  Purpose

This is a randomized, double-blind, double dummy, multicenter Phase 3 study of oral TR-701 FA 200 mg once daily for 6 days versus oral Zyvox® (linezolid) 600 mg every 12 hours for 10 days for the treatment of ABSSSI in adults.

Approximately 75 to 100 sites globally will participate in this study. Patients with an ABSSSI caused by suspected or documented gram positive pathogen(s) at baseline will be randomized 1:1 to study treatment
