最新阿尔兹海默症(AD)疗法“创新声光疗法”的2期临床试验积极结果

2021年7月26日,阿尔茨海默病协会国际会议(Alzheimer’s Association International Conference, AAIC-2021)隆重开幕。该会议是世界上最大和最具影响力的致力于推进痴呆症科学研究的国际会议,汇集了世界一流的基础科学和临床研究人员、临床医师、护理研究团体,共同分享探讨预防、诊断、阿尔兹海默症和相关疾病的最新研究发现和解决方案。

阿尔茨海默病(AD)是以进展性认知障碍为核心临床表现的神经系统变性疾病,随着我国人口老龄化加剧,AD俨然成为一个迫在眉睫的问题,据2020年首都医科大学宣武医院发表于《柳叶刀·公共卫生》的一项研究统计,我国AD患者约有983万,但遗憾的是,由于AD病因复杂,因此其治疗手段则非常有限。

近年来,大量阿尔兹海默症药物临床试验纷纷折戟,直到今年6月,阿尔兹海默症才迎来18年首个新药aducanumab,但却引起巨大争议。因此,亟需开发其他疗法挽救局面。

在今年的会议上,麻省理工学院(MIT)蔡立慧教授联合创立的Cognito Therapeutics公司向我们展示了最新阿尔兹海默症(AD)疗法“创新声光疗法”的2期临床试验积极结果,值得一提的是,该创新声光疗法在今年1月获得了FDA授予的突破性医疗器械认定(Breakthrough Device Designation)。

众所周知,加速性脑萎缩与AD患者的认知功能下降和功能丧失相关,是疾病进展中死亡率和发病率的关键驱动因素,而该疗法“不用吃药”即可改善AD患者的相关症状,可使患者的脑萎缩显着减少,表现为脑容量损失下降了65%!这项研究成果既证明了治疗这种神经退行性疾病的根本性转变,又证明了该疗法对大脑神经元独特的作用机制。

据悉,这项名为“OVERTURE”的临床研究主要针对轻度至中度AD患者,在为期6个月的治疗后发现,AD患者的日常生活能力评分的下降速度减缓了84%,记忆和认知能力衰退速度降低了83%。

此外,研究指出,睡眠紊乱与AD 的发生和发展显着相关,因此改善睡眠也是 AD 患者新治疗策略的一个重要方面,而这项创新疗法恰好能减少AD患者睡眠碎片化。

Cognito Therapeutics的首席执行官Brent Vaughan表示:“我们在此次会议报告的阿尔茨海默氏症患者夜间睡眠的改善,为我们改善该疾病的机制提供了进一步的支持,这是一个重要的里程碑,未来,我们期待能够扩大阿尔茨海默病在关键研究中的临床验证。”
