A Trial Evaluating the Efficacy and Safety of HSK3486 Injectable Emulsion in Subjects Undergoing Fiberoptic Bronchoscopy

A Multi-Center, Randomized, Double-Blind, Propofol-Controlled Phase III Clinical Trial Evaluating the Efficacy and Safety of HSK3486 Injectable Emulsion for the Induction of Sedation/Anesthesia in Subjects Undergoing Fiberoptic Bronchoscopy

This is a Multi-Center, Randomized, Double-Blind, Propofol-Controlled Phase III Clinical Trial. Around 260 eligible subjects are planned to be enrolled and randomized in a 1:1 ratio to either the HSK3486 arm or propofol arm. The main objective is to evaluate the efficacy of HSK3486 vs. propofol for the induction of sedation/anesthesia in subjects undergoing fiberoptic bronchoscopy.

   2. Sleep apnea syndrome;
   3. History of malignant hyperthermia or family history;
   4. History of failed tracheal intubation;
   5. Difficult airway (modified Mallampati score ≥ III) as determined by the investigator;

6. Patient who received any of the following medications or treatments during screening/at baseline:

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Success rate of fiberoptic bronchoscopy. A successful diagnosis/treatment should meet both of the following:	Completion of fiberoptic bronchoscopy;; No alternative sedation/anesthetic drugs are used, that is, the number of doses of the study drug is ≤ 5 times within any given 15-minute period, starting from the initial administration until the fiberoptic bronchoscopy is completed.	During induction of sedation/anesthetic on day 1

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to successful sedation/anesthetic induction		From the initial administration of the investigational drug to the first time when MOAA/S is ≤1 on day 1
Time to fully awake	the time from the withdrawal of the bronchoscope or the last dose of the study drug to the first of 3 consecutive MOAA/S scores = 5	From the last dose of study drug or rescue sedative AND from end of fiberoptic bronchoscopy until the patient has recovered to fully alert on day 1
Time to discharge	the time from the withdrawal of the bronchoscope or the last dose of the study drug to the first of 3 consecutive Aldrete scores ≥ 9	Time from the last dose of study drug or rescue sedative and from the end of fiberoptic bronchoscopy until discharge (defined as the ability to walk unassisted) on day 1
Use of the investigational drug and alternative drugs		During induction of sedation/anesthetic on day 1
Use of questionnaires to estimate sedation/anesthesia satisfaction, including satisfaction assessments of the subject and anesthesiologist		During induction of sedation/anesthetic on day 1
