Switch From Dual Regimens Based on Dolutegravir Plus a Reverse Transcriptase Inhibitor to E/C/F/TAF in Virologically Suppressed, HIV-1 Infected Patients (Be-OnE)

Summary

Research hypothesis: Switching from dual regimens based on dolutegravir plus a RTI to a single tablet regimen of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF), lowers the exposure to Residual Viremia (and hence the risk of viral rebound), without increasing treatment toxicity.

Stopped: “The futility analysis on 24-week results estimated that there was only 2% probability of verifying the study hypothesis of a higher proportion pat. with no residual viremia through 48w in arm E/C/F/TAF”
