A Phase 2/3, Open-Label Study of the Pharmacokinetics, Safety, and Antiviral Activity of the Elvitegravir/ Cobicistat/Emtricitabine/Tenofovir Disoproxil Fumarate Single Tablet Regimen (STR) in HIV-1 Infected Antiretroviral Treatment-Naive Adolescents

The primary objectives of this study are to evaluate the steady-state pharmacokinetics (PK)
and confirm the dose of the elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil
fumarate (EVG/COBI/FTC/TDF) single-tablet regimen (STR) (Part A) and to evaluate the safety
and tolerability of EVG/COBI/FTC/TDF STR through Week 48 (Part B) in HIV-1 infected,
antiretroviral (ARV) treatment-naive adolescents.

A total of 50 adolescent participants (12 to < 18 years of age) will be enrolled to receive
EVG/COBI/FTC/TDF as follows:

- Part A: Twelve to 16 eligible participants will be enrolled to evaluate steady-state PK,
and confirm the dose, with the intent to enroll at least 4 participants 12 to < 15 and
at least 4 participants 15 to < 18 years of age.

- Part B: Following confirmation of EVG exposure in at least 12 participants from Part A,
34 to 38 participants in addition to those enrolled in Part A will be enrolled to
evaluate the safety, tolerability, and antiviral activity of EVG/COBI/FTC/TDF STR.

squamous carcinoma

- Have previously participated in an investigational trial involving administration of
any investigational agent within 30 days prior to the study dosing

- Participation in any other clinical trial without prior approval from sponsor is
prohibited while participating in this trial

- Receiving ongoing therapy with any disallowed medications, including drugs not to be
used with EVG, COBI, FTC, TDF or individuals with any known allergies to the
