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


Infectious Diseases : HIV infections


This study is phase II that involves an experimental combination drug named Elvitegravir/ Cobicistat/Emtricitabine/Tenofovir Disoproxil Fumarate single tablet for the treatment of HIV-1 infection adolescents who have never been treated before. Elvitegravir (EVG) and Cobicistat (COBI) are the two experimental drugs. The purpose of this study is to find out the concentration of the study drug in the body. Researchers will measure the amount of the study drug in the blood and determine how the body absorbs, distributes, metabolizes (processes), and eliminates (removes) it. They will also look at safety of this combination and how well it works.
