June 23, 2026 updated by: Prenosis, Inc.

Observational Biomarker Study for the Evaluation of Response and Validation of Endotypes in Acute Respiratory Distress Syndrome

The goal of this observational study is to establish a centralized ARDS biorepository of longitudinal biospecimens and harmonized clinical data, develop unsupervised, therapy-agnostic endotyping algorithms, and develop unsupervised, therapy-specific treatment-prediction algorithms over a 24 month period.
