Alcohol Dependency clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Relapse Prevention in Alcohol Dependency by Transcranial Direct Current Stimulation Supported Cue Exposure Therapy

Start date: August 2014
Phase: N/A
Study type: Interventional

Relapse is a major risk in substance abuse disorders, which is closely related to craving for a substance, describing a strong urge for consumption. Cue-exposure therapy is an intervention aiming at the reduction of perceived craving by repeated confrontation. It is based on the assumption that craving drops after repeated exposure without the reinforcing experience elicited by consumption. In the present study, patients with alcohol dependency take part in nine cue-exposure training sessions. Each session consists of mood induction reflecting a high risk situation with subsequent in vivo confrontation with one's preferred alcoholic beverage followed by the training of coping strategies. During the cue-exposure, patients focus on perceiving automatic responses to alcohol-related cues. We hypothesize that especially patients exhibiting initially high reactions to such cues should profit from this intervention the most. The reactions are measured on a subjective (craving) and physiological level (hemodynamics of the prefrontal cortex, heart rate variability, electrodermal activity). Furthermore, we want to strengthen the expected training effects during the cue-exposure by an activating transcranial direct current stimulation of the dorsolateral prefrontal cortex, which has been shown to be hypoactive in substance abuse disorders. We investigate how the cue-exposure training affects the processing of alcoholic cues (cue-reactivity) and its relation to clinical symptoms of alcohol dependency.
