Number of Participants With Abnormal Electrocardiogram (ECG) Findings

Twelve lead ECGs were obtained during the study using an ECG machine that automatically measured PR, QRS, QT, and QT corrected by Bazett's formula (QTcB), QT corrected by Fridericia's formula (QTcF) intervals. Twelve lead ECGs were performed with the participant in a semi-supine position having rested in this position for at least 10 minutes beforehand. Measurements that deviated substantially from previous readings were repeated immediately. Three measurements were taken at pre-dose on Day 1 at least 5 min apart. One additional ECG measurement was taken after completion of the first infusion of study medication. Two ECG measurements (pre and post-1st infusion of the day) were taken on Day 4 while the participant was on IV therapy. When there was an abnormal finding, two more were taken and the mean PR interval, QRS duration, QT interval and QTcB were calculated from automated ECG readings. One ECG measurement was taken at the early safety follow-up visit. (NCT01381549)

Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE)

AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse or misuse. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant.

Clinical response was a combination of clinical success and clinical failure. In clinical success, participants showed no signs and symptoms of pyelonephritis and lower complicated urinary tract infection and antibiotics are not used for the same. In clinical failure, there is reappearance of signs and symptoms of and lower complicated urinary tract infection and participant required antibiotics for the same. (NCT01381549)

Increase in the uropathogens in the urine culture and pathogens identified in the blood culture or use of antibacterials other than study treatments were classified as microbiological failures.

Therapeutic Response (Combined Clinical and Microbiological Response) at the End of IV Visit and Late Follow-Up Visit

The therapeutic response was the combination of a participant's clinical and microbiological response. It was assessed at the Test of Cure visit in participants who have a qualifying Gram-negative uropathogen at Baseline and have had a minimum of 5 days of IV therapy. Therapeutic response was a measure of the overall efficacy response, and a therapeutic success referred to participants who have been deemed both a 'clinical success' and a 'microbiological success'. All other combinations (other than 'clinical success' + 'microbiological success') were deemed failures for therapeutic response. (NCT01381549)

Clinical Response at the TOC Assessment Within the Modified Intent-to-Treat (mITT) Population

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). (NCT01721408)
Timeframe: Day 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)

Microbiological Response at the Subject Level in the ME Population at the TOC Assessment

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. (NCT01721408)

FOR was determined based on clinically relevant outcomes for the primary site of infection as follows: HABP/VABP: survival through Day 28; cIAI: favorable clinical response (all pretherapy symptoms of index infection resolved with no evidence of resurgence, no additional antibiotic therapy required, and no unplanned surgical or percutaneous drainage procedures) at Day 28; cUTI: favorable composite clinical response (all pretherapy symptoms of index infection resolved with no evidence of resurgence, no additional antibiotic therapy required) and microbiological response (urine culture shows sustained eradication of the baseline uropathogen [e.g., ≥10^5 CFU/mL at study entry is reduced to <10^4 CFU/mL]) at Early Follow-up (EFU). (NCT02452047)
Timeframe: Up to Day 30 (up to 9 days after completing study treatment)

Percentage of Participants With FCR at EFU

"The percentage of participants with FCR at EFU was determined for Groups 1 and 2. FCR at EFU was defined as sustained cure or cure. Sustained cure (for participants with cure response at the prior visit) was defined as all pretherapy signs and symptoms of index infection resolved with no evidence of resurgence and no additional antibiotic therapy required, and (for cIAI participants) no unplanned surgical procedures or percutaneous drainage procedures have been performed. Cure (for participants with improved response at EOT visit) was defined as all pretherapy signs and symptoms of index infection resolved or returned to preinfection status, and no additional IV antibiotic therapy required, and (for cIAI participants) no unplanned surgical procedures or percutaneous drainage procedures performed."
