About this study

Official title: A Pharmacokinetic/Pharmacodynamic Evaluation of ABF656 in Subjects With Chronic Hepatitis B, e Ag+, Infection.

This study will assess the efficacy of ABF656 in chronic hepatitis B characterized by HBeAg positivity. The study is designed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase 3 trials. The trial is also designed to generate the PK data in hepatitis B patients to satisfy regulatory requirements in China.

What is being measured

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

  1. Evaluate the safety, tolerability and pharmacodynamic effect of various doses of albinterferon alfa-2b in hepatitis B patients on seroconversion of hepatitis markers. Measure: Clinical laboratory. HBV DNA level and HBeAg seroconversion rate.

    Measured: 48 weeks

Secondary outcomes (1)
  1. Evaluate the pharmacokinetics at different doses of albinterferon alfa-2b in patients with chronic hepatitis B infection. Measure: Serum concentration of albinterferon alfa-2b

    Measured: up to 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing albinterferon alfa-2b and Pegasys® in people with Chronic Hepatitis B, run by Novartis Pharmaceuticals at 12 sites in 5 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 9 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 6 Jan 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Poland, Taiwan, Thailand, Hong Kong, China. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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?

Evaluate the safety, tolerability and pharmacodynamic effect of various doses of albinterferon alfa-2b in hepatitis B patients on seroconversion of hepatitis markers. Measure: Clinical laboratory. HBV DNA level and HBeAg seroconversion rate. (time frame: 48 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00964665, which also lists 2 linked publications.

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 6 Jan 2011.
