TMC310911 is a novel human immunodeficiency virus type-1 (HIV-1) protease inhibitor (PI) structurally closely related to darunavir (DRV), but with improved virological characteristics. TMC310911 has potent antiviral activity against wild-type (WT) HIV-1 (median 50% effective concentration [EC(50)], 14 nM) and a wide spectrum of recombinant HIV-1 clinical isolates including multi PI-resistant strains with decreased susceptibility to currently approved PIs (fold change in EC(50) [FC]&gt;10). On a panel of 2011 recombinant clinical isolates with decreased susceptibility to at least one of the currently approved PIs, the FC in EC(50) for TMC310911 was &lt;/=4 for 82% of isolates, and &lt;/=10 for 96% of isolates. TMC310911 had a FC&lt;/=4 and a FC&lt;/=10 for 72% and 94% of isolates with a decreased susceptibility to DRV, respectively. In vitro resistance selection (IVRS) experiments with WT virus and TMC310911 selected for mutations R41G or R41E, but selection of resistant virus required a longer time than IVRS with WT virus and DRV. IVRS with a multi PI-resistant recombinant clinical isolate r13025 with TMC310911 selected for mutations L10F, I47V, and L90M (TMC310911 FC=16). IVRS with r13025 in the presence of DRV required less time and resulted in more PI resistance-associated mutations (V32I, I50V, G73S, L76V, and V82I, DRV FC=258). The antiviral activity against a comprehensive panel of PI-resistant mutants and the limited in vitro selection of resistant viruses under drug pressure suggest that TMC310911 represents a potential drug candidate for the management of HIV-1 infection for a broad range of patients, including those with multiple PI resistance.
