About Plecanatide

Plecanatide is Synergy’s lead guanylate cyclase-C (GC-C) agonist in development to treat patients with chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C). Plecanatide is a 16-amino-acid analog of the human gastrointestinal (GI) hormone, uroguanylin, a natural agonist for the intestinal GC-C receptor. Orally administered plecanatide mimics uroguanylin’s functions by binding to and activating the GC-C receptor to stimulate fluid secretion and transit required for normal digestion. Synergy has successfully completed a phase 2b trial of plecanatide with CIC patients and is currently enrolling patients into its pivotal phase 3 CIC program.
