About this study

Official title: An Open, Randomized, Multicentre Trial to Evaluate Efficacy and Safety of a 24-week Course of PEG-Interferon Alpha-2b Versus a 12-week Course of PEG-Interferon Alpha-2b Alone or Plus Ribavirin in Patients With Acute Hepatitis C

The objective of this study is to evaluate the efficacy of three regimens of pegylated interferon-alfa 2b (PEG-IFN) either as monotherapy or in combination with ribavirin in participants with acute hepatitis C. After 12 weeks of observation from disease onset, participants will receive one of the following regimens: (1) a 24-week course of PEG-IFN monotherapy (PEG-IFN 24); or (2) a 12-week course of PEG-IFN monotherapy (PEG-IFN-12); or (3) a 12-week course of PEG-IFN in combination with ribavirin (PEG-IFN + RVB 12). After the treatment period, participants will enter a 12-month follow-up.

What is being measured

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

  1. Number of Participants With Sustained Response (SR) at the End of the 6-month Follow-up Period

    SR was defined as serum Hepatitis C Virus (HCV RNA) level at the end of 6-month follow-up below 15 IU/mL.

    Measured: Evaluated at the end of 6 months

Secondary outcomes (5)
  1. Virologic Response at the End of Treatment Follow-up (ETR)

    ETR was achieved if serum HCV RNA level at the end of 12 or 24 weeks

    treatment (depending on treatment arm) was <15 IU/mL.

    Measured: At the end of treatment (either 12 weeks or 24 weeks depending on randomization).

  2. Virologic Response at 12 Months Post-treatment Follow-up (Long-term Response, [LTR]).

    LTR was obtained if serum HCV RNA level at the end of 12-month follow-up was <15 IU/mL.

    Measured: At 12 months post-treatment (treatment period either 12 weeks or 24 weeks depending on randomization).

  3. Number of Participants Presenting With Alanine Transferase (ALT) Level Normalization

    ALT normalization was used as a measure of biochemical response to treatment. ALT levels were assessed at each study visit by the local laboratory, and efficacy measurements at the end of treatment, at 6 and 12 months post treatment follow-up were reported.

    Measured: Evaluated at end of treatment (either 12 weeks or 24 weeks, depending on randomization), at 6-month follow-up visit, or at 12-month follow-up visit.

  4. Number of Participants With Rapid Virologic Response (RVR)

    Participants were considered to have RVR if serum HCV RNA level at 2 or 4

    weeks of treatment was below the cut off value of the referring local

    laboratory of each participating site.

    Measured: Evaluated at 2 and 4 weeks of treatment

  5. Number of Peripheral Blood Mononuclear Cells (PBMCs)

    Cellular Differentiation Cluster Antigen 8-Positive (CD8+) PBMCs were measured at randomization, Treatment Weeks 2, 4, 8, and 12.

    Measured: Treatment Weeks 2, 4, 8, and 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pegylated interferon alfa-2b and Ribavirin in people with 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 5 inclusion and 11 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 5 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 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 31 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 With Sustained Response (SR) at the End of the 6-month Follow-up Period (time frame: Evaluated at the end of 6 months). 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 NCT00686517, 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 5 Apr 2017.
