The Phase Ⅰd Clinical Trial of Hydronidone Capsules

Clinical Pharmacokinetic Study of Hydronione Capsules in Healthy Chinese Subjects (Ⅰd)

Based on the Phase I (Ia, Ib, Ic) clinical pharmacokinetic study of Hydronidone Capsules, a clinical pharmacokinetic trial of Hydronidone Capsules (specification: 30 mg/capsule) was conducted, including single-dose administration, multiple-dose administration, and a food-effect study. The aim was to investigate the safety, tolerability, and pharmacokinetic characteristics of higher doses of Hydronidone Capsules (specification: 30 mg/capsule) in healthy subjects, in preparation for future expansion of indications.
