Biomarker Predictors of Memantine Sensitivity in Patients With Alzheimer's Disease

"Phase 1 will test the acute effects of memantine (20 mg po) vs. placebo (PBO) on early auditory information processing measures in 32 carefully characterized patients with mild-to-moderate severity AD who are not currently taking AD medications. From this challenge test, a set of early auditory information processing memantine sensitivity measures will be derived for each patient. In Phase 2, all patients will begin an open-label trial of memantine, titrated to 10 mg bid, with outcome measures collected after 8, 16 and 24 weeks of treatment. Medication adjustments are not restricted, and response heterogeneity is anticipated."
