Inclusion criteria

✓. Subjects between the ages of 50 and 85 (inclusive) at the time of Screening Visit 1. Subjects 86 to 90 years of age (inclusive) can be enrolled, provided that the Medical Monitor reviews the subject's medical condition during the screening process and approves enrolment.
✓. Dementia of mild to moderate severity, as classified by MMSE score between 14 to 26, inclusive, at Screening Visit 1.
✓. Meets diagnostic clinical criteria of probable Alzheimer's dementia according to the National Institute on Aging and the Alzheimer's Association (NIA-AA) \[25\].
✓. Magnetic resonance imaging prior to Visit 3 (Baseline) compatible with a diagnosis of probable AD.
✓. Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) brain scan showing a pattern typical for AD according to central PET reader (with areas of glucose hypometabolism in posterior cingulate, temporal, parietal, and/or prefrontal cortices, as per criteria in imaging manual).
✓. Confirmed APOE negative genotype result obtained by the central laboratory prior to Screening Visit 2 or documented prior to screening.
✓. Subjects taking the following cholinesterase inhibitors (ChEI): donepezil, galantamine, or rivastigmine; and/or GV-971, and/or memantine and/or other agents which may impact cognition (e.g., Souvenaid®, NeuroAidTM, Cerefolin®, Gingko biloba, etc) are eligible for enrolment:
✓. If the subject has been taking such medication(s)/products for 3 months or more at Screening Visit 1.

✕. In the opinion of the Investigator, has presence or history of an advanced, severe, progressive, or unstable disease of any type that could interfere with efficacy and safety assessments, or put the subject at risk.
✕. Has any medical or neurological condition, other than AD, that could explain the subject's dementia (e.g., structural abnormality, traumatic brain injury, stroke, epilepsy, Parkinson's disease, alcohol-related dementia, etc.)
✕. Has a modified Hachinski Ischemia score greater than (\>) 4 at Screening Visit 2.
✕. Has a history or clinical laboratory evidence of cerebrovascular disease (stroke, transient ischemic attack, haemorrhage), or diagnosis of possible, probable, or definite vascular dementia at Screening Visit 1 in accordance with National Institute of Neurological Disorders and Stroke criteria.
