Clinical Trial Summary

This is a Phase I, open-label, non-randomized, single center study in 48 healthy adult male and female subjects, aged 18 to 45 years. This study is aimed to investigate the safety and pharmacokinetics of ceftazidime-avibactam (AVYCAZ) combined with aztreonam (ATM), AVYCAZ alone, and ATM alone. The study will have 6 arms, arms 1-4 are the single drug administration treatment groups and will include AVYCAZ per label dosing, AVYCAZ as a continuous infusion (CI), ATM per label dosing, and ATM as a CI. Arms 5 and 6 are the two AVYCAZ and ATM combination drug administration treatment groups. The duration of subject participation will be up to 44 days, and the total length of the study will be 15 months. The primary objective of this study is to describe the safety of two dosing regimens of AVYCAZ combined with ATM relative to AVYCAZ alone, and ATM alone in healthy adult subjects.

Outcome

Type Measure Description Time frame Safety issue
Primary 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. Day 1 through Day 11
Secondary 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. Day 1 and Day 7
Secondary 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. Day 1 and Day 7
Secondary 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. Day 7
Secondary 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. Day 1
Secondary 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. Day 1 through Day 14
Secondary 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. Day 1
Secondary 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. Day 7
Secondary 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. Day 7
Secondary 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. Day 1
Secondary 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. Day 1
Secondary 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. Day 1
Secondary 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. Day 7
Secondary 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. Day 1
Secondary 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. Day 7
Secondary 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. Day 7
