Primary

MeasureTime frameDescription
Percentage of Participants With Human Immunodeficiency Virus (HIV)-1 Ribonucleic Acid (RNA) Less Than (<) 50 Copies Per Milliliter (Copies/mL) (Virologic Response) at Week 48 Defined by Food and Drug Administration (FDA) Snapshot ApproachWeek 48Percentage of participants with a HIV-1 RNA \< 50 copies per mL were assessed using FDA snapshot approach which defines a participant's virologic response status using only the viral load at the predefined time point within a window of time, along with study drug discontinuation status. If HIV RNA level is \< 50 copies per mL at Week 48, it is considered as virologic success as per the snapshot approach.

Secondary

MeasureTime frameDescription
