About this study
Official title: Baltic Post-marketing Program of PEGASYS (Peg Interferon Alpha-2a 40KD) in Patients With HBeAg-positive and HBeAg-negative Chronic Hepatitis B
This single-arm study will evaluate the efficacy and safety of peginterferon alfa-2a in treatment-naive Baltic participants with Hepatitis B envelope antigen (HBeAg)-positive chronic Hepatitis B virus (HBV). All participants will receive peginterferon alfa-2a 180 micrograms (mcg) subcutaneously once weekly. Following 48 weeks of treatment, there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is less than 100 participants.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Hepatitis B Envelope Antigen (HBeAg) Positive Participants With Hepatitis B Virus Deoxyribonucleic Acid (HBV-DNA) Less Than (<) 1,00,000 Copies Per Milliliter (Copies/mL)
HBeAg is a soluble antigen of hepatitis B virus present in the blood during acute infection, and disappear afterward but sometimes persisting in chronic disease. HBeAg positive participants were defined as those who had HBV DNA greater than (>) 1,00,000 copies/mL at baseline. This outcome measured the number of participants with HBV-DNA levels < 1,00,000 copies/mL at Week 72, who were defined as HBeAg positive at baseline.
Measured: Week 72
Number of HBeAg Negative Participants With HBV-DNA < 10,000 Copies/mL
HBeAg is a soluble antigen of hepatitis B virus present in the blood during acute infection, and disappear afterward but sometimes persisting in chronic disease. HBeAg negative participants were defined as those who had HBV DNA >10,000 copies/mL at baseline. This outcome measured the number of participants with HBV DNA <10,000 copies/mL at Week 72, who were defined as HBeAg negative at baseline.
Measured: Week 72
Secondary outcomes (6)
Number of Participants With HBV-DNA < 400 Copies/mL
Measured: Week 72
Percentage of Hepatitis B Surface Antigen (HBsAg) Negative Participants
HBsAg seroconversion was defined as the absence of HBsAg (HBsAg negative) and the presence of anti-HBs (anti-HBs positive) for HBsAg participants. Percentage of HBsAg negative participants were reported.
Measured: Week 48 and Week 72
Percentage of Anti-HBs Positive Participants
HBsAg seroconversion was defined as the absence of HBsAg (HBsAg negative) and the presence of anti-HBs (anti-HBs positive) for HbsAg participants. Percentage of Anti-HBs positive participants were reported.
Measured: Week 48 and Week 72
Mean Alanine Aminotransferase (ALT) Concentrations
Measured: Week 48 and Week 72
Percentage of HBeAg Negative Participants
HBeAg seroconversion was defined as the absence of HBeAg (HBeAg negative) and the presence of anti-HBe (anti-HBe positive) for HBeAg positive participants. Percentage of HBeAg negative participants were reported.
Measured: Week 48 and Week 72
Percentage of Anti-HBe Positive Participants
HBeAg seroconversion was defined as the absence of HBeAg (HBeAg negative) and the presence of anti-HBe (anti-HBe positive) for HBeAg participants. Percentage of Anti-HBe positive participants were reported.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Peginterferon alfa-2a in people with Hepatitis B, Chronic, run by Hoffmann-La Roche at 9 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in Lithuania, Estonia, Latvia. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 24 Oct 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Hepatitis B Envelope Antigen (HBeAg) Positive Participants With Hepatitis B Virus Deoxyribonucleic Acid (HBV-DNA) Less Than (<) 1,00,000 Copies Per Milliliter (Copies/mL) (time frame: Week 72). The study lists 2 primary outcomes in all. 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 24 Oct 2016.
