What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse events (AE)	Incidence of adverse events (AE)	Up to 18 days
Serious Adverse Events (SAE)	Incidence of serious adverse events (SAE)	Up to 18 days
Treatment-emergent adverse events (TEAEs)	Incidence of treatment-emergent adverse events (TEAEs)	Up to 18 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to peak concentration (Tmax)	The time it takes to reach the peak concentration	Up to 18 days
Peak concentration (Cmax)	Maximum plasma drug concentration	Up to 18 days
Area under the blood concentration-time curve	The amount of drug absorbed into the circulation after administration of a single dose can be estimated from the area under the blood concentration-time curve, with Auc in units of concentration * time.	Up to 18 days
Apparent volume of distribution (Vd/F)	It is the ratio of the amount of drug in the body to the blood concentration of the drug when the drug reaches dynamic equilibrium in the body is called the apparent volume of distribution.	Up to 18 days
Plasma clearance (CL/F)	It is the sum of drug clearance by the liver and kidneys, etc., i.e., how many volumes of plasma are cleared of drug per unit of time in L/h, or L/(kg-h) if calculated on the basis of body weight.	Up to 18 days
Plasma elimination half-life (t1/2)	The time required for the concentration of a drug in the blood or the amount of drug in the body to be reduced to 1/2. The time required for absorption, distribution and elimination of half the amount of drug (or blood concentration) in the body becomes the absorption half-life, distribution half-life and elimination half-life, respectively.	Up to 18 days
Steady-state peaking time (Tmax, ss)	The time required to reach a steady-state peak concentration after administration.	Up to 18 days
Steady state peak concentration (Cmax, ss)	The steady-state blood drug concentration is a serrated plasma drug concentration curve, with the highest steady-state blood drug concentration being the peak steady-state blood drug concentration.	Up to 18 days
Steady state valley concentration (Cmin, ss)	The steady-state blood drug concentration is a serrated plasma drug concentration curve, with the lowest steady-state blood drug concentration being the trough of the steady-state blood drug concentration.	Up to 18 days
Average steady-state blood drug concentration (Cav, ss)	The average concentration reached when the drug concentration reaches a steady state after a continuous given dose of medication.	Up to 18 days
Area under steady-state blood drug concentration time curve (AUC0- τ)	After a single dose administration, the amount of medication absorbed into the human bloodstream can be estimated using the area under the blood drug concentration time curve, with the unit of Auc being concentration * time.	Up to 18 days
Accumulation ratio (Rac)	The ratio of the required dose for a single administration to the total dose required for a split administration.	Up to 18 days
Renal clearance rate (CLr/F)	The ability of both kidneys to completely remove a substance equivalent to several milliliters of plasma within one minute.	Up to 18 days
INF-γ release	Inhibition efficiency of INF-γ release by TQH3906 in IL-12/IL-18-stimulated peripheral blood mononuclear cells from subjects.	Up to 18 days
QTcF interval	Effect of TQH3906 on the QTcF interval in healthy subjects.	Up to 18 days
