智通财经APP获悉,同源康医药(股票代码:02410)今日宣布,已于近日向国家药品监督管理局药品审评中心(CDE)提交了其在研1类新药甲磺酸艾多替尼片(TY-9591)的Pre-NDA申请,该药有望成为全球首款针对非小细胞肺癌(NSCLC)脑转移患者的第三代EGFR -TKI。
本次Pre-NDA申请是基于TYKM1601202研究(ESAONA)的卓越结果。该研究是一项前瞻性、多中心、随机、活性对照的关键注册性研究,旨在评估甲磺酸艾多替尼片对比奥希替尼一线治疗NSCLC脑转移受试者的有效性和安全性。本研究由中国医学科学院肿瘤医院石远凯教授牵头,由山东省肿瘤医院、湖南省肿瘤医院等共计53家中心参研。该研究详情,请浏览clinicaltrial.gov,NCT 05948813。
截止本次递交,研究共入组了224例EGFR敏感突变的NSCLC脑转移患者。研究结果显示,甲磺酸艾多替尼片对比奥希替尼的主要研究终点(IRC评估的颅内客观缓解率)达到了显著优效结果。同时,甲磺酸艾多替尼片显示出良好的安全耐受性,未发现新的安全性风险。详细的研究数据将于国际学术大会或学术期刊上发布。
中国国家药品监督管理局(NMPA)已将艾多替尼纳入附条件上市品种,用于治疗EGFR敏感突变NSCLC脑转移患者。
肺癌是脑转移发生最常见的恶性肿瘤,其脑转移发生率远高于其他肿瘤。晚期NSCLC初治患者的脑转移发生率达25%-44%,随着生存期的延长,脑转移累积发生率逐年增高。携带EGFR突变、ALK重排等驱动基因阳性的NSCLC患者,相比驱动基因阴性患者,表现出更高的脑转移风险和更早的发病时间。EGFR突变型NSCLC患者的3年累积脑转移率可达29.4%-60.3%。NSCLC脑转移患者经治后的中位生存期短,仅7-12个月。目前全球尚无针对NSCLC脑转移适应症的第三代EGFR-TKIs获批上市,甲磺酸艾多替尼有望满足该类患者人群亟待解决的的临床治疗需求。
