Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety and tolerability of SYHX1901 tablets | SAD: up to14 days after the dosing, MAD: up to 7 days after the last dosing | The safety and tolerability of single or multiple doses of SYHX1901 tablets administered orally will be assessed by incidence and severity of adverse events (AEs), abnormalities in clinical laboratory assessments, ECGs, vital sign assessments, and physical exams. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Urine PK parameters | Pre-dose and multiple timepoints up to 144 hours after the dose（180 mg） | Urine pharmacokinetic parameters: The Urine clearance rate （CLr）of SYHX1901 |
| Fecal PK parameters | Pre-dose and multiple timepoints up to 144 hours after the dose（180 mg） | Fecal pharmacokinetic parameters: cumulative excretion from time t1 to t2(Aft1-t2) |
| The PK of SYHX1901 following single-dose and multiple doses | Pre-dose and multiple timepoints up to 144 hours after the last dose | Peak Plasma Concentration (Cmax) of SYHX1901 following single-dose and multiple doses |
| PD indexes: the level of PSTATs in blood cells | Pre-dose and multiple timepoints up to 144 hours after the last dose | Pharmacodynamic indexes: the level of PSTATs in blood cells |
| PD indexes: the inhibition rate of PSTATs in blood cells | Pre-dose and multiple timepoints up to 144 hours after the last dose | Pharmacodynamic indexes: the inhibition rate of PSTATs in blood cells |
| Identification of Metabolites of SYHX1901 | Pre-dose and multiple timepoints up to 144 hours after the dose（180 mg） | It is a prospective study aiming to characterize metabolites of 1901 in human plasma, urine and feces. The metabolism profiles of 1901 and main metabolites will be build up. |
