About this study

Official title: Clinical Trial of Entecavir/Pegylated Interferon in Immune Tolerant Children With Chronic HBV Infection (HBRN)

The purpose of this study is to determine the safety and efficacy of treatment using a combination of drugs (entecavir and pegylated interferon) in children ages 3-<18 years old with immunotolerant chronic hepatitis B.

Read the detailed description

This single arm treatment study was conducted by the pediatric centers within the National Institute of Diabetes Digestive and Kidney Diseases (NIDDK)-sponsored Hepatitis B Research Network (HBRN). Children age 3-<18 years with immunotolerant chronic hepatitis B (CHB) infection who fulfilled the entry criteria received entecavir as monotherapy for 8 weeks and then combination therapy with entecavir and pegylated interferon by weekly subcutaneous injection until week 48. Children were to be followed for 48 weeks after discontinuation of therapy (week 96 for those who completed 48 weeks of treatment).

Assessment was undertaken at baseline, weeks 4, 8, 10, 12, 14, \& 16, then every 4 weeks until week 48, and then 4, 8, 12, 24,36, and 48 weeks following treatment discontinuation corresponding to weeks 52, 56, 60, 72, 84 and 96 for those who received treatment for 48 weeks. Blood work was drawn to measure markers of viral and liver disease status and for research biospecimen banking.

Participants were to receive therapy until week 48 and enter 48 weeks of follow-up thereafter. Participants who experienced a sustained elevation of alanine aminotransferase (ALT) were eligible to receive treatment as recommended by their hepatologist and continued to complete the study protocol.

What is being measured

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

  1. Proportion of Participants With Hepatitis B e Antigen (HBeAg) Loss & Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) Levels ≤1,000 International Units (IU) Per Milliliter (mL)

    Measured: End of follow-up (up to 96 weeks)

  2. Incidence of Adverse Events (AEs) Per Person-Year

    The number of AEs includes both AEs and Serious Adverse Events (SAEs). The incidence is calculated as the number of AEs divided by the number of person-years of observation, which is the sum, across all participants, of the number of years between the start of treatment and the end of treatment, or the end of follow-up, respectively.

    Measured: From first treatment to the end of treatment (up to 48 weeks) and the end of follow-up (up to 96 weeks)

  3. Incidence of Serious Adverse Events (SAEs) Per Person-Year

    The incidence is calculated as the number of SAEs divided by the number of person-years of observation, which is the sum, across all participants, of the number of years between the start of treatment and the end of treatment, or the end of follow-up, respectively.

    Measured: From first treatment to the end of treatment (up to 48 weeks) and the end of follow-up (up to 96 weeks)

  16. Growth Measures: Z-scores Weight, Height, and Body Mass Index

    A child's Z-score is the number of standard deviations that the child is from the average of children of the same sex and age from a reference population. The reference population is provided in the 2000 Centers for Disease Control and Prevention (CDC) growth charts. Positive Z scores mean the growth measure (weight, height, or body mass index) is above the average, negative Z scores mean the growth measure is below the average.

    Measured: End of treatment (up to 48 weeks)

  17. Growth Measures: Z-scores Weight, Height, and Body Mass Index

    Measured: End of follow-up (up to 96 weeks)

  18. Tanner Stages of Physical Growth

    The Tanner Stage questionnaire is only completed by participants 8 years of age and older. The copyrighted form includes pictures and descriptions. Girls selected the picture closest to their self-perceived breast growth from among 5 stages of breast growth and boys did the same for testes, scrotum, and penis growth.

    Boys: I-prepubertal; II-enlargement of scrotum and testes; III-enlargement of the penis and further growth of testes; IV- increased size of penis with growth in breadth and development of glans, testes, and scrotum larger, scrotum skin darker; V- adult genitalia.

    Girls: I-prepubertal; II-breast bud stage with the elevation of breast and papilla and enlargement of the areola; III-further enlargement of breast and areola, no separation of their contour; IV-areola and papilla form a secondary mound above the level of the breast; V: mature adult stage.

    There is no "better" or "worse" outcome. They are self-assessed descriptive measures of physical growth.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Entecavir and peginterferon in people with Hepatitis B, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at 7 sites in 2 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 9 inclusion and 24 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 26 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States, Canada. 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 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 3 Jul 2018). 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?

Proportion of Participants With Hepatitis B e Antigen (HBeAg) Loss & Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) Levels ≤1,000 International Units (IU) Per Milliliter (mL) (time frame: End of follow-up (up to 96 weeks)). The study lists 3 primary outcomes in all. 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 NCT01368497, which also lists 1 linked publication.

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 26 May 2022.
