Jacob, Ph.D., Chairman and CEO of Synergy Pharmaceuticals. “We are fortunate to have Paul join us and look forward to his contributions as we quickly advance plecanatide into phase 3 registration trials for IBS-C and prepare for a CIC NDA filing next year.”  “I am excited to be joining Synergy at such a critical stage of development,” said Dr. Eng. “Plecanatide has already demonstrated excellent clinical potential for treating IBS-C and CIC patients in phase 2 trials and I look forward to further establishing plecanatide’s efficacy and safety profile in pivotal phase 3 trials.”  Prior to joining Synergy, Dr. Eng was Director of Gastroenterology Clinical Development at Forest Laboratories, Inc., where he was chiefly responsible as study director for the successful pivotal phase 3 clinical trials that led to NDA and drug approval for treatment of CIC and IBS-C. Dr. Eng has a considerable record of achievement in clinical development and medical affairs, with positions at American Home Products (Wyeth) and Life Medical Sciences prior to joining Forest Laboratories in 2001. Dr. Eng holds a Ph.D., Immunology, M.S., Human Genetics and B.S., Physiology from Rutgers University.  About Plecanatide  Plecanatide is Synergy’s lead uroguanylin analog in late-stage clinical development to treat patients with CIC and IBS-C. Uroguanylin is a natural gastrointestinal (GI) hormone produced by humans in the small intestine and plays a key role in regulating the normal functioning of the digestive tract through its activity on the guanylate cyclase-C (GC-C) receptor. The GC-C receptor is known to be a primary source for stimulating a variety of beneficial physiological responses. Orally administered plecanatide mimics uroguanylin's functions by binding to and activating the GC-C receptor to stimulate fluid and ion transit required for normal bowel function. Plecanatide is structured identical to the natural hormone with one key amino acid substitution, resulting in a more potent and heat-stable analog and a binding constant eight times that of uroguanylin. Synergy has successfully completed a phase 2b trial of plecanatide in 951 patients with CIC and is currently enrolling patients in two pivotal phase 3 CIC trials. The company also recently announced positive top-line data results from a phase 2b dose-ranging study with plecanatide in patients with IBS-C.  About Synergy Pharmaceuticals  Synergy Pharmaceuticals (NASDAQ: SGYP) is a biopharmaceutical company focused on the development of novel therapies based on the natural human hormone, uroguanylin, to treat GI diseases and disorders. Synergy has created two unique analogs of uroguanylin – plecanatide and SP-333 – designed to mimic the natural hormone’s activity on the GC-C receptor and target a variety of GI conditions. SP-333 is currently in phase 2 development for opioid-induced constipation and is also being explored for ulcerative colitis. For more information, please visit www.synergypharma.com.
