Brief Summary:

This is an open-label, randomized, parallel group pharmacokinetics trial of tipranavir/ritonavir (TPV/RTV), alone or in combination with RTV-boosted saquinavir (SQV), amprenavir (APV) or lopinavir (LPV), plus an optimized background regimen, in multiple antiretroviral (ARV) experienced HIV-1 patients.

The primary objective is to determine the safety and pharmacokinetics of:

TPV/RTV given with an optimized background regimen (OBR) and TPV/RTV given in combination with saquinavir, amprenavir, or Kaletra® and an optimized background regimen (OBR).

Primary Outcome Measures :
  1. Change of the 2nd Protease Inhibitor (PI) (APV, LPV. SQV) mean concentration (C12h) [ Time Frame: Day 14 to Day 28 ]
  2. Occurrence of adverse events; Proportion of patients with laboratory abnormalities; Proportion of patients with SAEs [ Time Frame: week 4 ]

Secondary Outcome Measures :
  1. Mean concentration (C12h) of TPV (TPV/r group); Mean concentration (C12h) of RTV (TPV/r group) [ Time Frame: Week 1 and 2 ]
  2. Mean concentration (C12h) of TPV (PI/TPV/r group); Mean concentration (C12h) of RTV (PI/TPV/r group) [ Time Frame: Week 3 and 4 ]
  3. Assessment of patient adherence [ Time Frame: Week 1 to 4 ]
  4. Area under the Curve (AUC(0-12h)) of the 2nd PI (APV, LPV. SQV); Maximum concentration (Cmax) of the 2nd PI (APV, LPV. SQV); Concentration (C12h) of the 2nd PI (APV, LPV. SQV) [ Time Frame: week 2 and 4 ]
  5. Change in AUC(0-12h) of TPV from week 2; Change in Cmax of TPV from week 2; Change in C12h of TPV from week 2 [ Time Frame: week 4 ]
  6. Change in AUC(0-12h) of RTV from week 2; Change in Cmax of RTV from week 2; Change in C12h of RTV from week 2 [ Time Frame: week 4 ]
  7. AUC(0-12h) of RTV; Cmax of RTV; C12h of RTV [ Time Frame: week 2 and 4 ]
  8. Change in viral load; Proportion of virologic responders [ Time Frame: week 2, 4, 8, 16 and 24 ]
