Effect of CT1812 Treatment on Brain Synaptic Density

This is a single-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 up 180 days for the Primary study and another 180 days for the double-blind extension study.

Each participant and caregiver participated in a screening period of up to 60 days, followed by the primary double-blind treatment period of 24 weeks (169 days +/-2) followed by an optional double-blind extension treatment period of another 24 weeks (337 days +/-2).
