About this study

This randomized, double blind, phase II study will evaluate the efficacy and safety of two doses of RO5024048 in combination with ritonavir-boosted danoprevir and Pegasys (peginterferon alpha-2a) and Copegus (ribavirin) in patients who failed a prior protease inhibitor containing regimen with or without pegylated interferon. Patients will be randomized to receive either a 2-week lead-in of RO5024048 (1500 mg or 1000 mg orally twice daily) in combination with Pegasys (180 mcg subcutaneously weekly) and Copegus (1000 mg or 1200 mg orally daily) followed by 24 weeks of therapy with RO5024048 in combination with danoprevir (100 mg orally twice daily) plus ritonavir (100 mg orally twice daily) and Pegasys and Copegus (QUAD therapy), or 24 weeks of therapy with RO5024048 in combination with danoprevir plus ritonavir and Pegasys and Copegus (QUAD therapy). Anticipated time on study treatment is 24 or 26 weeks, with a treatment-free follow-up of 24 weeks.

What is being measured

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

  1. Sustained virologic response (defined as unquantifiable serum HCV RNA) 12 weeks after treatment (SVR-12)

    Measured: approximately 2 years

Secondary outcomes (7)
  1. Sustained virologic response 4 weeks after treatment (SVR-4)

    Measured: approximately 2 years

  2. Sustained virologic response 24 weeks after treatment (SVR-24)

    Measured: approximately 2 years

  3. Change in serum HCV RNA levels

    Measured: from baseline to Week 12

  4. Virologic response over time

    Measured: from baseline to 24 weeks after treatment

  5. Correlation between trough concentrations of RO4995855 and virologic response

    Measured: approximately 2 years

  6. Incidence of direct-acting antiviral (DAA) resistance, including re-emergence of protease inhibitor resistant virus

    Measured: approximately 2 years

  7. Safety: Incidence of adverse events

    Measured: approximately 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RO5024048, danoprevir and peginterferon alfa-2a [Pegasys] in people with Hepatitis C, Chronic, run by Hoffmann-La Roche.

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 6 inclusion and 15 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 2 Nov 2016. 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 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?

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?

Sustained virologic response (defined as unquantifiable serum HCV RNA) 12 weeks after treatment (SVR-12) (time frame: approximately 2 years). 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 2 Nov 2016; AzTrials last refreshed its copy on 7 Nov 2026.
