Overview
Brief Summary
The purpose of this study is to evaluate safety, tolerability, pharmacokinetic characteristics and efficacy of TNP-2092 in adults with ABSSSI suspected or confirmed to be caused by gram-positive pathogens.
Detailed Description
This Phase 2, double-blind, randomized, multicenter, parallel, controlled study is conducted to evaluate safety, tolerability, pharmacokinetics and efficacy of TNP-2092, and vancomycin in adults with ABSSSI suspected or confirmed to be caused by gram-positive pathogens. The duration of the treatment period is a minimum of 7 days and a maximum of 14 days.

Outcomes
Primary Outcomes
Early Clinical Response at the Early Assessment Visit in the Modified Intent-to-Treat (mITT) Population
Time Frame: 48 to 72 hours after the first dose of study treatment
Early clinical response is defined as responder meeting two criteria: (1) patient had at least a 20% reduction of acute bacterial skin and skin structure infection (ABSSSI) primary lesion size compared to baseline measurements; (2) patient did not die of any cause within 72 hours of the first dose of study treatment. An indeterminate classification is used for a response that could not be adequately inferred because study data are unavailable for evaluation of efficacy for any reason (eg, missing data, lost to follow-up, did not attend the EA clinic appointment), or if the early assessment visit is out of the 48 to 72 hours window after the intravenous study treatment starts.
Early Clinical Response at the Early Assessment Visit in the Micro-Intent-to-Treat (Micro-ITT) Population
Time Frame: 48 to 72 hours after the first dose of study treatment
Early clinical response is defined as responder meeting two criteria: (1) patient had at least a 20% reduction of acute bacterial skin and skin structure infection (ABSSSI) primary lesion size compared to baseline measurements; (2) patient did not die of any cause within 72 hours of the first dose of study treatment. An indeterminate classification is used for a response that could not be adequately inferred because study data are unavailable for evaluation of efficacy for any reason (eg, missing data, lost to follow-up, did not attend the EA clinic appointment), or if the early assessment visit is out of the 48 to 72 hours window after the intravenous study treatment starts.
Early Clinical Response at the Early Assessment (EA) Visit in the Intent-to-Treat (ITT) Population
Time Frame: 48 to 72 hours after the first dose of study treatment
Early clinical response is defined as responder meeting two criteria: (1) patient had at least a 20% reduction of acute bacterial skin and skin structure infection (ABSSSI) primary lesion size compared to baseline measurements; (2) patient did not die of any cause within 72 hours of the first dose of study treatment. An indeterminate classification is used for a response that could not be adequately inferred because study data are unavailable for evaluation of efficacy for any reason (eg, missing data, lost to follow-up, did not attend the EA clinic appointment), or if the early assessment visit is out of the 48 to 72 hours window after the intravenous study treatment starts.
