Key inclusion criteria
- Patients aged 60 to 85 years, inclusive, with a NIA-AA diagnosis of mild cognitive
impairment (MCI) due to AD or early stage mild dementia due to AD. AD diagnosis should
be made by an appropriately qualified medical specialist and AD pathology should be
confirmed by either:

1. Historical records of amyloid CSF assessment or

2. Historical records of amyloid PET scan or

3. If neither historical records are available, then AD pathological diagnosis
confirmation should be offered at screening:

abuse (including alcohol, as defined in DSM-V or in the opinion of the investigator)

Brief summary
Phase 2b/3 48-week study to evaluate the effects of ANAVEX2-73 on cognition and function
after 48 weeks of daily treatment. Additional outcome measures include refined measures of
sleep, behavioral and psychological symptoms typically observed in AD, changes in daily
functioning of participants and changes in caregiver burden, as well as changes in quality of
life measures of both, patients and caregivers during treatment with ANAVEX2-73.
