NCT02019420

Brief Summary

This is a 1:1 ratio, randomized, double-blind, double-dummy, multicenter, global Phase 3 study of tedizolid phosphate (TR-701 FA) 200 mg intravenous (IV) once daily for 7 days versus linezolid (Zyvox®, Zyvoxid®, etc) 600 mg IV every 12 hours for 10 days for the treatment of ventilated participants with presumed gram-positive hospital-acquired bacterial pneumonia (HABP) or ventilator-associated bacterial pneumonia (VABP), collectively referred to as ventilated nosocomial pneumonia (VNP). Participants with concurrent gram-positive bacteremia are to receive 14 days of active therapy in either treatment arm. The primary objective is to determine the noninferiority (NI) in all-cause mortality (ACM) within 28 days after randomization of IV tedizolid phosphate compared with IV linezolid in the Intent to Treat (ITT) Analysis Set (NI is declared when the lower bound of the 95% CI \> -10).

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With All-Cause Mortality in the Intent-to-Treat (ITT) Population

    The numbers of participants with all-cause mortality within 28 days after randomization was determined in the ITT population. Any participants who were lost to follow-up and not known to be alive or deceased by Day 28 were imputed as deceased.

    Up to 28 days

Secondary Outcomes (11)

  • Number of Participants With All-Cause Mortality in the Microbiological Intent-to-Treat (mITT) Population

    Up to 28 days

  • Clinical Response at Test of Cure (TOC) Visit in the Intent-to-Treat (ITT) Population

    7-14 days after end of therapy - TOC

  • Clinical Response at Test of Cure (TOC) Visit in the Clinically-Evaluable (CE) Population

    7-14 days after end of therapy - TOC

  • Number of Methicillin-Susceptible Staphylococcus Aureus (MSSA)-Infected Participants With All-Cause Mortality in the Microbiological Intent-to-Treat (mITT) Population

    Up to 28 days

  • Number of Methicillin-Resistant Staphylococcus Aureus (MRSA)-Infected Participants With All-Cause Mortality in the Microbiological Intent-to-Treat (mITT) Population

    Up to 28 days

  • +6 more secondary outcomes
