Individuals with cutaneous KS are eligible, but must not have received any systemic therapy for KS within 30 days of Part 1, Day 1 and must not be anticipated to require systemic therapy during the study.~* Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Part 1, Day 1~* Any other clinical condition or prior therapy that would make the individual unsuitable for the study or unable to comply with dosing requirements~* Participation in any other clinical trial (including observational trials) without prior approval from the sponsor is prohibited while participating in this trial~* Receiving ongoing therapy with any disallowed medications, including any drugs not to be used with elvitegravir, cobicistat, emtricitabine and tenofovir alafenamide or known allergies to the excipients of E/C/F/TAF STR~Note: Other protocol defined Inclusion/Exclusion criteria may apply.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Part 1 Sentinel Cohort (TAF) (Type: EXPERIMENTAL): TAF + their current failing ARV regimen for 10 days in Part 1
- Part 1 Randomized Cohort (TAF) (Type: EXPERIMENTAL): Following review of safety and efficacy data from the Sentinel Cohort, participants will be randomized to receive TAF + their current failing ARV regimen for 10 days in Part 1.
- Part 1 Randomized Cohort (Placebo) (Type: PLACEBO_COMPARATOR): Following review of safety and efficacy data from the Sentinel Cohort, participants will be randomized to receive placebo + their current failing ARV regimen for 10 days in Part 1.
- Part 2 E/C/F/TAF+ATV (Type: EXPERIMENTAL): Following a 14-day period to confirm eligibility, participants in the Randomized Cohort TAF group with a \> 0.5 log10 decline in HIV-1 RNA and all participants completing the Randomized Cohort Placebo group will receive E/C/F/TAF+ATV for 48 weeks in Part 2. After completion of Part 2, all participants will be eligible to continue to receive E/C/F/TAF plus ATV in the extension phase until E/C/F/TAF becomes commercially available, or until Gilead Sciences terminates development of E/C/F/TAF in the applicable country.

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