Study Arms:
- TAF 25 mg (Type: EXPERIMENTAL): TAF + TDF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).
- TDF 300 mg (Type: ACTIVE_COMPARATOR): TDF + TAF placebo for 96 weeks (per amendment 1 \& 2) or 144 weeks (per amendment 3).
- Open-label TAF (Type: EXPERIMENTAL): All participants who complete the double-blind period (96 weeks or 144 weeks) will be eligible to receive open-label TAF until Week 384 of the study.~After the end of study treatment, participants can either switch to commercially available anti-HBV treatments in their country or will be followed every 4 weeks, for up to 24 weeks off treatment (treatment-free follow-up (TFFU)) for safety assessment.

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