Dataset from 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 Patients.

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).
