Synergy Pharmaceuticals Completes Patient Enrollment for its SP-333 Phase 2 Trial in Patients with Opioid-Induced Constipation

NEW YORK --(Business Wire)--

Synergy (News - Alert) Pharmaceuticals Inc. (NASDAQ:SGYP) today announced that it has successfully completed patient enrollment for its phase 2 trial of SP-333, Synergy's next-generation uroguanylin analog, in patients with opioid-induced constipation (OIC).

The multi-center, randomized, double-blind clinical trial is designed to compare a 4-week dose-ranging regimen of once-daily oral SP-333 (1.0 mg, 3.0 mg and 6.0 mg) against placebo in patients taking opioid analgesics for chronic, non-cancer pain for at least three months. The study will evaluate approximately 260 patients with OIC who have less than 3 spontaneous bowel movements (SBMs) per week and who experience constipation related symptoms. The primary endpoint of the study is mean change from baseline in the number of SBMs during Week 4 of the Treatment Period.

Synergy plans to release top-line data from this trial in the fourth quarter of this year. For more information, please visit http://clinicaltrials.gov/ct2/show/NCT01983306?term=sp-333&rank=1

About Synergy Pharmaceuticals

Synergy Pharmaceuticals (NASDAQ:SGYP) is a biopharmaceutical company focused on the development of novel therapies based on the naturally occurring 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 intestinal guanylate cyclase-C (GC-C) receptor and target a variety of GI conditions.
