Anti-CCR5 ADCC Enhanced Antibody (HGS004) is an ADCC enhanced antibody produced by our Afuco™ platform. HGS004 is a human immunoglobulin (Ig) G4 monoclonal antibody against CCR5. HGS004 binds to and inhibits the activity of the CCR5 receptor on the cell surface. HIV uses both the CCR5 and the CD4 receptors to gain entry to the cell, but CCR5 is the primary receptor enabling HIV transmission and replication from the early stages of infection through to progression to AIDS.

Figure 2 Significant reductions in HIV-1 RNA were observed only in the higher-dose cohorts (8, 20, and 40 mg/kg)
A, Mean HIV-1 RNA reduction observed during a 56-day period in patients receiving a single intravenous infusion of HGS004 (0.4, 2, 8, 20, or 40 mg/kg), compared with placebo. B, HIV-1 RNA reduction in individual subjects receiving the maximum single intravenous dose of 40 mg/kg. DM refers to the 3 subjects who had dual/mixed (CXCR4/CCR5)-tropic isolates detected during the study.

Figure 6 Antiviral interactions between HGS004 and MVC versus HGS004 and RAL against R5 HIV-1 in primary cells.
PHA-activated PBMCs infected with HIV-1 BaL (a) or HIV-1 CC1/85 (b) using an MOI of 0.001 were cultured in the presence of the indicated drug concentrations. Virus production was measured on day 7 by p24 ELISA. Inhibition data from replicates were plotted using GraphPad Prism software and EC50 values determined using variable slope non-linear regression analysis. MVC EC50s for BaL and CC1/85 were 0.74 and 0.34 nM, respectively; whereas RAL EC50s for BaL and CC1/85 were 4.3 and 1.1 nM, respectively (not shown). Upper panels: Dose response curves for HGS004, alone and in combination with MVC or RAL. At each MVC or RAL concentration, p24 inhibition by HGS004 was normalized to inhibition by MVC or RAL alone. Data points are means ± S.D. of duplicates. Lower panels: Three-dimensional analysis of viral inhibition by drug combinations. Percentage synergy obtained by each combination was plotted against HGS004 and MVC or RAL concentrations according to Prichard's synergy model. The 96% confidence interval synergy plots are shown. Percentage synergies at each 10% increment are shown in different color intensities. Note that the synergy plots included more drug concentrations than those shown in dose response curves. Data are representative of three independent experiments for BaL and two independent experiments for CC1/85, with PBMCs from different donors in each experiment.
