Clinical Trial Summary

The purpose of this research study is to test the safety, tolerability, and effectiveness of the drug Perampanel when used in persons who drink and wish to stop drinking. Perampanel has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of seizures but has not yet been approved to treat alcohol use disorders. For this reason, it is considered an investigational drug. Some people in this study will receive Perampanel alone and some people will receive Perampanel and Disulfiram, this will be determined by the pharmacy.

Description:

Participants will be asked to take a medication (Perampanel or Perampanel + Disulfiram) every day for approximately 8 weeks and have weekly study visits. At these visits, participants will be asked questions about their medical history, drinking behavior and life events, have bloodwork checked routinely, have regular medication counseling, and perform some computer tasks. Throughout the study, there will be regular phone calls from staff. Participants will also be asked to use a device called "Soberlink" which is like an at-home breathalyzer test to help track progress throughout the study. Participants will be randomly assigned (like the flip of a coin) to receive either Perampanel alone or Peramanel and Disulfiram. Participation in this study will last up to 10 weeks. Approximately 20 individuals will participate in this study. This study will sequence all or part of participant's DNA. This is a necessary part of the study. Before starting the study, participants may be referred to an alcohol detoxification program (medical treatment of an alcoholic), if clinically indicated.

Eligibility

Inclusion Criteria:

1. Men and women ages 21-70 with DSM-5 AUD;

Exclusion Criteria:

1. a current, clinically significant physical disease [i.e., neurologic, renal, pulmonary, cardiovascular, hepatic] on the basis of medical history, physical examination, or routine laboratory evaluation that, in the context of the study would represent a risk to the subject, or significant laboratory abnormalities related to hepatic function such as marked elevations of hepatic aminotransferase levels (i.e., AST and ALT) or direct bilirubin;

2. history of renal compromise or current renal disease (as evidenced by serum creatinine above our laboratory's reference limit of 1.7 mg/dL;

3. history of seizure disorder;

4. use of any of a number of medications that might prominently influence drinking patterns or cause risk of harm or injury (e.g., other anticonvulsants, medications to treat AUD, opioid pain medication), currently taking CNS depressants (e.g. benzodiazepines, barbiturates, sedating antihistamines;

5. schizophrenia, bipolar disorder, current major depressive episode, or substantial suicide or violence risk on the basis of history or psychiatric examination;

6. currently dependent on stimulants, opioids or sedatives;

7. subjects with any substantial alcohol withdrawal will be required to be detoxified by regular clinical services prior to study entry;

8. are currently taking any medication that is a moderate to strong CYP3A4 inhibitor or inducer if participants are required to initiate these medications by an outside provider during the course of this study, they will be tapered off the study regimen and we will have them terminate early)

9. are taking phenytoin or warfarin

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent Abstinent Days	Participant will report the number of alcoholic drinks they consumed during the previous weeks period. Participants will be accessed for the full 12 week titration plus treatment period. However, for the purposes of the study, the percent of days the participant was abstinent will be calculated and reported only for the 8 week active treatment period.	End of treatment, up to 12 weeks
Secondary	Change in Alcohol Craving	Alcohol craving will be assessed using the Alcohol Urge Questionnaire (AUG). The AUG is an 8-item survey asking participants to rate their craving for alcohol on a 1 to 7 scale. The answers are summed yielding a score ranging from 7 to 56 with higher scores indicated higher alcohol craving.	Baseline to end of treatment, up to 12 weeks
Secondary	Percent Heavy Drinking Days	Participant will report the number of alcoholic drinks they consumed during the previous weeks period. Based on participant report, the percent of days the participant drank heavily will be calculated over the 8 week active treatment period.	End of treatment, Up to 8 weeks
