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 large multicenter clinical trial 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. More information is available at
