Combination of NMDA-enhancing and Anti-inflammatory Treatments for Ultra-resistant Schizophrenia
Source: ClinicalTrials.gov · Last updated 24 Mar 2026
Brief summary (registry, in English)
Previous study found that some NMDA-enhancing agent was able to augment efficacy of clozapine for clinical symptoms but not cognitive function in the treatment of ultra-resistant schizophrenia. In addition, several drugs with anti-inflammatory properties have been tested in clinical trials for the treatment of schizophrenia. Whether a drug with anti-inflammatory property can strengthen the efficacy of an NMDA-enhancer (NMDAE) in the treatment of ultra-resistant schizophrenia remains unknown.
