Trial summary

Reliable diagnosis of Alzheimer's Disease (AD) at the predementia stage is currently considered to be a priority for research, as disease modifying therapies are being evaluated. Many studies focus on the functional and morphological assessment of the hippocampal formation. Read more about this study

About this study

Official title: Can the Assessment of the Subhippocampal Region Contribute to the Detection of Early Diagnosis of Alzheimer's Disease?

Reliable diagnosis of Alzheimer's Disease (AD) at the predementia stage is currently considered to be a priority for research, as disease modifying therapies are being evaluated. Many studies focus on the functional and morphological assessment of the hippocampal formation. However, neurofibrillary tangles, associated with cognitive deficits, initially affect the anterior subhippocampal cortex (transentorhinal, entorhinal and perirhinal cortex) before reaching the hippocampus. Studies from our group have tried to investigate if the assessment of subhippocampal regions using cognitive tools and neuroimaging techniques could contribute to the diagnosis of AD at a very early stage.

In a previous project, the investigators included 40 patients with single domain amnestic MCI (Mild Cognitive Impairment), known to be at high risk for AD and demonstrated that aMCI patients with a profile of subhippocampal dysfunction (impaired performance on a visual recognition memory task) display other clinical as well as imaging profiles of patients with early AD using MRI and SPECT. Longitudinal follow-up data in these patients is currently under way. Preliminary data indicates that evaluating the subhippocampal region using visual recognition tasks is highly predictive of AD over 6 years.

The aim of this project is to obtain additional diagnostic data using a PET amyloid tracer (Florbetapir F18 AV45 F18), an in-vivo marker of one of the neuropathological lesions that define AD, of in order to enhance diagnostic accuracy AD in these patients. This approach will validate the hypothesis as to whether the assessment of subhippocampal dysfunction can contribute to the early diagnosis of AD.

Questions about this trial

What is this clinical trial studying?

A study testing PET amyloid tracer (Florbetapir F18 AV45 F18 in people with Alzheimer's Disease, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

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 12 inclusion and 2 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 14 Apr 2017. 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 France. 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.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the assessment of subhippocampal dysfunction (time frame: 24month). 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 14 Apr 2017.
