       11月29日,美国食品药品监督管理局(FDA)批准了cabozantinib (Cometriq)用于治疗转移性甲状腺髓样癌,尽管该药物在临床试验中并未延长患者的总生存期。很显然,FDA对这种又名XL184的广谱激酶抑制剂在临床试验中显著的PFS(无进展生存期)益处和轻微毒性反应很满意。       &

       11月29日,美国食品药品监督管理局(FDA)批准了cabozantinib (Cometriq)用于治疗转移性甲状腺髓样癌,尽管该药物在临床试验中并未延长患者的总生存期。很显然,FDA对这种又名XL184的广谱激酶抑制剂在临床试验中显著的PFS(无进展生存期)益处和轻微毒性反应很满意。

       FDA药品评价和研究中心(CDER)的肿瘤/血液学负责人Richard Pazdur博士在宣布该药物的批准报告时表示,Cometriq是过去2年内FDA批准的第二个用于甲状腺髓样癌治疗的药物,由此可见FDA对罕见疾病药物发展的重视。在该药和2011年4月批准的Caprelsa(凡德他尼)之前,这种罕见疾病的患者的治疗方法非常有限。

       在纳入了330例患者的关于cabozantinib的研究显示,cabozantinib组患者的PFS为11.2个月,而安慰剂组为4个月。结果还显示,cabozantinib组有27%的患者肿瘤体积在15个月的时间里有所缩小,而安慰剂组肿瘤未出现体积缩小。不过,cabozantinib组患者的总生存期没有延长。

       FDA警告cabozantinib组的一些患者出现结肠穿孔和结肠瘘。该药物最常见的不良反应有腹泻、黏膜炎、手足综合征、厌食、恶心、乏力、口腔疼痛、头发变白、味觉不适、出现或加重高血压、腹痛和便秘等。部分患者的实验室检查出现异常,包括肝酶增加,钙磷水平降低,血小板减少和白细胞减少。

       Cabozantinib也有用于晚期前列腺癌和卵巢癌的相关研究。
