Study Details
Study Description
Brief Summary
This is a 48 week study that is intended for HIV Infected persons whose first treatment regimen was with a nonnucleoside reverse transcriptase inhibitor (NNRTI) and who are now failing that regimen. They must be currently on their failing regimen to be eligible.

Outcome Measures
Primary Outcome Measures
- The primary objective was to determine whether the addition of capravirine to a regimen of VIRACEPT and 2 new nucleoside reverse transcriptase inhibitors would provide a higher virologic response rate over 48 weeks []
- when compared to a 3-drug regimen without capravirine in patients who had experienced virologic failure while on a nonnucleoside reverse transcriptase inhibitor regimen. []
Secondary Outcome Measures
- The safety and tolerability of 2 doses of capravirine. []
- The difference between 2 doses of capravirine in terms of tolerability, efficacy, and pharmacokinetics []
- The relationship of HIV resistance (genotype and phenotype) to virologic response. []
- The immunologic response as determined by CD4 and CD8 absolute lymphocyte counts []
- The population pharmacokinetics of capravirine and VIRACEPT []
- The pharmacokinetics of potential drug-drug interactions. []
