  • -Have adequate literacy, vision, and hearing for neuropsychological testing at screening.
  • -Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies

  • -Have a centrally read MRI demonstrating presence of amyloid-related imaging abnormalities (ARIA-E), >4 cerebral microhemorrhages, more than 1 area of superficial siderosis, any macrohemorrhage or severe white matter disease at screening.
  • -Have had prior treatment with a passive anti-amyloid immunotherapy <5 half-lives prior to randomization.
