- Primary Outcome Measures
Name Time Method Percentage of Participants With Any Adverse Events (AEs) Up to 31 days An AE was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants experiencing any AE was reported for each arm.
Percentage of Participants With Any Serious AEs (SAEs) Up to 31 days An SAE was defined as any untoward medical consequence that, at any dose, results in death, is life-threatening, requires inpatient hospitalization or prolongs existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or any other important medical event. The percentage of participants with any SAE was reported for each arm.
Percentage of Participants With Any Drug-related AEs Up to 31 days A drug-related AE was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, and considered related to the study intervention. The percentage of participants with any drug related AEs was reported for each arm.
Percentage of Participants With Any Drug-related SAEs Up to 31 days A drug-related SAE was defined any untoward medical consequence that, at any dose, results in death, is life-threatening, requires inpatient hospitalization or prolongs existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or any other important medical event, that is considered related to the study intervention. The percentage of participants with any drug related SAEs was reported for each arm.
Percentage of Participants With AEs Leading to Discontinuation of Study Intervention Up to 14 days An AE was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with AEs leading to discontinuation of study intervention was reported for each arm.
- Secondary Outcome Measures
Name Time Method Plasma Concentrations of Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion The plasma concentrations of ceftolozane were determined in each group. Blood samples were collected at pre-specified timepoints to determine the plasma concentrations of ceftolozane in participants receiving ceftolozane/tazobactam.
Area Under the Concentration-time Curve of an 8-hour Dosing Interval (AUC0-8) of Plasma Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion AUC0-8 was defined as a measure of ceftolozane exposure that was calculated as the product of plasma drug concentration and time. Blood samples were collected at pre-specified timepoints to determine the AUC0-8 of ceftolozane in participants receiving ceftolozane/tazobactam.
Maximum Observed Concentration During a Dosage Interval (Cmax) of Plasma Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Cmax was defined as the maximum concentration of ceftolozane observed in plasma. Blood samples were collected at pre-specified timepoints to determine the Cmax of ceftolozane in participants receiving ceftolozane/tazobactam.
Elimination Half-life (t1/2) of Plasma Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Elimination half-life (t1/2) was defined as the time needed to reduce the level of ceftolozane in the blood by one-half (1/2). Blood samples collected at pre-specified timepoints were used to determine the apparent terminal half-life (t1/2) of ceftolozane in participants receiving ceftolozane/tazobactam.
Clearance (CL) of Plasma Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion CL was defined as the total clearance of ceftolozane in plasma over time, assessed as the rate at which ceftolozane was removed from the plasma. Blood samples were collected at pre-specified timepoints to determine the CL of ceftolozane in participants receiving ceftolozane/tazobactam.
Volume of Distribution (Vd) of Plasma Ceftolozane Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Vd was defined as the distributed volume of study drug in plasma at steady state. It is the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of the drug. Blood samples were collected at pre-specified timepoints to determine the Vd of ceftolozane in participants receiving ceftolozane/tazobactam.
Plasma Concentrations of Tazobactam Day 3: 1, between 4-5, and between 7-8 hours post start of infusion The plasma concentrations of tazobactam were determined in each group. Blood samples were collected at pre-specified timepoints to determine the plasma concentrations of tazobactam in participants receiving ceftolozane/tazobactam. No data were calculated for a timepoint if \>50% of samples were below limit of quantification (BLOQ).

Blood samples were collected at pre-specified timepoints to determine the AUC0-8 of tazobactam in participants receiving ceftolozane/tazobactam.
Maximum Observed Concentration During a Dosage Interval (Cmax) of Plasma Tazobactam Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Cmax was defined as the maximum concentration of tazobactam observed in plasma. Blood samples were collected at pre-specified timepoints to determine the Cmax of tazobactam in participants receiving ceftolozane/tazobactam. The analysis population consisted of participants who received at least 6 doses of ceftolozane/tazobactam and had at least 1 quantifiable plasma concentration of tazobactam.
Elimination Half-life (t1/2) of Plasma Tazobactam Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Elimination half-life (t1/2) was defined as the time needed to reduce the level of tazobactam in the blood by one-half (1/2). Blood samples collected at pre-specified timepoints were used to determine the apparent terminal half-life (t1/2) of tazobactam in participants receiving ceftolozane/tazobactam.
Clearance (CL) of Plasma Tazobactam Day 3: 1, between 4-5, and between 7-8 hours post start of infusion CL was defined as the total clearance of tazobactam in plasma over time, assessed as the rate at which tazobactam was removed from the plasma. Blood samples were collected at pre-specified timepoints to determine the CL of tazobactam in participants receiving ceftolozane/tazobactam.
Volume of Distribution (Vd) of Plasma Tazobactam Day 3: 1, between 4-5, and between 7-8 hours post start of infusion Vd is defined as the distributed volume of study drug in plasma at steady state. It is the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of the drug.
