Imvotamab (IGM-2323) is a CD20xCD3 bispecific IGM antibody with dual action mechanism. Imvotamab is used to induce physiological T cell activation to prevent over-stimulation and subsequent down-regulation of immune function. Imvotamab is currently being developed for the treatment of B-cell malignant tumors, multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL)[1][2][3][4].

In Vitro	Imvotamab (1-10000 pM) 对利妥昔单抗耐药 ramos 细胞具有杀伤作用[5]。 Imvotamab (0.1-1000 pM) 对 standard ramos 细胞具有杀伤作用[5]。 Imvotamab (1-1000 pM) 显著减少了细胞激素释放症候群中 IL-6、IL-2、IFNγ 和 TNFα 的含量[5]。
In Vivo	Imvotamab (0.001-10 mg/kg；单剂量) 显著减少了食蟹猴体内的 B 细胞百分比[5]。 Imvotamab (25 mg/kg) 在非人灵长类动物中促进了脾脏和淋巴组织中的 B 细胞耗竭，且没有显著的不良影响[5]。
