The objective of this study is to evaluate the drug-drug interaction potential between BI 201335 and concomitantly administered tenofovir which is used in treatment regimens for HIV infection and/or Hepatitis B infection. Results of this study will serve as a basis for guidance of dose adjustments or other precautionary measures when BI201335 and tenofovir are coadministered.

Masking: Open Label
Primary Purpose: Treatment
||Effect of Multiple Dosing With 240 mg BID BI 201335 on the Steady State Pharmacokinetics of 300mg QD Tenofovir and Effect of Multiple Dosing With 300mg QD Tenofovir on Steady State BI 201335 Pharmacokinetics in Healthy Male and Female Volunteers
Primary Outcome Measures:

- Comparison of steady-state pharmacokinetics of Cmax of tenofovir on Day 7 with Day 15 [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
- Comparison of steady-state pharmacokinetics of C24hr of tenofovir on Day 7 with Day 15 [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
- Comparison of steady-state pharmacokinetics of Cmax of BI 201335 on Day 15 and Day22 [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
- Comparison of steady-state pharmacokinetics of C12hr of BI 201335 on Day 15 and Day 22 [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Number of adverse events during the trial [ Time Frame: approximately 4 weeks ] [ Designated as safety issue: No ]
