Mechanism of Action

Targets/IC₅₀/Ki	HIV reverse transcriptase ^[1] 24 nM
In vitro	Dapivirine (TMC120) prevents HIV-induced syncytium formation in the nanomolar range and shows a low cytostatic activity. It apparently blocks HIV-1 infection in the primary cultures at a 10 nM concentration, but secondary cultures reveals that a 100 nM concentration is needed to completely prevent proviral integration. ^[1] This compound is well tolerated by epithelial cells, T cells, macrophages, and cervical tissue explants with CC50 (50% cytotoxic concentration) of 10 μM to 20 μM. It potently inhibits infection by both X4- and R5-utilizing HIV-1 strains with IC50 of 1.46 nM in cell-based assays. Dapivirine potently inhibits HIV-1BaL infection of human ectocervical explant tissue in a dose-dependent manner, as evaluated by the reduction in both p24 release and provirus content in cultured explants. It inhibits the transmission of virus to permissive T cells in a dose-dependent manner, with an IC50 of 0.1 nM. This compound results in significant inhibition of HIV infection when explants are challenged with virus immediately with IC90 of 100 nM. It is also able to inhibit viral dissemination by migratory cells. ^[2]
In vivo	Dapivirine (TMC120)-containing gel at vaginal level inhibits cell-associated HIV infection in mice. ^[3] More placebo (7 of 12) than this compound (3 of 24) gel users has positive vaginal swab results, with white blood cells being the most common finding. It results in Cmax of 715 pg/mL, AUC of 15 ng×h/mL and T1/2 of 89.87 hours in plasma after 14 days post-dose. Mean concentrations of this compound (0.05%) in vaginal fluids collected at the introitus, mid vagina, and cervix are in the range of 62-265 μg/g on day 1. ^[4]
