Study for Early-Onset Alzheimer's Disease
(LEADS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to better understand early-onset Alzheimer's disease by observing its progression over time. Participants will undergo various assessments, including cognitive tests and brain scans, to gather data on their condition. The study includes three groups: those with early-onset Alzheimer's, those with early-onset cognitive issues not related to Alzheimer's, and those with normal cognitive function. Individuals diagnosed with early-onset memory or thinking problems, or those who are cognitively normal and between 40-64 years old, might be a good fit. This research will not provide any treatment but will help inform future therapies. As an unphased study, this trial offers a unique opportunity to contribute to groundbreaking research that could shape future treatments for early-onset Alzheimer's.
Do I need to stop my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. However, investigational agents are not allowed 30 days before joining the study, and certain medications may be restricted for optional procedures. It's best to discuss your specific medications with the study team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that Florbetaben and Flortaucipir, both used in PET scans for Alzheimer's research, are generally safe. Florbetaben detects amyloid plaques in the brain. Some individuals have reported mild side effects like headaches or dizziness, but it is usually well-tolerated. Flortaucipir scans identify tau protein build-up, another Alzheimer's indicator. Studies have demonstrated its accuracy in identifying patients with high tau levels, and no serious side effects were commonly reported.
Both have undergone testing in various studies and are considered safe enough for trials. However, like any medical procedure, a small risk of side effects exists. Prospective participants should discuss any concerns with the study team.12345Why are researchers excited about this trial?
Researchers are excited about the Longitudinal Early-onset Alzheimer's Disease Study Protocol because it aims to deepen our understanding of how Alzheimer's develops in its early stages. Unlike current treatments that primarily focus on managing symptoms, this study uses advanced imaging techniques like florbetaben and flortaucipir PET scans to track amyloid and tau protein buildup in the brain. This approach could lead to earlier and more accurate diagnosis, potentially opening the door to better-targeted treatments in the future. By studying different groups, including those with and without Alzheimer's, the trial could uncover crucial differences in disease progression and cognitive function, paving the way for breakthroughs in early intervention strategies.
What evidence suggests that this trial's treatments could be effective for early onset cognitive impairment?
In this trial, participants will undergo various PET scans to study Alzheimer's disease and related conditions. Research has shown that florbetaben, used in some trial arms, aids in understanding Alzheimer's by predicting progression through the detection of amyloid plaques, sticky protein clumps linked to the disease. Studies indicate that florbetaben PET scans can differentiate early-onset Alzheimer's from other conditions by identifying these amyloid markers. Meanwhile, flortaucipir, used in other trial arms, detects tau protein tangles, another sign of Alzheimer's. Flortaucipir PET scans have demonstrated high accuracy in identifying Alzheimer's patterns, with both sensitivity and specificity around 90%. These scans provide valuable insights into how Alzheimer's develops and progresses, aiding in early diagnosis and understanding.36789

Treatment groups
Experimental Treatment
* Diagnosis of NIA-AA criteria of MCI due to AD or probable AD dementia * Amyloid negative status (florbetaben PET scan with no evidence of elevated amyloid as determined by a central read) * CDR score ≤ 1.0 * flortaucipir (18F-AV-1451) PET scanning
* Diagnosis of NIA-AA criteria of MCI due to AD or probable AD dementia * Amyloid positive status (florbetaben PET scan with evidence of elevated amyloid as determined by a central read) * CDR score ≤ 1.0 * flortaucipir (18F-AV-1451) PET scanning
* Meets criteria for cognitively normal, based on an absence of significant impairment in cognitive functions and activities of daily living * Mini-Mental State Exam score between 26-30 * CDR score = 0 * flortaucipir (18F-AV-1451) PET scanning
