About this study

Official title: An Open-label Study to Assess Brain Uptake and Safety of Flutemetamol F 18 Injection in Japanese Subjects With Probable Alzheimer's Disease, Subjects With Amnestic Mild Cognitive Impairment and Healthy Volunteers

This was a Phase 2, multicenter study to assess the extent and patterns of [18F] flutemetamol uptake in the brains of 3 groups of Japanese subjects: healthy volunteers (HV), amnestic mild cognitive impairment (aMCI), and probable Alzheimer's disease (pAD), and to assess the reproducibility of brain uptake and of image interpretation. Subjects underwent open-label intravenous (i.v.) administration of Flutemetamol F 18 Injection and Positron emission tomography (PET) imaging of the brain. Blinded visual image reads were performed by 10 independent board-certified readers (5 Japanese and 5 non-Japanese) with nuclear medicine image interpretation experience. The blinded visual assessments were compared with the subject's clinical diagnoses, and the agreement between the image interpretations made by the 2 groups of readers (Japanese and non-Japanese) was determined.

This was a Phase 2, multicenter study to assess the extent and patterns of [18F] flutemetamol uptake in the brains of 3 groups of Japanese subjects: HV, aMCI, and pAD, and to assess the reproducibility of brain uptake and of image interpretation. The 3 comparison groups (HV, aMCI, and pAD) were defined by the subjects' main clinical diagnoses at study entry. Subjects underwent diagnostic quality anatomic brain magnetic resonance imaging (MRI), followed by open-label intravenous (i.v) administration of Flutemetamol F 18 Injection and PET imaging of the brain. Blinded visual image reads were performed by 10 independent board-certified readers (5 Japanese and 5 non-Japanese) with nuclear medicine image interpretation experience. The blinded visual assessments were compared with the subject's clinical diagnoses, and the agreement between the image interpretations made by the 2 groups of readers (Japanese and non-Japanese) was determined. Blinded visual assessments were also compared to quantitative image assessments (standardized uptake value ratio [SUVRs]). Inter-reader and intra-reader agreement was also assessed. Test-retest variability was evaluated following a second administration of Flutemetamol F 18 Injection given to a subset (N=5) of pAD subjects between 1 and 4 weeks after their first administration of Flutemetamol F 18 Injection.

What is being measured

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

  1. Blinded Visual Assessment of Positron Emission Tomography (PET) Imaging and Clinical Diagnosis by Non-Japanese Readers

    The performance of Flutemetanol F 18 injection in participants was determined by evaluation of the level of association between the blinded visual assessment of a participant's brain image and the participant's clinical diagnosis by 5 non-Japanese readers, who classified each participant's images as either normal or abnormal (raised) Flutemetanol F 18 uptake.

    Measured: Up to 90 minutes after investigational medicinal product (IMP) administration

  2. Blinded Visual Assessment of Positron Emission Tomography (PET) Imaging and Clinical Diagnosis by Japanese Readers

    The performance of Flutemetanol F 18 injection in participants was determined by evaluation of the level of association between the blinded visual assessment of a participant's brain image and the participant's clinical diagnosis by 5 Japanese readers, who classified each participant's images as either normal or abnormal (raised) Flutemetanol F 18 uptake.

    Measured: Up to 90 minutes after IMP administration

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing [18F] Flutemetamol in people with Mild Cognitive Impairment and Alzheimer's Disease, run by GE Healthcare.

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 25 inclusion and 14 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 5 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Jun 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Blinded Visual Assessment of Positron Emission Tomography (PET) Imaging and Clinical Diagnosis by Non-Japanese Readers (time frame: Up to 90 minutes after investigational medicinal product (IMP) administration). 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?

On the ClinicalTrials.gov record for NCT02813070, which also lists 1 linked publication.

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 5 Jun 2017.
