重磅里程碑:肺癌创新药第三代ALK抑制剂洛拉替尼在中国获批

2022-04-29 辉瑞 辉瑞

洛拉替尼为患者无进展生存期(PFS)带来重大突破,更强穿透血脑屏障,更少耐药

2022年4月29日,辉瑞公司宣布全球首个第三代ALK抑制剂博瑞纳®(Lorbrena®,通用名:洛拉替尼片/Lorlatinib Tablets)获国家药品监督管理局批准,单药适用于间变性淋巴瘤激酶(ALK)阳性的局部晚期或转移性非小细胞肺癌(NSCLC)患者的治疗。辉瑞创新肺癌靶向药物博瑞纳®为患者无进展生存期(PFS)带来重大突破,更强穿透血脑屏障,更少耐药,被最新国际指南推荐为一线优选治疗,重塑现有治疗格局,为ALK阳性晚期非小细胞肺癌患者带来长久获益。

“今天我们达成了ALK阳性晚期NSCLC治疗史上又一重大里程碑!随着博瑞纳®这一突破性创新疗法的获批,患者将获得更长更高质量的生存,这是辉瑞践行‘为患者带来改变其生活的突破创新’使命的又一例证。”辉瑞生物制药集团中国区总裁彭振科表示:“辉瑞肿瘤秉持‘科学致胜,共克癌症’的理念,持续为肿瘤治疗提供创新药物,积极促进国内肿瘤诊疗事业发展,我们相信,在与各界的共同努力下,我们终将战胜癌症这一严重威胁人类健康的疾病,助力《健康中国2030规划纲要》中 ‘到2030年实现整体癌症5年生存率提高15%’战略目标的达成。”

在中国,肺癌高居发病率和死亡率首位,疾病负担日益增加,其中ALK阳性晚期NSCLC患者平均年龄在52岁,正处于年富力强的黄金期,数据显示:20-40%的ALK阳性晚期非小细胞肺癌患者在初诊时就已发生脑转移,且发生率随时间延长而升高,即使经过ALK抑制剂治疗,45-70%的患者也会出现脑部进展,对患者生存带来严峻挑战。

“近期美国癌症研究学会(AACR)公布的临床研究数据表明,博瑞纳®一线治疗ALK阳性NSCLC的无进展生存期(PFS)已突破三年,表现出了前所未有的疾病无进展生存时间。”博瑞纳®中国注册研究主要研究者、广东省肺癌研究所名誉所长吴一龙教授指出:“博瑞纳®具备出色的血脑屏障穿透能力,无脑转移的患者接受其治疗能有效阻遏脑转移发生。而有脑转移的患者治疗后,颅内客观缓解率高达83.3%。这些数据得到了业界的高度关注,也为医生选择一线治疗方案提供了理论依据。”

“博瑞纳®是专为穿透血脑屏障和抑制其他ALK抑制剂导致的耐药突变而研发,为预防和延缓疾病进展提供了出色的解决方案。”博瑞纳®中国注册研究主要研究者、上海交通大学附属胸科医院陆舜教授介绍:“目前针对ALK阳性NSCLC的传统治疗中,普遍存在多点位的耐药问题,导致药物疗效下降,患者不得不中断治疗。我们一直期待突破耐药局限的新药上市,对于接受过ALK抑制剂治疗发生耐药的患者,我们发现博瑞纳®显示出了强大抗肿瘤活性和颅内活性,可以进一步抑制肿瘤生长,为患者争取更长的生存时间。”

2020年7月,博瑞纳®作为临床急需进口药品获得海南省药监局批准进口,患者在海南开始接受治疗,目前已有数位患者获益于博瑞纳®的治疗。同时,博瑞纳®被纳入“乐城全球特药险” 并与北京、山西、湖南等省市惠民保对接,通过补偿型医疗保险等形式,减轻患者治疗负担,提高药物可及性。
