Description of intervention(s) / exposure
HSK-3486
(single brief IV injection)
Planned dosing schedule change to:
Cohort 1 0.016 mg/kg
Cohort 2 0.064 mg/kg
Cohort 3 0.128 mg/kg
Cohort 4 0.192 mg/kg
Cohort 5 0.288 mg/kg
Cohort 6 0.432 mg/kg
Cohort 7 0.540 mg/kg
Cohort 8 0.648 mg/kg
Cohort 9 0.810 mg/kg

The maximum dose of HSK3486 will be the dose that either produces either

(i) Physiological changes (i.e. vital sign changes) beyond pre-defined ranges or

(ii) A PD effect of unconscious sedation/anesthesia for more than 15 minutes (as measured by a RASS score of - 5).

After the maximum dose has been reached by a subject in a cohort, the data will be reviewed by the DSMB. If the maximum dose is reached in Cohort 1 to 7 the DSMB can decide to either continue with the same dose, or complete cohort dosing at the dose level used in the preceding cohort. If the maximum dose is reached in Cohort 9 dosing of any further subjects will be ceased.

The aim is to have at least five subjects receive the pre-maximal dose, and five subjects receive propofol. Should maximal dosing be reached prior to Cohort 7, a subject will be actively allocated to the positive control.

In Cohorts 3 and 4 a sentinel subject will be enrolled to monitor any possible dose-related adverse effects at the higher doses. In Cohort 3, the dose will be increased by a factor of two. Thereafter, doses in subsequent cohorts will increase by a factor of 1.5, as they approach doses producing a RASS score of -5 for more than 15 minutes, unless the DSMB decides that a lower dose may be required based on findings from the previous cohorts.

The maximum dose of HSK3486 will be that which produces clinically significant hypotension, tachycardia or bradycardia (see below), or that produces a PD effect of anesthesia for more than 15 minutes as measured by RASS score of -5.

Acceptable range of vital signs during drug administration
Blood pressure, Systolic: 80-180 mmHg Blood pressure, Mean: 55-120 mmHg Heart rate: 40-120 bpm
Saturation: >95%

If the maximum dose is reached in Cohort 1 to 8 the DSMB can elect to either continue with the same dose, or complete cohort dosing at the dose level used in the preceding cohort. If the maximum dose is reached in Cohort 9 dosing of any further subjects will be ceased.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following Screening, subjects who meet the inclusion/exclusion criteria will be assigned a subject number in the order in which they are enrolled in the study. The subject number will determine the allocation of treatment as per the randomization list which will be generated by INCResearch Australia Pty Ltd and provided to the pharmacist. Cohorts 1 and 2 are a placebo controlled design, with open-labelling for the sentinel subjects and double-blind thereafter. Cohorts 3 to 8 are an open-label, positive controlled design.
Paper copies of the blinding envelopes will be produced and checked by internal quality control procedures. Copies will be given to the Pharmacist(s) for dispensing of study medication. One paper copy will be placed in a sealed envelope and retained in a secure restricted access area at the Study Site.
