  Purpose

This single-arm, open-label, non-randomized study will evaluate the effect of da noprevir/ritonavir on the pharmacokinetics of escitalopram and S-demethylcitalop ram in healthy volunteers. Healthy volunteers will receive oral doses of danopre vir/ritonavir and escitalopram. The anticipated time of the study is 6 weeks.

Primary Outcome Measures:
  • Change in area under the plasma concentration time curve (AUC) of escitalopram [ Time Frame: Approximately 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety: Incidence of adverse events [ Time Frame: Approximately 6 weeks ] [ Designated as safety issue: No ]
  • Effect on pharmacokinetics of major escitalopram metabolite: change in AUC of S-demethylcitalopram [ Time Frame: Approximately 4 weeks ] [ Designated as safety issue: No ]
  • Effect of co-administration of escitalopram on danoprevir/ritonavir steady-state pharmacokinetics: change in AUC of danoprevir/ritonavir [ Time Frame: Approximately 4 weeks ] [ Designated as safety issue: No ]
