HGS101
HGS101 is a fully human CCR5 monoclonal antibody with high affinity to CCR5. HGS101 binds to the 2nd extracellular loop (ECL-2) and acts as a signal antagonist. HGS101 restores Maraviroc (HY-13004) inhibition of Maraviroc-resistant HIV-1 infection of PBMCs. HGS101 shows anti-HIV activity by inhibiting CCR5 signaling in simian immunodeficiency virus-uninfected RMs models.

HGS101 (1 h) shows EC50 values of 0.001 μg/mL for Maraviroc (HY-13004)-sensitive, 0.0003 μg/mL for Maraviroc-resistant, and 0.00002 μg/mL for Maraviroc-resistant HIV-1 in the presence of Maraviroc in JC6 cells[1].
HGS101 (1 h) shows EC50 values of 0.03 μg/mL for Maraviroc-sensitive, 0.03 μg/mL for Maraviroc-resresistant, and 0.01 μg/mL for Maraviroc-resistant HIV-1 in the presence of Maraviroc in PBMCs[1].
HGS101 (0.3 µg/ mL, 1 h) restores Maraviroc inhibition (EC50 of 0.007 nM) of Maraviroc-resistant HIV-1 in PBMCs[1].
