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

Phase 3

Completed

• Conditions: Sedation or Anesthesia
• Interventions: Drug: HSK3486; Drug: Propofol

• Registration Number: NCT04111159
• Lead Sponsor: Sichuan Haisco Pharmaceutical Group Co., Ltd

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Success rate of fiberoptic bronchoscopy. A successful diagnosis/treatment should meet both of the following:	During induction of sedation/anesthetic on day 1	1. Completion of fiberoptic bronchoscopy; 2. 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.

Secondary Outcome Measures

Name	Time	Method
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	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	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
Time to discharge	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	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
Use of questionnaires to estimate sedation/anesthesia satisfaction, including satisfaction assessments of the subject and anesthesiologist	During induction of sedation/anesthetic on day 1
Use of the investigational drug and alternative drugs	During induction of sedation/anesthetic on day 1
