Study Arms (2)

DNL747 First, Placebo Second

EXPERIMENTAL

Subjects will receive DNL747 for 29 days for the first period and then will switch to placebo for 29 days for the second period. There will be a 14-day washout period between the 2 treatment periods.

Eligibility Criteria

Age55 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women of non-childbearing potential and men, aged 55-85 years
  • AD diagnosis based on the 2011 National Institute on Aging-Alzheimer's Association Guidelines
  • Supportive evidence for diagnosis of AD based upon positive CSF Aβ42 test, or documented history of positive amyloid-specific PET scan
  • Screening MMSE score of 16-26 points
  • Screening CDR Global Score of 0.5-1.0
  • Availability of a person ("caregiver") who, in the investigator's judgment, has frequent and sufficient contact with the participant and is able to provide accurate information regarding the participant's cognitive and functional abilities, agrees to provide information at clinic visits that require input for scale completion, assists the participant with compliance for at-home study treatment administration, and signs the necessary consent form (note: the caregiver is not required to stay in the unit)
  • Approved AD treatments (acetylcholinesterase inhibitors ± memantine) and other prescription medications must be stable for ≥1 month prior to screening and anticipated to be stable over the duration of the study

You may not qualify if:

  • Clinical history within 2 years of the screening visit or current evidence of any neurological or neurodegenerative disorder other than AD that is associated with transient or sustained alterations in cognition
  • Magnetic resonance imaging (MRI) at screening (or within 1 year of screening visit) consistent with any neurological or neurodegenerative disorder other than AD that is associated with transient or sustained alterations in cognition
