B/F/TAF vs Atripla Double-Blind Switch Study in HIV-1 Infected Adults

• Status: Completed
• Trial end date: 2020-09-03
• Target enrollment: 0
• Participant gender: All

Summary

Atripla (ATP: FTC/TDF/EFV) was the first single pill treatment for HIV and was the most prescribed first-line treatment from approximately 2008 to 2013 for people infected with HIV. However, ATP has not been recommended as a "preferred" treatment for HIV since 2015, due to there now being single pill treatments that work better. There are a lot of people who are still taking ATP and it is working for them. However, it has the potential to cause serious side effects (chronic kidney disease and fractures and serious neurological effects). These side effects are caused by components in ATP (namely the TDF and EFV parts). Also, the efavirenz (EFV) component is not compatible for treatment of Hepatitis C (HCV) - which is often also seen in people who have HIV. For these reasons, there is a need to find a better alternative treatment for these people currently being treated with ATP.
