment duration was at least 5 days and up to 14 days), and TOC (14-21 days after the last dose of therapy)

The microbiological response at the subject level was described according to the following definitions of efficacy. Eradication (documented or presumed): none of the baseline pathogens were present in repeat intra-abdominal cultures from the original site of infection taken during the study or a clinical response of cure precluded the necessity of a repeat intra-abdominal culture. Persistence (documented or presumed): documented: any baseline intra-abdominal pathogen was present in the cultures obtained from the original site of the intra-abdominal abscess, peritonitis, or surgical wound infection during the study; Presumed: repeat microbiological data were not obtained for a participant with a clinical response of failure. Superinfection: Emergence of a new pathogen during therapy, at the site of infection with emergence or worsening of clinical signs and symptoms of infection.
