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.

Outcome Measures

Primary Outcomes (2)

• Incidence of adverse events (AEs) and serious adverse events (SAEs).

  Adverse Event (AE) refers to any untoward and unintended medical occurrence experienced by a trial participant during treatment or clinical investigation, regardless of causal relationship to the investigational product. Serious Adverse Event (SAE) is a subset of AE that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, causes persistent or significant disability/incapacity, leads to congenital anomaly/birth defect, or is judged medically important by the investigator. According to the Common Terminology Criteria for Adverse Events, Version 6.0, pulmonary injury is graded, with higher grades indicating more severe symptoms.
