Abstract

Long-acting antiretrovirals can improve therapy and prevention for HIV-1 infection. Current long-acting cabotegravir (CAB LAP) can be administered every other month. Previously, we demonstrated that a myristoylated CAB prodrug encased in poloxamer 407 provided extended plasma drug concentrations. We now demonstrate that this first-generation nanoformulated prodrug can sustain plasma CAB concentrations above the protein-adjusted 90% inhibitory concentration for 4 months in rhesus macaques. A 2.5-fold extension in CAB half-life and a 1.6-fold increase in area under the concentration-time curve were observed compared with CAB LAP.
