CHMP支持批准拜耳抗癌药Stivarga用于GIST的治疗

2014-07-02 佚名 生物谷

拜耳(Bayer)6月27日宣布,抗癌药Stivarga(regorafenib)获得了欧洲药品管理局(EMA)人用医药产品委员会(CHMP)的积极意见。CHMP建议批准Stivarga用于既往经2种酪氨酸激酶抑制剂(Gleevec、Sutent)治疗后病情恶化或不耐受的不可切除性或转移性胃肠道间质瘤(GIST)患者的治疗。欧盟委员会(EC)预计将于2014年第三季度做出最终审查决定。此前,Sti

拜耳(Bayer)6月27日宣布,抗癌药Stivarga(regorafenib)获得了欧洲药品管理局(EMA)人用医药产品委员会(CHMP)的积极意见。CHMP建议批准Stivarga用于既往经2种酪氨酸激酶抑制剂(Gleevec、Sutent)治疗后病情恶化或不耐受的不可切除性或转移性胃肠道间质瘤(GIST)患者的治疗。欧盟委员会(EC)预计将于2014年第三季度做出最终审查决定。此前,Stivarga于2013年8月30日获欧盟批准用于转移性结直肠癌(mCRC)的治疗。

CHMP的积极意见是基于关键III期GRID研究的数据。数据显示,与安慰剂+最佳支持疗法(BSC)相比,Stivarga+BSC组合疗法使无进展生存期(PFS)取得了统计学意义的显著改善(4.8个月 vs 0.9个月,p<0.0001)。

目前,Stivarga已获美国、欧盟、日本批准,用于转移性结直肠癌(mCRC)的治疗。同时,该药已获美国和日本批准用于治疗胃肠道间质瘤(GIST)。Stivarga是FDA批准的第三个治疗胃肠道间质瘤(GIST)的药物,另2个药物为诺华的格列卫(Gleevec)、辉瑞的索坦(Sutent)。

胃肠道间质瘤(GIST)是癌细胞发生在胃肠道的一种肿瘤,患者多为老年人。GIST,由于其极具侵略性的特点,目前依然是尚未满足的医疗需求,同时治疗的选择也很有限,相关临床研究数据表明,Stivarga有望为那些经标准治疗后复发的患者提供一种重要的治疗方案。

Stivarga是一种口服多激酶抑制剂,在临床前研究中,regorafenib能够抑制数个促血管生成VEGF受体酪氨酸激酶,这些激酶在肿瘤的血管生成中发挥着重要作用。该药还可以抑制癌和肿瘤微环境中的多种激酶,包括VEGFR 1-3, KIT, RET, PDGFR及FGFR。Stivarga由拜耳开发,由拜耳和Onyx制药联合推广。
