Study to Evaluate Switching From Regimens Consisting of a Ritonavir-boosted Protease Inhibitor (PI) and Two Nucleoside Reverse Transcriptase Inhibitors (NRTIs) to a Fixed-dose Tablet Containing Emtricitabine/Rilpivirine/Tenofovir DF

A Phase 3 Randomized, Open Label Study to Evaluate Switching From Regimens Consisting of a Ritonavir-boosted Protease Inhibitor and Two Nucleoside Reverse Transcriptase Inhibitors to Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate (FTC/RPV/TDF) Fixed-dose Regimen in Virologically Suppressed, HIV-1 Infected Patients

Summary

The purpose of this randomized, open-label, multicenter, active-controlled Phase 3b study is to evaluate the noninferiority of the emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF) single-tablet regimen (STR; also referred to as fixed-dose regimen or fixed-dose tablet) relative to regimens consisting of a ritonavir-boosted protease inhibitor (PI+RTV) and two nucleoside reverse transcriptase inhibitors (NRTIs) in virologically suppressed, HIV-1 infected subjects. The FTC/RPV/TDF STR could offer an attractive treatment option to patients who wish to simplify dosing by reducing pill burden or to improve the tolerability of their treatment. Participants will be randomized into 2 groups, the FTC/RPV/TDF STR group, in which participants will switch treatment regimens at the start of the study, and the Stay on Baseline Regimen (SBR)/Delayed Switch group, in which participants will remain on their baseline regimen during the first 24 weeks of the study (designed to provide an initial active control), and may switch to the FTC/RPV/TDF STR at the Week 24 visit. After the 48-week study analysis period, participants may continue to receive the FTC/RPV/TDF STR per protocol before switching to a commercially available source.
