This study was designed to test the efficacy, safety, tolerability and durability of the antiviral response between atazanavir (ATV) + ritonavir (/r) + abacavir/lamivudine(ABC/3TC) Fixed dose combination (FDC) each administered once daily (QD) for 36 weeks followed by randomization to either a simplification regimen of ATV or continuation of ATV +/r for an additional 48 weeks, each in combination with ABC/3TC in antiretroviral (ART)-naive, HIV-1 infected, HLA-B*5701 negative subjects. All subjects who complete the 84-week study will be eligible to enter the treatment extension phase and continue for an additional 60 weeks. The purpose of this extension is to obtain longer term treatment data in subjects who have completed the 84-week study.

Measure: Number of Participants Who Experienced Death and/or Disease Progression Time: From Baseline to Week 48Description: A blood sample was drawn for particiapants with confirmed VF >=400 c/mL. For each participant, the mutations found at the time of failure were compared with any mutations found in the blood sample at Baseline. New resistance-associated viral mutations defined by the International Acquired Immunodeficiency Syndrome Society-United States of America guidelines present at the time of failure were tabulated by drug class. NRTI, nucleoside reverse transcriptase inhibitor; NNRTI, non-nucleoside reverse transcriptase inhibitor; PI, protease inhibitor.
Measure: Number of Confirmed Virologic Failure (VF) Participants (PAR) With Treatment-emergent HIV Genotypic Resistance in Reverse Transcriptase and Protease From Baseline Through Week 24 Time: From Baseline to Week 24Description: A blood sample was drawn for particiapants with confirmed VF >=400 c/mL. For each participant, the mutations found at the time of failure were compared with any mutations found in the blood sample at Baseline. New resistance-associated viral mutations defined by the International Acquired Immunodeficiency Syndrome Society-United States of America guidelines present at the time of failure were tabulated by drug class. NRTI, nucleoside reverse transcriptase inhibitor; NNRTI, non-nucleoside reverse transcriptase inhibitor; PI, protease inhibitor.
Measure: Number of Confirmed Virologic Failure (VF) Participants (PAR) With Treatment-emergent HIV Genotypic Resistance in Reverse Transcriptase and Protease From Baseline Through Week 48 Time: From Baseline to Week 48Description: A blood sample was drawn for participants failing to respond to therapy, and changes in drug susceptibility for HIV isolated from the participants for each drug used in the study were assessed. For each participant, the changes in drug susceptibility detected by phenotypic assay in virus from the sample collected at the time of failure was compared with drug susceptibility in the virus from the blood sample at Baseline.
Measure: Number of Confirmed Virologic Failure Participants (PAR) From Baseline Through Week 24 With the Indicated Treatment-emergent Reductions in Susceptibility to Abacavir, Lamivudine, Tenofovir, Emtricitabine, Atazanavir, or Ritonavir Time: From Baseline to Week 24Description: A blood sample was drawn for participants failing to respond to therapy, and changes in drug susceptibility for HIV isolated from the participants for each drug used in the study were assessed. For each participant, the changes in drug susceptibility detected by phenotypic assay in virus from the sample collected at the time of failure was compared with drug susceptibility in the virus from the blood sample at Baseline.
Measure: Number of Confirmed Virologic Failure Participants (PAR) From Baseline Through Week 48 With the Indicated Treatment-emergent Reductions in Susceptibility to Abacavir, Lamivudine, Tenofovir, Emtricitabine, Atazanavir, or Ritonavir Time: From Baseline to Week 48Description: The National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 is a descriptive terminology that can be utilized for AE reporting. A grading (severity) scale is provided for each AE. Grade refers to the severity of the adverse event (AE). The CTCAE v3.0 displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1, mild AE; Grade 2, moderate AE; Grade 3, severe AE; Grade 4, life-threatening or disabling AE; Grade 5, death related to the AE.
Measure: Number of Participants With the Indicated Grade 2 to Grade 4 Adverse Events (AEs) Occurring at a Frequency of >=3% in Either Treatment Group Time: From Baseline to Week 24Description: The National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0 is a descriptive terminology that can be utilized for AE reporting.
