A PHASE 3 PROSPECTIVE, RANDOMIZED, MULTICENTER, OPEN-LABEL, CENTRAL ASSESSOR-BLINDED, PARALLEL GROUP, COMPARATIVE STUDY TO DETERMINE THE EFFICACY, SAFETY AND TOLERABILITY OF AZTREONAM-AVIBACTAM (ATM-AVI) ±METRONIDAZOLE (MTZ) VERSUS MEROPENEM±COLISTIN (MER±COL) FOR THE TREATMENT OF SERIOUS INFECTIONS DUE TO GRAM NEGATIVE BACTERIA, INCLUDING METALLO-Β-LACTAMASE (MBL) - PRODUCING MULTIDRUG RESISTANT PATHOGENS, FOR WHICH THERE ARE LIMITED OR NO TREATMENT OPTIONS
In Brief
A Phase 3 clinical trial evaluating ATM-AVI, MTZ, and 2 other interventions for Complicated Intra-abdominal Infection and 2 related conditions. Completed, enrolled 422 participants across 157 sites in 21 countries.
Detailed Summary
A Phase 3 comparative study to determine the efficacy, safety and tolerability of Aztreonam-Avibactam (ATM-AVI) ± Metronidazole (MTZ) versus Meropenem (MER) ± Colistin (COL) for the treatment of serious infections due to Gram negative bacteria.
