Genotypic resistance was assessed for all participants at screening and was evaluated for protease inhibitors (PIs), Nucleotide reverse transcriptase inhibitors (NRTIs), and non-NRTIs (NNRTIs) using Monogram GenoSeq and/or PhenoSenseGT assays.
This was then repeated for all participants with HIV-1 viral load more than 500 copies/mL either at treatment failure or at early termination, up to Week 96.

Ramy czasowe: Week 96 or Time of treatment failure
|
Phenotypic resistance was assessed for all participants at screening and was evaluated for PIs, NRTIs, and NNRTIs using Monogram GenoSeq and/or PhenoSenseGT assays.
This was then repeated for all participants with HIV-1 viral load more than 500 copies/mL either at treatment failure or at early termination, up to Week 96.

Number of Participants With HIV-1 RNA Tropism Status Using Trofile Assay
Ramy czasowe: Baseline to Week 96 or Time of treatment Failure

Viral tropism was determined using the trofile assay with enhanced sensitivity for participants with HIV-1 RNA greater than equal to 1000 copies/mL.
The enhanced trofile assay had the sensitivity to detect 100 percent of spiked samples when C-X-C chemokine receptor type 4 {CXCR4} [X4]-using HIV-1 RNA represented 0.3 percent of the total viral population.
