Oral Cabotegravir + Rilpivirine versus Efavirenz + 2 NRTI’s LATTE Study: Conclusions Interpretation : “ Cabotegravir plus dual NRTI therapy had potent antiviral activity during the induction phase. As a two drug maintenance therapy, cabotegravir plus rilpivirine provided antiviral activity similar to efavirenz plus dual NRTIs until the end of week 96. Combined efficacy and safety results lend support to our selection of oral cabotegravir 30 mg once a day for further assessment. LATTE precedes studies of the assessment of long-acting injectable formulations of both drugs as a two-drug regimen for the treatment of HIV-1 infection .” Source: Margolis DA, et al.
