A Study of Drug-Drug Interaction Between Darunavir and Danoprevir Administered Together With Low-Dose Ritonavir in Healthy Volunteers

Phase 1

Completed

• Conditions: Healthy Volunteer
• Interventions: Drug: danoprevir; Drug: darunavir; Drug: ritonavir

• Registration Number: NCT01519336
• Lead Sponsor: Hoffmann-La Roche

Brief Summary

This randomized, open-label, multiple-dose, 2-period crossover study will evaluate potential drug-drug interactions between darunavir and danoprevir when administered together with low-dose ritonavir in healthy volunteers. In Period 1, subjects will be randomized to receive either darunavir or danoprevir together with low-dose ritonavir for 10 days. In Period 2, all subjects will receive darunavir plus danoprevir together with ritonavir for 10 days. Anticipated time on study treatment is 20 days.
