NEW YORK, June 23, 2015 — Synergy Pharmaceuticals Inc. (NASDAQ:SGYP) announced today the initiation of the second of two pivotal phase 3 clinical trialsevaluating the efficacy and safety of two different plecanatide treatment doses (3.0 mg and 6.0 mg), taken as a tablet once-a-day, in patients with irritable bowel syndrome with constipation (IBS-C).
The phase 3 IBS-C program includes two randomized, 12-week, double-blind, placebo-controlled pivotal trials conducted in the United States and each trial is expected to enroll approximately 1050 adult patients with IBS-C. Patients with IBS-C are defined by Rome III Criteria as having a history of constipation and abdominal pain for at least 6 months, including hard or lumpy stools for 25% or more of defecations, loose or watery stools for 25% or less of defecations, and abdominal pain or discomfort for 3 days or more per month for the last 3 months. The primary efficacy endpoint for both trials is the percentage of patients who are Overall Responders during the 12 week treatment period. An Overall Responder, as defined by the FDA, is a patient who is a weekly responder (i.e. meets both the abdominal pain intensity reduction and stool frequency increase criteria in the same week) for at least 6 of the 12 treatment weeks.
Synergy initiated the first phase 3 IBS-C trial in December 2014. The phase 3 IBS-C program was designed to support regulatory submission in the US.
About Plecanatide
Plecanatide is Synergy’s lead uroguanylin analogue in late-stage clinical development to treat patients with chronic idiopathic constipation (CIC) and IBS-C. Uroguanylin is a naturally occurring gastrointestinal (GI) peptide produced by humans in the small intestine and plays a key role in regulating normal GI activity. Orally administered plecanatide is designed to mimic uroguanylin’s natural activity and regulate the movement of fluid required for normal digestion. Synergy recently announced positive top-line data results from the first of two pivotal phase 3 trials evaluating the efficacy and safety of plecanatide treatment in patients with CIC. The company plans to release results from the second phase 3 CIC trial in the third quarter of this year.
