A Study Evaluating Safety, Pharmacodynamics and Pharmacokinetics of HSK3486 and Etomidate for Induction of Anesthesia in Healthy Male Subjects
- Registration Number
- NCT04054063
- Lead Sponsor
- Sichuan Haisco Pharmaceutical Group Co., Ltd
- Brief Summary
This study is designed as an open label, single dose combination of HSK3486 and etomidate in healthy adult male subjects. The study will evaluate the anesthetic/sedation effect of the combination of the 2 drugs and the safety profile including pain on injection, hypotension, tachycardia or bradycardia effects (HSK3486), and involuntary muscle movements, nausea and vomiting potential and adrenal suppression (etomidate).
All subjects will be administered HSK3486 plus etomidate. Subjects will be confined to the study unit from the evening of Day -1 until the morning of Day 2, then will be required to return for a follow up visit on Day 7.
Intensive PD, PK, safety and tolerability and assessments will be performed prior to dosing on Day 1 until 24 hours post-dose (Day 2).

Group Intervention Description HSK3486+etomidate HSK3486+ etomidate Cohort 1: HSK3486 0.324 mg/kg + etomidate 0.15 mg/kg Cohort 2: HSK3486 0.216 mg/kg + etomidate 0.2 mg/kg Cohort 3: HSK3486 0.432 mg/kg + etomidate 0.1 mg/kg There were an additional 2 cohorts (Cohorts 4 and 5) planned for dose escalation once the optimal ratio of the drug combination was identified from the first 3 cohorts. However, these 2 cohorts were not done as the results of Cohorts 1 to 3 suggested that dose increases would cause higher occurrence of drug-related adverse events (AEs).
