also superiority (P = 0.003, ITT) at 48 weeks and persisted to 96 weeks, 80% versus 72%, respectively (P = 0.006; 95% CI 2.3%, 13.8%). When stratified by VL >100,000 this difference was lost ABC/3TC/DTG is superior to FTC/TDF/EFV DTG statistically significant more rapid virologic decay compared to EFV No primary emerging resistance on DTG Flamingo [34] R, OL NI → Superiority Funding: ViiV Healthcare S: well-resourced countries D: non-white (28%); males 85%; x = 34 years; n = 484 IC: ≥18 years, naïve to ART, VL >1,000 c/mL OL: DTG 50 mg QD versus DRV/r 800 mg/100 mg QD with background either TDF/FTC or ABC/3TC. Stratified by VL ≤ or >100,000 c/mL (25% >100,000 c/mL) 1°EP: VL <50 c/mL at week 48 (NI margin −12%) Results: 48-week snapshot analysis showed 90 versus 83% had VL <50 c/mL. This demonstrated not only NI, but also S (P = 0.025; adjusted difference 7.1%; 95% CI 0.9–13.2). When stratified by those with VL >100,000 DTG superior to DRV/r 93% versus 70%, respectively. Fewer AE with DTG contributed to superiority. DTG had lower LDL values (2% versus 7%, these P < 0.001) and less diarrhea (17% versus 29%) DTG is

Pre-specified statistical criteria revealed NI of DTG to RAL (adjusted treatment difference greater than −12%) and superiority (P = 0.03 mITT-E analysis; 95% CI >0).
