Effect of the Transcranial Direct Current Stimulation (tDCS) on Dependent Smoking People (TabaSCo)

August 16, 2016 updated by: Centre Hospitalier Universitaire de Besancon

Evaluation de l'Effet de la Stimulation Transcranienne en Courant Continu Chez Les Personnes Tabagiques dépendantes

The purpose of this study is to evaluate the effect of 10 sessions of anodal transcranial Direct Current Stimulation (tDCS - 1 mA) applied to left vs right CDLPF of tobacco-dependent subjects compared to the application of a placebo tDCS (sham procedure) on the craving, which is evaluated by the item 1 of Fagerström test between day 1 and day 10. Craving is also evaluated 1 month post-treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Tobacco is the second leading cause of death worldwide. It is currently responsible for the death of one in 10 adults (about 5 million deaths per year) and it is the fourth disease risk factor in the world. Many methods to quit smoking are available but in all cases, relapse is a common phenomena. The main risk factor for relapse is craving. So, acting on the craving seems essential to modulate tobacco consumption. Many functional neuroimaging studies have established a neuroanatomical substrate for craving process, in particularly dorsolateral prefrontal cortex (DLPFC), accessible par neuromodulation.

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.

Ages Eligible for Study

20 years to 60 years (ADULT)

Accepts Healthy Volunteers

Yes

Intervention / Treatment

ACTIVE_COMPARATOR: anodal tDCS on left DLPFC (F3)
tDCS is a non-invasive neuromodulation method, which delivers a constant current of low intensity (1 mA) during 30 min for 10 sessions. Anode is placed on the scalp facing on left DLPFC and cathode on right DLPFC.
Device: transcranial Direct Current Stimulation (tDCS)
After locating the stimulation areas, treatment will be delivered during 30-minute session. Treatment will be occur 1 session per day during 10 days (5 days per week during 2 successive weeks). Subjects will be monitored during tDCS for any side effects or adverse events.
Other Names:
  • EldithDC-NeuroConn Stimulator (NeuroConn Gmbh, Germany)
SHAM_COMPARATOR: sham tDCS on left DLPFC (F3)
tDCS differs from active tDCS by the interruption of stimulation after 15 sec and reactivation of the stimulation 15 sec before the end of the session (30 min - 10 sessions). Anode is placed on the scalp facing on left DLPFC and cathode on right DLPFC.
