强生的膀胱癌靶向治疗药物Balversa在美国获批

2019-04-15 不详 MedSci原创

强生的膀胱癌药物Balversa在美国获得批准,用于治疗成纤维细胞生长因子(FGFR)突变的膀胱癌患者。大约有五分之一的复发/难治性膀胱癌患者中存在FGFR基因突变。

强生的膀胱癌药物Balversa在美国获得批准,用于治疗成纤维细胞生长因子(FGFR)突变的膀胱癌患者。大约有五分之一的复发/难治性膀胱癌患者中存在FGFR基因突变。

FDA药物评估和研究中心血液学和肿瘤学主管Richard Pazdur说道:"我们正处于一个更加个性化或精准医学的时代,将癌症治疗针对患者的特定基因突变或生物标志物的能力正在成为新的评价标准。FGFR调节重要的生物过程,包括细胞生长和发育,和组织修复过程中的分裂。该药通过靶向FGFR基因突变发挥治疗作用。"

Balversa仅用于铂类化疗药物治疗期间或之后疾病进展的患者,去年9月获得FDA的突破性药物指定,从而获得了FDA的加速审批。

Balversa的临床试验显示该药物的总体响应率为32.2%,其中2.3%具有完全响应,近30%具有部分响应。该结果被认为是膀胱癌治疗领域的重大突破,因为大多数属于特定类型膀胱癌的患者对免疫治疗和检查点抑制剂(膀胱癌的护理标准)均没有反应。

强生全球治疗领域主管Peter Lebowitz说:"我们期待Balversa的继续发展,以探究该药物在FGFR基因突变的转移性尿路上皮癌中治疗潜力。"

Sci Rep:膀胱癌中组合光免疫疗法(PIT)靶向上皮生长因子受体(EGFR)和人类上皮生长因子受体2(HER2)研究

膀胱癌(BC)具有异质性特征并且能够表达各种各样的细胞表面靶标。光免疫治疗(PIT)中单克隆抗体(MAbs)与光吸收子(PA)共轭产生的组合物,之后通过近红外光(NIR)的激发从而特异性的靶向肿瘤。最近,有研究人员阐释了PIT可以靶向肿瘤表达的EGFR。然而,当单一的靶标(比如EGFR)表达不足是,PIT疗法效果并不是很理想。有研究人员探究了一种组合PIT治疗方法来靶向BC表达的EGFR和HER2
