The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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.
Effect of coadministration of darunavir (DRV), danoprevir (DNV) and ritonavir (RTV) on DRV/DNV/RTV pharmacokinetics: Area under the concentration-time curve (AUC) [ Time Frame: approximately 2 months ]
Secondary Outcome Measures :
Safety: Incidence of adverse events [ Time Frame: approximately 2 months ]
