An effective vaginal microbicide could reduce human immunodeficiency virus type 1 (HIV-1) transmission to women. Among microbicide candidates in clinical development is Maraviroc (MVC), a small molecule drug that binds the CCR5 co-receptor and impedes HIV-1 entry into cells. Delivered systemically, MVC reduces viral load in HIV-1-infected people, but its ability to prevent transmission is untested. We have now evaluated MVC as a vaginal microbicide, using a stringent model involving challenge of rhesus macaques with a high-dose of a CCR5-using virus, SHIV-162P3. Gel-formulated, prescription-grade MVC provided dose-dependent protection, half-maximally at 0.5 mM (0.25 mg/ml). The duration of protection was transient; the longer the delay between MVC application and virus challenge, the less protection (T1/2 ~ 4 h). As expected, MVC neither protected against challenge with a CXCR4-using virus, SHIV-KU1, nor exacerbated post-infection viremia. These findings validate MVC development as a vaginal microbicide for women, and should guide clinical programs.
