About this study

Official title: Efficacy and Safety of PegIntron Plus Ribavirin for Treatment of Chronic Hepatitis C Infection in HIV-Infected Persons Not Previously Treated With Interferon

In this study, adult Indonesian subjects with human immunodeficiency virus (HIV) coinfected with chronic hepatitis C (CHC) will be given peginterferon alfa-2b (PEG-IFN) plus ribavirin (RBV) combination therapy. The efficacy rate (sustained virologic response, end of treatment virologic response, and sustained biochemical response), the subject morbidity rate as caused by other opportunistic infection (eg, bacterial pneumonia, tuberculosis, and other bacterial infection), and the safety and tolerability of this combination therapy will be examined.

Being tested
Peginterferon alfa-2b (SCH 054031), Ribavirin (SCH 018908)

What participants receive

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

  • Peginterferon alfa-2b (SCH 054031)Biological

    Also called PegIntron

    Subjects will be given peginterferon alfa-2b (PEG-IFN) subcutaneously, at a dose of 1.5 ug/kg weekly. Treatment duration will be 48 weeks for subjects with Hepatitis C Virus (HCV) genotype 1 and 24 weeks for subjects with HCV genotype 2 or 3 and baseline Hepatitis C Virus-ribonucleic acid (HCV-RNA) below 800,000 IU/mL.

  • Ribavirin (SCH 018908)Drug

    Also called Rebetol

    Subjects will be given ribavirin 800 mg/day orally(PO) when body weight is <65 kg, 1000 mg/day when body weight is between 65 kg and 85 kg, and 1200 mg/day when body weight is >85 kg. Treatment duration will be 48 weeks for subjects with HCV genotype 1 and 24 weeks for subjects with HCV genotype 2 or 3 and baseline HCV-RNA below 800,000 IU/mL.

What is being measured

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

  1. Number of Participants Who Achieved Sustained Virologic Response (SVR)

    Treatment duration for genotype 1 participants was 48 weeks. Treatment duration for genotypes 2 \& 3 participants who had baseline hepatitis c virus ribonucleic acid [HCV-RNA] <800,000 IU/mL was 24 weeks.

    SVR was defined as plasma HCV RNA level below lower level of quanitation at the end of 24 weeks follow-up (week 48 or 72).

    The study was terminated due to low enrollment. This analysis was not performed.

    Measured: Week 48 or Week 72 (depending on duration of treatment)

  2. Number of Participants Who Achieved Virologic Response (VR)

    Treatment duration for genotype 1 participants was 48 weeks. Treatment duration for genotypes 2 \& 3 participants who had baseline hepatitis c virus ribonucleic acid [HCV-RNA] <800,000 IU/mL was 24 weeks.

    The study was terminated due to low enrollment. This analysis was not performed.

    Measured: 24 Weeks or 48 Weeks (depending on duration of treatment, which was either 24 or 48 weeks)

  3. Number of Participants Who Achieved Sustained Biochemical Response (SBR)

    Treatment duration for genotype 1 participants was 48 weeks. Treatment duration for genotypes 2 \& 3 participants who had baseline hepatitis c virus ribonucleic acid [HCV-RNA] <800,000 IU/mL was 24 weeks.

    SBR was defined as the presence of normal alanine aminotransferase (ALT) values at the end of 24 weeks follow-up (week 48 or 72).

    The study was terminated due to low enrollment. This analysis was not performed.

    Measured: Week 48 or Week 72 (depending on duration of treatment, which was either 24 or 48 weeks)

Secondary outcomes (3)
  1. Number of Participants Experiencing Opportunistic Infection

    The study was terminated due to low enrollment. This analysis was not performed.

    Measured: Throughout the study (up to 72 weeks)

  2. Number of Participants Who Died

    Measured: Throughout the study (up to 72 weeks)

  3. Number of Participants Experiencing Adverse Events

    An adverse event was defined as any untoward medical occurrence in a subject administered a pharmaceutical product, biologic (at any dose), or medical device, which did not necessarily have a causal relationship with the treatment.

    Measured: Throughout the study (up to 72 weeks)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Peginterferon alfa-2b (SCH 054031) and Ribavirin (SCH 018908) in people with Hepatitis C, Chronic and Hepacivirus, 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 20 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 Apr 2017. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 30 Jan 2012). 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?

Number of Participants Who Achieved Sustained Virologic Response (SVR) (time frame: Week 48 or Week 72 (depending on duration of treatment)). 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 6 Apr 2017.
