Arm Intervention/treatment
Experimental: Ceftolozane/tazobactam
ceftolozane/tazobactam IV 3000 mg (comprising 2000 mg ceftolozane and 1000 mg tazobactam) every 8 hours for 8-14 days, or 14 days for Pseudomonas aeruginosa.
Drug: ceftolozane/tazobactam
Ceftolozane/tazobactam is an antibacterial consisting of a co-formulation of ceftolozane, a novel antipseudomonal cephalosporin and tazobactam, a well-established beta(β)-lactamase inhibitor (BLI) being developed for the treatment of serious bacterial infections.
Active Comparator: meropenem
meropenem IV 1000 mg every 8 hours for 8-14 days, or 14 for Pseudomonas aeruginosa
Drug: Meropenem
Meropenem is a broad spectrum injectable antibiotic widely used to treat serious infections such as ventilator-associated bacterial pneumonia and hospital-acquired bacterial pneumonia.
Other Names:
  • Merofit
  • Monan
  • Meronem
  • Merrem

Primary Outcome Measures :
  1. All Cause Mortality [ Time Frame: Day 28 ]
    Intent-to-Treat (ITT) population

Secondary Outcome Measures :
  1. Clinical response rates at the TOC visit (ceftolozane/tazobactam versus meropenem) in the subset of subjects who had P. aeruginosa from the baseline lower respiratory tract culture [ Time Frame: TOC is 7-14 days after EOT ]
  2. Day 28 all-cause mortality rates of participants in the ceftolozane/tazobactam versus meropenem arms in the Microbiological Intent-to-Treat (mITT) population [ Time Frame: Day 28 ]
  3. Clinical response rates of ceftolozane/tazobactam versus meropenem in adult participants with ventilated nosocomial pneumonia (VNP) in the Microbiological Intent-to-Treat (mITT) population [ Time Frame: This will be assessed at the Test-of-cure (TOC) visit which is 7 to 14 days after the End of Therapy (EOT) visit ]
  4. Clinical response rates of ceftolozane/tazobactam versus meropenem in adult participants with VNP in the Intent-to-Treat (ITT) population [ Time Frame: This will be assessed at the Test-of-cure (TOC) visit which is 7 to 14 days after the End of Therapy (EOT) visit ]
  5. Clinical response rates of ceftolozane/tazobactam versus meropenem in adult participants with VNP in the Clinically Evaluable (CE) population [ Time Frame: This will be assessed at the Test-of-cure (TOC) visit which is 7 to 14 days after the End of Therapy (EOT) visit ]
