Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 65 years and older
  • All sexes
  • No healthy volunteers
  • Older adult

Who may be able to join

  • Cognitive decline and/or personality change is present, as observable by physician and/or close contact(s) of the patient; or in the absence of this, the patient provides a clear history of decline that the patient's physician deems to be reliable.
  • If history or neurologic exam reveals findings suspicious for stroke, tumor, bleed, ictal activity, or hydrocephalus, then CT/MRI and appropriate neurological or neurosurgical consultation must have been obtained.
  • Standard history, physical, and laboratory screen have been performed to identify possible presence of depression, substance abuse, malnourishment, medication effects and interactions, cardiopulmonary compromise, electrolyte/calcium imbalance, anemia, hypoxemia, infection, thyroid dysfunction, renal dysfunction, hepatic dysfunction, or glucose dysregulation.
  • Any positive findings revealed in 2) or 3) above have been appropriately treated, wherever possible, but cognitive/behavioral deficit persists post-therapy.

Who cannot join

  • Subjects under age 65 will not be recruited, in order to enhance the relevance of the project by focusing on the group of Medicare beneficiaries in whom serious concerns about early signs and symptoms of senile onset dementia are most typically emerging.
  • Cognitive dysfunction has impaired subject's ability to perform activities of daily living.
  • Present or past history of thyroid disease.
  • Claustrophobia or metal in body or other condition that would preclude PET or MRI from being acquired.
  • Visual, auditory or motor deficits that would preclude accurate neuropsychological testing.
  • AD-specific pharmacotherapy already initiated.

About this study

Official title: Early and Long-Term Health Outcomes of Molecular Cerebral Imaging in Incipient Dementia (MCI-ID) II

A substantial portion of people covered by Medicare will develop Alzheimer's disease and other forms of dementia that together devastate the lives of millions of people in the United States, and cost us a total of over $200 billion every year. Getting a brain scan with a PET scanner to look for abnormal brain metabolism patterns is recognized as "reasonable and necessary" for some patients with "a recently established diagnosis of dementia" (Centers for Medicare and Medicaid Services (CMS), Decision Memo CAG-00088R), but the evidence is considered less clear for patients having less severe cognitive problems, and/or for patients getting a brain scan with a PET scanner to look for abnormal proteins in the brain (CMS Decision Memo CAG-00431N). This project employs a scientifically rigorous design (prospective, multi-centered, randomized controlled trial) to determine whether such PET scanning can help distinguish more accurately than is being done in current clinical practice those patients with early molecular changes in their brains who will benefit from Alzheimer related treatments from those patients who will not, as proven by measuring to what extent the PET scans actually lead to earlier appropriate therapy, and in fact result in improved outcomes for Medicare beneficiaries and for the health care system in which they obtain care.

Read the detailed description

The overarching objective of this project is to test whether diagnostic assessments informed by data on molecular cerebral changes can lead to improved health outcomes of an epidemiologically major segment of the geriatric patient population - people experiencing changes in their cognitive skills relative to their prior level of cerebral functioning. In the present proposal, we specifically aim to measure how knowledge of molecular cerebral information 1) influences the therapeutic management of patients being evaluated for symptoms of cognitive decline, and 2) impacts upon long-term health outcomes, particularly for patients having findings on positron emission tomography (PET) scans consistent with presence of Alzheimer's disease (AD)- like changes in their brains. Patients suffering from documentable decline of cognitive function will undergo baseline neuropsychologic testing, and neuroimaging with MRI and PET. Reports of PET scans will be sealed at the time of interpretation, and then randomized with respect to whether they are released to the patients' managing physicians at the time of interpretation, or two years after the time that scanning is performed. All treatment decisions will be made by the managing physicians and their patients. Cognitive abilities, functional status, and other clinical and social history parameters will be assessed every six months. Our central hypothesis is that among the group of patients whose PET scan results are conveyed to their physicians at the time of scanning, cognitive and functional abilities will be maintained at a higher level during the two years following PET. Beyond addressing the specific aims noted above and further described below, a valuable feature of this project will be the collection of a rich source of data that can be used to address many questions beyond its major focus (e.g., diagnostic value of volumetric MRI data used instead of, or in conjunction with, PET data in the Medicare beneficiary population; incremental value of applying statistically parameterizing and/or quantifying software tools to PET data). The protocol has been designed to conform to all standards specified by the Centers for Medicare and Medicaid Services (CMS) for Coverage with Evidence Development (CED), generally, and with all requirements for a CED study responsive to CMS Decision Memo CAG-00431N, specifically.

What is being measured

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

  1. Rate of change from baseline in neuropsychological (cognitive,functional) test results

    Study participants will undergo neuropsychological testing at baseline and every six months for two years.

    Measured: baseline, 6 months, 12 months, 18 months, 24 months

  2. Utilization of healthcare resources

    Measured: over 2 years

  3. FDG-PET and amyloid imaging results, compared with working diagnoses made before and after time of imaging

    Study participants will undergo FDG-PET and amyloid imaging. Working diagnoses made before and after the imaging is performed will be compared.

    Measured: baseline and up to 2 years

  4. Rates of prescription of AD-specific therapies

    Comparisons between the rate of prescription for AD-specific therapies and release type (either immediate or delayed release) will be made.

    Measured: baseline, 6 months, 12 months, 18 months, 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Amyloid imaging and FDG-PET in people with Mild Cognitive Impairment, run by University of California, Los Angeles.

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 6 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: withdrawn, as of the sponsor's last update on 15 Oct 2018. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was withdrawn before enrolling participants, so there are no results.

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 from baseline in neuropsychological (cognitive,functional) test results (time frame: baseline, 6 months, 12 months, 18 months, 24 months). The study lists 4 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 15 Oct 2018.
