Study Endpoints
Primary Endpoints
Percentage of Participants Achieving <40 Copies/mL Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Week 48
Week 48

From blood samples collected at week 48, HIV-1 RNA levels were determined by the Abbott RealTime HIV-1 Assay, which has a limit of reliable quantification (LoQ) of 40 copies/mL. The NC=F approach as defined by FDA "snapshot" approach was used as the primary approach to analysis where all missing data were treated as failures regardless of the reason.

Secondary Endpoints
Percentage of Participants Achieving <40 Copies/mL Human Immunodeficiency Virus-1 (HIV-1) Ribonucleic Acid (RNA) at Week 96
