Notes: Rilpivirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that inhibits growth of wild-type HIV with an EC50 value of 0.51 nM.{35241} It is active against NNRTI-resistant HIV strains with EC50 values less than 1 nM for L100I, K103N, V106A, G190A, and G190S mutants in vitro. Rilpivirine also reduces growth of greater than 80% of 1,500 NNRTI-resistant clinical isolates (EC50s = In vivo, rilpivirine, when used in combination with cabotegravir, lamivudine (Item No. 18514), and abcavir, reduces the plasma viral titer in HIV-1 infected humanized mice.{35242}
