简要总结
The purpose of this study is to learn how well atazanavir (ATV) works in combination with ritonavir (RTV) or saquinavir (SQV) with tenofovir (TDF) and a nucleoside to reduce the viral load of treatment experienced subjects with human immunodeficiency virus (HIV). There is a comparison arm with lopinavir (LPV)/RTV and TDF and a nucleoside.

入选标准
- •Virologic failure to 2 or more highly active antiretroviral therapy (HAART) regimens that, in total, have included at least one drug from all approved classes protease inhibitors, non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors (PI, NNRTI, NRTI):
- •Currently on a failing HAART regimen with 2 qualifying plasma viral load measurements (hospital/clinic value within 4 weeks of screening with viral load equivalent to =>1,000 c/mL on the Roche Amplicor[TM] and central lab measurements of =>1,000 c/mL (Roche Amplicor[TM]) within 4 weeks of randomization
- •Cluster of Differentiation 4 (CD4) cell count =>50 cells/mm3 obtained within 4 weeks prior to randomization
- •=>16 years of age (or minimum age as determined by local regulations or as legal requirements dictate);
- •History of prior virologic response to at least one HAART regimen, defined as a 1.0 log10 decline or a decline in viral load to <400 c/mL by Roche Amplicor or <500 c/mL by Chiron Quantiplex branched DNA (bDNA) assay
- •Both females of child bearing potential and males must utilize effective barrier contraception to reduce transmission of sexually transmitted disease, including human immunodeficiency virus (HIV). Other contraception in addition to barrier methods is permitted; interaction between atazanavir and oral contraceptives has not been studied.
- •Subjects must be able to provide written informed consent;
- •Subjects should be available for follow-up for a period of at least 48 weeks
- •Baseline laboratory values measured within 2 weeks prior to initiating study drugs as follows:
- •serum creatine <1.5 times the upper limit of normal (ULN)

排除标准
- •Prior use (=>3 days) of atazanavir, TVF or LPV/RTV; if history of SQV, then must be phenotypically sensitive

- •Active alcohol or substance use sufficient, in the Investigator's opinion, to prevent adequate compliance with study therapy or to increase the risk of developing pancreatitis or chemical hepatitis

- •Inability to tolerate oral medications
- •Any other clinical conditions or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for study or unable to comply with the dosing requirements.
