About this study

Official title: A Multicenter, Prospective, Observational, Non-Interventional Cohort Study Evaluating Sustained Response in Subjects With HBeAg Positive Chronic Hepatitis B Receiving Therapy With Pegasys (Peginterferon Alfa-2a) in Vietnam

This prospective, multicenter, observational study will evaluate the sustained response in patients with HBeAg positive chronic hepatitis B who are treated with Pegasys according to standard of care and in line with the current local labeling in routine clinical practice in Vietnam. Eligible patients will be followed for the duration of their treatment and for up to 2 years thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Suppression of Hepatitis B Virus Deoxyribonucleic Acid To <2,000 IU/mL at 6 Months After End of Treatment

    A participant was considered to have achieved suppression of Hepatitis B Virus Deoxyribonucleic Acid (HBV DNA) to <2,000 International Units Per Milliliter (IU/mL) if the HBV DNA measurement is lower than 2,000 IU/mL.

    Measured: 6 months

  2. Percentage of Participants Who Become Hepatitis B Envelope Antigen-Negative and Anti-HBe-Positive During Treatment and at 6 and 12 Months After End of Treatment

    HBeAg is a protein from the Hepatitis B virus that circulates in infected blood when the virus is actively replicating. The presence of HBeAg suggests that the participant is infectious and is able to spread the virus to other people. HBeAg-negative hepatitis B is a form of the virus that does not cause infected cells to secrete HBeAg. Participant can be infected with the HBeAg-negative form of the virus from the beginning, or the viral mutation can emerge later in the course of infection in participant initially infected with the HBeAg-positive form of the virus.

    Measured: 12 months

Secondary outcomes (6)
  1. Percentage of Participants With Suppression of Hepatitis B Virus Deoxyribonucleic Acid To <2,000 IU/mL During the Observation Period

    A participant was considered to have achieved suppression of HBV DNA to <2,000 IU/mL if the HBV DNA measurement is lower than 2,000 IU/mL.

    Measured: Up to 24 months

  2. Percentage of Participants With Loss of Hepatitis B Envelope Antigen During the Observation Period

    Loss of HBeAg is defined as the absence of HBeAg. A participant was considered to have achieved HBeAg loss if the HBeAg measurement was reported as (a) 'NEGATIVE' or (b) a quantitative result was lower than the reported lower detection limit.

    Measured: Up to 24 months

  3. Percentage of Participants With Hepatitis B Envelope Antigen Seroconversion and Hepatitis B Virus Deoxyribonucleic Acid Suppression (<2,000 IU/mL) During the Observation Period

    HBeAg seroconversion is defined as the absence of HBeAg and the presence of antibody to hepatitis B antigen (anti-HBe) . A participant was considered to have achieved suppression of HBV DNA to <2,000 IU/mL if the HBV DNA measurement is lower than 2,000 IU/mL.

    Measured: Up to 24 months

  4. Percentage of Participants Who Become Hepatitis B Envelope Antigen Negative During the Observation Period

    HBeAg is a protein from the hepatitis B virus that circulates in infected blood when the virus is actively replicating. The presence of HBeAg suggests that the participant is infectious and is able to spread the virus to other people. HBeAg-negative hepatitis B is a form of the virus that does not cause infected cells to secrete HBeAg. Participant can be infected with the HBeAg-negative form of the virus from the beginning, or the viral mutation can emerge later in the course of infection in participant initially infected with the HBeAg-positive form of the virus.

    Measured: Up to 24 months

  5. Incidence of Normalization of Serum Alanine Transaminase

    Normalization of alanine transaminase (ALT) values means that ALT values out of the normal range returned to within the normal range.

    Measured: Up to 24 months

  6. Number of Participants With Incidence of Adverse Events

    An AE is any untoward medical occurrence in a patient or clinical investigation patient administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Hepatitis B, Chronic, run by Hoffmann-La Roche at 3 sites in Vietnam.

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 5 inclusion and 6 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: stopped early, as of the sponsor's last update on 22 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Vietnam. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Jun 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?

Percentage of Participants With Suppression of Hepatitis B Virus Deoxyribonucleic Acid To <2,000 IU/mL at 6 Months After End of Treatment (time frame: 6 months). 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 22 Jun 2016.
