NCT01483742
First received: November 30, 2011

  Purpose

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.

Primary Outcome Measures:
  • Safety: Incidence of adverse events [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]
  • Pharmacokinetics: Area under the concentration-time curve (AUC) [ Time Frame: Intensive PK sample collection during initial 2 week dosing period, followed by routine sampling during treatment up to Week 24 ] [ Designated as safety issue: No ]
  • Antiviral activity: HCV RNA levels assessed by Roche COBAS Taqman HCV Test [ Time Frame: 48 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Emergence of viral resistance: HCV RNA gene sequence variations [ Time Frame: From baseline to Week 48 ] [ Designated as safety issue: No ]
  • Virologic response: HCV RNA levels [ Time Frame: approximately 1 year ] [ Designated as safety issue: No ]
