赛诺菲计划重新提交单抗药Lemtrada sBLA

2014-04-08 tomato 生物谷

赛诺菲(Sanofi)及旗下健赞(Genzyme)4月7日宣布,经过与FDA之间富有建设性的讨论,计划于第二季度重新向FDA提交单抗药物Lemtrada(alemtuzumab,阿伦单抗)的补充生物制品许可申请(sBLA),寻求批准该药用于复发型多发性硬化症的治疗。此次sBLA的提交,将提供对FDA于2013年12月27日完整回应函(CRL)中所指出问题的回复。 去年12月,FDA审查后发现,L

赛诺菲(Sanofi)及旗下健赞(Genzyme)4月7日宣布,经过与FDA之间富有建设性的讨论,计划于第二季度重新向FDA提交单抗药物Lemtrada(alemtuzumab,阿伦单抗)的补充生物制品许可申请(sBLA),寻求批准该药用于复发型多发性硬化症的治疗。此次sBLA的提交,将提供对FDA于2013年12月27日完整回应函(CRL)中所指出问题的回复。

去年12月,FDA审查后发现,Lemtrada可能会导致系列自身免疫性疾病并潜在引发甲状腺癌、皮肤癌、乳腺癌,因此对该药的安全性问题表达了严重关注,并认为赛诺菲需要进一步补充III期临床数据,以证明该药的安全性及疗效。而FDA顾问委员会则认为,Lemtrada的安全性问题,并不妨碍该药的批准,但对相关临床研究的质量表达了担忧。

Lemtrada是一种单克隆抗体,靶向于CD52,这是一种位于T细胞及B细胞上的蛋白。Lemtrada被认为能够选择性消耗T细胞和B细胞,同时保留免疫系统中的其他抗感染成分,通过抗炎作用,有助于再次平衡免疫系统。

Lemtrada已于2013年9月获欧盟批准,用于活动性复发缓解型多发性硬化症(RRMS)成人患者的治疗。如果获FDA批准,Lemtrada将与百健艾迪(Biogen Idec)的Tysabri展开激烈竞争,该药是市面上最有效的多发性硬化症(MS)治疗药物,但可能引发一种潜在致死的脑部感染,即进行性多灶性白质脑病(PML)。这种风险,已将Tysabri的使用限制至经其他MS药物治疗失败的患者群体,若Lemtrada获批,也可能被限制至这一患者群体。根据汤姆森路透数位分析师预测,若Lemtrada获FDA获批,预计截止2018年的销售峰值仅为7.52亿美元。
