Although, single-tablet regimen (STR) efavirenz, emtricibine, and tenofovir disoproxil fumarate (EFV/FTC/TDF) may be appealing in HIV-infected persons who are at high risk for nonadherence, the degree to which this simplified formulation affects adherence is not known. The virologic effectiveness of this STR in a potentially nonadherent population remains a concern, given the rapid selection of drug resistance seen with these drugs.


We performed a prospective observational study assessing adherence and virologic response to EFV/FTC/TDF STR among a cohort of homeless and marginally housed individuals. We compared adherence and viral suppression to historical controls followed in the same cohort.


Adherence was higher in EFV/FTC/TDF STR regimen compared to non-one-pill-once-daily therapy (P = 0.006) after controlling for multiple confounders. Viral suppression (HIV RNA <50 copies/ml) was greater in EFV/ FTC/TDF STR than non-one-pill-once-daily regimens (69.2 versus 46.5%; P = 0.02), but there was no difference in viral suppression after controlling for adherence.


Once-daily EFV/TNF/FTC STR appears to be a reasonable option for individuals with multiple barriers to adherence. Randomized clinical trials addressing various therapeutic strategies for this patient population are needed.
