A Phase 2/3, Open-Label, Multi-Cohort Switch Study to Evaluate Emtricitabine/Tenofovir Alafenamide (F/TAF) in HIV-1 Infected Children and Adolescents Virologically Suppressed on a 2-NRTI-Containing Regimen

This study will evaluate the pharmacokinetics (PK), safety, and efficacy of
emtricitabine/tenofovir alafenamide (F/TAF) in HIV-1 infected children and adolescents
virologically suppressed (defined as having < 50 copies/mL of HIV-1 RNA for a period of at
least 6 months) while on a stable 2-nucleoside/nucleotide reverse transcriptase inhibitor
(NRTI) containing regimen.

Cohorts 2, 3, and 4 will be on a boosted protease inhibitor (PI) or any other 3rd ARV agent
and will switch their current 2-NRTI-containing regimen to open-label F/TAF while continuing
their boosted PI or 3rd agent through 48 weeks. A minimum of 10 participants each in Groups 1
and 2 of Cohort 2, and Cohorts 3 and 4, who are on boosted-ATV as their 3rd ARV agent will be
enrolled. Participants in Cohort 2, Group 1 receive boosted PI agents only. Cohorts 2, 3, and
4 will be enrolled by cohort into a two-part study (Parts A and B).

After completion of 48 weeks, all participants will be given the option to participate in an
extension phase of the study. Gilead will provide F/TAF until a) The participant turns 18
years old and F/TAF is commercially available for use in adults in the country in which the
participant is enrolled or b), F/TAF becomes commercially available for pediatric use in the
country in which the participant is enrolled or c), Gilead Sciences elects to terminate
development of F/TAF in the applicable country.

Investigator, would interfere with treatment, assessment, or compliance with the
protocol.
