Brief Summary:
The purpose of this study is to assess the virologic impact of switching treatment-experienced HIV-infected patients with virologic failure to a salvage regimen with or without a 12 week STI prior to the switch.
Hypothesis: A STI prior to starting a salvage regimen will result in an improved virologic response.
Hypothesis: A STI prior to starting a salvage regimen will result in an improved virologic response.
Detailed Description:
To prospectively determine the virologic impact of switching treatment-experienced HIV-infected patients with virologic failure to a salvage regimen with or without a 12 week STI prior to the switch.
Hypothesis: By withdrawing ARV drug pressure, resistant HIV virus will revert to wild-type. In treatment-experienced HIV patients who experience virologic failure, a STI prior to starting a salvage regimen will result in an improved virologic response and more prolonged vral suppression compared to immediate switching to a new regime.
Interventions:
Immediate Switch to Salvage Therapy: Patients randomized to the control arm will be switched immediately to a salvage regimen using the information from the treatment history and genotype results.
Structured Treatment Interruption: Patients randomized to the STI arm will have their present regimen stopped for 12 weeks and will have a genotype repeated in the 12th week. A salvage regimen will be started at week 12 using the information from the treatment history and baseline genotype results.
