Chronic Hepatitis B-related Liver Fibrosis

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.

According to the "Technical Guidelines for Radioactive Labeled Human Mass Balance Studies" issued by the NMPA, human mass balance studies are an important component of clinical pharmacology research for innovative drugs, and it is recommended that mass balance studies be conducted for all new molecular entities. Therefore, to further clarify the absorption, metabolism, and excretion characteristics of Hydronidone in the human body, a \[¹⁴C\] Hydronidone mass balance study is planned in Chinese healthy adult male participants. This study aims to reveal the pharmacokinetic characteristics of Hydronidone and provide a reference for the rational use of the drug.
