At Week 96, participants in the United States (US) who wished to participate in the open-label (OL) rollover extension either discontinued E/C/F/TAF FDC or continued to take E/C/F/TAF FDC for up to 114 weeks. At Week 96 or the end of E/C/F/TAF visit (whichever occurred last), participants were given the option to receive open-label (OL) bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) (Biktarvy®, BVY) (50/200/25 mg) FDC tablet once daily without regard to food for up to 52 weeks.
