Primary: The primary objective of the study is to compare the efficacy of intranasal oxytocin in reducing the weekly percentage of heavy drinking days over the 10 weeks of maintenance treatment among subjects with moderate to severe Alcohol Use Disorder (AUD). A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men. Secondary: Secondary objectives include assessment of other measures of the effects of oxytocin compared with placebo on reduction of alcohol use as well as effects on psychological assessments, alcohol craving, alcohol-related consequences, cigarette smoking and other nicotine use, retention in the study, safety, and application site (nares) tolerability throughout the study.

Weekly Percentage of Heavy Drinking Days
The primary efficacy endpoint is the weekly percentage of heavy drinking days during the 10-week maintenance treatment period. A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men. Drinking data will be collected by the Timeline Followback (TLFB) method.
Time frame: Weeks 3-12
Percentage of Subjects With no Heavy Drinking Days
Percentage of subjects with no heavy drinking days during the 10-week Maintenance period
Time frame: weeks 3-12
Percentage of Subjects Abstinent From Alcohol
Percentage of subjects abstinent from alcohol during the 10-week Maintenance period
Time frame: Weeks 3-12
Percentage of Subjects With at Least a 1-level World Health Organization (WHO) Drinking Risk Category Decrease
Percentage of subjects with at least a 1-level World Health Organization (WHO) drinking risk category decrease from the baseline level to (the period including the 28 days before screening) to the level during the treatment phase (Study Weeks 3-12). The WHO levels of average alcohol consumption per day vary by Sex of participants and are as follows: Males Females Low Risk 1 to 40g 1 to 20g Medium Risk 41 to 60g 21 to 40g High Risk 61 to 100g 41 to 60g Very High Risk 101+g 61+g where 14g = 1 SDU (WHO-2000). In computing the WHO alcohol consumption level, average drinks per day were used, computed as the sum of all drinks in the 28 day period divided by the number of days with non-missing drinking data in that period. Abstinent subjects were included in a separate "Abstinent" category.
Time frame: weeks 3-12
Percentage of Subjects With at Least a 2-level World Health Organization (WHO) Drinking Risk Category Decrease
Percentage of subjects with at least a 2-level World Health Organization (WHO) drinking risk category decrease from the baseline level to (the period including the 28 days before screening) to the level during the treatment phase (Study Weeks 3-12). The WHO levels of average alcohol consumption per day vary by Sex of participants and are as follows: Males Females Low Risk 1 to 40g 1 to 20g Medium Risk 41 to 60g 21 to 40g High Risk 61 to 100g 41 to 60g Very High Risk 101+g 61+g where 14g = 1 SDU (WHO-2000). In computing the WHO alcohol consumption level, average drinks per day were used, computed as the sum of all drinks in the 28 day period divided by the number of days with non-missing drinking data in that period. Abstinent subjects were included in a separate "Abstinent" category.

Number of Alcohol Use Disorder Symptoms (MINI)
The MINI (paper version 7.0.2) is a short structured diagnostic interview, developed jointly by psychiatrists and clinicians in the United States and Europe, for DSM-5 and ICD-10 psychiatric disorders (Sheehan-1998). This scale is a count of the number of alcohol use disorder symptoms. Minimum = 0 and maximum=11. Higher scores indicate worse outcome.
