What is being measured

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

  1. Percentage of HBeAg(+) Participants Achieving HBeAg Seroconversion at 24 Weeks Post-treatment

    Blood samples were drawn to assess the participant's seroconversion status at Follow-up (FU) Week 24. HBeAg seroconversion was defined as loss of HBeAg in HBeAg(+) participants and development of antibody to HBeAg.

    Measured: FU Week 24 (Study Week 72)

  2. Percentage of HBeAg(-) Participants Achieving Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) Levels <2000 IU/mL at 24 Weeks Post-treatment

    The Roche COBAS TaqMan HBV-(High Pure System Assay) was used to measure HBV DNA in blood samples of HBeAg(-) participants. The percentage of HBeAg(-) participants with HBV DNA <2000 IU/mL at 24 weeks post-treatment was reported.

    Measured: FU Week 24 (Study Week 72)

Secondary outcomes (3)
  1. Percentage of HBeAg(+) Participants Achieving HBV DNA <2000 IU/mL at 24 Weeks Post-treatment

    The Roche COBAS TaqMan HBV-(High Pure System Assay) was used to measure HBV DNA in blood samples of HBeAg(+)participants. The percentage of HBeAg(+) participants with HBV DNA <2000 IU/mL at 24 weeks post-treatment was reported.

    Measured: FU Week 24 (Study Week 72)

  2. Percentage of HBeAg(+) and HBeAg(-) Participants Achieving Alanine Aminotransferase (ALT) Normalization at 24 Weeks Post-treatment

    ALT normalization is a desired goal of HBV treatment, which is defined as having abnormal ALT levels at baseline and subsequently normal ALT levels after receiving treatment, where normal is defined as ≤ 1x the upper limit of normal (ULN). The percentage of HBeAg(+) and HBeAg(-) participants achieving ALT normalization at 24 weeks post-treatment was reported.

    Measured: FU Week 24 (Study Week 72)

  3. Percentage of HBeAg(+) Participants Achieving the Combined Response of HBeAg Seroconversion and HBV DNA <2000 IU/mL at 24 Weeks Post-treatment

    HBeAg seroconversion was defined as loss of HBeAg in HBeAg(+) participants and development of antibody to HBeAg. HBV DNA levels in blood were measured by the Roche COBAS TaqMan HBV-(High Pure System Assay). The percentage of HBeAg(+) participants with the combined response of achieving both HBeAg conversion and HBV DNA levels <2000 IU/mL at 24 weeks post-treatment was reported.

    Measured: FU Week 24 (Study Week 72)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing PEG-Intron™ and PEGASYS™ in people with Hepatitis B, Chronic, run by Merck Sharp & Dohme LLC.

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 10 inclusion and 15 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 27 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 12 Jan 2017). 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 HBeAg(+) Participants Achieving HBeAg Seroconversion at 24 Weeks Post-treatment (time frame: FU Week 24 (Study 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 27 Aug 2018.
