Study Endpoints

Primary Endpoints

Percentage of Participants With Less Than 50 Copies Per Milliliter (Copies/mL) of Human Immunodeficiency Virus Type 1 Ribonucleic Acid (HIV-1 RNA) at Week 48
Week 48

Plasma HIV-1 RNA level was determined by validated Roche Amplicor HIV-1 Monitor standard assay.

Change From Baseline in Human Immunodeficiency Virus-1 (HIV-1) Viral Load at Day 8
Baseline, Day 8

Change from baseline in log 10-transformed plasma viral load(Human Immunodeficiency Virus-1 Ribonucleic Acid\[HIV-1 RNA\]) levels(log10 copies/milliliter\[copies/mL\])reported.Viral load determined using reverse transcriptase-polymerase chain reaction(RT-PCR) assay with standard lower limit of detection(LLOD) 400 copies/mL.For samples with reading less than (\<)400 copies/mL,assay repeated using ultra sensitive method with LLOD of 50 copies/mL.Values below limit of quantification(LOQ) 50 copies/mL set to 50 copies/mL.Baseline was mean of three pre-dose values taken at screening,randomization,Day 1.
