Outcome Measures

Primary Outcome Measures

  1. 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 []

  2. 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

  1. The safety and tolerability of 2 doses of capravirine. []

  2. The difference between 2 doses of capravirine in terms of tolerability, efficacy, and pharmacokinetics []

  3. The relationship of HIV resistance (genotype and phenotype) to virologic response. []

  4. The immunologic response as determined by CD4 and CD8 absolute lymphocyte counts []

  5. The population pharmacokinetics of capravirine and VIRACEPT []

  6. The pharmacokinetics of potential drug-drug interactions. []
