ABT-436 for Alcohol Dependence

February 15, 2017 updated by: National Institute on Alcohol Abuse and Alcoholism (NIAAA)

A Phase 2, Double-Blind, Randomized, Placebo Controlled Trial to Assess the Efficacy of ABT-436 for Alcohol Dependence

The primary efficacy endpoint examines the hypothesis that ABT-436 will decrease the weekly percentage of heavy drinking days during Study Weeks 2 through 12 (Days 8-84) as compared to placebo. A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men.

Detailed Description

Adrenocorticotropic hormone (ACTH) release from the pituitary gland via V1B stimulation is central to the hypothalamus-pituitary-adrenal (HPA) axis stress response (Carrasco & Van de Kar-2003, Herman & Cullinan-1997, Sapolsky et al-2000; Tsigos & Chrousos-2002). Chronic dysregulation of the HPA axis is common in major depressive disorder, anxiety disorders, and substance abuse disorders characterized by elevated AVP, increased responsiveness to AVP, as well as either increased or decreased overall HPA axis activity or responsiveness (Dinan & Scott-2005). HPA axis normalization via pituitary V1B antagonism is a mechanism for potential ABT-436 efficacy in these disorders (Schüle et al-2009). Limbic V1B antagonism in the brain may also contribute to efficacy (Roper et al-2011).

Alcohol dependence, or alcoholism, is characterized by a chronic relapsing course, in which alcohol-associated cues and stress are known relapse triggers (Brownell et al-1986, Heilig & Egli-2006, Sinha & Li-2007). Recent research suggests that neural systems mediating behavioral stress responses may offer useful targets for pharmacotherapy of alcoholism. In animal models, excessive alcohol consumption that results from a history of alcohol dependence is accompanied by increased behavioral sensitivity to stress (Heilig & Koob-2007). Preclinical studies have shown that V1B antagonists can attenuate reinstatement of heroin and alcohol self-administration, and block dependence-induced exaggeration of alcohol intake, in rats. V1B antagonists have also been shown to block stress-induced reinstatement of drug and alcohol seeking in ethanol dependent rats (Zhou-2011). For these reasons the NIAAA Clinical Investigations Group (NCIG) proposes to test ABT-436 in a Phase 2, proof of concept trial for the treatment of alcohol dependence.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Weekly Percentage of Heaving Drinking Days
Time Frame: Weeks 2-12

The primary objective of this study is to assess the efficacy of ABT-436 to reduce the weekly percentage of heavy drinking days (reduction in drinking) in subjects with alcohol dependence confirmed by DSM-IV-TR criteria. A "heavy drinking day" is 4 or more drinks per drinking day for women and 5 or more drinks per drinking day for men.

The outcome measure was averaged across weeks 2-12.
