What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cross-sectional [18F]PI-2620 Imaging Results

    Compare Standard uptake value ratio (SUVR) and distribution of [18F]PI-2620 in subjects with tauopathies and cognitively healthy individuals.

    Measured: 60-90 minutes post injection

  2. .Assess the rate of change of tau deposition as measured by [18F]PI-2620 uptake (SUVR) over time

    Compare Standard uptake value ratio (SUVR) and distribution of [18F]PI-2620 in subjects with tauopathies and cognitively healthy individuals.

    Measured: 60-90 minutes post injection

Secondary outcomes (2)
  1. Correlation between standard uptake value ratio (SUVR) of [18F]PI-2620 positron emission computed tomography and neuropsychiatric test scores

    We will evaluate correlation between standard uptake value ratio (SUVR) [18F]PI-2620 positron emission computed tomography and scores of neuropsychiatric test

    Measured: 60-90 minutes post injection

  2. Correlation between standard uptake value ratio (SUVR) of [18F]PI-2620 positron emission computed tomography and indices of structural MRI

    We will evaluate correlation between standard uptake value ratio (SUVR) [18F]PI-2620 positron emission computed tomography and indices of structural MRI including cortical thickness, hippocampal atrophy.

    Measured: 60-90 minutes post injection

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing [18F]PI-2620 in people with Healthy Volunteer and Alzheimer Disease, run by Asan Medical Center at 1 site in South Korea.

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 13 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 14 Dec 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 South Korea. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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.

What does the primary outcome measure?

Cross-sectional [18F]PI-2620 Imaging Results (time frame: 60-90 minutes post injection). The study lists 2 primary outcomes in all. 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 Dec 2020.
