| Secondary | Change From Baseline in the Percentage of Total Lymphocytes (TLs) That Are CD4+ Cells at Weeks 2, 12, 24, and 48 | Blood samples of participants were collected for the measurement of the percentage of total lymphocytes that are CD4+ cells.

Change from Baseline in percentage was calculated as the value at Weeks 2, 12, 24, and 48 minus the value at Baseline. | ITT-E Population. Only those participants contributing data at the indicated time points were analyzed. The number of participants analyzed represents the sum of the PI-naïve (received <1 week's treatment with a PI) and -experienced (received >1 week prior PI therapy with no more than 3 PIs before trial enrollment) participants. | Posted | | Median | Inter-Quartile Range | Percentage of TLs that are CD4+ cells | | Baseline and Week 2, 12, 24, 48 | | | | ID | Title | Description |

| Secondary | Number of Confirmed Virologic Failure Participants (Par.) With Treatment-emergent HIV Genotypic Resistance in Reverse Transcriptase and Protease | A blood sample was drawn for par. failing to respond to therapy, and the mutations present in the virus were identified. For each par., the mutations found at the time of failure were compared with any mutations found in the blood sample at baseline. New International AIDS Society-USA defined resistance mutations that developed at the time of failure were tabulated by drug class. VF, virologic failure; NRTI, nucleoside reverse transcriptase inhibitor; NNRTI, non-nucleoside reverse transcriptase inhibitor; PI, protease inhibitor. Par. are grouped by study arm and prior therapy experience. | VF: par. with failure to achieve plasma HIV-RNA <400 copies/mL by Week 24; or confirmed HIV-RNA rebound to >=400 copies/mL any time after achieving plasma HIV-RNA <400 copies/mL and had evaluable viral isolate genotypic and/or phenotypic data.

Since the Week 48 Analysis With Treatment-emergent HIV Genotypic Resistance in Reverse Transcriptase and Protease | A blood sample was drawn for par. remaining in the study after Week 48 and failing to respond to therapy, and the mutations present in the virus were identified.

| Secondary | Number of Confirmed Virologic Failure Participants (Par.) With Treatment-emergent Reductions in Drug Susceptibility (DS) | A blood sample was drawn for par. failing to respond to therapy, and changes in DS for HIV isolated from the par. for each drug used in the study were assessed. The changes in DS detected by phenotypic assay in virus from the sample collected at the time of failure was compared with DS in the virus from the blood sample at baseline. Par. are grouped by study arm and prior therapy experience. DS is the state of HIV being susceptible to the antiretroviral agent (the virus can be inhibited by the drug). Reduced DS (i.e., HIV is resistant to the antiretroviral agent) can lead to treatment failure. | VF: par. with failure to achieve plasma HIV-RNA <400 copies/mL by Week 24; or confirmed HIV-RNA rebound to >=400 copies/mL any time after achieving plasma HIV-RNA <400 copies/mL and had evaluable viral isolate genotypic and/or phenotypic data.
