About this study

Official title: A Study to Evaluate Safety, Tolerability, Pharmacokinetics and Antiviral Activity of Ritonavir-Boosted DANOPREVIR and RO5024048 in Different Combinations in Null Responder or Treatment Naïve Patients With Chronic Hepatitis C and Compensated Cirrhosis

This open-label, parallel cohort study will evaluate the safety, pharmacokinetics and antiviral activity of ritonavir-boosted danoprevir in combination with Pegasys (peginterferon alfa-2a) and ribavirin in treatment-naïve patients, and with RO5024048 added to the combination treatment in prior null responder patients with chronic hepatitis C genotype 1 or 4 and compensated cirrhosis. All patients will receive danoprevir 100 mg orally twice daily (bid) , ritonavir 100 mg orally bid, Pegasys 180 mcg subcutaneously weekly and ribavirin 1000-1200 mg/kg/day orally. Prior non-responders will receive RO5024048 1000 mg orally bid additionally. Anticipated time on study treatment is 24 weeks.

Being tested
RO5024048, danoprevir, peginterferon alfa-2a [Pegasys], ribavirin, ritonavir

What is being measured

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

  1. Safety: Incidence of adverse events

    Measured: 48 weeks

  2. Pharmacokinetics (PK): Area under the concentration-time curve (AUC)

    Measured: Intensive PK sample collection during initial 2 week dosing period, followed by routine sampling during treatment up to Week 24

  3. Antiviral activity: Hepatitis C virus (HCV) RNA levels assessed by Roche COBAS Taqman HCV Test

    Measured: 48 weeks

Secondary outcomes (2)
  1. Emergence of viral resistance: HCV RNA gene sequence variations

    Measured: From baseline to Week 48

  2. Virologic response: HCV RNA levels

    Measured: approximately 1 year

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 at 27 sites in 7 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 6 inclusion and 4 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 1 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 27 sites in United States, Poland, Australia, Canada, New Zealand and 2 more countries. 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 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Safety: Incidence of adverse events (time frame: 48 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?
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 1 Aug 2016.
