This randomized, open-label, crossover study will evaluate the relative bioavailability of ritonavir-boosted danoprevir fixed dose combination tablets (FDC) as compared to ad hoc combination of reference tablets of danoprevir and ritonavir in healthy volunteers. Subjects will be randomized to 1 of 6 treatment sequences to receive single oral doses of either an FDC of danoprevir and ritonavir or danoprevir and ritonavir as separate tablets. In a crossover design, subjects will participate in 3 study periods with at least a 7-day washout between periods. In Part 2, single dose administration of film-coated FDCs will be compared to reference tablets.

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Male and female volunteers, 18 to 55 years of age
  • Body weight >/= 50.0 kg
  • Body mass index (BMI) 18.0 - 32.0 kg/m2
  • Healthy non-smoking subjects. Healthy status will be defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history and a complete physical examination
  • Medical history without major, recent, or ongoing pathology
  • Females of childbearing potential and males and their female partners of childbearing potential must agree to use 2 forms of contraception, 1 of which must be a barrier method, during the study and for 90 days after the last drug administration

Exclusion Criteria:

  • Pregnant or lactating women or males with female partners who are pregnant or lactating
  • Any history of clinically significant cardiovascular or cerebrovascular disease, hypertension, and/or infections
  • Positive result for drugs of abuse at screening or prior to admission to the clinical site during any study period
  • Positive for hepatitis B, hepatitis C or HIV infection
  • Current smokers or subjects who have discontinued smoking less than 6 months prior to first dose of study medication
  • Use of hormonal contraceptives (e.g. birth control pills, patches, injectable, implantable devices) within 30 days before the first dose of study medication
  • Use of an investigational drug or device within 30 days of the first dose of study medication (6 months for biologic therapies) or 5 half-lives of the investigational drug, whichever is longer
  • History of drug-related allergic reactions or hepatotoxicity
  • History (within 3 months of screening) of alcohol consumption exceeding 2 standard drinks per day on average
