灵北和大冢重磅精神病药物Rexulti获美国FDA批准用于精神分裂症的维持治疗

2016-09-27 佚名 生物谷

丹麦药企灵北(H.Lundbeck)和日本药企大冢(Otsuka)近日联合宣布,美国食品和药物管理局(FDA)已批准扩大精神病新药Rexulti(brexpiprazole)的药物标签,用于精神分裂症成人患者的维持治疗。 Rexulti是一种每日一次的口服药物,由大冢发现,由灵北和大冢联合开发,该药于2015年7月获FDA批准Rexulti:(1)作为一种辅助药物用于重度抑郁症(MDD)成人

丹麦药企灵北(H.Lundbeck)和日本药企大冢(Otsuka)近日联合宣布,美国食品和药物管理局(FDA)已批准扩大精神病新药Rexulti(brexpiprazole)的药物标签,用于精神分裂症成人患者的维持治疗。

Rexulti是一种每日一次的口服药物,由大冢发现,由灵北和大冢联合开发,该药于2015年7月获FDA批准Rexulti:(1)作为一种辅助药物用于重度抑郁症(MDD)成人患者的治疗;(2)用于精神分裂症(schizophrenia)成人患者的治疗。

去年,彭博社发布《2015年新药中的重磅炸弹》,预测了11个已经在2015年获批或可能获批的新药在2020年的销售额,Rexulti名列其中,彭博社预计该药在2020年的销售额将达到11.2亿美元。另外,Rexulti也被列入路透社在2015年初发布的《2015最值得关注的药品预测》名单,该机构预测Rexulti在2019的销售额将达到13.53亿美元。

此次FDA批准扩大Rexulti药物标签,是基于一项52周的随机退出临床研究的积极顶线数据。该研究在18-65岁的精神分裂症成人患者中开展,研究中患者接受Rexulti治疗病情稳定之后,随机分配至继续接受Rexulti(n=96)或安慰剂(n=104)治疗,主要终点是从随机治疗开始直至病情复发的时间间隔。数据显示,与安慰剂治疗组相比,Rexulti治疗组(1mg/天-4mg/天)从启动随机治疗至病情复发的时间间隔具有统计学意义的显著延长(p<0.0001,最终分析)。该研究因Rexulti具有显著的维持疗效而提前终止。在随机维持阶段,不良反应事件与短期精神分裂症临床研究一致。

据估计,在美国大约有240万精神分裂症成人患者,大约75%的患者在某些情况下会经历病情的复发及恶化。

目前,Rexulti治疗重度抑郁症(MDD)和精神分裂症的确切作用机制尚不明了,该药的疗效可能是通过5-HT1A受体和多巴胺D2受体的部分激动剂活性、血清素5-HT2A受体的拮抗剂活性联合介导。此外,Rexulti除了对这些受体表现出高亲和力(次纳摩尔,subnanomolar),针对去甲肾上腺素α1B/2C受体也表现出高亲和力。

灵北启动精神分裂症新药Lu AF35700 III期临床项目

丹麦制药商灵北(Lundbeck)近日宣布启动新型抗精神病药物Lu AF35700的III期临床项目。该项目包括2个关键III期研究,将评估2种剂量Lu AF35700(10mg,20mg)治疗难治性精神分裂症( treatment resistant schizophrenia,TRS)的疗效和安全性。主要终点是治疗的第10周阳性和阴性症状量表(P
