Targeted Therapeutics that Address Unmet Medical Needs

Inflammatory Bowel Disease (IBD) is complex and heterogeneous. A ‘one-size-fits-all’ standardized treatment may not be effective for many patients. In fact, 75% of the 2 million patients in the US who have IBD are refractory to first line biologic therapy¹.

Prometheus Biosciences is pioneering a precision medicine approach for the treatment of IBD. We merge access to hundreds of thousands of patient samples with advances in machine learning and data mining tools to understand the link between patients’ symptoms and disease-driving biomarkers. We use these breakthroughs to identify novel therapeutic targets and diagnostic tests to address the unmet medical needs.

Core Research Principles

The target is a true driver of disease in a defined IBD sub-phenotype

We can develop a selective medicine that has best-in-class potential

We can identify pathway-specific enrichment biomarkers

We can pre-identify and enroll the appropriate patients

Allowing us to deliver drugs with

  • superior label claims, first-line use
  • an accelerated, efficient path to the clinical and market
