Summary
Brief summary
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.
