Memantine Augmentation of Targeted Cognitive Training in Schizophrenia

University of California, San Diego·interventional·Posted Apr 23, 2021·Updated May 18, 2026

In Brief

A Phase 3 clinical trial evaluating Memantine and Placebo for Schizophrenia and Schizoaffective Disorder. Completed, enrolled 62 participants across 1 site.

Detailed Summary

Treatment of schizophrenia currently includes antipsychotic medications and cognitive therapies which improve some symptoms, but do not sufficiently restore cognitive functioning or reduce psychosocial disability. We hypothesize that medications that specifically target sensory information processing deficits, rather than psychotic symptoms per se, will significantly enhance the benefits of a sensory-based targeted cognitive training (TCT) intervention in patients with schizophrenia. We will complete a randomized, double-blind clinical trial to: 1) confirm that the drug memantine augments TCT learning; 2) determine whether memantine enhances the clinical benefits from a full 30 session course of TCT vs. TCT plus placebo in antipsychotic- medicated schizophrenia patients, and 3) determine if memantine's enhancement of TCT is most effective in biomarker-defined subgroups of patients.
