Inclusion Criteria

  • Elevated brain tau pathology defined as Braak 3 region of interest standardized uptake value ratio (ROI SUVR) greater than (>) 1.1 (or equivalent based on emerging data) on a screening tau PET scan, reviewed centrally by a qualified reader to enrich for probability of disease progression during the study - Clinical Dementia Rating (CDR) global score of 0 at screening and baseline - Mini Mental State Examination (MMSE) greater than or equal to (>=) 27 (with educational adjustment) at screening - Able to read and write and with a minimum 5 years of formal education as reported by participant and study partner at screening - A participant must be of non-childbearing potential
