曾用名:

简介:近日,美国食品和药物管理局批准加速批准IMFINZI(durvalumab)治疗局部晚期或转移性尿路上皮癌患者,在铂类化疗期间或之后患有疾病进展或患有新辅助或辅助治疗12个月内用含铂化疗治疗疾病进展。Durvalumab是一种程式死亡配体1(PD-L1)阻断抗体,程式细胞死亡配体-1(PD-L1)的表达可能被炎症信号诱导(如,IFN-gamma),和可能被表达在肿瘤细胞和在肿瘤微环境中肿瘤-关联免疫细胞上。PD-L1阻断T-细胞功能以及通过PD-1和CD80(B7.1)

作用相互活化

通过结合至它的受体,PD-L1减低细毒性T-细胞的活性,增殖,和细胞因数的产生。在同种移植的人类肿瘤和免疫细胞异种移植小鼠模型中,durvalumab阻断PD-L1能增加T-细胞的活化作用,减低肿瘤大小。批准日期:2017年5月1日公司:阿斯利康公司IMFINZI(durvalumab)注射液,用于静脉注射美国最初批准:2017年最近的重大变

警告和注意事项:

02/2018作用机制程序性细胞死亡配体-1(PD-L1)的表达可以由炎性信号(例如,IFN-γ)诱导,并且可以在肿瘤微环境中的肿瘤细胞和肿瘤相关免疫细胞上表达。PD-L1通过与PD-1和CD80的相互作用阻断T细胞功能和活化(B7.1)。通过与其受体结合,PD-L1降低细胞毒性T细胞活性,增殖和细胞因子产生。Durvalumab是一种人免疫球蛋白G1kappa(IgG1κ)单克隆抗体,可与PD-L1结合并阻断PD-L1与PD-1和CD80的相互作用(B7.1)。阻断PD-L1/PD-1和PD-L1/CD80相互作用释放免疫应答的抑制,而不诱导抗体依赖性细胞介导的细胞毒性(ADCC)。使用durvalumab的PD-L1阻断导致体外T细胞活化增加并且共同移植的人肿瘤和免疫细胞异种移植小鼠模型中的肿瘤尺寸减小。

度伐单抗注射剂英文版说明书

Imfinzi will be available in single-dose vials in 500mg/10mL or 120mg/2.4mL strengthsPD-L1 expression: The role of programmed cell death ligand-11Expression of programmed cell death ligand-1 (PD-L1) can be induced by inflammatory signals (eg, IFN-gamma) and can be expressed on both tumor cells and tumor-associated immune cells in tumor microenvironment. PD-L1 blocks T-cell function and activation through interaction with PD-1 and CD80 (B7.1). By binding to its receptors, PD-L1 reduces cytotoxic T-cell activity, proliferation, and cytokine production.Although testing is not required, knowing your patient’s PD-L1 expression status may aid in treatment selection and help manage patientIMFINZI mechanism of action1Durvalumab is a human immunoglobulin G1 kappa (IgG1κ) monoclonal antibody that blocks the interaction of PD-L1 with PD-1 and CD80 (B7.1). Blockade of PD-L1/PD-1 and PD-L1/CD80 interactions releases the inhibition of immune responses, without inducing antibody dependent cell-mediated cytotoxicity (ADCC).PD-L1 blockade with durvalumab led to increased T-cell activation in vitro and decreased tumor size in co-engrafted human tumor and immune cell xenograft mouse models.Important Safety InformationThere are no contraindications for IMFINZITM (durvalumab).Monitor patients for clinical signs and symptoms of immune-mediated pneumonitis, hepatitis, colitis or diarrhea, endocrinopathies, nephritis, rash or dermatitis, and other immune-mediated adverse reactions.
