Healthy Volunteer
Conditions
Brief summary
This single dose, randomized, open-label, 6 sequence, 3-period, crossover study will evaluate the relative bioavailability of danoprevir and ritonavir in healthy volunteers. In Part 1, subjects will be randomized to receive single oral doses of one of three tablet formulations of danoprevir plus the reference ritonavir formulation, with an at least 7-day washout between periods. In Part 2, subjects will be randomized to receive single oral doses of one of three tablet formulations of ritonavir plus the reference formulation of danoprevir, with at least a 7-day washout betwen periods. The anticipated time on study is up to 30 days.
