Who cannot join

  • Diagnosis of mild cognitive impairment or dementia
  • History of significant brain injury or other known neurologic disease or insult, resulting in lasting cognitive sequelae that would confound the assessment and staging of potential neurodegenerative disease (e.g., Huntington's disease, Parkinson's disease, Parkinsonism due to multiple system atrophy (MSA), progressive supranuclear palsy (PSP), Shy Drager Syndrome (SDS) or other neuro-degenerative dementias, encephalitis or other brain infection, epilepsy or stroke with lasting impairment to cognitive function).
  • Current serious or unstable systemic illness or organ failure that, in the PI's judgement, would make it difficult to participate in the study (e.g., such as terminal cancer, cardiovascular, hepatic, renal, gastroenterological, respiratory, endocrinologic, neurologic, psychiatric, immunologic, or hematologic disease or other conditions ). History of cancer is acceptable with at least one year in remission with a good prognosis.
  • Individuals with clinically significant depression, bipolar disorder, anxiety, or suicidal ideations within the past year as defined by the most current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM).
  • A history of schizophrenia as defined by the most current version of the DSM.

Study groups in NCT05457998
Study groupRoleWhat they receive
Main study population: Cognitively unimpaired individuals (50-80 y)Participants will be enrolled based on a predetermined ratio of Alzheimer's Disease plasma and PET biomarker risk levels (e.g., as P-tau217 and amyloid PET). FOLLOW-UP FOR 4 YEARS: Cognitive testing, blood draws and retinal imaging will be conducted at baseline and 12 months. Cognitive testing and blood draws will be conducted at 24 months and 36 months. MRI and amyloid PET scans will be performed at screening/baseline and 24 months. An additional amyloid PET scan will be performed at 48 months.
Receives: Diagnostic Test: Flutemetamol F18 Injection
Sub-group 1: Optional Tau PET imaging sub-studyAn optional tau PET imaging sub-study will be conducted in 70 subjects from the main study population who elect to participate. If enrolled in the optional tau PET imaging sub-study, participants will have three tau PET scans with [18F]RO-948: at baseline, 24 months, and 48 months.
Receives: Diagnostic Test: [18F]-RO6958948 Injection
Sub-group 2: Optional Tau PET tracer comparison sub-studyAn optional tau PET tracer comparison sub-study will be conducted in 30 subjects from the main study population who elect to participate. Tau PET scans with 2 tracers ([18F]RO-948 and [18F]MK-6240) will be performed at baseline and 24 months. An additional Tau PET scan with [18F]RO-948 will be performed at 48 months.
Receives: Diagnostic Test: [18F]-RO6958948 Injection; Diagnostic Test: [18F]-MK-6240 Injection

What is being measured

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

  1. Rate of change in plasma biomarkers

    Validate and assess longitudinal changes from baseline in plasma amyloid, phosphorylated tau (p-tau) and other fluid biomarkers (e.g., neurofilament light).

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

  2. Rate of change in cerebral amyloid pathology

    Longitudinal assessment of cerebral amyloidosis based on amyloid PET imaging.

    Measured: Time Frame: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 5 years after baseline.

  3. Rate of change in Tau PET measures

    Longitudinal assessment of cerebral tau accumulation based on tau PET imaging.

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

Secondary outcomes (4)
  1. Rate of cognitive decline as measured by traditional cognitive and behavioral assessments

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

  2. Rate of cognitive decline as measured by digital cognitive assessments

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

  3. Rate of change in retinal imaging metrics

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

  4. Rate of change in psychological wellness as measured by the Geriatric Depression Scale

    Measured: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer Disease and Mild Cognitive Impairment, run by Butler Hospital 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 8 inclusion and 9 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: enrolling by invitation, as of the sponsor's last update on 17 Dec 2024. 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Rate of change in plasma biomarkers (time frame: Time zero equals the baseline visit. All subjects will subsequently attend follow-up visits every year for 4 years after baseline.). The study lists 3 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 17 Dec 2024.
