Conditions: HIV Infections
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 33
Healthy volunteers: no

Brief summary:
The primary purpose of this study is to:

1. Demonstrate the safety and efficacy of tipranavir/ritonavir (TPV/r) among a racially diverse HIV+ population (males and females) who are three-class (nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), and protease inhibitor (PI)) experienced with documented resistance to more than one PI.
2. Determine pharmacokinetic data in this racially and gender diverse population.
3. Determine the potential utility of using therapeutic drug monitoring (TDM) in improving efficacy outcomes.

Detailed description:

Arms:
arm 1: Standard of Care (SOC) Arm = Tipranavir/ritonavir (TPV/r) capsules taken orally at a dose of 500 mg/200 mg twice a day (BID) plus optimized background regimen (OBR). No TPV/r dose changes were permitted. arm 2: Therapeutic Drug Monitoring (TDM) Arm = Patients began by receiving standard of care (SOC) tipranavir/ritonavir (TPV/r) capsules orally at a dose of 500 mg/200 mg twice a day (BID) plus optimized background regimen (OBR) followed, if needed, by TPV or ritonavir (RTV) dose adjustments at Week 4, 6, 10, 14, 18, 22, 26 and 30 based on viral response, phenotypic inhibitory quotient (IQ), and TPV trough concentrations.

Interventions: intervention 1: tipranavir intervention 2: ritonavir intervention 3: Optimized Background Regimen (OBR)
Intervention descriptions: intervention 1: None intervention 2: None intervention 3: Patients received between two and four active anti-retroviral medications based on resistance testing results, as background treatment, and remained on these for the duration of the trial.
