Primary Outcome Measures

Name	Time	Method
Percentage of Patients Who Attained Microbiological Eradication (MBE) at the Test of Cure (TOC) Visit in the Microbiological Intent to Treat (MITT) Population	Day 1 to TOC (Day 12)	MBE was defined as documented eradication of all isolated pathogens. This was based on a urine culture, taken at the TOC visit that showed that all pathogens isolated at baseline at ≥10\^5 colony forming unit(s) per milliliter (CFU/mL) were reduced to \<10\^4 CFU/mL.
Percentage of Patients Who Attained MBE at the TOC Visit in the Microbiologically Evaluable (ME) Population	Day 1 to TOC (Day 12)	MBE was defined as documented eradication of all isolated pathogens. This was based on a urine culture, taken at the TOC visit that showed that all pathogens isolated at baseline at ≥10\^5 CFU/mL were reduced to \<10\^4 CFU/mL.
Percentage of Patients With Treatment-Emergent Adverse Events (TEAE)	Day 1 to the end of study (Day 40)	An adverse event (AE) is any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered to be drug related. An AE (also referred to as an adverse experience) can be any unfavorable and unintended sign (eg, an abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, and it does not imply any judgment about causality. Adverse events also include the exacerbation or worsening of a condition present at screening other than the index infection for which the patient was enrolled in the study. A TEAE is any AE that newly appeared, increased in frequency, or worsened in severity following initiation of study drug.

Secondary Outcome Measures

Name	Time	Method
Time (Days) to Defervescense in the MITT Population	Day 1 to End of Study (Day 40)	Defervescence is defined as the absence of fever \<37.7 degrees Celsius and is assessed in patients who were afebrile at baseline.
Percentage of Patients Who Attained Clinical Cure Based on Investigator and Sponsor Assessments at TOC Visit in the Intent-to-treat (ITT) Population	Day 1 to TOC (Day 12)	Investigator's assessment criteria defined Clinical Cure as resolution of baseline clinical signs and symptoms of infection through the TOC visit.; The sponsor's assessment criteria was programmatically based on the investigator's assessment of participant clinical outcome, the number of days and doses of drug received and whether an antibiotic was administered.
Time (Days) to Clinical Cure Based on Investigator's and Sponsor's Assessments in the MITT Population	Day 1 to End of Study (Day 40)	Investigator's assessment criteria defined Clinical Cure as a resolution of baseline clinical signs and symptoms of infection through the TOC visit.; The Sponsor's assessment criteria was programmatically based on the investigator's assessment of participant clinical outcome, the number of days and doses of drug received and whether an antibiotic was administered.

Percentage of Patients Who Attained Clinical Cure Based on Investigator and Sponsor Assessments at the End of Treatment (EOT) Visit in the CE Population	Day 1 to EOT (Day 5)	Investigator's assessment criteria defined Clinical Cure as a resolution of baseline clinical signs and symptoms of infection through the EOT visit.; The Sponsor's assessment criteria was programmatically based on the investigator's assessment of participant clinical outcome, the number of days and doses of drug received and whether an antibiotic was administered.
Percentage of Patients Who Attained MBE at the EOT Visit in the ME Population	Day 1 to EOT (Day 5)	MBE was defined as documented eradication of all isolated pathogens.

Percentage of Patients Who Attained MBE at the EOT Visit in the MITT Population	Day 1 to EOT (Day 5)	MBE was defined as documented eradication of all isolated pathogens.

Percentage of Patients Who Attained MBE at the TOC Visit in the ME Population Stratified by Infection Category	Day 1 to TOC (Day 12)	MBE was defined as documented eradication of all isolated pathogens. This was based on a urine culture, taken at the TOC visit that showed that all pathogens isolated at baseline at ≥10\^5 CFU/mL were reduced to \<10\^4 CFU/mL.
Percentage of Patients Who Attained MBE at the TOC Visit in the ME Population by Country/Region	Day 1 to TOC (Day 12)	MBE was defined as documented eradication of all isolated pathogens. This was based on a urine culture, taken at the TOC visit that showed that all pathogens isolated at baseline at ≥10\^5 CFU/mL were reduced to \<10\^4 CFU/mL.
Time (Days) to Resolution of Signs and Symptoms of cUTI and AP in the MITT Population	Day 1 to End of Study (Day 40)	Resolution of clinical signs and symptoms is defined as absence of all signs and symptoms present at baseline.

Percentage of Patients With a Superinfection or New Infection in the ME Population	Day 1 to to End of Study (Day 40)	Superinfections are defined as a pathogen other than the one at baseline found in urine at ≥10\^5 CFU/mL any time after the first infusion through EOT. New infections are defined as a pathogen other than the one at baseline found in urine at ≥10\^5 CFU/mL any time after EOT.
