A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of PT150 in reducing the behavioral and physical effects of stress and alcohol use in individuals diagnosed with alcohol use disorder (AUD). Participants will undergo a stress-induction procedure using the Cold Pressure Test (CPT) while their behavioral and neuroendocrinological responses are monitored. The study employs computerized data collection to enhance accuracy and efficiency in data management. Participants will be seated comfortably during the sessions, which will include assessments of alcohol demand, craving, mood, and salivary cortisol levels.

Why it matters

Potential benefit: If successful, this study could provide a new therapeutic option for individuals struggling with alcohol use disorder.

How similar studies have gone: While this approach is novel, previous studies have shown promise in using stress-induction techniques to assess behavioral responses in alcohol use disorder.
