Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of subjects with adverse events | Between screening and 7-9 days after dosing | To evaluate the safety and tolerability of HSK21542 in comparison with placebo after a single injection in healthy subjects in terms of adverse events |
| Number of subjects with abnormal physical examination/ abnormal vital signs/ abnormal laboratory parameters | Between screening and 7-9 days after dosing | To evaluate the safety and tolerability of HSK21542 in comparison with placebo after a single injection in healthy subjects in terms of abnormal physical examination/ abnormal vital signs/ abnormal laboratory parameters |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| t1/2 | From the start of administration to 24 hours after administration | Elimination half-life |
| AUC0-t | From the start of administration to 24 hours after administration | Area under the plasma concentration-time curve from time zero to time t. |
| Cmax | From the start of administration to 24 hours after administration | Maximum (peak) plasma drug concentration |
| CL | From the start of administration to 24 hours after administration | Apparent total body clearance of the drug from plasma |
| Vd | From the start of administration to 24 hours after administration | Apparent volume of distribution |
| AUC0-inf | From the start of administration to 24 hours after administration | Area under the plasma concentration-time curve from time zero to infinity |
