Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All subjects will receive a combined dose of HSK3486 and etomidate administered as a single bolus IV injection (a prepared pre-mixed formulation containing HSK3486 and etomidate micro-emulsion formulations) via infusion pump over 60 seconds into the antecubital fossa of the hand.
There are a total of 5 cohorts, of 5 subjects planned for the study. The doses for Cohorts 1 to 3 have been selected based on reductions to the individual recommended clinical doses for each of HSK3486 and etomidate to make a total anesthetic dose similar to a standard dose of propofol of 2.5 mg/kg.
The doses for Cohorts 4 and 5 will be determined following an interim review by the SRC of the safety and PD results for the completed Cohorts 1 to 3 (up to Day 7).
The proposed doses for each of the cohorts are as follows:
Cohort 1: 0.324 mg/kg HSK3486 plus 0.15 mg/kg etomidate
Cohort 2: 0.216 mg/kg HSK3486 plus 0.2 mg/kg etomidate
Cohort 3: 0.432 mg/kg HSK3486 plus 0.1 mg/kg etomidate
Cohort 4: Dose for HSK3486 and etomidate to be confirmed
Cohort 5: Dose for HSK3486 and etomidate to be confirmed
Dosing of subjects will occur at intervals of no less than 2 hours, to assess short-term safety between subjects.
On the evening of check-in subjects may be given dinner or snacks but must fast from 11:00 pm through at least 6 hours from the start of investigational product administration. During this time water is permitted but must be ceased at least 2 hours prior to the schedule dose time.

Outcomes
Primary outcome [1] 299834 0
Assess the safety & tolerability of a single bolus intravenous (IV) injection of combinations of HSK3486 and etomidate for induction of anesthesia in healthy adult male subjects.
Timepoint [1] 299834 0
A complete physical examination will be conducted at the Screening. At Day 1 a brief exam will be performed to confirm no changes from screening.
Vital signs (respiratory rate, heart rate, pulse oximetry, temperature, non-invasive BP [systolic and diastolic BP and MAP]) will be measured at the Screening visit, Day -1, and during the Treatment Visit( every 1 min during 0 min to 30 min, every 5 min during 30 min to 60 min, 2 hours (+/- 10 minute), 4 hours (+/- 10 minutes), 8 hours (+/- 10 minutes) , 12 hours (+/- 10 minutes) and 24 hours post dose (+/- 30 minutes) ) and at the Follow up visit.
The laboratory tests are to be performed at Screening, Day -1, 24 hours post-dose at the Treatment Visit and the Follow-Up Visit.
Computerized 12-lead ECG will be performed at the Screening visit. At the treatment visit, a continuous 3-lead ECG will be performed for 30 minutes (+/- 1 minute) prior to dosing and for the first 2 hours (+/- 1 minute) post dosing. Also a 12-lead ECG will be performed at 30 minutes (+/- 1 minute) prior to dosing, then at 0, 10, 15, 30 minutes (+/- 1 minute) and 1 hour (+/- 1 minute) post dose.
The presence of involuntary movements will be recorded from the onset of drug administration until RASS has returned to baseline.
Neurovascular assessments of the hand distal to the placement of the arterial line are to be performed every 30 minutes (+/- 1 minute) from the time of arterial line insertion until removal. Following removal of the line, the assessments will be performed every 4 hours (+/- 10 minutes) for 8 hours and at 24 hours post dose.
Primary outcome [2] 300259 0
Assess the pharmacodynamics (PD) of a single bolus intravenous (IV) injection of combinations of HSK3486 and etomidate for induction of anesthesia in healthy adult male subjects.
Timepoint [2] 300259 0
Onset of sedation/anesthesia will be defined as the time to loss of response to oral command and time to loss of eyelash reflex. Loss of response to oral command is captured under RASS, and eyelash reflex will be sought every 15 seconds after dosing until absent.
The RASS will be measured during the Treatment Visit evaluated and recorded at every minute post dose until the RASS score recovers to 0 for consecutive 3 minutes.
The EEG (raw EEG) and the processed parameter BIS will be recorded during the Treatment Visit with BIS values evaluated and recorded at every minute post dose until the RASS score recovers to 0 for consecutive 3 minutes using a fronto-parietal montage.
A subject assessment of the quality of recovery after anesthesia will be conducted using the QoR-9 which is to be performed prior to dosing, 10 minutes after a RASS score of 0, and 24 hours post-dose during the Treatment Visit.
Secondary outcome [1] 328250 0
Assess the pharmacokinetics (PK) of IV injected HSK3486, in the presence of etomidate, in healthy subjects.
The plasma concentration of HSK3486 will be analyzed using non-compartmental analytical procedures and validated software to estimate the following PK parameters:
Maximum observed plasma concentration (Cmax)
Time to maximum plasma concentration (tmax)
Area under the plasma concentration-time curve from time zero to the time of the last measurable concentration and time zero to infinity (AUC0-last and AUC0-inf)
Apparent terminal elimination rate constant (kel)
Apparent terminal elimination half-life (t1/2)
Clearance (CL)
Volume of distribution (Vd)
Mean residence time from time zero to infinity (MRT0-inf)
Timepoint [1] 328250 0
Samples for PK are to be collected as follows: within 30 minutes prior to dosing; 0.5 minutes, 1 minute, 1.5 minutes, 2 minutes, 4 minutes, 5 minutes, 8 minutes, 12 minutes, 15 minutes, 30 minutes, 1 hour (+/- 1 minute), 1.5 hours (+/- 1 minute), 2 hours (+/- 2 minute), 4 hours (+/- 2 minutes), 8 hours (+/- 2 minutes) and 24 hours post dose (+/- 2 minutes).

Summary
Brief summary
This study is designed as an open label, single dose combination of HSK3486 and etomidate in healthy adult male subjects. The study will evaluate the anesthetic/sedation effect of the combination of the 2 drugs and the safety profile including pain on injection, hypotension, tachycardia or bradycardia effects (HSK3486), and involuntary muscle movements, nausea and vomiting potential and adrenal suppression (etomidate).
All subjects will be administered HSK3486 plus etomidate. Subjects will be confined to the study unit from the evening of Day -1 until the morning of Day 2, then will be required to return for a follow up visit on Day 7.
Intensive PD, PK, safety and tolerability and assessments will be performed prior to dosing on Day 1 until 24 hours post-dose (Day 2).
