About this study

Official title: Mechanisms Associated With Favorable Response to Peginterferon-Alpha Add-on Therapy Following Long-term Nucleos(t)Ide Analogue Treatment in Patients With Chronic Hepatitis B

Background:

  • Chronic hepatitis B is caused by a virus that infects the liver. Cure is not possible but the virus can be controlled with the use of antiviral medicines,. Researchers think that adding a second antiviral medicine might help.
Read more

Objective:

  • To understand how peginterferon might help treat people with chronic hepatitis B. Also, to see if peginterferon is safe to use with other antiviral medications.

Eligibility:

  • Adults age 18 and older who have chronic hepatitis B and had therapy with 1 or more oral medicines for hepatitis B for at least 4 years.

Design:

  • Participants will be screened with physical exam and medical history. They will complete health questionnaires about their levels of fatigue and pain. They will have blood and urine tests. They may have an eye exam.
  • Participants also will have a Fibroscan. A test to measure how stiff your liver is.
  • Eligible participants will have a liver biopsy. Blood will be drawn.
  • Participants will be admitted to the NIH Clinical Center. They will be injected with the study drug. Then they will have a second liver biopsy. They will be discharged 24 hours later.
  • Participants will give themselves study drug injections under the skin weekly for 24 weeks.
  • Participants will have 5 clinic visits during the 24-week treatment period. Then they will have follow-up visits every 12 weeks for 48 weeks.
  • During visits, participants may have a physical exam and medical history. They may have blood and urine tests. They may have a Fibroscan and complete questionnaires. At the final visit, they will also have a Fibroscan.
Read the detailed description

Chronic hepatitis B virus (HBV) infection is a leading cause of liver associated morbidity and mortality. Currently available first-line therapies for treatment of chronic hepatitis B include pegylated interferon-alpha and the nucleos(t)ide analogues (NUCs) entecavir and tenofovir. These were shown to effectively suppress viral replication, but their ability to induce durable off-treatment response is limited to a small subset of patients. Combination treatment with peginterferon and NUCs has been attempted in several randomized controlled trials, with no apparent advantage over either agent given alone. In these studies however, treatment with peginterferon was initiated either simultaneously or shortly after NUCs administration. The efficacy of peginterferon following long-term viral suppression with NUCs was only tested in one small pilot study, nevertheless showing 60% hepatitis B s antigen (HBsAg) loss rate.

The underlying mechanisms responsible for improved efficacy of peginterferon in this setting are unknown and warrant further investigation. In this single arm study we propose to evaluate the efficacy and mechanisms associated with response to peginterferon add-on therapy following a minimum of 192 weeks of viral suppression induced by NUCs in a group of chronic HBV infected patients. Sixty patients with either hepatitis B e antigen (HBeAg) positive (n=30) or negative (n=30) chronic HBV infection will be enrolled to this study. After medical evaluation and pretreatment liver biopsy, treatment with subcutaneous injections of pegylated interferon alpha-2a 180 g per week will be given for a total of 24 weeks, followed by an off-treatment evaluation period of 48 weeks. A second liver biopsy will be performed six hours following the first peginterferon injection. Primary end-point for this study will be the change in interferon-stimulated-genes response before and after first interferon injection in responders versus non-responders to treatment. The responsiveness to IFN-based therapy of treatment responders vs nonresponders will additionally be evaluated by studying intrahepatic and peripheral blood natural killer cells. The study will also assess HBeAg and HBsAg loss and seroconversion rates in comparison to historical controls treated with either peginterferon or NUCs monotherapy. Finally, we will assess whether treatment responders develop an HBV-specific T cell response similar in quantity and quality to that of patients who spontaneously resolve HBV infection.

What is being measured

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

  1. Change in Interferon-stimulated-gene (ISG) Expression

    Change in level of ISG expression before and after 1st peginterferon injection

    Measured: 6 hours after first injection of peginterferon

Secondary outcomes (4)
  1. Hepatitis B e Antigen (HBeAg) Loss

    Proportion of HBeAg positive patients showing eAg loss at end of treatment, and 24 and 48 weeks off peginterferon treatment.

    Measured: End of treatment, 24 weeks, and 48 weeks

  2. Hepatitis B s Antigen (HBsAg) Loss

    Proportion of HBsAg positive patients showing sAG loss at end of treatment and 24 and 48 weeks off peginterferon treatment

    Measured: End of treatment, 24 weeks, and 48 weeks

  3. Change in Natural Killer (NK) Cell Frequency

    NK cell frequency is calculated as 100*(NK cells)/(mononuclear cells). Changes are calculated by subtracting baseline from 6 hours after first peginterferon injection.

    Measured: 6 hours after first injection of peginterferon and baseline

  4. Change in Natural Killer (NK) Cell Degranulation

    NK cell degranulation is calculated as 100*(degranulated NK cells)/(NK cells). Changes are calculated by subtracting baseline from 6 hours after first peginterferon injection.

    Measured: 6 hours after first injection of peginterferon and baseline

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 12 inclusion and 21 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 4 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 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?

Yes. Results are posted in the registry (first posted 28 Aug 2019). 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?

Change in Interferon-stimulated-gene (ISG) Expression (time frame: 6 hours after first injection of peginterferon). 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 NCT02364336, 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 4 Sep 2019.
