A Phase IIIc Clinical Study to Evaluate the Long-term Treatment of Hydronidone Capsules for Liver Fibrosis in Patients With Chronic Hepatitis B.

February 12, 2026 updated by: Beijing Continent Pharmaceutical Co, Ltd.

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase IIIc Clinical Study Evaluating the Long-term Treatment of Hepatic Fibrosis in Chronic Hepatitis B With Hydronidone Capsules.

This study is conducted as a randomized, double-blind, placebo-controlled, multicenter clinical trial on a background of entecavir therapy. It aims to evaluate the clinical benefits of Hydronidone Capsules in patients with liver fibrosis due to chronic hepatitis B. The study consists of a Screening/Baseline Period (4 weeks) and a Dosing/Observation Period (planned duration of 5 years, including a 52-week primary treatment phase and a 208-week long-term treatment phase).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of Clinical Endpoint Events
Time Frame: From the first dose administration to the end of the treatment period (Week 261).
The clinical endpoint event is a composite event, which includes progression to complications of decompensated cirrhosis (such as ascites, esophageal and gastric variceal bleeding, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatopulmonary syndrome, hepatic encephalopathy, portal vein thrombosis, and cirrhotic cardiomyopathy, etc.), hepatocellular carcinoma, liver transplantation, and liver disease-related death/all-cause death. The time of event occurrence is determined by whichever occurs first, and the occurrence of any of these events constitutes a clinical endpoint event.
From the first dose administration to the end of the treatment period (Week 261).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
