Pharmacokinetics Safety and Antiviral Activity of the Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (E/C/F/TAF) Single Tablet Regimen (STR) in HIV-1 Infected Antiretroviral Treatment-Naive Adolescents and Virologically Suppressed Children


Brief description of study

There will be 3 cohorts in this study.

The primary objectives of Cohort 1 are to evaluate the steady state pharmacokinetics (PK) for elvitegravir (EVG) and tenofovir alafenamide (TAF) and confirm the dose of the elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) single tablet regimen (STR) (Part A) and to evaluate the safety and tolerability of E/C/F/TAF STR through Week 24 (Part B) in HIV-1 infected, antiretroviral (ARV) treatment-naive adolescents.

The primary objectives of Cohort 2 are to evaluate the PK of EVG and TAF in virologically suppressed HIV-1 infected children 6 to < 12 years of age weighing 25 kg administered E/C/F/TAF STR (Part A) and to evaluate the safety and tolerability of E/C/F/TAF STR through Week 24 in virologically suppressed HIV-1 infected children 6 to < 12 years of age weighing 25 kg (Part B).

The primary objectives of cohort 3 are to evaluate the PK of EVG and TAF and confirm the dose of the STR, and to evaluate the safety and tolerability of E/C/F/TAF low dose (LD) STR in virologically suppressed HIV-1 infected children 2 years of age and weighing 14 to < 25 kg.
