- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 69 Years
- Healthy Volunteers: f

Study Arms:
- TDF-TDF (Type: EXPERIMENTAL): TDF plus ADV placebo (double-blind period), followed by TDF (open-label period). Participants may add FTC (as part of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) FDC tablet) to their treatment regimen in the open-label period.
- ADV-TDF (Type: ACTIVE_COMPARATOR): ADV plus TDF placebo (double-blind period), followed by TDF (open-label period). Participants may add FTC (as part of FTC/TDF FDC tablet) to their treatment regimen in the open-label period.

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