Clinical Trial Summary

This is an open-label, randomized, multi-center, interventional, active-controlled Phase 4 study to evaluate the efficacy and safety of CAZ-AVI versus BAT in the treatment of infected participants with selected infection types (Hospital Acquired Pneumonia [HAP] (including Ventilator-Associated Pneumonia [VAP]); Complicated Urinary-Tract Infection [cUTI]; Complicated Intra-Abdominal Infection [cIAI]; Bloodstream Infection [BSI]) due to carbapenem-resistant Gram-negative pathogens in China.This study will be an estimation study. The statistical inference will be based on point estimate and confidence interval.

• Participant who had received appropriate prior empiric antibacterial therapy for a carbapenem-resistant pathogen must meet at least 1 of the following criteria: no or no more than 24h; worsening of objective symptoms or signs after at least 48 hours of antibacterial therapy; no change of objective symptoms or signs after at least 72 hours of antibacterial therapy.

• Capable of giving signed informed consent
