SECONDARY outcome

Timeframe: Baseline up to Week 24, 48, 96

Population: ITT population. Participant discontinued before a visit of interest: value imputed as zero; not discontinued but observation was missing: value calculated to the last non-missing timepoint; not discontinued and missing values between baseline and visit: ignore missing values; missing baseline or no HIV-1 RNA level assessment: value imputed as zero.

TAD was calculated as area under the curve of HIV-1 RNA levels (log10 copies/mL) from baseline to the time point of interest divided by time period in weeks minus baseline HIV-1 RNA level (log10 copies/mL). Baseline value was calculated as the average of all the measurements collected prior to and including Day 1 pre-dose.

SECONDARY outcome

Timeframe: Week 24, 48, 96

Population: ITT population included all randomized participants who received at least 1 dose of study medication. Missing value was imputed per the TLOVR algorithm.

TLOVR50 response is compliment to TLOVR50 failure. TLOVR50 failure based on observed HIV-1 RNA levels and failure events (death; permanent discontinuation of drug; lost to follow-up; met treatment failure \[TF\] criteria). TF: an increase to at least 3 times baseline plasma HIV-1 RNA level at Week 2 or thereafter; failure to achieve HIV-1 RNA level \<50 copies/mL at Week 24; starting at Week 2, an increase in HIV-1 RNA level to detectable levels (\>50 copies/mL). TF criteria's defined above were confirmed by second measurement at least 14 days after first. In 'TLOVR50', '50' denotes the lower limit of quantification (LLOQ) of assay (which is 50 copies/mL). Baseline value was calculated as the average of all the measurements collected prior to and including Day 1 pre-dose.

Phenotypic resistance and genotypic resistance was assessed for all participants at Day 1 predose, and was evaluated for nucleotide reverse transcriptase inhibitors (NRTIs), and non-NRTIs (NNRTIs) resistance-associated mutations at time of treatment failure using Monogram GenoSeq and/or PhenoSenseGT assays. This was then repeated for all participants with HIV-1 viral load more than 500 copies/mL at treatment failure, up to Week 96.
