A Study for the Treatment of Alcohol Dependence

Eli Lilly and Company375 enrolled

Overview

The Primary objective of this study is to test whether LY2196044 can reduce the number of heavy drinking days per month in people with alcohol dependence. Each subject will undergo a screening and assessment period (including medication washout) prior to randomization into a 16 week double blind treatment period.

Markedly diminished effect with continued use of the same amount of alcohol. 2. Consume alcohol, often in larger amounts or over a longer period than was intended. 3. Have a persistent desire or unsuccessful effort(s) to reduce or control alcohol use. * Drink on average more than 14 drinks (women) or 21 drinks (men) per week with at least 2 heavy drinking days per week (≥4 drinks/day for women and ≥5 drinks/day for men) during the consecutive 30 day period prior to Screening and maintained through Randomization. * Endorse abstinence or reduction in drinking. * Female subjects of childbearing potential must have a negative urine pregnancy test and agree to use a reliable method of birth control during the study and for 2 months following the last dose of study drug. Exclusion Criteria: * Have experienced an acute alcohol withdrawal syndrome within the past 6 months or are currently at significant risk of suffering an acute alcohol withdrawal syndrome. * Have a history of serious head injury, intracranial neoplasm or hemorrhage, prior seizure (other than remote history of childhood febrile seizure), or other condition that would place the subject at increased risk of seizure. * Have ever taken anticonvulsants for seizure control. * Are diagnosed with substance dependence or abuse (other than alcohol, cannabis, nicotine, or caffeine) within 6 months prior to Screening. * Are receiving intensive behavioral or psychological therapy, delivered by a licensed or certified alcohol treatment specialist, for alcohol dependence. * Meet criteria for a lifetime diagnosis of Schizophrenia, Schizoaffective Disorder, Bipolar I Disorder, or other psychoses. * Have signs and symptoms of an active illness within the past 6 months of Screening for a diagnosis of Major Depressive Disorder (MDD) or Anxiety Disorder, or have a Cognitive Disorder diagnosed by clinical assessment.

Primary Outcomes

Percentage of Heavy Drinking Days at Week 16 Endpoint

The Timeline Followback Method assesses the subject's daily drinking by means of a calendar that covers a specific time period and was used to assess the number of heavy drinking days.
