Brief Summary

The proposed indication for Hydronidone Capsules is chronic hepatitis B-associated liver fibrosis, which in clinical practice typically requires concomitant use with antiviral agents for chronic hepatitis B. The commonly used chronic hepatitis B antiviral agents include Entecavir, Tenofovir Disoproxil Fumarate (TDF), Tenofovir Alafenamide (TAF), and Tenofovir Amibufenamide (TMF).

This study aims to evaluate the drug-drug interaction (DDI) of Hydronidone Capsules 90 mg with Entecavir, Tenofovir Disoproxil Fumarate (TDF), Tenofovir Alafenamide (TAF), and Tenofovir Amibufenamide (TMF) respectively in healthy participants, to inform the preparation of post-marketing labeling and the development of concomitant dosing regimens in clinical practice.

Study Groups

Queue 1: Drug-Drug Interaction Study of Hydronidone Capsules and Entecavir

Within each cohort, the study flow for enrolled subjects comprises three dosing periods: Period 1 consists of hydronidone capsules administered alone for 5 consecutive days; Period 2 consists of the chronic hepatitis B antiviral agent administered alone for 7 or 10 consecutive days; and Period 3 consists of concomitant administration of hydronidone capsules and the antiviral agent for 5 consecutive days. Subjects may be discharged from the study upon completion of the safety follow-up.
