A Pilot Synaptic Vesicle Glycoprotein 2A (SV2A) PET Study to Evaluate the Effect of CT1812 Treatment on Synaptic Density in Participants with Mild to Moderate Alzheimer s Disease


Alzheimer's Disease

Phase IB

What is the purpose of this trial?

CT1812 is a highly brain penetrant novel

sigma-2/PGRMC1 antagonist molecule that may prevent and displace the binding of Aβ

oligomers to neuronal synapses, thereby slowing the progression of Alzheimer’s disease. This is

an 8-month, placebo-controlled, Phase 1b single-center trial designed to evaluate the safety and

tolerability of CT1812 and to determine the effects of CT1812 on brain synaptic density in

Alzheimer’s disease. During the 169-day treatment period, participants will be randomized to

receive study drug (300 mg or 100 mg) or placebo that will be administered orally (66%

probability of receiving active study medication). Subjects will have up to 3 brain MRI scans, up

to 6 PET scans, and up to 2 lumbar punctures provided with study participation. Permits

concurrent treatment with cholinesterase inhibitors and/or memantine.
