Dataset from A Prospective, Randomized, Open-labelled, Multi-centre Trial Comparing the Safety and Efficacy of Ritonavir-boosted Aptivus (Tipranavir, TPV/r) to That of Prezista® (Darunavir, DRV/r) in Three-class (NRTI, NNRTI, and PI) Treatment-experienced Patients With Resistance to More Than One PI. POTENT: PrOspecTive EvaluatioN of Tipranavir vs. Darunavir in Treatment Experienced Patients

The objective of this study is to compare the efficacy and safety of Tipranavir/ritonavir (TPV/r, 500mg/200mg twice daily) to the safety and efficacy of Darunavir/ritonavir (DRV/r 600 mg /100 mg twice daily) in combination with investigator selected optimised background regimens in patients who are three-class (Nucleoside reverse transcriptase inhibitors (NRTI), Nonnucleoside reverse transcriptase inhibitors (NNRTI), and Protease inhibitor (PI)) treatment-experienced (a minimum of 3-months duration for each class) with resistance to more than one PI on the screening virtual phenotype resistance testing.
