About this study

Alzheimer's disease is associated with accumulation in the brain of a protein called amyloid. The purpose of this study is to test the ability of a research drug to measure amyloid in brain using positron emission tomography (PET) and a research drug called [11C]MeS-IMPY.

Read the detailed description

Alzheimer's disease (AD) is characterized pathologically by the presence of beta-amyloid plaques in brain. A substantial body of research indicates that the presence of increased beta -amyloid peptide is neurotoxic, and may initiate further pathology observed in AD including neurofibrillary tangles, synaptic loss and dysfunction, and neurodegeneration. There are multiple binding sites available on beta-amyloid plaques. Three clearly identified sites are Congo-red type, Thioflavin-T type, and FDDNP type. Radioligands currently under development using positron emission tomography (PET) for studying beta-amyloid in clinical research or drug development are based on Thioflavin-T site, such as [11C]PIB and [11C]SB-13. Though variously effective, these radioligands have one or more drawbacks with respect to measuring relative regional beta-amyloid densities. Therefore, we have recently developed [11C]MeS-IMPY as an alternative radioligand for imaging beta-amyloid, which will allow a more accurate quantification of amyloid plaques in AD brain. In the current protocol, we wish to evaluate [11C]MeS-IMPY in both healthy subjects and AD patients to determine the kinetics of brain imaging beta-amyloid plaques in AD patients.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [11C]MeS-IMPY in people with Alzheimer's Disease and Healthy, run by National Institute of Mental Health (NIMH) at 1 site in United States.

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 4 inclusion and 10 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: finished, as of the sponsor's last update on 2 Jul 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00407576, which also lists 3 linked publications.

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 2 Jul 2017.
