Brief summary

The purpose of this study is to determine the effects of treatment with carisbamate compared to treatment with placebo, on alcohol-induced stimulant and subjective effects in non-treatment seeking alcohol-dependent human volunteers.

Detailed description

This within-subjects placebo-controlled experimental protocol will assess the effects of carisbamate (600mg qd) on the positive subjective effects of alcohol in non-treatment-seeking alcohol-dependent volunteers. Participants will receive study drug (carisbamate or placebo) from days 2- 4. On day 4, study drug will be followed by alcohol (0.8g/kg; 16% by volume) and a placebo beverage (1% by volume as a mask), both separated by 2 hours. Physiologic, subjective effects and BAL will be obtained after the alcohol challenges. Participants will be discharged on day 4 and asked to return a week later to repeat the study under the alternate study drug condition (active carisbamate vs. placebo).

Meet DSM-IV TR criteria for alcohol abuse; participants may or may not meet criteria for nicotine dependence. Nicotine dependence is allowed but not required because most alcohol users smoke cigarettes. 4. Have a self-reported history of using alcohol. 5. Have vital signs as follows: resting pulse must be \< 90 bpm and the blood pressure must be \< 150 mmHg systolic and \< 90 mmHg diastolic. 6. Have hematology and chemistry laboratory tests that are within normal (+/- 10%) limits with the following exceptions: * liver function tests (total bilirubin, ALT, AST, and alkaline phosphatase) \< 3 x the upper limit of normal, and b) kidney function tests (creatinine and BUN) within normal limits 7. Have a baseline EKG that demonstrates clinically normal sinus rhythm, clinically normal conduction, and no clinically significant arrhythmias 8. Have a medical history and brief physical examination demonstrating no clinically significant contraindications for study participation, in the judgment of the admitting physician and the principal investigator.

Exclusion criteria

1. Meet DSM IV TR criteria for dependence on drugs other than alcohol or nicotine. 2. Have any history or evidence suggestive of seizure disorder or brain injury 3. Have any previous medically adverse reaction to alcohol, including loss of consciousness, chest pain, or epileptic seizure 4. Have neurological or psychiatric disorders, such as: * psychosis, bipolar illness or major depression as assessed by SCID * organic brain disease or dementia assessed by clinical interview * history of any psychiatric disorder which would require ongoing treatment or which would make study compliance difficult * history of suicide attempts within the past year and/or current suicidal ideation/plan 5.

MeasureTime frameDescription
Mean Biphasic Alcohol Effects Scale (BAES) Scores15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages, stimulant ratingsThe Biphasic Alcohol Effects Scale (BAES) is a self-report, unipolar adjective rating scale that is designed to measure both stimulant and sedative effects of alcohol. The BAES consists of 14 items that are rated on a eleven-point scale. The Sedation and Stimulation subscales are calculated by summing the following items (for the 14-point scale): Stimulation: = BAES3 + BAES4 + BAES5 + BAES11 + BAES12 + BAES13 +BAES14/ Sedation: = BAES1 + BAES2 + BAES6 + BAES7 + BAES8 + BAES9 + BAES10. Individuals are instructed to rate the extent to which drinking alcohol has produced these feelings in you at the present time from 0 (not at all) to 10 (extremely). Higher scores on the Sedative Subscale represent extreme sedation (0 not at all sedated - 70 extremely sedated). Higher scores on the Stimulant Subscale represent extreme stimulation (0 not at all stimulated - 70 extremely stimulated). Scale scores are calculated as the sum of respective stimulant and sedative effects items.
Mean Alcohol Urge Questionnaire (AUQ) Scores15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages.The Alcohol Urge Questionnaire (AUQ) consists of eight statements about the respondent's feelings and thoughts about drinking as they are completing the questionnaire (i.e., right now). Drinking refers to various types of alcohol, including beer, wine and liquor. The respondent is asked to respond to each statement about alcohol craving via a 7-item Likert scale ranging from 0-strongly disagree to 6- strongly agree. Item scores were averaged and the total score also ranges from 0-6.
Mean Positive and Negative Affect Schedule (PANAS) Scores15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages.The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. Each item is rated on a 5-point scale of 1 (not at all) to 5 (very much). Range between 10 and 50 points. Higher positive affect scores indicated a better outcome, while lower negative affect scores indicated a better outcome.
MEAN DRUG EFFECTS QUESTIONNAIRE (DEQ) SCORES15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages.Self-reported subjective drug effects questionnaire evaluated whether a respondent was currently affected by doses of alcohol. Participants completed VAS at regular intervals after ingesting active alcohol (0.8g/kg; 16% by volume) or placebo (1% by volume as a mask). The questionnaire assessed the extent to which subjects experience four subjective states: Feel Drug, Feel High, and Want More. The Feel Drug, Feel High, Like Drug, Dislike Drug, and Want More subscales are reported.Each item is rated on a 100-point scale of 1 (not at all) to 100 (extremely). 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome.

The Biphasic Alcohol Effects Scale (BAES) is a self-report, unipolar adjective rating scale that is designed to measure both stimulant and sedative effects of alcohol. The BAES consists of 14 items that are rated on a eleven-point scale. The Sedation and Stimulation subscales are calculated by summing the following items (for the 14-point scale): Stimulation: = BAES3 + BAES4 + BAES5 + BAES11 + BAES12 + BAES13 +BAES14/ Sedation: = BAES1 + BAES2 + BAES6 + BAES7 + BAES8 + BAES9 + BAES10. Individuals are instructed to rate the extent to which drinking alcohol has produced these feelings in you at the present time from 0 (not at all) to 10 (extremely). Higher scores on the Sedative Subscale represent extreme sedation (0 not at all sedated - 70 extremely sedated). Higher scores on the Stimulant Subscale represent extreme stimulation (0 not at all stimulated - 70 extremely stimulated). Scale scores are calculated as the sum of respective stimulant and sedative effects items.

MEAN DRUG EFFECTS QUESTIONNAIRE (DEQ) SCORES

Self-reported subjective drug effects questionnaire evaluated whether a respondent was currently affected by doses of alcohol. Participants completed VAS at regular intervals after ingesting active alcohol (0.8g/kg; 16% by volume) or placebo (1% by volume as a mask). The questionnaire assessed the extent to which subjects experience four subjective states: Feel Drug, Feel High, and Want More. The Feel Drug, Feel High, Like Drug, Dislike Drug, and Want More subscales are reported.Each item is rated on a 100-point scale of 1 (not at all) to 100 (extremely). 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome.

Time frame: 15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages.

Mean Positive and Negative Affect Schedule (PANAS) Scores

The Positive and Negative Affect Schedule (PANAS) is a self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. Each item is rated on a 5-point scale of 1 (not at all) to 5 (very much). Range between 10 and 50 points. Higher positive affect scores indicated a better outcome, while lower negative affect scores indicated a better outcome.

Time frame: 15, 30 and 60 minutes after consumption of placebo (1% alcohol by volume) and alcohol (0.8g/kg; 16% by volume) beverages.

Population: This within-subjects study included 2 treatment arms (placebo \& carisbamate), during both arms subjects completed study procedures twice, once after consuming placebo (1% alcohol by volume) and once after consuming alcohol (0.8g/kg; 16% by volume). The data here represent the means, following consumption of alcohol and placebo beverage, for the 8 subjects that completed both study arms.
