200 mg single dose group (low-dose group)	Experimental	Participants in the single-dose groups (200 mg in the low-dose group) were enrolled and received a single intravenous infusion of TNP-2092 for injection(Day 1) over 60 min (± 1 0 min).	Drug: TNP-2092 for injection Drug: placebo
300 mg single and multiple dose continuous dose group (medium-dose group)	Experimental	Participants in the single-dose, multiple-dose continuous dosing group (300 mg in the medium-dose group) received a single intravenous infusion of TNP-2092 for injection on Day 1 of the study. Subsequently, TNP-2092 for injection or placebo was administered as an intravenous infusion every 12 hours (q12 h, ± 10 min) daily on Study Days 4 to 10, and the last dose of TNP-2092 for injection was administered on the morning of Study Day 11.	Drug: TNP-2092 for injection Drug: placebo
400 mg single dose group (high-dose group)	Experimental	Participants in the single-dose groups (400 mg in the high-dose group) were enrolled and received a single intravenous infusion of TNP-2092 for injection over 60 min (± 1 0 min)	Drug: TNP-2092 for injection Drug: placebo

Outcomes Module

Primary Outcomes

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 14
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 pharmacokinetic(PK) parameters of TNP-2092 were read directly from the plasma concentration versus time profiles or calculated by using standard non-compartmental methods.	10, 20, 30, 45 minutes, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72 hours after the end of infusion
Area Under the Plasma Concentration Versus Time Curve from 0 to the Last Measurable Concentration (AUC0-last)	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.	10, 20, 30, 45 minutes, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72 hours after the end of infusion
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	10, 20, 30, 45 minutes, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 6, 8, 10, 12, 18, 24, 36, 48, 72 hours after the end of infusion

Physical examinations, vital signs, and clinical laboratory tests are normal, or non-clinically significant abnormal judged by Investigator.
Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

Exclusion Criteria:

History or clinical manifestations of significant central nervous system, cardiovascular, pulmonary, hepatic, renal, metabolic, other gastrointestinal, urological, endocrine or hematological disease that, in the opinion of the investigator, would confound the study results or compromise subject safety.
History or presence of alcohol or drug abuse, or illegal drug use.
Loss or donation of blood (> 450 mL) within 3 months prior to the start of the Screening Period.
Any history of allergic drug reactions, or any contraindication to the use of rifampin/rifamycin or a fluoroquinolone.
Taking any medication known to induce or inhibit CYP enzymes within 28 days prior to screening.
Taking any prescribed or over-the-counter medications within 2 weeks prior to screening, or during the trial, including vitamins, food supplements, herbal remedies, or traditional Chinese remedies.
Significant abnormal findings on clinical laboratory tests, in the opinion of the Investigator, could jeopardize achieving the study objectives and/or compromise the participant's safety, including but not limited to:
1. Hematology: hemoglobin (HGB), white blood cell (WBC), absolute neutrophil count (ANC), or platelet count (PLT) < the lower limit of normal (LLN).
2. Liver function: aspartate aminotransferase (AST) > the upper limit of normal (ULN), and/or alanine aminotransferase (ALT) > ULN, and/or total bilirubin > ULN.
3. Renal function: serum creatinine > ULN.
Tests positive for the human immunodeficiency virus (HIV) antibody, treponema pallidum antibody, hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV) antibody, and/or urine drug screening.
Abnormal findings on vital signs, in the opinion of the Investigator, could jeopardize achieving the study objectives and/or compromise the participant's safety, including but not limited to:
