A Study of the Relative Bioavailability of ASC41 in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to compare the pharmacokinetic parameters of ASC41 in healthy subjects after single and multiple oral dosing.

Detailed Description
-----------------
The purpose of this study was to evaluate the tolerability, safety pharmacokinetics and pharmacodynamic (biomarkers) of ASC41 tables in a randomized, double-blind, placebo-controlled single- and multiple-dose phase I clinical trial in healthy subjects the study. The effects of ASC41 on LDL-C and other lipid parameters (TG, TC, HDL-C, etc.) will be observed after repeated administration of ASC41 in healthy subjects.

Those who voluntarily sign the informed consent. Exclusion Criteria: 1. Patients with a history of thyroid disease or intolerance to beta blockers or abnormal thyroid function indicators during screening; 2. Previous history of fainting, fainting needle or fainting blood for unknown reasons. 3. Previous liver disease, or ALT, ASL and direct bilirubin in screening period exceed the normal range. 4. Hepatitis B surface antigen (HBsAg), Hepatitis C virus antibody (HCV Ab), HIV antibody (HIV Ab) and syphilis antibody are tested positive. 5. People who have taken special diet (including carambola, dragon fruit, mango, grapefruit, orange, etc.) or drunk alcohol, or had strenuous exercise, or other factors affecting drug absorption, distribution, metabolism, and excretion within 2 weeks before taking the study drug. 6. Heavy smokers (14 units of alcohol per week: 1 unit = 285 mL beer, or 25 mL spirits, or 100 mL wine;Smoking daily ≥ 5 sticks) and no smoking or alcohol prohibition during the study period. 7. Ingesting chocolate, any food or drink containing caffeine or xanthine in the 24 hours prior to taking the study drug. 8. Patients who had donated blood or lost blood of more than 400ml within 3 months before taking the study drug. 9. Those who have participated in other clinical trials and received study drug treatment within 3 months before taking study drug. 10. In addition to the above, the researchers judge that the participants are not suitable to participate in this clinical trial.
