A phase 1 clinical trial of the sigma-2 receptor complex allosteric antagonist CT1812, a novel therapeutic candidate for Alzheimer's disease.

ABSTRACT:

Background

Elayta (CT1812) is a novel allosteric antagonist of the sigma-2 receptor complex that prevents and displaces binding of Aβ oligomers to neurons. By stopping a key initiating event in Alzheimer's disease, this first-in-class drug candidate mitigates downstream synaptotoxicity and restores cognitive function in aged transgenic mouse models of Alzheimer's disease.

Methods

A phase 1, two-part single and multiple ascending dose study was conducted in 7 and 4 cohorts of healthy human subjects, respectively. In part A, healthy, young subjects (<65 years old) received CT1812 doses ranging from 10 to 1120 mg (6:2 active to placebo [A:P] per cohort). In part B, subjects were administered 280, 560, and 840 mg once daily for 14 days (8:2 A:P per cohort). An elderly cohort, ag
