A Study in Subjects With Liver Function Injury and Subjects With Normal Liver Function

Study Overview
=================
Brief Summary
-----------------
Evaluate the pharmacokinetic differences of the main metabolite 116-N1 of JT001 in subjects with mild and moderate liver function impairment and those with normal liver function, providing a basis for formulating clinical medication plans for patients with liver function impairment;

Detailed Description
-----------------
This study adopts a non randomized, open, parallel controlled, single dose experimental design and is divided into three experimental groups: mild liver function impairment group (Group A), moderate liver function impairment group (Group B), and normal liver function subject group (Group C). Subjects in each experimental group took 0.3g of JT001 orally on an empty stomach and collected blood samples before and after administration for pharmacokinetic analysis. After both groups A and B were enrolled, Group C subjects will be enrolled subsequently and should be matched with subjects with liver function impairment (Group A and Group B) as following: The average body weight of Group C is within ± 10 kg of the average body weight of the group of subjects with liver function impairment (Groups A and B). The average age of Group C is within ± 10 years of the average age of the group of subjects with liver function impairment (Groups A and B). The number of subjects of each gender in Group C is similar to that in the liver function impairment group (A and B groups) (± 1 subject/gender). The study is divided into three stages: screening period, baseline period, and experimental period.

Screening for alcoholics within the first three months, i.e. those who consume more than 14 units of alcohol per week (1 unit=360 mL of beer, or 45 mL of 40% alcohol or 150 mL of wine) or those who are positive for alcohol screening; Individuals who smoke an average of 10 or more cigarettes per day within the first 3 months of screening; Subjects with normal liver function who meet any of the following exclusion criteria need to be excluded: History of liver injury; Individuals who have previously or currently suffered from any clinical serious diseases such as circulatory system, endocrine system, nervous system, digestive system, respiratory system, hematology, immunology, psychiatry, and metabolic abnormalities, or any other diseases that may interfere with the test results; Abnormalities in physical examination, vital signs, laboratory examination, 12 lead electrocardiogram, abdominal ultrasound, and other examinations have been determined by the researcher to have clinical significance; Those who are positive in any index screening of hepatitis B surface antigen, hepatitis C antibody or hepatitis C core antigen, HIV antigen/antibody or syphilis antibody; Have used any prescription drugs, over-the-counter drugs, Chinese herbal medicines, or supplements within 14 days prior to the administration of the study drug; Subjects with liver function impairment who meet any of the following exclusion criteria need to be excluded: The subject has any of the following conditions: drug-induced liver injury; History of liver transplantation; And researchers believe that liver cirrhosis During screening, the laboratory test results meet any of the following criteria: (a) alanine aminotransferase (ALT) or aspartate aminotransferase (AST)>5 × ULN; (b) Absolute value of neutrophils (NE #)<1 × 109/L; (c) Hemoglobin (HGB)<80 g/L; (d) Alpha fetoprotein (AFP)>100 ng/mL; Except for the primary liver disease itself, those who have previously or currently suffered from other serious organ system diseases, including but not limited to gastrointestinal, respiratory, renal, neurological, hematological, endocrine, tumor, immune, mental, or cardiovascular diseases or clinical laboratory examination abnormalities, which have clinical significance, and are determined by the research doctor to be unsuitable for participating in this trial;
