Mogamulizumab (TAB-187)

Recombinant monoclonal antibody to CCR4. Mogamulizumab (USAN; trade name Poteligeo) is a humanized monoclonal antibody targeting CC chemokine receptor 4 (CCR4). It has been approved in Japan for the treatment of relapsed or refractory adult T-cell leukemia/lymphoma.

Figure 1 Mogamulizumab eliminates CCR4 + cells in both CD4 + and CD8 + T cells.

A, Representative dot plots of fluorescence-activated cell-sorter analysis of CCR4 and CD4 expression in CD3 + T cells among peripheral blood mononuclear cells from patients with human T-lymphotropic virus type 1–asso- ciated myelopathy/tropical spastic paraparesis after 5-day culture in the presence or absence of 1 µg/mL of mogamulizumab. B, Percentages of CCR4 + cells in CD3 + CD4 + T cells were compared between the untreated and mogamulizumab groups (n = 11). Statistical analysis was performed using the Wilcoxon signed-rank test. C, The population enclosed in the box in panel A (the CD3 + CD4 − CCR4 + subset) was gated and analyzed for the expression of CD8. The percentage of CD8 + cells is shown. D and E, CCR4 and CD8 expression in CD3 + T cells was analyzed as described above.

Figure 2 Mogamulizumab and KM2760 inhibit cytokine production in peripheral blood mononuclear cells (PBMCs) from patients with human T-lymphotropic virus type 1–associated myelopathy/tropical spastic paraparesis (HAM/TSP).

PBMCs from 11 patients with HAM/TSP were cultured for 7 days without stimuli and without treatment or in the presence of mogamulizumab, KM2760, or prednisolone (PSL). The concentrations of cytokines (interferon γ [IFN-γ], interleukin 6 [IL-6], interleukin 2 [IL-2], tumor necrosis factor α [TNF-α], and interleukin 10 [IL-10]) in the supernatants were then measured. A, Direct comparison of the concentrations of these cytokines in the supernatants of untreated PBMC cultures. Horizontal bars represent the median values. B–F, The effects of the treatments on the concentrations of these cytokines. Data are presented as the mean ± SD. Statistical analyses were performed using the Friedman test followed by the Dunn test for comparison with PBMCs alone. *P < .05, **P < .01, and ***P < .001. Abbreviation: SD, standard deviation.

Figure 3 Mogamulizumab-induced ADCC. A, four CCR4-positive and three CCR4-negative cell lines were examined.

Cytotoxicity was measured using the LDH assay in the presence of effector cells obtained from healthy volunteers and mogamulizumab (10 μg/mL) or the same volume of solvent (control). B, dose-dependent effects of mogamulizumab against SNK6. Various doses of mogamulizumab and PBMCs from three healthy individuals were prepared. The ratio of target:effector was fixed at 1:50. C, identification of the fraction responsible for ADCC against SNK6. Separated CD56-, CD3-, and CD19-positive cells were used as effector cells, respectively. The ratio of target:effector was fixed at 1:10. The mogamulizumab dose was fixed at 10 μg/mL. Error bars, SEM.

Figure 4 Mogamulizumab induced potent antitumor activity against EBV-positive NK-cell lymphoma in the murine xenograft model.

A, NOG mice were implanted subcutaneously with SNK6 cells on day 0. From day 4, human PBMCs with mogamulizumab or saline (control) were injected intraperitoneally (6 mice per group). *, P < 0.05 (Mann–Whitney U test). Error bars, SEM. B, tumor-bearing mice at day 28.

Figure 5 Immunohistochemistry of CCR4 in patients with PTCL.

CCR4 expression level in patients with PTCL varies in each case. CCR4 expression level is immunohistochemically evaluated in three grades. 1+: 10–24% of tumor cells are positive for CCR4 (a, ×400), 2+: 25–49% of tumor cells are positive for CCR4 (b, ×400), and 3+: 50% or more tumor cells are positive (c, ×400).Abbreviations: CCR4 CC chemokine receptor 4; PTCL peripheral T-cell lymphoma.
