Brooklyn Health

AI-driven eCOA platform for CNS trials

Overview

Brooklyn Health builds Willis, an electronic Clinical Outcome Assessment (eCOA) platform for CNS clinical trials that uses AI and digital phenotyping to analyze clinical interviews by measuring spoken words, facial expressions, body language, and vocal tone to track symptoms over time. The platform is organized into OpenWillis (open-source phenotyping methods), WillisPipeline (converts behavioral data into clinical measures), and WillisAPI (integration with other digital health tools). This setup helps pharma teams use validated, standardized measures instead of creating their own, enabling more objective trial data. The company aims to improve the accuracy of treatment evaluation in CNS trials and reduce trial failures by better separating drug effects from placebo.
