An Observational Cohort Study of Clinical Outcomes After Antiviral Treatment of Chronic Hepatitis C

March 6, 2020 updated by: Yao Xie, Beijing Ditan Hospital

An Observational Cohort Study of Clinical Outcomes After Antiviral Treatment of Chronic Hepatitis C Patients

This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. In the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, chronic hepatitis C patients who were treated with interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ), and the baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment were collected, and follow-up observations of patients were carried out for every 3-6 months. The clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) were collected during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.

Detailed Description

This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. Enrolled in the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, via interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ) For patients with chronic hepatitis C treated, collect baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment, and follow-up observations of patients enrolled every 3-6 months. Collect clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.

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.

Measure Description
Time Frame
Incidence of liver cancer
Time Frame: 144 weeks after withdrawal
Incidence of liver cancer after chronic hepatitis C antiviral treatment
144 weeks after withdrawal
Incidence of decompensated cirrhosis
Time Frame: 144 weeks after withdrawal
Incidence of decompensated cirrhosis after chronic hepatitis C antiviral treatment
144 weeks after withdrawal

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.
