A Study to Evaluate the Safety of Hydronidone Capsules in Patients With Liver Fibrosis

Inclusion criteria

• Age ≥ 18 years at the time of signing the informed consent form (ICF), male or female.
• Patients assessed by the investigator as having chronic hepatitis B with hepatic fibrosis or fatty liver disease with fibrosis (including compensated cirrhosis) based on histology, imaging, or laboratory markers, meeting any of the following criteria:

Histologically confirmed diagnosis of hepatic fibrosis (F2 or above);

Endoscopy showing esophageal or gastric varices or ectopic gastrointestinal varices, excluding non-cirrhotic portal hypertension;

For chronic hepatitis B patients: liver imaging suggestive of fibrotic features, with liver stiffness measurement (LSM) ≥ 8.5 kPa, or Fibrosis-4 Index (FIB-4) ≥ 1.45; Or for non-alcoholic fatty liver disease patients: LSM ≥ 8.5 kPa or FIB-4 ≥ 1.3; Or for alcoholic liver disease patients: LSM ≥ 8.5 kPa.

• Subjects who agree to use effective contraception measures as specified below during their participation in the trial:

Male subjects must consistently employ highly effective contraception methods as described in Appendix 1 from the time of signing the informed consent form until at least 6 months after the last dose of the investigational product.

Female subjects participating in this trial must not be pregnant or lactating and must meet at least one of the following conditions:

• Be a woman of non-childbearing potential (WONCBP), as defined in Appendix 1;
• Be a woman of childbearing potential (WOCBP) who consistently uses highly effective contraception methods as described in Appendix 1 from the time of signing the informed consent form until at least 6 months after the last dose of the investigational product, and agrees not to donate eggs for reproductive purposes during this period.

• The patient voluntarily agrees to participate in this trial, demonstrates good compliance, and has the capacity to understand and sign the informed consent form prior to the study.

Exclusion criteria

• At screening, total bilirubin (TBIL) > 3 × upper limit of normal (ULN), or direct bilirubin (DBIL) > 2 × ULN, or alanine aminotransferase (ALT) > 3 × ULN.
• At screening, alpha-fetoprotein (AFP) > 20 μg/L.
• At screening, platelet count (PLT) ≤ 75 × 10⁹/L, or international normalized ratio (INR) > 1.5.
• History of or current clinical diagnosis of decompensated cirrhosis at screening, or imaging showing significant space-occupying lesions in the liver (intrahepatic nodules > 10 mm), or findings suggestive of malignancy.
• Diagnosis of any other malignancy within the past 5 years prior to screening, except for radically resected and non-recurrent skin basal cell carcinoma, cutaneous squamous cell carcinoma, superficial bladder cancer, carcinoma in situ of the cervix (excluding the cervical cancer cohort), localized prostate cancer, or other carcinomas in situ.
• Use of interferon within 3 months prior to screening.
• Concurrent severe diseases of the cardiovascular, pulmonary, renal, endocrine, neurological, digestive, or hematopoietic systems, or psychiatric disorders.
• Planned participation in other interventional clinical trials during the study period.
• Participation in any other clinical trials within 3 months prior to screening.
• Pregnant and/or lactating women.
• Other conditions deemed unsuitable for inclusion by the investigator.
