What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Adverse Events (AEs) | An Adverse Event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An Adverse Event can therefore be any unfavorable and unintended sign (including abnormal laboratory values or abnormal clinical test results), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as Adverse Events. | Day 1 to Day 4 | 
| Area Under the Plasma Concentration Versus Time Curve Extrapolated to Infinity (AUC0-inf) | Plasma concentrations of TNP-2092 were measured by a specific and validated assay. Plasma Pharmacokinetics (PK) parameters of TNP-2092 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods | Before the first (Day1) administration (within 15 minutes), and 0.5 hour (h), 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, 10 h, 12 h, 16 h, 24 h, 36 h, 48 h and 72 hours (h) after administration | 
| Area Under the Plasma Concentration Versus Time Curve from 0 to the Last Measurable Concentration (AUC0-t) | Plasma concentrations of TNP-2092 were measured by a specific and validated assay. Plasma PK parameters of TNP-2092 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods. | Before the first (Day1) administration (within 15 minutes), and 0.5 hour (h), 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, 10 h, 12 h, 16 h, 24 h, 36 h, 48 h and 72 hours (h) after administration | 
| Maximum Observed Plasma Concentration (Cmax) of TNP-2092 | Plasma concentrations of TNP-2092 were measured by a specific and validated assay at specified time points | Before the first (Day1) administration (within 15 minutes), and 0.5 hour (h), 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, 10 h, 12 h, 16 h, 24 h, 36 h, 48 h and 72 hours (h) after administration |
