- Primary Outcome Measures
Name Time Method Incidence of Adverse Events(AEs) up to 17 days The percentage of subjects with at least one AEs.
- Secondary Outcome Measures
Name Time Method Area Under the Plasma Concentration-Time Curve from the First Dose to the Last Measurable Concentration (AUC 0-last) Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15 Plasma concentrations of TNP-2198 were measured by a specific and validated assay. Plasma PK parameters of TNP-2198 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods.
Area Under the Plasma Concentration-Time Curve from the First Dose Extrapolated to Infinity (AUC0-∞) Day 1,Day 3, Day 5, Day 7, Day 9, Day 11, Day 13, Day 14, Day 15 Plasma concentrations of TNP-2198 were measured by a specific and validated assay. Plasma Pharmacokinetics (PK) parameters of TNP-2198 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods.
