中文名稱:阿維魯單抗中文同義詞:阿維魯單抗英文名稱:Avelumab英文同義詞:Avelumab;Avelumab (anti- PD-L1)產品描述該類似物是一種程序性死亡配體1 (PD-L1) 阻斷抗體,是一種人源IgG1單克隆抗體,其分子量約為147 kDa,由中國倉鼠卵巢細胞生產。 性質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 是一種獨特的強ADCC活性的PD-L1全人源化抗體,能有效地阻止PD-L1與PD-1的結合。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).(對鼠類PD-L1有高親和性和活性)不同實驗動物依據體表面積的等效劑量轉換表(數據來源于FDA指南) 小鼠 大鼠 兔 豚鼠 倉鼠 狗重量 (kg) 0.02 0.15 1.8 0.4 0.08 10體表面積 (m2) 0.007 0.025 0.15 0.05 0.02 0.5Km 系數 3 6 12 8 5 20動物 A (mg/kg) = 動物 B (mg/kg) × 動物 B的Km系數動物 A的Km系數例如,依據體表面積折算法,將白藜蘆醇用于小鼠的劑量22.4 mg/kg 換算成大鼠的劑量,需要將22.4 mg/kg 乘以小鼠的Km系數(3),再除以大鼠的Km系數(6),得到白藜蘆醇用于大鼠的等效劑量為11.2 mg/kg。儲備液配制以下數據基于產品分子量,對于特殊產品,請參照COA中的儲備液配制條件和說明進行操作。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參考文獻Systemic Immunotherapy of Non-Muscle Invasive Mouse Bladder Cancer with Avelumab, an Anti-PD-L1 Immune Checkpoint Inhibitor.Vandeveer AJ, et al.
