PET Imaging Agent [18F]AZD4694 in Probable Alzheimer's Disease

PET Imaging Agent [18F]AZD4694 in Probable Alzheimer's Disease

Overall Status: 
Active, not recruiting
Brief Description: 

This Phase II trial will assess the safety and efficacy of the radioactive imaging agent [18F]AZD4694 used in positron emission tomography (PET). The study will compare the agent's ability to detect beta-amyloid plaques in the brains of people with probable Alzheimer's disease compared with healthy volunteers. The agent is given as an intravenous injection.

Patient Qualifications: 
Min AgeMax AgeGenderHealthy Volunteers
18 Years
85 Years
Accepts Healthy Volunteers
Inclusion Criteria: 

    All Participants

    • Adequate general health and seeing, hearing, and communication capabilities to enable compliance with study procedures
    • Modified Hachinski score of 4 or less
    • Informed consent signed and dated by the participant or, for probable Alzheimer's participants, a legally authorized representative

    Healthy Volunteers Only

    • Between the ages of 18 and 40 years or 55 and 85 years
    • If female does not have childbearing potential, must be confirmed by postmenopausal status, surgical sterilization, or hysterectomy
    • If female has childbearing potential, must demonstrate negative serum beta-HCG level and negative urine pregnancy test and agree to use two forms of birth control
    • No evidence of cognitive impairment
    • MRI brain scan that has been judged as "normal (age-appropriate)" supporting the lack of cerebrovascular disease

    Probable Alzheimer's Disease Participants Only

    • 55 years old or older
    • Females must be without childbearing potential
    • Diagnosis of dementia of Alzheimer's type
    • No diagnosis of Lewy body disease (DLBD), vascular dementia, or frontotemporal dementia
    • Mini Mental State Examination score of between 16 and 23; Clinical Dementia Rating score of 1 to 2; Cornell Scale for Depression in Dementia score of less than or equal to 18
    • MRI brain scan findings that do not indicate stroke and/or cerebrovascular disease
    • Caregiver who is willing to attend study visits and perform psychometric tests requiring the presence of a caregiver
Exclusion Criteria: 

  • Contraindication to MRI examination (e.g., metal implants, phobia, unable to lie flat in MRI and PET scanners)
  • Scheduled for surgery and/or another invasive procedure within 7 days after [18F]AZD4694 application
  • Medically unstable with an unpredictable clinical course (e.g., people with recent myocardial infarction, stroke, or surgery or with advanced heart insufficiency or acute renal failure)
  • History of exposure to any significant radiation in the last year (e.g., work-related exposure, diagnostic imaging, or radiation therapy)
  • Receiving drug therapy or other treatment known to lead to greatly fluctuating values of hematological or chemical laboratory parameters or to severe side effects (e.g., chemotherapy)
  • Has received anti-amyloid immunotherapy
  • Participation in a clinical study involving an investigational pharmaceutical product within 30 days prior to screening and/or any radiopharmaceutical within 10 radioactive half-lives prior to [18F]AZD4694 administration
  • Brain tumor or other intracranial lesion; disturbance of cerebrospinal fluid circulation (e.g., normal pressure hydrocephalus); history of serious head trauma or brain surgery
  • History or findings of significant neurological or psychiatric illness (other than Alzheimer's disease for participants with probable Alzheimer's)
  • Other untreated disease that can disturb brain function (e.g., vitamin B12 or folic acid deficiency, disturbed thyroid function, anemia)
  • History of alcohol or drug abuse
