概括
对于阿尔茨海默病免疫疗法 (如阿杜卡努马布,莱卡努马布和多纳努马布) 的资格标准有很大差异,影响患者数量. 现实数据显示,只有很少一部分阿尔茨海默病患者有资格接受这些粉样β向治疗.
科学领域:
- 神经学 神经学
- 免疫治疗是一种免疫疗法.
- 临床试验 临床试验
背景情况:
- 化β (Aβ) 向免疫疗法代表了治疗早期症状性阿尔茨海默病 (AD) 的重大进展.
- 准确确定患者的资格对于临床实践,资源配置和AD治疗成本管理至关重要.
研究的目的:
- 通过临床试验和适当使用建议 (AUR) 标准,估计有资格接受Aβ向抗体 (aducanumab,lecanemab,donanemab) 的患者数量.
- 在专业中心的真实样本中分析患者的资格,利用尸检报告来确认病理.
主要方法:
- 使用国家阿尔茨海默氏症协调中心 (NACC) 数据集 (N=3,343) 与可用的神经病理报告进行的回顾性,描述性研究.
- 从第三阶段临床试验和AUR中应用了包含/排除标准,以确定特定的Aβ向免疫疗法的合格参与者.
主要成果:
- 在887名患有无记忆性AD综合征的潜在候选人中,符合条件因抗体而异:aducanumab (9%),lecanemab (31%),donanemab (19%) 根据试验标准.
- 根据AUR标准,阿杜卡努马布的27%,莱卡内马布的30%.
- 符合条件的群体显示部分重叠,并共同病理普遍存在.
结论:
- 针对Aβ向免疫疗法的患者资格在抗体和标准集之间有所不同,这表明不同的患者群体.
- 由于NACC-UDS数据集对某些标准的数据限制,实际符合条件的患者数量可能低于估计数量.

Alzheimer's Disease: Treatment
147
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...

Alzheimer's Disease: Overview
422
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...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
