Design Endpoints –Primary: proportion of patients maintaining HIV RNA 0, assessment for superiority –Secondary: proportion of patients maintaining HIV RNA < 50 c/mL at W48 (TLOVR algorithm), CD4, safety, tolerability to W96 Switch to EVG/c/FTC/TDF Continue PI/r + FTC + TDF Arribas J.R. Lancet Infect Dis 2014;14:581-9 STRATEGY-PI Randomisation 2 : 1 Open-label HIV+ ≥ 18 years On FTC + TDF + PI/r HIV RNA 6 months No virologic failure Genotype testing before ART with no resistance to study drugs Integrase inhibitor naïve eGFR > 70 mL/min N = 145 N = 293 W48W96 STRATEGY-PI Study: Switch PI/r to EVG/c

Conclusion –Coformulated EVG/c/FTC/TDF is an effective, safe, and tolerable simplification from a PI/r plus FTC and TDF regimen in virologically suppressed, HIV-infected adults with no history of virological failure or resistance to FTC or TDF –Low frequency of virologic failure and absence of emergent resistance in the group switched to EVG/c/FTC/TDF –Rare discontinuations because of adverse events –Nausea more frequent in the switch group ; diarrhea and bloating improved –Small increase in creatinine, moderate improvement in lipids –EVG/c/FTC/TDF is a switch option in virologically suppressed patients with no history of virological failure who want to simplify their existing PI/r regimen, or who have concerns about the long-term safety and side-effects of their existing regimen Arribas J.R.
