Altering Memories That Increase Risk of Relapse in Alcohol Use Disorders

Phase 1

Completed

Conditions: Alcohol Use Disorder
Alcohol Dependence

Interventions: Drug: Placebo
Drug: Rapamycin

Registration Number: NCT03732248

Lead Sponsor: Medical University of South Carolina

Brief Summary: The purpose of this study is to examine the effects of rapamycin (sirolimus) versus a placebo, an inactive substance, on responses to alcohol cues in individuals with alcohol use disorder. Rapamycin (sirolimus) is a FDA-approved antibiotic and immunosuppressive drug that is currently used to (a) prevent organ transplant recipients from rejecting their transplants (b) treat cardiovascular diseases, and (c) treat some forms of cancer. Rapamycin (sirolimus) is not FDA-approved to treat alcohol use disorder. The use of rapamycin (sirolimus) in this study is investigational, meaning that the study medication is not a proven treatment for alcohol use disorder. The study will examine the medication's use as a potential treatment for alcohol use disorder, as well as how safe and tolerable it is to take.

Study Design: PARALLEL

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Placebo is administered in three 5mg oral capsules. This administration happens once during the first visit.
Rapamycin (sirolimus) 15mg	Rapamycin	Rapamycin (sirolimus) is administered in three 5mg oral capsules. This administration happens once during the first visit.

Primary Outcome Measures

Name	Time	Method
Evaluate Safety of Rapamycin (Sirolimus) at Second Visit.	MOSES will be assessed at the second study visit, 24 hours after medication administration.	Safety will be monitored through adverse events checks by the study physician assistant (PA). The study PA will use the Monitoring of Side-Effects Scale (MOSES) to track if there are any adverse effects. Participants will be recorded as those who report any adverse event vs. no adverse events.
Evaluate Safety of a Single 15 mg Dose of Rapamycin (Sirolimus) at First Visit.	MOSES will be assessed at the first study visit on day 1.	Safety will be monitored through adverse events checks by the study physician assistant (PA). The study PA will use the Monitoring of Side-Effects Scale (MOSES) to track if there are any adverse effects. Participants will be recorded as those who report any adverse event vs. no adverse events.
Evaluate Safety of Rapamycin (Sirolimus) at Third (Last) Visit.	MOSES will be assessed at the third study visit, approximately 10 days after medication administration.	Safety will be monitored through adverse events checks by the study physician assistant (PA). The study PA will use the Monitoring of Side-Effects Scale (MOSES) to track if there are any adverse effects. Participants will be recorded as those who report any adverse event vs. no adverse events.

Secondary Outcome Measures

Name	Time	Method
Drinks Per Drinking Day Between Visit 2 and Visit 3	At participant's last study visit, approximately 10 days.	Participants will be given a timeline to record any drinking that occurs between visits 2 and 3. Time line follow back procedures were used to record daily drinking behavior for all study days; recorded as standard drinks.
Heavy Drinking Days Between Visit 2 and Visit 3	At participant's last study visit, approximately 10 days.	Participants will be given a timeline to record any drinking that occurs between visits 2 and 3. Time line follow back procedures were used to record daily drinking behavior for all study days; recorded as standard drinks. Heavy drinking days are defined as \>=5 drinks per day for Males and \>=4 drinks per day for Females.
Drinking Days Between Visit 2 and Visit 3	At participant's last study visit, approximately 10-14 days.	Participants will be given a timeline to record any drinking that occurs between visits 2 and 3. Time line follow back procedures were used to record daily drinking behavior for all study days; recorded as standard drinks. The total number of days where drinking was recorded is summed for each participants during the study window.
