Completed · Phase 1

Conditions studied: Healthy Volunteer

In brief

This single-dose, randomized, open-label, 2-sequence, 3-period study will evaluate the effect of cyclosporine on the pharmacokinetics of ritonavir-boosted danoprevir (DNV/r) in healthy volunteers. Subjects will be randomized to one of two treatment sequences to receive a single oral dose of DNV/r or cyclosporine. In treatment period 3, subjects will receive a single oral dose of DNV/r plus cyclosporine. Anticipated time on study is 33 days.
