About Prometheus Biosciences

Prometheus Biosciences, Inc. is a clinical-stage biotechnology company pioneering a precision medicine approach for the discovery, development, and commercialization of novel therapeutic and companion diagnostic products for the treatment of immune-mediated diseases. The Company’s precision medicine platform, Prometheus360TM, combines proprietary machine learning-based analytical approaches with one of the world’s largest gastrointestinal bioinformatics databases to identify novel therapeutic targets and develop therapeutic candidates to engage those targets.

The Company’s lead candidate, PRA023, is an IgG1 humanized monoclonal antibody (mAb) for the treatment of immune-mediated diseases including Ulcerative colitis (UC), Crohn’s disease (CD), and the newly identified systemic sclerosis-associated interstitial lung disease (SSc-ILD). The Company is currently conducting a Phase 2 trial in UC patients and a Phase 2a trial in CD patients, each utilizing a proprietary genetic-based companion diagnostic designed to identify patients who are predisposed to increased expression of TL1A and therefore potentially more likely to respond to PRA023. The company also plans to initiate a Phase 2 clinical trial for PRA023 in SSc-ILD in the first quarter of 2022.
