Descriptive Information

• Brief Title: Clinical Trial of CT1812 in Mild to Moderate Alzheimer's Disease
• Official Title: A Randomized, Double-Blind, Placebo-Controlled, Phase I Study of the Safety & Pharmacokinetics of Two Doses of CT1812 in Subjects With Mild to Moderate Alzheimer's Disease
• Brief Summary: This is a multi-center, randomized, double-blind, placebo-controlled, parallel group study of two doses of CT1812 in adults with mild to moderate Alzheimer's Disease to evaluate the safety and tolerability of oral CT1812, administered for 28 days. This trial may include up to 8 qualified investigator sites in Australia.
• Detailed Description: Screening procedures will occur up to 42 days. Eligible subjects will randomized at the clinic on Day 1 and receive the first dose of study drug. Dosing for 28 days thereafter off-site and a total of 5 clinic visits over the treatment period for safety and lab assessments. Then a 7 day post-treatment completion follow-up visit (Day 35) and End of Study for last safety assessments (Day 49).

2. Men and women, 50-80 years in age inclusively with a diagnosis of mild to moderate Alzheimer's disease according to the 2011 NIA-AA. Women must be neither pregnant nor nursing, and are either surgically sterile, postmenopausal or premenopausal using an acceptable method of contraception.
3. Previous decline in cognition for more than six months.
4. Neuroimaging (MRI) obtained within the previous 6 months or during screening, consistent with the clinical diagnosis of Alzheimer's disease.
5. MMSE 18-26 inclusive.

7. Modified Hachinski Ischemia score ≤ 4.
8. Formal education of eight or more years.
9. Living at home or in a community setting (assisted living) without continuous nursing care. Each subject must have a reliable caregiver who sees them at least 3 times weekly, can oversee the administration of study drug, and is willing and able to participate in all clinic visits and some study procedures. Responsible caregiver must provide written informed consent to participate.
10. Concurrent use of acetylcholinesterase inhibitors or memantine must be stable for 90 days prior to screening and not expected to change.

Exclusion Criteria:

1. History of or screening brain MRI scan indicative of significant abnormality, including, but not limited to, prior hemorrhage or infarct > 1 cm3, >3 lacunar infarcts, cerebral contusion, encephalomalacia, aneurysm, vascular malformation, subdural hematoma, hydrocephalus, space-occupying lesion (e.g. abscess or brain tumor such as meningioma).

2. Clinical or laboratory findings consistent with:

   1. Other primary degenerative dementia,
   2. Other neurodegenerative condition
   3. Seizure disorder
   4. Other infectious, metabolic or systemic diseases affecting the central nervous system
