About this trial

This research will translate findings from preclinical research and provide the initial clinical evidence that orexin antagonism reduces motivation for alcohol, as well as other alcohol-associated maladaptive behaviors in people with Alcohol Use Disorder. This study will also provide basic science information about the orexinergic mechanisms underlying the pharmacodynamic effects of alcohol in humans. As such, the outcomes will contribute to our understanding of the clinical neurobiology of Alcohol Use Disorder. Overall, the proposed work seeks to expand the scope of current clinical neuroscience research on alcohol addiction by focusing on orexin, which has strong preclinical evidence supporting its critical role in addiction but remains unstudied in humans.

Trial outcomes

Primary outcomes

1

Reinforcing Effects of Alcohol

Number of Times Subjects Choose Alcohol (Maximum of 5 Choices) Over Money

Time frame
6 times over approximately 3 week inpatient admission.

Secondary outcomes

1

Craving

Subjects will report their craving during 6 sessions while they are admitted to our inpatient unit. Measured using a 10 point craving questionnaire with higher scores meaning greater craving.

Time frame
6 times over approximately 3 week inpatient admission.
2

Mood

Subjects will complete the Profile of Mood States during 6 sessions while they are admitted to our inpatient unit. Scores range from 0 to 4 with higher scores indicating stronger mood.

Time frame
6 times over approximately 3 week inpatient admission.
3

Alcohol Response

Subjects will complete the Biphasic Alcohol Effects Scale during 6 sessions while they are admitted to our inpatient unit. Scores range from 0 to 10 with higher scores indicating greater responses.

Time frame
6 times over approximately 3 week inpatient admission.
4

Heart rate

Beats per minute. Measured daily during inpatient admission.

Time frame
Daily over approximately 3 week inpatient admission.
