Development of Novel Therapeutics for Chronic Inflammation by Leveraging Innate Lymphocyte Populations

Principal Investigator: 

Gregory Sonnenberg, The Henry R. Erle, M.D.-Roberts Family Associate Professor of Medicine

Summary

  • Irritable Bowel Disease (IBD) involves chronic inflammation of intestinal tissue
  • Rising rates of IBD in the US and globally underscores the need for novel and effective therapeutics
  • Dr. Sonnenberg has been at the forefront of interrogating the function, regulation and therapeutic potential of tissue resident ILC3s, for mediating chronic intestinal inflammation
  • His work highlights a novel pathway that offers a potential new therapeutic target for treating chronic gut inflammation

Technical Overview

  • Group 3 innate lymphoid cells (ILC3s) are tissue resident cells that regulate immunity, inflammation, and tissue homeostasis
  • Tumor Necrosis Factor (TNF) drives chronic inflammation in Irritable Bowl Disease (IBD) and other chronic inflammatory diseases
  • ILC3s produce heparin-binding EGF-like growth factor (HB-EGF) which can protect intestinal epithelium from TNF-induced cell death
  • Pre-clinical studies of both acute intestinal inflammation and chronic intestinal inflammation demonstrate that HB-EGF was essential in reducing intestinal damage and inflammation
  • Patients with IBD have significantly fewer HB-EGF-producing
  • ILC3s in inflamed intestinal tissue compared to normal patients
  • Selective activation of the ILC3-HB-EGF pathway provides a novel therapeutic target for chronic intestinal inflammation

Market Opportunity

  • Disease market: Approximately 3 million Americans suffer from IBD with 70,000 new cases per year
  • IBD treatment market was approximately $8.6 billion in the US in 2020 with an expected CAGR of 3.8% over the next 10 years
  • TNF inhibitors have the market share of IBD therapeutics

Partnering Opportunity

Weill Cornell Medicine is seeking a strong industrial partner with whom to collaborate around a dedicated program in the Sonnenberg
lab aimed at developing new drugs to selectively activate ILC3s
