NCT00150839

Brief Summary

The proposed study is a randomized, placebo-controlled, double-blind trial to evaluate the safety and efficacy of antidepressant combination for the treatment of depression. Depressive disorder is one of the most common human diseases with a high burden for every patient, her/his family, health care system and society as a whole. Actual treatment concepts of depressive disorders include pharmacologic, biologic (e.g. electroconvulsive therapy, light therapy) and psychologic therapy. Even though effective therapeutic options are at hand, therapy needs time. It is often not possible to reach full remission of the disease and 10-25% of patients suffering from depression are regarded as "treatment-resistant". In treatment resistant depression, the use of a combination of antidepressive drugs is considered safe and effective. However, at present no data exist concerning the use of drug combination as primary therapeutic option. The aim of the study is to examine the hypothesis, that significantly more patients achieve full remission of depressive symptoms when treated with the combination of two antidepressants and as a secondary hypothesis, that patients receiving a drug combination will achieve remission faster than patients treated with monotherapy. To test these hypotheses, a two group parallel design is used comparing the efficacy and safety of mirtazapine in combination with venlafaxine or placebo.
