This open-label, multiple dose, single sequence crossover study will evaluate the drug-drug interaction between danoprevir/low-dose ritonavir and raltegravir in healthy volunteers. Subjects will receive raltegravir on Days 1-4 and, after a washout period of 3 days, danoprevir and low-dose ritonavir on Days 8-21, in combination with raltegravir on Days 18-21.

Primary Outcome Measures:
  • Effect of steady-state ritonavir-boosted danoprevir on steady-state raltegravir pharmacokinetics: Area under the concentration-time curve (AUC) [ Time Frame: approximately 2 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Effect of steady-state raltegravir on danoprevir/ritonavir pharmacokinetics: Area under the concentration-time curve (AUC) [ Time Frame: Pre-dose Days 8. 14, 15, 16 and 20, pre-and up to 24 h post-dose Days 17 and 21 ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: approximately 2 months ] [ Designated as safety issue: No ]
