Zelquistinel (GATE-251, formerly AGN-241751) is an orally active small-molecule NMDA receptor modulator which is under development for the treatment of major depressive disorder (MDD) by Syndeio Biosciences, and previously by Allergan. [1] [2] [3]

Pharmacology

Zelquistinel acts through a unique binding site on the NMDA receptor, independent of the glycine site, to modulate receptor activity and enhance NMDAR-mediated synaptic plasticity. [4] [5] Its mechanism of action is similar to that of rapastinel. However, unlike rapastinel, zelquistinel is orally bioavailable, exhibits increased potency, and has improved drug properties. [2] [3] [5] The mean half-life of Zelquistinel is reported to be from 1.21 to 2.06 hours, reaching peak plasma concentrations 30 minutes after administration. [6]

In preclinical studies, single doses of zelquistinel demonstrated both rapid-acting (24-hours) and sustained (1-week) antidepressant-like effects and enhancement of long-term synaptic plasticity. [6]

Clinical development

On July 23, 2018, the U.S. FDA granted Fast Track designation to the development of zelquistinel as an investigational new treatment for major depressive disorder. [7]

In 2019, Allergan completed an exploratory phase IIa clinical trial of once-weekly oral zelquistinel in major depressive disorder. [1] [3] [8] By week three, the two highest doses studied reduced MADRS depression scores by 9.5 and 10.6 points compared to a 7.7-point reduction with placebo. This result was considered statistically and clinically significant. [8]

As of 2025, zelquistinel is undergoing a phase IIb clinical trial for depression sponsored by Syndeio Biosciences. [2]
