8. *VF is estimated by Kaplan Meier product limit method and log-Rank test is used for detecting treatment differences through Week 48 Virologic Failure* (HIV-1 RNA ? 200 c/mL) through Week 48

10. eGFR through 48 Weeks
11. 11 Fasting Lipids Change from Baseline Values at Week 48
12. 12 Conclusions Through 48 weeks, switching to FTC/TDF was non-inferior to remaining on 3TC/ABC
Significantly fewer subjects who switched to FTC/TDF experienced virologic failure compared to those who remained on 3TC/ABC through Week 48
Switching to FTC/TDF resulted in significant improvement in fasting LDL and TC
Declines in eGFR of unclear clinical significance were seen in both arms and were higher in the FTC/TDF arm
Switching to FTC/TDF was safe and well tolerated with similar AEs observed between arms
