ENX-104
A potent D2/D3 antagonist in development for major depressive disorder (MDD) with anhedonia
Anhedonia is a hallmark symptom of MDD. Dysregulated dopaminergic neurotransmission, particularly in brain reward systems, is thought to underlie anhedonia.1
ENX-104 was engineered to directly modulate dopaminergic transmission in brain reward systems by increasing dopamine release via potent antagonism of presynaptic D2/D3 autoreceptors and provides an excellent pharmacokinetic profile that supports once-daily dosing.2
ENX-104 is rapidly advancing into clinical studies, where it is expected to improve symptoms of anhedonia while delivering a favorable safety and tolerability profile.2
No currently approved treatments specifically target anhedonia, a disabling symptom defined as the inability to feel pleasure1 — modulating dopaminergic reward systems is a novel approach to manage this core feature of MDD
