概括
在7年内,Ozanimod在复发性多发性硬化症中持续减少大脑缩. 大脑体积的保存与更好的认知功能和更慢的残疾进展有关.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 临床试验 临床试验
背景情况:
- 在3期试验中,与干扰素β-1a (IFN) 相比,ozanimod在降低脑缩和改善复发性多发性硬化症 (RMS) 的认知处理速度方面表现出有效性.
研究的目的:
- 评估长期的大脑体积变化及其与临床和认知结果的关联,在RMS参与者中对ozanimod进行开放式扩展研究 (DAYBREAK).
- 评估ozanimod在长时间内保持大脑体积方面的持续有效性.
主要方法:
- 完成第三阶段试验的参与者继续在DAYBREAK开放式扩展中接受ozanimod (0.92毫克) 治疗.
- 每年对整个大脑体积 (WBV),乳头体积 (TV) 和皮质灰质体积 (CGMV) 进行评估.
主要成果:
- 持续使用ozanimod治疗显示持续,低率的WBV损失长达60个月 (年化变化: -0.27%在RADIANCE, -0.35%在SUNBEAM).
- 与从IFN转换的参与者相比,持续服用ozanimod的参与者经历的WBV减少较小.
- 较大的基线大脑体积与更好的符号数字模式测试分数和减少3个月确认残疾进展 (CDP) 相关联.
- 年化电视缩率为1.0%或以下与较低的3个月CDP发病率有关.
结论:
- 在RMS中,ozanimod在降低脑缩率方面提供了持续的有效性,长达7年.
- 使用ozanimod保持大脑体积与提高认知处理速度和减缓身体残疾进展有关.

Alzheimer's Disease: Overview
669
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Alzheimer's Disease: Treatment
262
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
