Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
There is considerable evidence that Alcohol Use Disorders (AUDs) can be understood as a form of dysregulated learning and are influenced by classical conditioning. This is based on numerous studies indicating that conditioned contextual cues influence craving for alcohol consumption. As a result, there has been considerable interest in extinction-based treatments for AUDs (i.e., treatments that focus on extinguishing the associations between alcohol cues and motivation to drink), referred to as cue exposure treatment To date, extinction-based treatment for AUDs has resulted in disappointing outcomes in clinical trials and there is considerable interest in improving this form of treatment. One novel strategy is the use of pharmacological adjuncts to enhance extinction. Medications that maximize extinction may minimize subsequent reactions to alcohol cues and, in turn, subsequent clinical outcomes. This study is examining whether the medication d-cycloserine (DCS) can enhance extinction to alcohol cues. Recent basic research has revealed that DCS enhances extinction to fear cues and several lines of evidence suggest that DCS may also enhance extinction to alcohol cues. Therefore, DCS may serve as a useful pharmacological adjunct to extinction-based treatment for AUDs. Our primary aim is to examine whether, compared to placebo, DCS (50 mg) will enhance extinction to alcohol cues under controlled laboratory conditions in treatment-seeking individuals with alcohol use disorders. We hypothesize that DCS will generate greater extinction compared to placebo during the subsequent extinction session as measured by attenuated craving in response to alcohol cues. Furthermore, we hypothesize that DCS will generate greater extinction compared to placebo at follow-up assessments. This study is a proof-of-concept test of whether DCS can reduce reactions to alcohol cues under controlled laboratory conditions. It is a preliminary study using a subclinical number of extinction sessions and medication administrations to establish whether or not DCS improves extinction in the laboratory. If proof-of-concept is supported, it will suggest that a clinical trial is warranted. A clinical sample and clinical context are used to maximize the potential generalizability from this exploratory study.
