Clinical Trials for Memantine Hydrochloride

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00000867 A Study to Evaluate the Use of Memantine In Combination With Anti-HIV Drugs to Treat AIDS Dementia Complex (ADC) Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 1996-12-01 The purpose of this study is to determine the safety and effectiveness of memantine, an experimental drug, in improving AIDS dementia complex (ADC). The symptoms of ADC can be improved with zidovudine (ZDV). However, ZDV therapy has been associated with significant toxicities, and the effectiveness of ZDV seems to decrease during the second and third years of therapy. The effectiveness of other antiretroviral drugs as treatment for ADC is not known, so it is important to explore alternative therapies.
NCT00001344 Dextromethorphan Versus Placebo for Neuropathic Pain Completed National Institute of Dental and Craniofacial Research (NIDCR) Phase 2 1993-03-01 In our current clinical trial, we are comparing the effects of two NMDA receptor antagonists to placebo in patients with painful distal symmetrical diabetic neuropathy or post-herpetic neuralgia. The treatments in this three-period crossover study are dextromethorphan, up to 920 mg/day (about 8 times the antitussive dose), memantine, 30-50 mg/day, and placebo. Memantine is an NMDA antagonist used in Europe to treat Parkinson's disease and Alzheimer's disease. The underlying hypothesis, based on studies of painful neuropathies in animal models, is that neuropathic pain is caused largely by sensitization of central nervous system neurons caused by excitatory amino acid neurotransmitters, acting largely through NMDA receptors. A previous small trial of dextromethorphan suggested efficacy in diabetic neuropathy pain. The study requires one visit to the NIH outpatient Pain Research Clinic, and consists of three 9-week treatment periods. Patients who respond to one of the medications will be invited to participate in further controlled studies of the medication followed by up to several years of open-label treatment under continued observation.
NCT00040261 Clinical Trial of Memantine for Major Depression Completed National Institute of Mental Health (NIMH) Phase 3 2002-06-01 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.
