Phase I Clinical Study to Evaluate the Pharmacokinetics, Pharmacokinetics, and Safety of Intravenous Administration of Methoxyethyl Etomidate Hydrochloride for Injection in Subjects With Mild, Moderate, and Normal Hepatic Dysfunction.

ET-26-HCl-CP-003

A Phase I clinical study to compare the pharmacokinetics, pharmacokinetics, and safety of intravenous administration of methoxyetomidate hydrochloride for injection in subjects with mild hepatic insufficiency (Child-pugh A), moderate hepatic insufficiency (Child-Pugh B), and normal hepatic function.Main OBJECTIVE: To evaluate the pharmacokinetic characteristics of metoetomidate hydrochloride for injection in subjects with mild liver dysfunction (Child-Pugh A), moderate liver dysfunction (Child-Pugh B) and normal liver function, and to provide evidence for the clinical application of metoetomidate hydrochloride in patients with liver dysfunction.Secondary objective: To evaluate the safety and pharmacokinetics of metoetomidate hydrochloride for injection in subjects with mild hepatic insufficiency (Child-Pugh A), moderate hepatic insufficiency (Child-Pugh B), and normal hepatic dysfunction.Exploratory objective: To investigate and analyze the relationship between the pharmacokinetic index (MOAA/S, BIS) and the pharmacokinetic parameters of metoetomidate hydrochloride in subjects with different liver function states in this study.The CYP2C19 genotype of the subjects in the study was analyzed, and the influence of gene polymorphism on pharmacokinetic parameters of metoetomidate hydrochloride was explored according to the data of CYP2C19 genotype.The relationship between in vivo exposure to methoxyetomidate hydrochloride and liver injury was analyzed.

Participants who participated in any drug clinical trials within 2 months prior to screening (Participants with liver dysfunction who participated in three or more drug clinical trials within 1 year prior to screening should also be excluded) 10. ECG abnormalities were clinically significant and were judged by the investigator to be unsuitable for participation in the study \[if tachycardia/bradycardia, degree II-III atrioventricular block, or prolonged QTcF interval requiring drug therapy (male ≥470 ms, female ≥480 ms),Corrected by Fridericia's formula) or otherwise clinically significant abnormalities determined by the clinician\] 11. Female subjects were lactating or had a positive blood pregnancy during the screening period or during the trial 12. Subjects with normal liver function who tested positive for any of the indicators of hepatitis B surface antigen, hepatitis C antibody or hepatitis C core antigen, HIV antigen/antibody or syphilis antibody 13. Patients with serious or clinically significant infections (such as respiratory or central nervous system infections), trauma, or major surgical operations within 4 weeks prior to screening 14.
