What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 150 participants in total. It began in 2026-04-14 with a primary completion date of 2026-07-30.

Brief Summary

This trial employs a single-arm, open-label, multicenter clinical trial design. All study participants who meet the inclusion/exclusion criteria will receive Hydronidone treatment for 4 weeks. The study includes a screening period (up to 21 days) to assess the eligibility of participants. Eligible participants will enter the treatment period and receive Hydronidone capsules at a dosage of 270 mg TID (30 mg/capsule, 3 capsules each time, three times daily, taken orally half an hour before meals) for 28 consecutive days. Participants will return for a follow-up visit on Day 28 (±3 days) after the first dose for safety assessments. All adverse events (AEs) and concomitant medications occurring during the study period must be recorded. After the treatment period, participants will enter a follow-up period to monitor any delayed adverse events. Participants who complete the final follow-up visit are considered to have completed the study. Throughout the study, participants must maintain the stability of all their pre-existing treatment regimens, including antiviral therapy and medications for other comorbid conditions.

Eligibility Criteria

Inclusion Criteria: * Age 18 to 70 years (inclusive of 18 and 70 years old, based on the date of signing the informed consent form), regardless of gender. * History of chronic hepatitis B and/or Hepatitis B surface antigen (HBsAg) positive for ≥6 months. * Diagnosed with chronic hepatitis B-related fibrosis by the investigator, meeting any of the following criteria: 1.
