About Synergy Pharmaceuticals, Inc.

Synergy is a biopharmaceutical company focused on the development of new drugs to treat gastrointestinal disorders and diseases. Synergy's lead proprietary drug candidate, plecanatide, is a synthetic analog of the human gastrointestinal hormone uroguanylin, and functions by activating the guanylate cyclase-C (GC-C) receptor on epithelial cells of the GI tract. Synergy completed a positive Phase I study of plecanatide in healthy volunteers, and positive Phase IIa and Phase IIb/III clinical trials in patients with chronic idiopathic constipation (CIC). Synergy is also developing plecanatide for the treatment of constipation-predominant irritable bowel syndrome (IBS-C), having initiated the first trial in IBS-C patients in late 2012. Synergy's second GC-C agonist, SP-333, is in clinical development to treat inflammatory bowel diseases, and has recently completed its first Phase I trial in healthy volunteers.

About Plecanatide

Plecanatide is a member of a new class of essentially non-systemic drugs, referred to as guanylate cyclase-C (GC-C) agonists, which are currently in development to treat CIC and IBS-C. Plecanatide is a synthetic analog of uroguanylin, a natriuretic hormone that regulates ion and fluid transport in the GI tract. Orally-administered plecanatide binds to and activates GC-C receptors 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. Activation of the GC-C receptor pathway is believed to facilitate bowel movement as well as producing other beneficial physiological responses including improvement in abdominal pain and inflammation. In animal models, oral administration of plecanatide promotes intestinal secretion and also ameliorates GI inflammation.
