Study Summary
The purpose of this study is to determine the safety and effectiveness of the drug memantine for treating major depression. Major depression is a serious public health concern that contributes to significant morbidity and mortality. Despite the availability of a wide range of antidepressant drugs, a proportion of patients with major depression fail to respond to first-line antidepressant treatment, despite adequate dosage, duration, and compliance. Recent studies suggest that the glutamatergic system may play a role in the pathophysiology and treatment of depression. Memantine and other agents which reduce glutamatergic neurotransmission may represent a novel class of antidepressants. The study consists of three phases. In Phase 1, participants will be tapered off all psychiatric medications over a 2-week washout period. In Phase 2, participants will be randomly assigned to receive either memantine or placebo (an inactive pill) three times a day for 8 weeks. Participants who do not respond to the treatment after 8 weeks will be taken off the study and offered standard treatment. Weekly psychiatric evaluations will evaluate treatment response. During Phase 2, participants who respond well to treatment will enter Phase 3, a 16-week continuation phase of either memantine or placebo. Interviews will be conducted every other week in the first month , then monthly thereafter. Participants will have a physical examination, neuropsychological tests, and eye blink tests at baseline and at the end of the study. Pulse, blood pressure, and blood samples will be taken throughout the study. Participants will undergo an electrocardiogram as well as positron emission tomography (PET) and magnetic resonance imaging (MRI) scans of the brain.
