Summary

Phase 3 study to determine the efficacy, safety, and tolerability of aztreonam- avibactam (ATM- AVI) versus best available therapy (BAT) in the treatment of hospitalized adults with complicated intra-abdominal infections (cIAI), nosocomial pneumonia (NP) including hospital acquired pneumonia (HAP) and ventilator associated pneumonia (VAP), complicated urinary tract infections (cUTI), or bloodstream infections (BSI) due to metallo-β-lactamase (MBL)- producing Gram-negative bacteria.

Conditions

  • Serious Bacterial Infection

Interventions

COMBINATION_PRODUCT

ATM-AVI

ATM-AVI doses (loading, extended loading and maintenance) and the dosing frequency of the maintenance dose are dependent on renal function. Subjects will be given a loading dose of 500 mg ATM plus 167 mg AVI or 675 mg ATM plus 225 mg AVI over a period of 30 minutes. This treatment will immediately be followed by an extended loading dose of 1500 mg ATM plus 500 mg AVI or 675 mg ATM plus 225 mg AVI over a period of 3 hours. Then there will be a 3 hour or 5 hour gap. Subjects will receive a maintenance dose of 1500 mg ATM plus 500 mg AVI every 6 hours or 750 mg ATM plus 250 mg AVI every 6 hours, or 675 mg ATM plus 225 mg AVI every 8 hours. Subjects with cIAI will also receive Metronidazole (MTZ) 500 mg IV q8h over 60 minutes. The first dose of MTZ will be started immediately after the extended loading dose of ATM-AVI has completed and treatment will be continued until the end of the treatment period.

DRUG

BAT

The comparator treatment in this study is best available therapy (BAT) based upon site practice and local epidemiology. The choice of BAT (monotherapy or combination) for each subject must be recorded prior to randomization. If the chosen BAT does not provide adequate anaerobic coverage for cIAI subjects MTZ is to be administered as a co therapy. BAT dose, frequency, dose adjustments with renal impairment will be based on per local package inserts.
