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 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). Detailed positive findings from a recently
completed 951 patient CIC clinical trial will be presented at a major
scientific meeting this year. Synergy is also developing plecanatide for the
treatment of irritable bowel syndrome with constipation (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 is currently in a Phase Ib trial in healthy volunteers having
recently completed a Phase Ia trial.
