葛兰素史克(GlaxoSmithKline)的Benlysta(贝利木单抗)长期以来一直是作为系统性红斑狼疮治疗领域唯一生物制剂。但是随着竞争者的涌入,GSK希望将Benlysta带入另一个尚未尝试的适应症--狼疮性肾炎,可以帮助该药物达到重磅炸弹的门槛。

葛兰素史克(GlaxoSmithKline)的Benlysta(贝利木单抗)长期以来一直是作为系统性红斑狼疮治疗领域唯一的生物制剂。但是随着竞争者的涌入,GSK希望将Benlysta带入另一个尚未尝试的适应症--狼疮性肾炎,可以帮助该药物达到重磅炸弹的门槛。

在一项名为Bliss-LN的3期研究中,Benlysta组中43%的狼疮性肾炎患者达到了主要终点,即肾脏反应(一种肾功能的指标),而对照组中这一比例为32%。Benlysta组的患者在次要终点(包括死亡时间或肾脏相关的并发症)中也显示出明显更高的反应。

GSK美国特种制药业务高级副总裁Sheri Mullen表示,这些数据可能使Benlysta成为首个被批准用于治疗狼疮肾炎的药物,从而扩大了该产品的患者群体,并将于2020年上半年提交申请给FDA

"我们的希望是,这些数据能使医生进一步放心,Benlysta对这些患者具有很强的疗效。" Mullen说。

Benlysta是唯一批准用于狼疮的生物制剂,在2019年的前9个月中,Benlysta的全球销售额为5.81亿美元,比去年同期增长了32%。

GSK表示,增加适应症可以进一步提高该药的销量,每年在328000名美国重度狼疮患者中约有60%患有狼疮性肾炎。

Benlysta是首个B淋巴细胞刺激因子(B lymphocyte stimulator,BLyS)特异性抑制剂,能阻断可溶性BLyS(一种B细胞生存因子)与B细胞上的BLyS受体的结合,抑制B细胞的生存、减少B细胞向制造免疫球蛋白的浆细胞的分化。Benlysta能够减少导致狼疮患者病情加重的异常B淋巴细胞的数量,这些异常的B淋巴细胞会导致免疫系统产生细胞错误攻击血管和自身其他健康组织,从而引起狼疮和其他免疫系统疾病。
