Study Start Date: February 2001
Study Completion Date: September 2003
Primary Completion Date: September 2003 (Final data collection date for primary outcome measure)
Detailed Description:
The study is designed to determine the metabolic changes, antiviral activity, safety, and tolerability of atazanavir as compared to LPV/RTV, each in combination with 2 nucleosides, over the initial 24 weeks, with a final analysis at 48 weeks.

Ages Eligible for Study:   16 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria

  • Have 2 CD4 cell counts of 50 or more cells/mm3 at least 96 hours apart and within 4 weeks before randomization.
  • Are at least 16 years old.
  • Have a documented virologic response to at least 1 HAART regimen.
  • Have phenotypic sensitivity to at least 2 of the following: ddl, d4T, ZDV, 3TC, ABC.
  • Have phenotypic sensitivity to atazanavir and LPV/RTV.
  • Use effective barrier methods of birth control.
  • Will be available for 48 weeks.

Exclusion Criteria

Patients will not be eligible for this study if they:

  • Have taken 2 or more PIs and had virologic failure.
  • Have taken atazanavir or LPV/RTV.
  • Have an HIV-related infection (within 30 days) or any medical condition requiring treatment at the time of enrollment.
  • Have had acute hepatitis in the 30 days prior to study entry.

  • Have cardiomyopathy or symptoms of other heart disease.
  • Cannot take medicine by mouth.
  • Have any other condition that would interfere with the study.
  • Have pancreatitis, if choosing ddI as part of NRTI pair.
  • Have bilateral peripheral neuropathy at time of screening, if choosing ddI or or d4T as part of the NRTI pair.
