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

• Status: Completed
• Trial end date: 2020-07-27
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Sichuan Haisco Pharmaceutical Group Co., Ltd; Sichuan Haisco Pharmaceutical Group Co., Ltd.
• Treatments: Propofol

2. Patient known to be allergic to eggs, soy products, opioids and their antidotes, and propofol; patient having contraindications to propofol, opioids and their antidotes;

3. Patients who have undergone endotracheal intubation and/or mechanical ventilation prior to diagnostic or therapeutic bronchoscopy;

4. Medical history or evidence of any of the following prior to screening/at baseline, which may increase sedation/anesthesia risk:

3. History of neurological and psychiatric disorders: craniocerebral injury, possible convulsions, intracranial hypertension, cerebral aneurysms, history of cerebrovascular accidents; schizophrenia, mania, insanity, long-term use of psychotropic drugs, and history of cognitive dysfunction;

4. History of gastrointestinal diseases: gastrointestinal retention, active hemorrhage, or history of gastroesophageal reflux or obstruction that may lead to aspiration;

5. History of uncontrolled clinically significant liver, kidney, blood system, nervous system or metabolic system diseases judged by the investigator to be probably unsuitable for involvement in the study;

6. History of alcohol abuse within 3 months prior to screening, abuse defined as average of > 2 units of alcohol per day (1 unit = 360 mL beer or 45 mL liquor with 40% alcohol or 150 mL wine);

7. History of drug abuse within 3 months prior to screening;

8. History of blood transfusion within 14 days prior to screening;

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:

1. Received any investigational drug within 1 month prior to screening;

2. Received propofol, other sedatives/anesthetics, and/or opioid analgesics or compounds containing analgesics within 72 h prior to baseline;

7. Laboratory results meeting any of the following criteria during screening/at baseline, confirmed by re-examination:
