Overview
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
- Visit the clinic 6 times over the course of 14 weeks for checkups and tests
