The Effects of NTX-2001, a Novel TAAR1 Partial Agonist, on Alcohol Consumption in Adults With Alcohol Use Disorder: A Phase 1b, Randomized, Placebo-Controlled, Proof-of-Concept Study

The primary goal of this Phase 1b clinical trial is to evaluate the effects of a novel TAAR1 receptor partial agonist (NTX-2001) in adults with Alcohol Use Disorder (AUD). The main questions this trial aims to answer are:
