Therapeutic Platform

CS-0003 is a first-in-class, Mucosal-Immune Modulator (MIM) therapeutic, that buffers the GI tract to prevent infections and reduce inflammation.

CS-0003: First-in-Class Upstream GI Therapeutic

CS-0003 is a first-in-class Mucosal-Immune Modulator designed to stabilize the GI mucosal barrier,
suppress stress-induced bacterial virulence signaling, and support balanced mucosal-immune responses
upstream of inflammatory amplification.

The Problem

GI surgery can destabilize the mucosal environment. Changes in barrier integrity and nutrient availability
may activate bacterial virulence pathways and increase infection risk.

Our Approach

Molecular structure of CS-0003

CS-0003 is a gut-directed therapeutic designed to act locally at the GI mucosal interface and counter phosphate-responsive virulence signaling.

  • Stabilize the barrier
  • Suppress stress-induced bacterial virulence signaling
  • Support mucosal-immune balance


Lead Indication
Prevention of GI Surgical Site Infection in High-Risk GI Surgery. CS-0003 is not being developed to treat established GI-SSI.

Broader MIM Opportunity
Potential expansion opportunities include inflammatory bowel disease, anastomotic leak, recurrent C. difficile infection, sepsis, colon cancer recurrence, and chemotherapy-related GI toxicities.

32 Bioscience's innovative approach redefines infection prevention, paving the way for safer, more effective surgical recovery.
