About SP-304

SP-304 is a member of a new class of non-systemic drugs for treatment of chronic constipation (CC), irritable bowel syndrome with constipation (IBS-C) and other GI diseases. SP-304 is a synthetic analog of uroguanylin, a natriuretic hormone that regulates ion and fluid transport in the GI tract. Orally administered SP-304 binds to and activates guanylate cyclase C (GC-C) expressed on epithelial cells lining the GI mucosa, resulting in activation of the cystic fibrosis transmembrane conductance regulator (CFTR), and leading to augmented flow of chloride and water into the lumen of the gut, facilitating bowel movement. In animal models, oral administration of SP-304 promotes intestinal secretion as well as ameliorating gastrointestinal inflammation.
