About this study
Official title: Multimodal Biomarkers for Diagnosis and Prognosis in Vascular Cognitive Impairment
We will try to
- establish the correlation of plasma Aβ40 and Aβ42 level, ApoE genotype, MRI imaging markers in the diagnosis and prognosis of VCI patients
- understand more on the pathophysiology of VCI.
Read the detailed description
Background and objectives Owing to the aging problem, cognitive impairment has been a worldwide health issue. Vascular cognitive impairment (VCI) and Alzheimer's disease (AD) are the two most common causes. It has been reported that VCI and AD share many common risk factors. MRI is essential in assessing the extent, location and type of vascular lesions. Amyloid PET has been used in detecting cerebral amyloid burden non-invasively since 2004. There are only small number of studies using amyloid PET in VCI and the results are still controversial. In the current proposal, we will investigate
- the correlation of clinical risk factors, ApoE genotype, various MRI markers, and amyloid PET expression
- assess the influence of ApoE genotype on different biomarkers, including MRI markers, amyloid retention, and plasma Aβ40 and Aβ42 levels
- the potential of amyloid PET as a prognostic factor for VCI patients.
Materials and methods This study will be conducted in National Taiwan University Hospital and Bei-Hu Branch Hospital. Sixty clinical diagnosed VCI, 30 AD patients and 30 normal subjects will be enrolled in this 3-year prospective study. We will collect vascular risk factors, neuropsychological tests, 10 cc venous blood for plasma Aβ40, Aβ42, total tau and phosphorylated level measurement by IMR assay, ApoE genotype, brain MRI, and amyloid PET of each patient and control subject. All the data will be analyzed together.
Expected Results We will try to
- establish the correlation of plasma Aβ40 and Aβ42 level, ApoE genotype, MRI imaging markers in the diagnosis and prognosis of VCI patients
- understand more on the pathophysiology of VCI.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing amyloid PET in people with Vascular Cognitive Impairment and Alzheimer Disease, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 18 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PET imaging (time frame: in 3 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2020.
