Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Plasma HIV-1 RNA <40 c/mL at Week 24-Stage 2Week 24

Blood samples were collected for quantitative analysis of plasma HIV-1 RNA. Percentage of participants with plasma HIV-1 RNA \<40 c/mL at Week 24 was assessed using the Food and Drug Administration (FDA) snapshot algorithm which used the last on-treatment plasma HIV-1 RNA measurement, within an FDA-specified visit window (18 to 30 weeks), to determine response.
