PET Imaging Agent [18F]NAV4694 for Detecting Cerebral Beta-Amyloid

Active, not recruiting

This Phase III study will determine the efficacy and safety of the agent [18F]NAV4694 used in positron emission tomography (PET) brain imaging. The test is designed to detect beta-amyloid, a protein commonly found in the brains of people with Alzheimer's disease. Participants must have a life expectancy of about 6 months.

  • Life expectancy of approximately 6 months
  • Ability to provide informed consent and exhibit adequate visual, auditory, and communication capabilities, including the ability to lie flat in an MRI or PET scanner for about 1 hour
  • Willingness to donate brain for post mortem examination upon death
  • MRI and/or [18F]NAV4694 scans do not need to be repeated if performed within 12 months prior to this study

  • Female subjects of child-bearing potential or with a positive urine pregnancy test on the day of [18F]NAV4694 injection
  • Scheduled for surgery and/or another invasive procedure within 7 days after [18F]NAV4694 injection
  • Severe cerebral macrovascular disease or brain tumor
  • Has received any contrast material (X-ray, MRI) or radiopharmaceutical within 48 hours prior to receiving the investigational agent
  • Has received a therapeutic radiopharmaceutical (for example, 131I) within 10 days prior to receiving the investigatonal agent
  • Any radiopharmaceutical administration within 10 radioactive half-lives prior to receiving the investigational agent or planned within 7 days after receiving the agent
  • Contraindication to MRI examination, such as metal implants or phobia
  • Allergy to investigational product or any of its ingredients

Investigators will compare the results of brain imaging with [18F]NAV4694 PET with the results of autopsy to determine the agent's ability to detect beta-amyloid in certain brain regions and enable earlier identification of Alzheimer's disease and monitoring of disease progression. NAV4694 is a fluorine-18 labeled precision radiopharmaceutical candidate, used in PET imaging to evaluate people with signs or symptoms of cognitive impairment such as Alzheimer's disease. NAV4694 binds to beta-amyloid deposits in the brain that can then be imaged in scans.
