Study Endpoints
Primary Endpoints
Total Daily Area Under the Plasma Concentration-time Profile From Time 0 to 24 Hours at Steady-state (AUC0-24,ss) of Aztreonam (ATM)
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.

AUC0-24,ss of ATM in Cohort 1 was calculated by 4\*AUC0-tau (tau = 6 hours), where AUC0-tau was area under the concentration-time profile from time 0 to time tau (the dosing interval). AUC0-24,ss of ATM in Cohort 2 was calculated by 3\*AUC0-tau (tau = 8 hours), where AUC0-tau was area under the plasma concentration-time profile from time 0 to time tau (the dosing interval).

Maximum Plasma Concentration (Cmax) of ATM
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.

The Cmax of ATM was observed directly from data.

AUC0-24,ss of Avibactam (AVI)
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.

AUC0-24,ss of AVI in Cohort 1 was calculated by 4\*AUC0-tau (tau = 6 hours), where AUC0-tau was area under the concentration-time profile from time 0 to time tau (the dosing interval). AUC0-24,ss of AVI in Cohort 2 was calculated by 3\*AUC0-tau (tau = 8 hours), where AUC0-tau was area under the plasma concentration-time profile from time 0 to time tau (the dosing interval).

Cmax of AVI
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.

The Cmax of AVI was observed directly from data.

Secondary Endpoints
Area Under the Plasma Concentration-time Profile From Time 0 to Time Tau (The Dosing Interval)(AUC0-tau) of ATM
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.
Time for Cmax (Tmax) of ATM
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.
Observed Plasma Concentration at the End of the Dosing Interval (Tau) (Ctau) of ATM
Predose, 2, 3, 3.25, 3.5, 3.75, 4, 5, 6, 8, 12, 16, and 24 hours after start of a maintenance dose infusion on Day 3.
