PRIMARY outcome

Timeframe: Week 48

Population: Efficacy analyses were based on the Full Analysis Set population that included all participants who took at least one dose of study medication and had at least one postbaseline evaluation. The Treatment-Related Discontinuation = Failure approach was used as the primary method for handling missing HIV RNA values.

Numbers of participants with HIV RNA copies \<50 copies/mL were summarized by race for each time point.

SECONDARY outcome

Timeframe: Week 48

Population: Efficacy analyses were based on the Full Analysis Set population that included all participants who took at least one dose of study medication and had at least one postbaseline evaluation.

For participants with confirmed HIV RNA levels \<50 copies/mL on 2 consecutive visits, loss of virologic response is the occurrence of the first value \>50 copies/mL or loss to follow-up; participants who never achieved HIV RNA \<50 copies/mL on 2 consecutive visits are also considered as having loss of virologic response. Events are the numbers of participants with loss of virologic response versus the numbers of participants with no loss of virologic response (event free).
