E/C/F/TDF plus E/C/F/TAF placebo for 144 weeks After 144 weeks, participants will continue to take their blinded study drug until treatment assignments have been unblinded.
After the unblinding visit, in countries where E/C/F/TAF is not commercially available, participants (except in UK) who complete 144 weeks of study will be given the option to receive open-label E/C/F/TAF and attend study visits every 12 weeks until it becomes commercially available, or until Gilead terminates the study in that country.
