达沙替尼有望用于治疗BRCA1突变型卵巢癌的治疗

2016-07-05 生物谷 生物谷

近日,百时美的白血病药物dasatinib(达沙替尼,商品名Sprycel)在扩大适应症方面取得了新进展,有研究表明,该药物具有治疗卵巢癌的潜力。 来自英国肿瘤研究所的研究者将达沙替尼用于具有BRCA1突变的卵巢癌小鼠模型,发现达沙替尼能够阻止肿瘤细胞的增殖。BRCA1是女性罹患乳腺癌和卵巢癌最重要的易感基因,整个卵巢癌患者群体中,BRCA1突变的患者约占总人数的25%,并且携带BRCA1突变的

近日,百时美的白血病药物dasatinib(达沙替尼,商品名Sprycel)在扩大适应症方面取得了新进展,有研究表明,该药物具有治疗卵巢癌的潜力。

来自英国肿瘤研究所的研究者将达沙替尼用于具有BRCA1突变的卵巢癌小鼠模型,发现达沙替尼能够阻止肿瘤细胞的增殖。BRCA1是女性罹患乳腺癌和卵巢癌最重要的易感基因,整个卵巢癌患者群体中,BRCA1突变的患者约占总人数的25%,并且携带BRCA1突变的卵巢癌患者相较无BRCA1突变的群体,疾病进展更为迅速。

研究者在携带BRCA1突变及不携带该突变的两种小鼠模型中验证了68种抗癌药的效果,发现达沙替尼能够有效抑制肿瘤的生长。该研究团队的负责人表示,下面将致力于在卵巢癌患者中验证达沙替尼的效果,一旦发现有效,达沙替尼便可以尽快用于卵巢癌的治疗。“老药新用”的强大优势在于,目前该药物已经在其它适应症中获批,安全性已经得到保证,因此研究者们将重点关注的是对新适应症的有效性。

达沙替尼是百时美施贵宝研发的口服抗癌药,2006年在欧洲获批,用于治疗慢性髓性白血病以及Ph+的急性淋巴细胞白血病。2009年5月达沙替尼获FDA批准,用于治疗各期慢性髓细胞白血病(CML)、对包括甲磺酸伊马替尼在内的治疗方案耐药或不能耐受的慢性髓细胞样白血病,以及费城染色体阳性(Ph+)的急性淋巴细胞白血病(Ph+ALL)。2010年,FDA批准其扩大适应症,用于治疗费城染色体阳性慢性髓细胞白血病(Ph+CP-CML)
