Outcomes

Primary Outcome Measures

Number of Participants With at Least One Grade 2 (Moderate) or Higher Treatment-emergent Adverse Event
Adverse events include local and systemic reactions. All Grade 2 (moderate) adverse events were reported, regardless of relationship to study product. Number of participants with an AE are summarized by MedDRA system organ class (SOC). Each participant is only counted once per SOC.

Secondary Outcome Measures

Accumulation Ratio for AUC (Area Under the Plasma Concentration-time Curve of Study Drug) [RAUC]
Mean and standard deviation (SD) of the RAUC PK parameter were estimated for ceftazidime, avibactam, and/or aztreonam by dividing the AUC(0-8) (avibactam and ceftazidime) or AUC(0-6) (aztreonam) on Day 7 by the AUC(0-Tau) on Day 1. AUC(0-8) and AUC(0-6) (µg*hr/mL) on Day 7 and AUC(0-Tau) (µg*hr/mL) on Day 1 were estimated from plasma concentration-time data using Non-compartmental analysis with the linear trapezoidal linear interpolation method for AVYCAZ IV, ATM IV, AVYCAZ + ATM 1.5, and AVYCAZ + ATM 2.0.
Accumulation Ratio for Cmax (Maximum Plasma Concentration) (RCmax)
Mean and standard deviation (SD) of the RCmax PK parameter were estimated for ceftazidime, avibactam, and/or aztreonam by dividing the Cmax on Day 7 by the Cmax on Day 1. Cmax (ug/mL) was estimated from plasma concentration-time data using Non-compartmental analysis for AVYCAZ IV, ATM IV, AVYCAZ + ATM 1.5, and AVYCAZ + ATM 2.0.
Area Under the Plasma Concentration-time Curve of Study Drug From Time of Dosing Extrapolated to Infinity [AUC(0-Inf)]
Mean and standard deviation (SD) of the AUC(0-inf) (µg*hr/mL) PK parameter were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Area Under the Plasma Concentration-time Curve Data of Study Drug During the Dosing Interval on Day 1 [AUC(0-Tau)]
Mean and standard deviation (SD) of the AUC(0-Tau) (µg*hr/mL) PK parameter were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis using linear trapezoidal linear interpolation method for AVYCAZ IV, ATM IV, AVYCAZ + ATM 1.5, and AVYCAZ + ATM 2.0. AVYCAZ CI and ATM CI were not reported.
Incidence of Treatment-emergent Adverse Events, by System Organ Class (SOC) and Maximum Severity Level
Number of participants with an AE are summarized by MedDRA system organ class (SOC) and severity. Each participant is only counted once at the highest severity recorded. For clinical laboratory tests, mild abnormal laboratory values that were not, in the investigator's opinion, medically significant were not reported as adverse events.
Maximum Plasma Concentration of Study Drug After the First Dose (Cmax)
Mean and standard deviation (SD) of the Cmax (ug/mL) PK parameter after the first dose were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Maximum Plasma Concentration of Study Drug Following Multiple Daily Dosing (Cmax)
Mean and standard deviation (SD) of the Cmax (ug/mL) PK parameter following multiple daily dosing were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Minimum Plasma Concentration of Study Drug at the End of the Dosing Interval on Day 7 (Cmin)
Mean and standard deviation (SD) of the Cmin (ug/mL) PK parameter were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis for AVYCAZ IV, ATM IV, AVYCAZ + ATM 1.5, and AVYCAZ + ATM 2.0. Cmin was not provided on day 7 because it was the last dosage of the study product administered; Cmin was therefore not calculated for this terminal elimination profile since the minimum concentration after a final dose would only reflect the last time point after Cmax that a blood sample is obtained, or the assay's limit of quantitation. It is therefore not comparable to Cmin calculated on prior days.
Minimum Plasma Concentration of Study Drug Following Multiple Daily Dosing on Day 1 (Cmin)
Mean and standard deviation (SD) of the Cmin (ug/mL) PK parameter were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis for AVYCAZ IV, ATM IV, AVYCAZ + ATM 1.5, and AVYCAZ + ATM 2.0.
Renal Clearance of Study Drug (CLR)
Mean and standard deviation (SD) of the CLR (L/h) PK parameter were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma and urine concentration-time data using Non-compartmental analysis. Renal clearance was calculated as Ae(0-8)/AUC(0-8) for ceftazidime and avibactam and as AE(0-4)/AUC(0-4) for aztreonam where Ae(0-8) and Ae(0-4) are the amounts of study drug excreted into the urine from time of dosing to 8 or 4 h post-dose, respectively, and AUC(0-8) and AUC(0-4) are the areas under the plasma concentration-time curve from time of dosing to 8 or 4 h post-dose, respectively.
Concentration of Study Drug at Steady State After Continuous Infusion (Css)
Mean and standard deviation (SD) of the Css (ug/mL) PK parameter were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data for AVYCAZ CI and ATM CI.
Total Body Plasma Clearance of Study Drug (CL)
Mean and standard deviation (SD) of the CL (L/h) PK parameter were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Time of Cmax (Maximum Plasma Concentration) of Study Drug After the First Dose (Tmax)
Mean and standard deviation (SD) of the Tmax (h) PK parameter after the first dose were estimated from the Day 1 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Time to Cmax (Maximum Plasma Concentration) of Study Drug Following Multiple Daily Dosing (Tmax)
Mean and standard deviation (SD) of the Tmax (h) PK parameter following multiple daily dosing were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
Volume of Distribution of Study Drug at Steady-state Based on the Last Observed Concentration (Vss)
Mean and standard deviation (SD) of the Vss (L) PK parameter were estimated from the Day 7 ceftazidime, avibactam, and/or aztreonam plasma concentration-time data using Non-compartmental analysis.
