Cynomolgus monkey is a suitable species to study the safety of ERY974. (a) Cytotoxicity assay for ERY974 using human PBMCs. (b) Cytotoxicity assay for ERY974 using cynomolgus monkey PBMCs. PBMCs from four independent donors are used as effector cells, and SK-pca13a was used as the target cell. Data are shown as mean ± SD (n = 3). (c) Summary of tissue cross-reactivity of ERY974 in human and cynomolgus monkeys. Frozen sections of various normal tissues from human and cynomolgus monkeys were stained with biotinylated ERY974. Tissues positive for ERY974 staining are shown with “P,” and tissues negative for ERY974 staining are shown with “-.” Cyno means cynomolugus monkey.
