  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

Primary Outcome Measures:
  • To determine noninferiority (NI) in the early clinical response rate [ Time Frame: 48-72 hours ] [ Designated as safety issue: No ]
    To determine the noninferiority (NI) in the early clinical response rate of 6-day oral TR-701 free acid (FA) compared with that of 10-day oral linezolid treatment at 48-72 hours in the Intent-to-Treat (ITT) analysis set in patients with acute bacterial skin and skin structure infections (ABSSSI)


Secondary Outcome Measures:
  • To compare the clinical response of 6-day TR-701 FA and 10-day linezolid treatment at 48-72 hours that is sustained at the End of Therapy (EOT) Visit (Day 11) in the ITT and Clinically Evaluable at EOT (CE-EOT) analysis sets [ Time Frame: Day 11 ] [ Designated as safety issue: No ]
  • To compare the Investigator's assessment of clinical success at the Post-Therapy Evaluation (PTE) Visit (7-14 days after the EOT Visit) in the ITT and Clinically Evaluable at PTE (CE-PTE) analysis sets [ Time Frame: 7-14 days after the EOT Visit ] [ Designated as safety issue: No ]
  • To compare the Investigator's assessment of clinical response at the 48-72 Hour and Day 7 Visits in the ITT analysis set [ Time Frame: 48-72 Hour and Day 7 Visits ] [ Designated as safety issue: No ]
  • To compare patient-reported pain, by study visit [ Time Frame: Multiple Visits ] [ Designated as safety issue: No ]
  • To evaluate the safety profile of TR-701 FA in comparison with that of linezolid [ Time Frame: Multiple Visits ] [ Designated as safety issue: Yes ]
  • To assess the population pharmacokinetic (PK) profile of TR-700 [ Time Frame: Multiple Visits ] [ Designated as safety issue: No ]

Detailed Description:
