中文名称:阿维鲁单抗中文同义词:阿维鲁单抗英文名称:Avelumab英文同义词:Avelumab;Avelumab (anti- PD-L1)产品描述该类似物是一种程序性死亡配体1 (PD-L1) 阻断抗体,是一种人源IgG1单克隆抗体,其分子量约为147 kDa,由中国仓鼠卵巢细胞生产。 性质Name Biosimilar of AvelumabCAS NO. 1537032-82-8Type Whole antibodySource HumanTarget PD-L1Clone MonocloneMolecular Weight 147 kDaAntibody Form Purified immunoglobulinPhysical Form SolutionGrade Standard Medicine GradeStorage -70±15℃ for long-term storage, 2-8℃ for short-term storage, away from light.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).(对鼠类PD-L1有高亲和性和活性)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) 小鼠 大鼠 兔 豚鼠 仓鼠 狗重量 (kg) 0.02 0.15 1.8 0.4 0.08 10体表面积 (m2) 0.007 0.025 0.15 0.05 0.02 0.5Km 系数 3 6 12 8 5 20动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数动物 A的Km系数例如,依据体表面积折算法,将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量,需要将22.4 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。储备液配制以下数据基于产品分子量,对于特殊产品,请参照COA中的储备液配制条件和说明进行操作。Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg1 mM 0.007 mL 0.0348 mL 0.0695 mL5 mM 0.0014 mL 0.007 mL 0.0139 mL10 mM 0.0007 mL 0.0035 mL 0.007 mL参考文献Systemic Immunotherapy of Non-Muscle Invasive Mouse Bladder Cancer with Avelumab, an Anti-PD-L1 Immune Checkpoint Inhibitor.Vandeveer AJ, et al.
