U.S., Oct. 6 -- ClinicalTrials.gov registry received information related to the study (NCT07858175) titled 'Clinical Evaluation of a Novel DAB Chromogenic Tissue-Based Assay for Detecting Anti-GABABR Antibodies' on Sept. 18.
Brief Summary: This multicenter, blinded, cross-sectional study aims to evaluate the clinical performance of a novel DAB chromogenic tissue-based assay (TBA) for detecting anti-GABAB receptor (anti-GABABR) antibodies. A total of 300 participants will be enrolled across four groups: (a) 50 patients with anti-GABABR antibody-positive encephalitis; (b) 100 patients with suspected autoimmune encephalitis and negative anti-neuronal antibody cell-based assay (CBA); (c) 50 patients with non-autoimmune disease (Alzheimer's dis...
