Safety and Efficacy Study of Ceftolozane/Tazobactam to Treat Ventilated Nosocomial Pneumonia (MK-7625A-008)

Summary

This is a phase 3, multicenter, prospective, randomized study of intravenous (IV) ceftolozane/tazobactam versus IV meropenem in the treatment of adult participants with either ventilator-associated bacterial pneumonia (VABP) or ventilated hospital-acquired bacterial pneumonia (HABP). The primary objective is to demonstrate the non-inferiority of ceftolozane/tazobactam versus meropenem in adult participants with ventilated nosocomial pneumonia (VNP) based on the difference in Day 28 all-cause mortality rates in the Intent-to-treat (ITT) population using a non-inferiority margin of 10%.
