The ERP Biomarker Qualification Consortium, LLC

This is a Phase 0, Double-Blind, Randomized, Placebo-Controlled, Crossover Study to assess the changes in ERP Biomarkers in Healthy Volunteers before and after administration of a sub-anesthetic dose of ketamine. Primary objectives are to quantify the effect size of ketamine-induced changes on MMN from a duration-deviant auditory oddball ERP test and to quantify the variability of ketamine-induced changes on MMN from a duration-deviant auditory oddball ERP test.

This is an observational, non-interventional study that will recruit Healthy Volunteers (HV) and subjects with clinically confirmed Schizophrenia (SZ). The purpose of this study is to establish the mean and variance across the HV and SZ cohorts, sites, and repeated tests of the electroencephalogram(EEG)/Event-related potentials (ERP) measures.
