Description
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.

- 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.
- If the current dosage regimen is within the approved dose range.
- The daily dose has remained unchanged for at least 6 weeks prior to screening.

Brain MRI performed at Screening (prior to Visit 3) (per centrally read MRI) that shows evidence of any of the following:
- Acute, sub-acute or chronic haemorrhage.
- Cortical infarct (defined as > 1.5 cm in diameter).
- > 1 lacunar infarct (defined as < 1.5 cm in diameter).
- Superficial siderosis.
- History of diffuse white matter disease as defined by a score of 3 on the age-related white matter changes scale [26].

- Has a history of new ischemic or congestive cardiovascular event within the 3 months prior to Visit 3 (Baseline).
- Has a history of or current major psychiatric illness such as schizophrenia or bipolar affective disorder.
- Has a clinician-administered Patient Health Questionnaire (PHQ)-9 score of ≥ 10 or in the Investigator's opinion, depression of a severity that would impact cognitive assessments.
- Subjects with insulin dependent diabetes.
Subjects with uncontrolled hypertension defined as:
- average of 3 systolic blood pressure [SBP]/diastolic blood pressure [DBP] readings > 165/100 mmHg at Screening Visit 2 (blood pressure measurements exceeding these limits may be repeated as warranted by the Investigator, but values must be within the specified limits for the subject to be eligible for the study),
- or persistent SBP/DBP readings > 180/100 mmHg 3 months prior to Baseline (Visit 3, Day 1) that in the opinion of the Investigator are indicative of chronic uncontrolled hypertension.
- Subjects with orthostatic hypotension, defined as a drop of >20 mmHg systolic blood pressure upon standing upright from a seated position within 3 minutes, at Screening Visit 2; testing for orthostatic hypotension may be repeated at Investigator's discretion if there is reason to believe the condition is temporary after addressing the temporary cause.
