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:

• Does NTX-2001 affect alcohol consumption in adults with AUD?
• Is NTX-2001 safe and well tolerated in adults with AUD?

Researchers will compare the effects of NTX-2001 with matching placebo (look-alike capsule that contains no drug).

Participants will:

• Take NTX-2001 or matching placebo every day for 2 weeks
• Visit the clinic 4 times over the course of 10 weeks
