Is this trial a fit for you?

Likely a good fit

Adults aged 21–60 with DSM-5–diagnosed alcohol use disorder, BMI 18–35 kg/m2, able to consent in English and attend the clinic visits in New Haven, CT, and not currently seeking alcohol treatment are the best candidates.

Probably not a fit

People actively seeking alcohol treatment, those with current non-nicotine substance use disorders or psychotic disorders, or those unable to travel to the Yale site are unlikely to be eligible or to benefit from participation.

What this trial studies

NTX-2001, a TAAR1 receptor partial agonist, is given daily for two weeks and compared with a matching placebo in adults with alcohol use disorder. This Phase 1b trial emphasizes safety and tolerability while collecting early data on alcohol consumption, with participants attending four clinic visits over a 10-week period. Eligible participants are adults aged 21–60 with DSM-5–confirmed AUD and BMI between 18 and 35 kg/m2, and those currently seeking formal alcohol treatment are excluded. The study is sponsored by Newleos Therapeutics and conducted in collaboration with Yale University School of Medicine.

Why it matters

Potential benefit: If successful, NTX-2001 could provide a new medication option to help reduce drinking and cravings in people with alcohol use disorder.

How similar studies have gone: TAAR1-targeting drugs represent a relatively new approach with supportive preclinical data and limited early human data, so applying this mechanism to alcohol use disorder is novel and not yet proven.
