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.

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
時間枠: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.
