Estimated Enrollment: 100
Detailed Description:
Patients receive indinavir bid plus ritonavir bid, plus 2 NRTIs bid (2 new NRTIs or 1 new NRTI and 1 NRTI without evidence of resistance). CD4 cell counts and plasma viral RNA are measured every 4 weeks for the duration of the study. Physical examination and laboratory tests of blood and urine are performed every 4 weeks for the duration of the study. Chest x-ray and 12-lead ECG are done prestudy.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria

Patients may be eligible for this study if they:

  • Are HIV-positive.
  • Are 18 years of age or older.
  • Have a CD4 cell count of at least 50 cells/mm3.
  • Have a viral load (level of HIV in the blood) of at least 400 copies/ml but no more than 20,000 copies/ml.
  • Have had an initial response to protease inhibitor therapy with a viral load of less than 400 copies/ml in two consecutive tests at least 1 week apart.
  • Have been on anti-HIV (antiretroviral) treatment including indinavir or nelfinavir for at least 16 weeks.
  • Have had virologic failure (two consecutive viral loads that were greater than or equal to 400 copies/ml and less than or equal to 20,000 copies/ml at least 1 week apart) that is not due to another infection, vaccination, or a temporary stop in treatment.
  • Are naive to at least one of the selected NRTIs.
