A Clinical Trial Evaluating the Efficacy and Safety of HSK3486 Injectable Emulsion in Elective Surgery Patients
Study Details
Study Description
Brief Summary
This is a multi-center, randomized, open-label, positive-controlled (propofol) phase II clinical trial. The study plans to enroll approximately 46 eligible subjects. Among them, 40 subjects will be randomly assigned to HSK3486 treatment group (30 cases) and propofol control group (10 cases) in a ratio of 3:1. The subjects will be enrolled competitively at all study sites. Upon enrollment of the 40 subjects, 6 more subjects will be enrolled by West China Hospital of Sichuan University. These 6 subjects will not be randomized, but will directly enter into propofol induction + HSK3486 maintenance group for study.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: HSK3486 HSK3486 induction + maintenance group |
Drug: HSK3486
The induction dose is 0.4mg/mg. The initial maintenance dose of the first 6 subjects is 1 mg/kg/h. For the subsequent enrolled subjects, the investigator could adjust the subsequent initial maintenance dose according to the dose response of the first 6 subjects, so as to explore the optimal initial maintenance dose. The range of the initial maintenance dose is 1 (± 0.5) mg/kg/h, i.e. the minimum initial maintenance dose should not be less than 0.5 mg/kg/h, and the maximum should not be more than 1.5 mg/kg/h.
|
| Active Comparator: Propofol Propofol induction + maintenance group |
Drug: Propofol
The induction dose is 2.0mg/mg. The initial maintenance dose of the first 2 subject is 5 mg/kg/h. For the subsequent enrolled subjects, the investigator could adjust the subsequent initial maintenance dose according to the dose response of the first 2 subjects, so as to explore the optimal initial maintenance dose. The adjustment range of the initial maintenance dose is 5 (± 2.5) mg/kg/h, i.e. the minimum initial maintenance dose should not be less than 2.5 mg/kg/h, and the maximum should not be more than 7.5 mg/kg/h.
|
| Other: Propofol HSK3486 Propofol induction + HSK3486 maintenance group |
Drug: Propofol HSK3486
The induction dose of Propofol is 2.0mg/mgThe initial maintenance dose of HSK3486 is fixed at 1 mg/kg/h, without adjustment.

Outcome Measures
Primary Outcome Measures
- Success rate of anesthesia maintenance [During maintenance of general anesthesia on day 1]
During the maintenance of anesthesia, the subject is not recovered and no remedial anesthetic is used
- Number of patients with adverse events [Pre-dose to 48 hours post-dose]
Safety endpoints
Secondary Outcome Measures
- Success rate of anesthesia induction [During induction of general anesthesia on day 1]
During the induction of anesthesia, the subject achieves successful induction (i.e., MOAA/S ≤ 1) after administration of the study drug (up to 2 additional doses), and no remedial anesthetic is used.
- Success rate of anesthesia [During induction and maintenance of general anesthesia on day 1]
The proportion of subjects who are successfully induced and successfully maintain anesthesia in all subjects.
- Changes in Bispectral index [During maintenance of general anesthesia on day 1]
Bispectral index (BIS) is used to adjust the administration dose during anesthesia maintenance to maintain BIS at 40-60
- Time to successful induction of anesthesia [Time to successful induction of anesthesia on day 1]
A period of time from the start of the first administration of the study drug to the first time when MOAA/S is ≤ 1.
- Time to recovery from anesthesia [A period of time from discontinuation of the study drug to recovery after the end of surgery on day 1.]
6.Record the time when MOAA/S = 5 is reached for the first time.
- Time to respiratory recovery [A period of time from discontinuation of the study drug to respiratory recovery after the end of surgery on day 1.]
Respiratory rate ≥ 8 breaths/min and the tidal volume ≥ 5 mL/kg.
- Time to extubation [A period of time from discontinuation of the study drug to extubation after the end of surgery on day 1.]
- Time to leaving the operating room [A period of time from discontinuation of the study drug to leaving the operating room after the end of surgery on day 1.]
- Time to leaving postanesthesia care unit(PACU) [A period of time from discontinuation of the study drug to leaving PACU after the end of surgery on day 1.]
