A Study of NTX-1472 in Social Anxiety Disorder

A Phase 2, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Assess the Safety, Tolerability, and Efficacy of NTX-1472, a V1a Receptor Antagonist, in Adults With Social Anxiety Disorder

The primary goal of this Phase 2 clinical trial is to determine the effects of a novel V1a receptor antagonist (NTX-1472) in adults with Social Anxiety Disorder (SAD). The main questions this trial aims to answer are:

• Is NTX-1472 safe and well tolerated in adults with SAD?
• How effectively does NTX-1472 treat adults with SAD?

Researchers will compare the effects of NTX-1472 with matching placebo (a look-alike capsule that contains no drug).

Participants will:

• Take NTX-1472 or matching placebo every day for 8 weeks
