Study Arms:
- E/C/F/TAF (Double-Blind) (Type: EXPERIMENTAL): E/C/F/TAF plus E/C/F/TDF placebo for 144 weeks~After 144 weeks, participants will continue to take their blinded study drug until treatment assignments have been unblinded.
- E/C/F/TDF (Double-Blind) (Type: ACTIVE_COMPARATOR): 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.
- Open-Label E/C/F/TAF (Type: EXPERIMENTAL): 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.

Based on this trial design, predict the completion outcome and termination type (if applicable).
