Brief Summary:
The aim of the study is to see if apricitabine or tipranavir affect the levels of each other in the blood (pharmacokinetic interaction) when they are dosed together.

Condition or disease Intervention/treatment Phase
HIV Infection Drug: apricitabine Phase 1

Detailed Description:
Apricitabine is a new NRTI in development for treatment of drug resistant HIV. Tipranavir is a recently licensed protease inhibitor for treatment of drug resistant HIV. Tipranavir affects the plasma concentration of some other drugs when they are used together with tipranavir. This study will examine whether the pharmacokinetics of apricitabine are changed when it is dosed together with tipranavir compared to apricitabine alone. Also, the pharmacokinetics of tipranavir will be examined at steady state when it is dosed alone and when it is dosed together with apricitabine. Information on the safety and tolerability of the two drugs when dosed together will also be obtained.

Primary Outcome Measures :
  1. To compare the single dose pharmacokinetics of apricitabine when administered alone and in the presence of steady state concentrations of tipranavir 500 mg administered twice daily in combination with ritonavir 200 mg twice daily. [ Time Frame: day 1 and day 10 ]

Secondary Outcome Measures :
  1. To compare the steady state pharmacokinetics of tipranavir 500 mg administered twice daily with ritonavir 200mg in the presence and absence of apricitabine. [ Time Frame: day 9 and day 10 ]
  2. To evaluate the safety and tolerability of apricitabine administered in combination with tipranavir and ritonavir. [ Time Frame: day 10 ]
