Purpose of review: Although tremendous successes in HIV treatment and prevention have occurred in the past decade, existing HIV prevention options are inadequate, unacceptable or inaccessible to many. Topical antiretroviral-based preexposure prophylaxis (PrEP) options may offer effective, long-acting prevention to those who do not desire systemic exposure to anti-HIV drugs or who want greater control over their own prevention.
Recent findings: Among long-acting topical PrEP agents, the dapivirine vaginal ring has advanced the furthest in product development; recent studies have shown high adherence and persistence and evidence of HIV protection in open-label studies as well as a well tolerated safety profile, across the life cycle in women. A range of other long-acting topical PrEP products for vaginal or rectal drug delivery are under development. Rigorous end-user research has explored how to develop products that are behaviorally congruent for the population at risk and has shown that no single product option will be desired by all, but rather different options will achieve the greatest prevention coverage.
Summary: Topically delivered, long-acting antiretroviral PrEP options are being designed to align with user preferences and lifestyles, providing the potential to more effectively expand the HIV prevention method mix and use and achieve an important impact on HIV globally.
