This is a double-blinded, placebo controlled, single ascending dose (SAD), multi-cohort trial.
concentrations, HSK21542 concentration, pharmacokinetics parameters and identification of HSK21542 metabolites in urine. Also faeces samples will be collected, and faecal weight recorded pre-dose and at specified time intervals up to 48 h post dose for determination of HSK21542 concentration and identification of HSK21542 metabolites in feces.

The study will consist of a total of 72 participants are planned to be enrolled and allocated into 9 dose cohorts at the following dose levels: 0.2, 0.5, 1, 1.5 , 0.02, 0.05 and 1 µg/kg by intravenous injection at 40 mL/h over a period of 15 minutes using an intravenous pump.

Each dose cohort will include 8 participants (active:placebo = 6:2). Each participant can only be involved in one dose cohort. Participants receiving HSK21542 will be given a single dose of HSK21542 via intravenous injection on Day 1, and participants receiving placebo will be given a single dose of matched placebo via intravenous injection on Day 1 with same administration as active drug. Participants will be confined at the clinical facility from Day -1 through to Day 3, when they will be discharged following completion of all assessments. Participants will return to the clinical facility for final safety assessments at an End of Study (EOS) visit on Day 8 ± 1 day.


Dosing in each dose cohort will start with two sentinel participants with one of the two sentinels randomized to receive HSK21542 and the other randomized to receive placebo. The safety and tolerability of each sentinel will be monitored until Day 3 and will be reviewed prior to dosing the remainder of participants in each cohort. The study principal investigator (PI) will review safety/tolerability information available on the sentinel participants on Day 3 and will make the decision to dose the remaining 6 participants in the cohort.

Cohorts will be dosed in an escalating order, each dose level increased by no more than 2.5-fold over the previous dose level. The dose of a cohort may be appropriately adjusted according to the results of the previous dose cohort. The decision to escalate between dose levels will be based upon review of blinded safety data (ie, haematology, biochemistry, coagulation, thyroid function, blood electrolytes, ECG, vital signs and AE data) through to Day 8 and available blinded PK data by the Safety Monitoring Group (SMG).
The SMG will consist of the PI, an independent Medical Monitor and a sponsor medical representative. The SMG will review the data, discuss the findings, and decide to:
a) enrol the next dose group at the protocol-defined higher dose level;
b) enrol the next dose group at an intermediate higher dose level;
c) enrol the next dose group at a lower dose level than the current dose level; or
d) terminate enrollment in the study.
If the dose level is determined not to be safe and tolerated, the study drug assignment for those participants with a safety concern may be unblinded.

Dosing will proceed to the next dose level until evaluation of the maximum dose specified in the protocol (20 µg/kg) or the trial is stopped by the SMG. The trial can be terminated at any stage during escalation when any of the criteria for termination are met, even if the maximum dose is not reached.

For Cohort 4 (1,5µg/kg dose) only:
Urine samples will be collected pre-dose and at specified time intervals up to 48 h post dose for determination of electrolyte (sodium, potassium, calcium, magnesium, and chlorine) concentrations, HSK21542 concentration, pharmacokinetics parameters and identification of HSK21542 metabolites in urine. Also faeces samples will be collected, and faecal weight recorded pre-dose and at specified time intervals up to 48 h post dose for determination of HSK21542 concentration and identification of HSK21542 metabolites in feces.

Summary
Brief summary
The research project is testing a potential new treatment for acute and chronic pain called HSK21542. Before a new medicine can be approved for use for humans, it is necessary to confirm that it is safe and effective. This is done by carrying out clinical research studies such as this one.

The purpose of this study is to evaluate the safety and tolerability of a single dose of HSK21542. The pharmacokinetics (PK) of HSK21542 in humans will also be determined. PK testing involves taking blood, urine and faeces to measure how much of the drug get into the bloodstream and how long the body takes to get rid of it. When testing for PK the sample will also be tested for metabolites (breakdown products)of HSK21542.
