A previous study demonstrated that EVG\/COBI\/FTC\/TDF was noninferior at 48 weeks when compared with coformulated efavirenz (EFV), FTC, and TDF (EFV\/FTC\/TDF) as initial therapy [Sax P et al. \u003Cem\u003ELancet\u003C\/em\u003E. 2012]. Another study showed that EVG\/COBI\/FTC\/TDF, when compared with the ritonavir-boosted (RTV) protease inhibitor regimen of atazanavir (ATV) plus coformulated FTC\/TDF (RTV-ATV\/FTC\/TDF) for initial therapy, was noninferior for the primary outcome of HIV RNA concentration of \u2264 50 copies\/mL at 48 weeks [DeJesus E et al. \u003Cem\u003ELancet\u003C\/em\u003E. 2012].

These rates were 79%, 75%, and 75% at week 144, respectively. Outcomes were consistent across demographics and baseline HIV-1 RNA and CD4 levels.

Most of the resistance occurred in the first 24 to 48 weeks. There were relatively few adverse events (AEs). Diarrhea, upper respiratory infection, and nausea were the most frequent AEs. AEs leading to discontinuation were similar among the groups (about 7%), and discontinuation due to renal toxicity was infrequent. There were no new cases of proximal tubulopathy and no further increases in serum creatinine. Increases in creatinine usually occurred in the first 4 to 6 weeks.
