October 18, 2018 updated by: Qin Ning

A Prospective, Multicentre Observational Follow-up Study of PegIFN Treatment Sustained Response in Nucleoside Experienced Patients With Chronic Hepatitis B (the OCEAN Study)

This is a prospective, multicentre observational follow-up study of PegIFN treatment unstained response in nucleoside experienced patients with Chronic Hepatitis B.Patients will join this study after finished following clinical trail about A Study of Combination or Sequential Treatment With PEGASYS (Peginterferon Alfa-2a) and Entecavir in Patients With HBeAg Positive Chronic Hepatitis B(OSST trail),A Real-World Study of Pegylated Interferon In Nucleoside-treated Patients With Chronic Hepatitis B (COST study), Combination Therapy With Interferon Plus Interleukin 2 and Hepatitis B Vaccine in Chronic Hepatitis B Patients(Endeavor study),A Prospective Clinical Trial in Chronic Hepatitis B Patients Nucleotide Analogues Experienced (Anchor A Study),Sequential/Combination Therapy in Nucleoside or Nucleotide Analogue (NA)-Suppressed Chronic Hepatitis B Patients (NPGV study).We plan to compare the HBsAg negative rate and maintenance rate,the occurrence of liver cirrhosis and the occurrence rate of hepatocellular carcinoma(HCC) related to hepatitis B virus(HBV) within five years between interferon group (including interferon alone or interferon combined with other drugs) and nucleoside analogues.Patients were divided into two groups based on whether they received interferon or not.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Patients who treated with nucleoside analogs, and previously took part in the OSST,COST,Endeavor, Anchor NPGV studies, were included in the observational study after they finished. The patients entered the following two observation groups based on previous studies: Group A: formerly interferon group (including interferon alone or interferon combined with other drugs); Group B: formerly nucleoside analogue treatment group. Each group was followed for five years.All patients were followed up for physical examination (vital signs, whole body examination) and laboratory assessment (HBsAg quantification, HBeAg quantification, HBV DNA, HBV immunology marker, blood routine, blood biochemistry, alpha fetoprotein, Fibroscan, liver Doppler) in every six month.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
