About Synergy Pharmaceuticals Inc.

Synergy Pharmaceuticals is a biopharmaceutical company focused on the development of new drugs to treat patients with gastrointestinal (GI) diseases and disorders. Synergy's lead proprietary drug candidate, plecanatide, is a synthetic analog of the human GI hormone, uroguanylin, and functions by activating the guanylate cyclase-C (GC-C) receptor on epithelial cells of the GI tract. In early 2013, Synergy announced positive results from a large multicenter trial of plecanatide in patients with chronic idiopathic constipation (CIC) and recently completed an end-of-phase 2 meeting with the U.S. Food and Drug Administration (FDA) covering the registration program for plecanatide to treat CIC. The company plans to initiate the phase 3 registration trial for plecanatide in CIC this quarter. Synergy is also developing plecanatide for the treatment of irritable bowel syndrome with constipation (IBS-C), recently announcing that it had reached the halfway mark for total enrollment in a plecanatide phase 2b clinical trial in patients with IBS-C. Synergy’s second GC-C agonist, SP-333, is in clinical development to treat opioid-induced constipation and inflammatory bowel disease. SP-333 has completed a phase I study in healthy volunteers and will enter phase 2 trials for OIC in the fourth quarter of 2013. More information is available at www.synergypharma.com .
