About the study

This is Phase 3 study, multi-centre, double-blind, placebo controlled, parallel group to evaluate the effects of AC-SD-03 on the efficacy and safety among participants with mild to moderate Alzheimer's Disease.

Who can take part?

You may be eligible to participate in the study if you meet the following criteria:

Inclusion criteria
  1. inclusive) at the time of Screening Visit 1. Subjects 86 to 90 years of age (
  2. inclusive) can be enrolled, provided that the Medical Monitor reviews the subject's medical condition during the screening process and approves enrolment. 2. Dementia of mild to moderate severity, as classified by MMSE score between 14 to 26, inclusive, at Screening Visit 1. 3. Meets diagnostic clinical criteria of probable Alzheimer's dementia according to the National Institute on Aging and the Alzheimer's Association (NIA-
  3. AA) [25]. 4. Magnetic resonance imaging prior to Visit 3 (
  4. Baseline) compatible with a diagnosis of probable AD. 5. Fluorodeoxyglucose Positron Emission Tomography (FDG-
  5. 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). 6. Confirmed APOE negative genotype result obtained by the central laboratory prior to Screening Visit 2 or documented prior to screening. 7. 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,
  6. etc) are eligible for enrolment: 1. If the subject has been taking such medication(s)/products for 3 months or more at Screening Visit 1. 2.

In the opinion of the Investigator, the subject's medical condition, except for dementia, has been stable for at least 3 consecutive months prior to Screening Visit 1. 9. Subjects do not have active suicidal thoughts (answers 'yes' to questions 4 or 5, on the Columbia-Suicide Severity Rating Scale [C-SSRS]) within 6 months preceding Screening Visit 2 or Visit 3 (Baseline). Additionally, subjects have no active history of suicide attempt in the previous 2 years or more than 1 lifetime suicide attempt, nor are they at serious suicidal risk, in the opinion of the Investigator. 10. The subject is able to comply with protocol testing and procedures for the entire length of the trial. 11. Has a permanent caregiver (subject's caregiver is not expected to change during the
  7. trial) who is willing to attend all visits, oversee the subject's compliance with protocol-specified procedures and IP administration, and report on subject's status. Caregiver must have, in the opinion of the Investigator, enough contact with the subject to be able to perform the duties described above. 12. The subject and caregiver are, in the Investigator's judgement, proficient in the language in which the trial assessments will be completed, and have hearing, vision and physical abilities adequate to perform assessments (corrective aids allowed). 13. Subject and caregiver must provide full written informed consent prior to the performance of any protocol-specified procedure; or if subject is unable to provide informed consent due to cognitive status, provision of informed consent by cognitively intact legally acceptable representative (where this is in accordance with local laws, regulations and ethics committee policy). 14. Subject is able to ingest oral medication. 15. Subject is able to tolerate a 5 g dose of tricaprilin (formulated as 12.5 g of AC-SD-
  8. 03) as per sentinel dose challenge at Visit 3 (Baseline).
Exclusion criteria
  1. tablespoon) per day is allowed. Use of MCT-containing products is not allowed at any time during trial participation. 2. Use of any other investigational agent within 60 days prior to Screening Visit 1. 3. Has a known allergy or hypersensitivity to triglycerides. 4. 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. 5. 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.) 6. Has a modified Hachinski Ischemia score greater than (>) 4 at Screening Visit 2. 7. 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. 8. Brain MRI performed at Screening (prior to Visit
  2. 3) (per centrally read
  3. MRI) that shows evidence of any of the following: 1. Acute, sub-acute or chronic haemorrhage. 2. Cortical infarct (defined as > 1.5 cm in diameter). 3. > 1 lacunar infarct (defined as < 1.5 cm in diameter). 4. Superficial siderosis. 5. History of diffuse white matter disease as defined by a score of 3 on the age-related white matter changes scale [26]. 6. Any finding that, in the opinion of the Investigator, might be a contributing cause of subject's dementia, might pose a risk to the subject, or might prevent a satisfactory MRI assessment for safety monitoring. 9. Has a history or clinical laboratory evidence of moderate congestive heart failure defined by the New York Heart Association Criteria (Class I to IV). 10. Clinically significant ECG abnormalities at Screening Visit 2, for example: 1. Evidence of atrial fibrillation on ECG or history of atrial fibrillation that is not currently controlled 2.
