SPRING: Safety, Efficacy, Pharmacokinetics of tipRanavi/r IN Race/Gender HIV+ Patients Randomized to Therapeutic Drug Monitoring or Standard of Care

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
