Alcoholism Clinical Trial
Official title:
Quetiapine vs. Placebo in Alcohol Relapse Prevention - a Pilot Study
Due to Quetiapine's particulars and the promising receptor profile, we want to examine the
efficacy concerning relapse prevention of alcoholics suffering from persisting craving
and/or affective symptoms (persisting sleep disorder, persisting excitement, persisting
depressive symptoms, persisting anxiety symptoms) in comparison to matching placebo in a
double-blind pilot study.
We further want to compare the course of the above mentioned craving and affective symptoms
under medication with quetiapine / matching placebo.

Only methods with a Pearl-index lower than 1% are regarded as acceptable such as hormonal contraception, surgical sterilization, bilateral ovarectomy, and postmenopause (WHO definition: natural menopause retrospectively for at least one year amenorrhoe) without hormonal replacement therapy within the past 5 months. Exclusion Criteria: - Patients suffering from psychotic diseases and/or depression with psychotic symptoms and/or demented patients, patients with longlasting continous treatment with psychotropic drugs. - Known substance abuse other than alcohol or nicotine (except dependence in full remission) as defined by DSM-IV criteria. Patients with a positive urine toxicology screen will be excluded only if they satisfy the DSM-IV criteria for abuse or dependence. - Hepatitis (GGT or AST three times above normal range). - An absolute neutrophil count (ANC) of = 1.5 x 109 per liter. - A patient with Diabetes Mellitus (DM) fulfilling one of the following criteria: unstable DM defined as enrollment glycosylated hemoglobin (HbA1c)>8.5 %; patients admitted to hospital for treatment of DM or DM related illness in past 12 weeks; patients not under physicians care for DM; physicians responsible for patient´s DM care has not indicated that patient´s DM is controlled; physician responsible for patient´s DM care has not approved patient´s participation in the study; patient has not been on the same dose of oral hypoglycemic drug(s) and/or diet for the 4 weeks prior to randomization. [For thiazolidinediones (glitazones) this period should not be less than 8 weeks]; patients taking insulin whose daily dose on one occasion in the past 4 weeks has been more than 10% above or below their mean dose in the preceding 4 weeks. Note: If a diabetic patient meets one of these criteria, the patient is to be excluded even if the treating physician believes that the patient is stable and can participate in the study. Evidence of clinical relevant disease or clinical finding that is unstable or that, in the opinion of the investigator, would be negatively affected by study medication or that would affect study medication. - Patients who, in the investigator's judgment, pose a current serious suicidal risk or have made a suicide attempt within the past 6 months. - Restricted or complete legal incapacity. - Additional psychotherapy 1 month prior to randomisation or during participation in the study. - History of idiopathic orthostatic hypotension, or condition that would predispose to hypotension (e.g. dehydration, hypovolemia). - Risk of transmitting human immunodeficiency virus (HIV) or hepatitis B, C, via blood or other body fluids (as judged by the investigator). Positive HIV-serology in the screening visit. - Known regular treatment with Quetiapine prior to randomisation. - Hypersensitivity to Quetiapine or other constituents of the investigational product. - Simultaneous intake of Cytochrome-P-450-3A4- inducers or inhibitors: Use of drugs that induce or inhibit the hepatic metabolizing cytochrome 3A4 enzymes within 2 weeks prior to randomization or during the study period, e.g. the inducers: carbamazepine, phenytoin, barbiturates, rifampicin, rifabutin, glucocorticoids, thioridazine and St. Johns wort, and e.g. the inhibitors: HIV-protease-inhibitors, antimycotics of the azole type (e.g. ketoconazole (except for topical use), itroconazole, fluconazole), erythromycin, clarithromycin, fluvoxamine, nefazodone, troleandomycin, indinavir, nelfinavir, ritonavir, and saquinavir - Female patients who are pregnant or are lactating.
