About this study

Official title: A Phase 3 Study to Assess the Efficacy and Safety of Boceprevir in Combination With Peginterferon Alfa-2b Plus Ribavirin in Pediatric Subjects With Chronic Hepatitis C Genotype 1

This is a three-part (Part A, Part B, and Part C), open-label, multicenter study of boceprevir in pediatric participants with chronic hepatitis C (CHC) genotype 1 (GT1). In Part A and Part B, efficacy and safety will be evaluated in participants with CHC GT1 who are non-cirrhotic, treatment naïves (Part A) or who are non-cirrhotic, treatment failures to (peg)interferon/ribavirin or who are cirrhotics (whether treatment naïve or treatment failure) (Part B). Part C is long-term follow up and no study treatment will be administered during this period, but participants who do not achieve viral clearance will be allowed to receive other treatments for CHC.

Being tested
Boceprevir, Peginterferon alpha-2b, Ribavirin, Peginterferon alfa-2b

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BoceprevirDrug

    Also called Victrelis®, SCH 503034

    Boceprevir will be administered orally at a dose of 11.4 mg/kg three-times daily (TID) for 24 weeks. The boceprevir dose will be calculated based on 11.4 mg/kg and will then be rounded to the nearest 200-mg value for subjects in the oldest age group, or to the nearest 100-mg or 200-mg value for the subjects in the two youngest age groups.

  • Peginterferon alpha-2bDrug

    Peginterferon alpha-2b will be administered subcutaneously at a dose of 60 μg/m^2 once weekly (QW) for 24 weeks.

  • RibavirinDrug

    Also called Copegus®, Rebetol®, RibaTab®, Ribasphere®

    The dose of ribavirin will be approximately 15 mg/kg/day administered orally in two divided doses (twice daily [BID]) for 24 weeks.

  • BoceprevirDrug

    Boceprevir will be administered orally at a dose of 11.4 mg/kg three-times daily (TID) for up to 48 weeks. The boceprevir dose will be calculated based on 11.4 mg/kg and will then be rounded to the nearest 200-mg value for subjects in the oldest age group, or to the nearest 100-mg or 200-mg value for the subjects in the two youngest age groups.

  • Peginterferon alfa-2bDrug

    Also called Pegintron®, Sylatron®

    Peginterferon alpha-2b will be administered subcutaneously at a dose of 60 μg/m^2 once weekly (QW) for 48 weeks.

  • RibavirinDrug

    Also called Copegus®, Rebetol®, RibaTab®, Ribasphere®

    Drug: Ribavirin

    The dose of ribavirin will be approximately 15 mg/kg/day administered orally in two divided doses (twice daily [BID]) for 48 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Boceprevir, Peginterferon alpha-2b and Ribavirin in people with Chronic Hepatitis C, 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 9 inclusion and 23 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: withdrawn, as of the sponsor's last update on 29 Jan 2021. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Participants Achieving Sustained Viral Response (SVR) at Follow-Up Week 24 in Study Part A (time frame: Follow-Up Week 24). 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?
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 29 Jan 2021.
