ANNAPURNA: A Study of The Combination of RO5466731, RO5190591, Ritonavir and Copegus (Ribavirin) With or Without RO5024048 in Patients With Chronic Hepatitis C Who Are Either Treatment-Naïve or Have Previously Experienced a Null Response to Interferon-Based Treatment

This randomized, open-label, multicenter study will evaluate the safety , efficacy and tolerability of the combination treatment RO5466731, RO5190591, ritonavir and Copegus (ribavirin) with or without RO5024048 in patients with chronic hepatitis C genotype 1. In Part 1, treatment-naïve patients will be randomized to receive treatment with RO5466731, RO5190591 plus ritonavir, and Copegus, with or without RO5024048. In Part 2, further treatment-naïve patients will receive a successful regimen from Part 1, or a reduced intensity regimen, and patients who have previously experienced null response to interferon-based treatment will be added to the study.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult patients, >/= 18 years of age
  • Chronic hepatitis C genotype 1 of >/= 6 months duration at screening
  • Part 1 and Part 2: Naïve to treatment with interferon (pegylated or non-pegylated). Patients who have participated in studies investigating a direct-acting antiviral agent with or without interferon are excluded
  • Part 2: Treatment experienced patients having a previous null response to treatment with interferon containing regimen
  • Liver biopsy or non-invasive (e.g. Fibroscan) evaluation in the past 24 calendar months showing absence of cirrhosis or incomplete/transition to cirrhosis
  • Body mass index (BMI) 18 to 35 kg/m2 inclusive and body weight >/= 45 kg

Exclusion criteria

  • Pregnant or lactating women or males with female partners who are pregnant or lactating
  • Decompensated liver disease or impaired liver function (as defined by protocol)
  • Cirrhosis or incomplete/transition to cirrhosis
  • Non- hepatitis C chronic liver disease
  • Positive for hepatitis B or HIV infection
  • History of pre-existing renal disease
  • History of severe cardiac disease
  • History of neoplastic disease within the last 5 years, except for localized or in situ carcinoma of the skin
  • History of drug abuse within the last year; history of cannabinoid use is not excluded
  • Evidence of alcohol abuse within 1 year of screening and consumption of more than 2 units of alcohol per day
  • Medical condition that requires use of systemic corticosteroids
  • Received warfarin or other anticoagulants during the 21 days immediately prior to screening or is expected to require warfarin or other anticoagulants during the study
  • Anticipated use or need for significant medical treatment during the study or use of concomitant medications or nutrients that are excluded by protocol (e.g. drugs that are contraindicated with ritonavir, hormonal methods of contraception)
