MT204 is a humanized IgG1 antibody inhibitor targeting IL-2 of human and rhesus monkey origin. MT204 prevents soluble IL-2 from binding to intermediate-affinity IL-2 receptors and blocks CD25-bound IL-2 on high-affinity IL-2 receptors. MT204 has potently anti-proliferative activity with NKL cells and primary NK cells. MT204 has good tolerability and potent immunosuppressive activity in allogeneic skin graft model of rhesus monkey, promising for immunosuppressive and anti-proliferative therapy[1].
