Brief Summary:
The investigators believe that boceprevir's drug concentrations will be reduced when administered in combination with etravirine. The investigators believe that etravirine's drug concentrations will be increased when administered in combination with boceprevir. Additionally, the investigators believe that boceprevir and etravirine are safe when administered alone or in combination.

Condition or disease Intervention/treatment Phase
Hepatitis C HIV Drug: boceprevir; etravirine Not Applicable

Detailed Description:
To investigate the potential for drug interactions between boceprevir and etravirine, participants will receive each drug alone and the drugs in combination for 11-14 days. The pharmacokinetics of boceprevir and etravirine when given in combination vs. alone will be compared.
