TR-701 FA vs Linezolid for the Treatment of Acute Bacterial Skin and Skin Structure Infections

Phase 3
Completed
Conditions
Skin and Subcutaneous Tissue Bacterial Infections
Interventions
Registration Number
NCT01421511
Lead Sponsor
Trius Therapeutics LLC, a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA)
Brief Summary

This is a randomized, double-blind, double-dummy, multicenter, global Phase 3 study of IV to oral TR-701 FA 200 mg once daily for 6 days versus IV to oral Zyvox® (linezolid) 600 mg every 12 hours for 10 days for the treatment of ABSSSI in adults. Patients are to start treatment with at least 2 IV doses and may receive IV therapy for the entire treatment duration.

Approximately 100 to 140 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.

Detailed Description

The primary objective is to determine the noninferiority (NI) in the early clinical response rate of intravenous (IV) to oral 6 day TR-701 free acid (FA) compared with that of IV to oral 10-day linezolid treatment at 48-72 hours after the first infusion of study drug in the intent-to-treat (ITT) analysis set in patients with acute bacterial skin and skin structure infections (ABSSSI).

Primary Outcome Measures
NameTimeMethod
The Early Clinical Response Rate48-72 hours

Responder: No increase in lesion surface area from baseline.

Secondary Outcome Measures
NameTimeMethod
Investigator's Assessment of Clinical Success of the Post Therapy Evaluation Visit in Clinically Evaluable-Post Treatment Evaluation Analysis Set.Post-Treatment Evaluation (7-14 days after the End of Therapy)

Clinical success defined as resolution/near resolution of disease specific signs and symptoms, absence/near resolution of baseline systemic signs of infection, no new signs, symptoms or complications attributable to the ABSSSI and no further antibiotic therapy required for treatment of primary ABSSSI lesion.

Clinical Response at the End of Therapy Visit in the Clinically Evaluable at End of Therapy Analysis SetEnd of Therapy Day 11

Responder: No increase in lesion surface area from baseline.

Investigator's Assessment of Clinical Success at the Post Treatment Evaluation VisitPost-Treatment Evaluation (7-14 days after the End of Therapy)

Clinical success defined as resolution/near resolution of disease specific signs and symptoms, absence/near resolution of baseline systemic signs of infection, and no further antibiotic therapy required for treatment of primary ABSSSI lesion.

Change From Baseline in Patient-reported Pain, by Study VisitMultiple

0=no pain, 10=worst pain Only 1 visit per participant for Day 4-6, only 1 visit for Day 7-9, and only 1 visit for Day 10-13.

Investigator's Assessment of Clinical Response at the 48-72 Hour Visit48-72 Hours

Clinical improvement defined as improvement in overall clinical status.

Investigator's Assessment of Clinical Response at the Day-7 VisitDay 7

Clinical improvement defined as improvement in overall clinical status.

Clinical Response at the End of Therapy VisitDay 11

Responder: No increase in lesion surface area from baseline.
