NCT00053404

Brief Summary

Drug resistant HIV strains often develop in patients who have taken anti-HIV drugs for an extended time. However, these drug resistant HIV strains do not always cause an increase in the level of HIV in the blood. This study will explore why some patients with drug resistant virus continue to have low viral loads.

  • Documented pretherapy or off-therapy viral load of more than 10,000 copies/ml on at least 2 occasions or more than 20,000 copies/ml on at least 1 occasion
  • At least a 70% reduction in plasma HIV RNA levels from pretherapy baseline
  • Stable highly active antiretroviral therapy (HAART) regimen for at least 4 months prior to study entry
  • HIV viral load of 200 to 10,000 copies/ml for 3 months prior to study entry
  • CD4 count greater than 100 cells/mm3 and a nadir CD4 count less than 500 cells/mm3
  • Virologic failure as defined by DHHS guidelines on at least one HAART regimen prior to the study entry HAART regimen
