About this study
Official title: An Observational, Multi-Center, Cohort Study Evaluating the Antiviral Efficacy, Safety, and Tolerability in Korean Patients With Chronic Hepatitis B (CHB) Receiving Pegylated Interferon-alpha 2a (Pegasys®): TRACES STUDY
The current proposed study aims to bring answers following issues: the antiviral efficacy and safety profiles in Korean Chronic Hepatitis B (CHB) patients who are mostly infected with solely genotype C HBV, a proper duration of Pegasys® therapy post-treatment durability or accumulation of HBeAg seroconversion/HBsAg loss, preventable effect on long-term disease progression to liver cirrhosis and liver cancer. In addition, this study aims to collect more data on the efficacy and safety in a real-life clinical setting of Pegasys® therapy in patients with CHB.
Read the detailed description
- Korea is known to be an endemic area for HBV infection. Some studies have reported that more than 95% of patients in Korea with chronic HBV have genotype C infection.
- Compared with other genotypes, genotype C is associated with increased viral loads, higher histologic activity, more severe acute exacerbations, a longer viral clearance phase and worse antiviral response to peg-interferon therapy.
- Long-term nucleos(t)ide analogue (NA) therapy is recommended for chronic hepatitis B (CHB) patients with compensated and decompensated liver disease. However, a possibility of cessation of antiviral treatment with oral NAs is unlikely due to rebound of HBV DNA levels after termination of NAs administration. In addition, NA therapy has been reported to have lower chance of HBsAg seroclearance compared to that with immunomodulatory agents such as peginterferon.
- Pegasys® has been proved to induce HBsAg loss, which is the closest to cure of disease. However, a better understanding of HBV treatment with Pegasys® in the real-life clinical setting in Korea can be helpful for decision of treatment strategy in the future. Asian experience with Pegasys® therapy in CHB is limited. Study populations of investigator-initiated trials consist of selected group with smaller number of Korean patients. Therefore, long-term efficacy and safety data in real practice with Pegasys® treatment in both HBeAg-positive and -negative Korean patients are necessary.
- In addition, the current proposed collected data study may be helpful to bring answers to many unresolved issues: the antiviral efficacy and safety profiles in Korean CHB patients who are mostly infected with solely genotype C HBV, a proper duration of Pegasys® therapy post-treatment durability or accumulation of HBeAg seroconversion/HBsAg loss, preventable effect on long-term disease progression to liver cirrhosis and liver cancer. In addition, this study aims to collect more data on the efficacy and safety in a real-life clinical setting of Pegasys® therapy in patients with CHB.

Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
HBsAg loss or appearance of anti-HBs antibody in treatment-naïve Korean CHB patients treated with Pegasys (time frame: 2015 (up to 3 years)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2016.
