勃林格殷格翰 BI409306 阿尔茨海默症 2 期试验失败

2018-02-12 佚名 生物探索

2 月 9 日,德国勃林格殷格翰(BI)公司表示,公司候选药物 BI409306 用于阿尔茨海默症治疗的 2 期临床研究未能达到疗效终点,公司将不会继续进行 BI409306 用于阿尔茨海默症的继续开发。但公司认为,该药物对精神分裂症还有治疗希望,该公司将把精力集中在进行中的精神分裂症临床试验中。

2 月 9 日,德国勃林格殷格翰(BI)公司表示,公司候选药物 BI409306 用于阿尔茨海默症治疗的 2 期临床研究未能达到疗效终点,公司将不会继续进行 BI409306 用于阿尔茨海默症的继续开发。但公司认为,该药物对精神分裂症还有治疗希望,该公司将把精力集中在进行中的精神分裂症临床试验中。

BI 409306 是一款 PDE9 抑制剂,在两项研究中,BI 公司表示 BI409306 在认知方面没有表现出优于安慰剂的能力。

这些阿尔茨海默症治疗试验属于广泛的临床试验项目的一部分,这些临床项目旨在探索针对特定 (谷氨酸) 脑回路功能障碍的化合物作为治疗精神疾病特殊症状的潜在新疗法的有效性。因此,在研化合物 BI 409306 在精神分裂症和阿尔茨海默症相关的认知障碍和记忆障碍的患者中均进行了临床研究。下一步的研究将集中在精神分裂症治疗的两项研究上,目的是防止疾病复发并预防第一次精神分裂症的发生。

BI 将会继续进行老年痴呆疾病的探索及尝试,公司已计划将另一款化合物 GlyT1 抑制剂 BI425809 推进至临床 2 期研究,用于一系列中枢神经系统适应症(包括阿尔茨海默症)的治疗。

BI 中枢神经系统及免疫学治疗领域负责人 Jan Poth 博士表示:“对于任何能为老年痴呆症(像是阿尔茨海默症)这种疾病提供解决方案的研究,人们都会抱有很大的期望。科学研究的意义在于:即使失败是常有事件,但是所获得的临床试验结果仍会增加我们对大脑功能的理解,并有助于未来在这个领域做出进展。”

在对完整的试验数据进行全面审查之后,BI 公司打算在今年 7 月份举行的阿尔茨海默病协会国际会议(AAIC)上提交全部结果。

痴呆症是中枢神经系统最严重的疾病之一。2017 年,患有某种形式痴呆症的人数为 5000 万。这个数字几乎每 20 年就会翻一番,到 2030 年将达到 7500 万,到 2050 年达到 1.31 亿。BI 公司是欧洲“We won't rest,我们不会休息”倡议的一部分,该倡议旨在为痴呆、精神分裂症和其他疾病开发持久的疗法。
