生物活性

Avelumab 是一种独特的强ADCC活性的PD-L1全人源化抗体，能有效地阻止PD-L1与PD-1的结合。Formation of a PD-1/PD-L1 receptor/ligand complex leads to inhibition of CD8+ T cells, and therefore inhibition of an immune reaction. Immunotherapy aims at ceasing this immune blockage by blocking those receptor ligand pairs. In the case of avelumab, the formation of PD-1/PDL1 ligand pairs is blocked and CD8+ T cell immune response should be increased. PD-1 itself has also been a target for immunotherapy. Therefore, avelumab belongs to the group of immune checkpoint blockade cancer therapies. By retaining a native Fc-region, avelumab is thought to engage the innate immune system and may induce antibody-dependent cell-mediated cytotoxicity (ADCC).

Avelumab可以识别鼠 PD-L1（对鼠类PD-L1有高亲和性和活性）

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
