This randomized, double-blind, placebo controlled, 3 part study will assess the safety, tolerability and pharmacokinetics of RO5303253 in healthy volunteers and patients with chronic hepatitis C genotype 1. In Part A, cohorts of healthy volunteers will be randomized to receive single ascending doses of RO5303253 or placebo. In Part 2, healthy volunteers will receive a single dose of RO5303253 or placebo in a cross-over design (with a washout period of at least 7 days) to assess food effects on pharmacokinetics. In Part 3, patients with chronic hepatitis C will be randomized ro receive either RO5303253 or placebo for 5 days.

Primary Outcome Measures:
  • Safety and tolerability: Adverse events, laboratory parameters, ECG, blood pressure [ Time Frame: approximately 6 months ] [ Designated as safety issue: No ]
  • Pharmacokinetics: Plasma and urine concentrations of RO5303253 and its main metabolite RO1080713 [ Time Frame: approximately 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Effect of food intake on pharmacokinetics in healthy volunteers [ Time Frame: Days 1-4 ] [ Designated as safety issue: No ]
  • Pharmacodynamics (viral responses) and drug resistance profiling in chronic hepatitis C patients [ Time Frame: From baseline to Day 15 ] [ Designated as safety issue: No ]
