Study Endpoints
Primary Endpoints
Number of Participants With Plasma HIV-1 Ribonucleic Acid (RNA) <50 Copies Per Milliliter (c/mL) at Week 24 Using the Snapshot Algorithm
Week 24

The Food and Drug Administration (FDA) snapshot (Missing, Switch or Discontinuation = Failure) algorithm is intended to be primarily a virologic assessment of the endpoint, and as such follows a "virology first" hierarchy. Virologic Success (e.g., \<50 c/mL) or virologic failure within an analysis window is typically determined by the last available HIV-1 RNA measurement in that window and in the treatment phase of interest (e.g., Week 24 snapshot outcomes of the early switch phase will not use HIV-1 RNA data from the late switch phase, even if such data is within the Week 24 analysis window). A virologic failure occurs when a participant changes to their ART regimen (e.g., addition of other ARTs to the study-specified regimens, or switches in components of the current ART regimen).
