Summary
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).
