Pharmacokinetic Study of HS-10241 Tablets in Subjects with Hepatic Impairment and Normal Hepatic Function

Pharmacokinetic Study of HS-10241 Tablets in Subjects with Hepatic Impairment and Normal Hepatic Function

This study will be conducted in subjects with moderate Hepatic Impairment, mild hepatic Impairment and normal hepatic function. The study will be conducted in two stages. Based on the research results of moderate hepatic Impairment and matched control subjects with normal hepatic function, the sponsor will make a comprehensive analysis to decide whether it is necessary to conduct a study on the mild hepatic Impairment and matched control subjects with normal hepatic function.

Subjects with liver dysfunction must also meet all of the following conditions:

1. Chronic liver injury caused by primary liver disease (such as hepatitis B, hepatitis C, autoimmune hepatitis, alcoholic liver disease, etc.) in subjects with hepatic impairment classified as A or B by Child Pugh grading (see Appendix 3 for Child Pugh grading).
2. Researchers determine that the hepatic function status of the subjects has been stable for at least 2 months based on their clinical symptoms and other examination results available during screening (as determined by the researchers).
3. Individuals who have a stable medication regimen for treating hepatic impairment, complications, and other accompanying diseases for at least 14 days prior to taking the investigational drug, and whose medication does not require adjustment (including medication type, dosage, or frequency, except for diuretics, insulin, and other medications); Or those who have not taken medication.

Exclusion Criteria:

Individuals who have consumed a special diet (including dragon fruit, mango, grapefruit, and/or xanthine diet, chocolate) and/or consumed excessive amounts of tea, coffee, grapefruit/grapefruit juice, and/or caffeinated beverages (an average of 8 or more cups per day, 200 mL per cup) within 2 weeks prior to administration;
  8. Individuals who smoke an average of 10 or more cigarettes per day within the first 3 months of screening;
  9. Screening for alcoholics within the first 3 months, i.e. those who consume more than 14 units of alcohol per week (1 unit=360 mL of beer, 45 mL of strong liquor with an alcohol content of 40%, or 150 mL of wine) or have a positive alcohol screening result;
  10. Individuals with a history of drug use, substance abuse, or a positive urine drug test;
  11. Pregnant or lactating women, or women of childbearing age who test positive for pregnancy;
  12. Not suitable for those who undergo venipuncture or have a history of needle and blood dizziness;
  13. Other reasons why researchers believe it is not suitable for inclusion.

Subjects with normal hepatic function should be excluded if they meet any of the following exclusion criteria:

1. History of liver injury;
2. Individuals who have previously or currently suffered from any clinically 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 can interfere with the test results;
3. Abnormalities in physical examination, vital signs, laboratory tests, 12 lead electrocardiogram, chest X-ray, abdominal ultrasound, and other examinations have clinical significance as determined by the researchers;
4. Those who are positive in any index screening of hepatitis B surface antigen, hepatitis C antibody, HIV antigen/antibody or Treponema pallidum antibody;
5. Individuals who have used any prescription drugs, over-the-counter drugs, herbal medicines, or health supplements (excluding topical preparations that exert local effects) within 14 days prior to drug administration.

If a subject with hepatic impairment meets any of the following exclusion criteria, they should be excluded:

1. The subject has any of the following conditions: ① Having undergone liver transplantation in the past; ② Having undergone partial hepatectomy in the past; ③ Patients who are suspected of or diagnosed with liver cancer or other malignant tumors (except for specific cancers that have been surgically removed and completely cured, such as basal cell carcinoma or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix; except for patients with liver cancer who have received radical treatment and have no recurrence; except for patients with liver cancer at BCLC stage 0)；④ Patients with liver failure; ⑤ Those who had rupture and bleeding of esophageal and gastric varices within 3 months before screening; ⑥ Patients with biliary cirrhosis, extrahepatic biliary obstruction and other diseases, and who are deemed by the investigator as not suitable to participate in this trial;
