药品与企业信息

11C-ER176药物

其他名称：[11C] ER176

11C-ER176 sticks to parts of the brain where there is inflammation. Past studies have shown that inflammation is present in the brains of patients with Alzheimer's disease. The purpose of this study is to determine if 11C-ER176 is able to accurately measure inflammation in patients with Alzheimer's disease. 11C-ER176 will be administered at activity up to 20 millicurie (mCi) per injection.

18F-MK6240药物

其他名称：[18F-MK6240]

MK-6240 measures a protein called in the brain. MK-6240 is experimental but has been used in several human studies before and has been proven to accurately measure tau in the brain.

18F-Florbetaben药物

其他名称：[18F] Florbetaben

Florbetaben has been approved by the FDA to help diagnose Alzheimer's disease. florbetaben measures amyloid in the brain.

Lumbar Puncture治疗操作

其他名称：Spinal Tap

Inflammation can also be measured by looking at certain proteins in the spinal fluid. In order to measure these proteins in the spinal fluid, the investigators will perform a lumbar puncture (spinal tap).

研究简介（原文）

The purpose of this study is to determine how inflammation is related to other changes in the brain that occur during the progression of Alzheimer's disease. The investigators are also studying how inflammation is related to the symptoms that first occur in patients with Alzheimer's disease (AD). For this reason, the investigators are asking people with different versions of Alzheimer's disease and/or other related dementias to participate. This includes patients with: * Mild Cognitive Impairment * Posterior cortical atrophy - a version of Alzheimer's disease with vision difficulties * Logopenic variant primary progressive aphasia - a version of Alzheimer's disease with language difficulties * Amnestic Alzheimer's disease - a "typical" version of Alzheimer's disease with memory difficulties * The investigators are also enrolling older adults with normal visual, language, and memory function.

这项试验目前在中国大陆没有研究中心

这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
