抗癌药乐伐替尼新适应症获欧洲药品管理局人用药品委员会的积极意见 与依维莫司联合用药治疗晚期肾细胞癌
2016年7月22日，欧洲药品管理局人用药品委员会（CHMP）对抗癌药甲磺酸乐伐替尼（通用名：乐伐替尼）的积极意见，其与依维莫司联合用药，治疗既往接受过血管内皮生长因子靶向疗法的晚期肾细胞癌成人患者。
如果获批，乐伐替尼将针对此适应症以Kisplyx作为商品名上市。
CHMP的积极意见主要基于一项评估乐伐替尼与依维莫司联合使用，治疗既往接受过血管内皮生长因子靶向疗法的患有不可切除的晚期或转移性肾细胞癌患者的安全性和有效性的II期临床研究（205试验）。
研究结果显示，与单独使用依维莫司治疗组相比，联合使用乐伐替尼和依维莫司治疗组的无进展生存期（研究主要终点）显著延长，且客观缓解率提高。乐伐替尼与依维莫司联合用药治疗组最常见的治疗中出现的不良反应包括腹泻、食欲不振和疲劳。
最常见的3级或以上的治疗中出现的不良反应包括腹泻、高血压和疲劳。
欧洲约有11.5万例肾细胞癌患者，肾细胞癌在所有肾癌患者中的比例超过90%。对于难以通过手术进行治疗的晚期或转移性肾细胞癌，标准疗法为分子靶向药物，但5年生存率很低，仍是一种亟需新的治疗选择的疾病。
目前，乐伐替尼已在美国、日本、欧洲，作为难治性甲状腺癌治疗药物，以Lenvima?为商品名上市。
另外，2016年5月，乐伐替尼在美国被FDA批准与依维莫司联合用药，治疗既往接受过血管内皮生长因子靶向疗法的晚期肾细胞癌患者。
Kisplyx将作为4毫克和10毫克/硬胶囊

Kisplyx (lenvatinib) in Combination with everolimus Receives Positive CHMP Opinion in Advanced Renal Cell Carcinoma
About Lenvatinib's Novel Binding Mode (Type V)
Kinase inhibitors are categorized into several types (Type I to Type V) depending on the binding site and the conformation of the targeted kinase in complex with them. Most of the currently approved small molecule kinase inhibitors are either Type I or Type II, however lenvatinib was found to possess a new binding mode (Type V) of kinase inhibition that is distinct from existing compounds. In addition, lenvatinib was confirmed via kinetic analysis to exhibit rapid and potent inhibition of kinase activity, and it is suggested that this may be attributed to its novel binding mode.
About Everolimus
Everolimus is a selective mTOR (mammalian target of rapamycin) inhibitor. mTOR is a key serine-threonine kinase, the activity of which is known to be upregulated in a number of human cancers.
About Advanced Renal Cell Carcinoma
Renal cell carcinoma originates in the lining of the tubules,[9] the very small tubes in the kidney along with other parts of the nephron are involved in the blood filtration process to remove waste products.
