-Demonstrates progress executing strategy to advance at least three new medicines addressing significant unmet needs into later-stage development by 2017/2018-
CAMBRIDGE, MA, USA I March 23, 2016 I Ironwood Pharmaceuticals, Inc. (IRWD) today announced that it initiated a Phase IIb clinical trial of IW-3718 in patients with refractory gastroesophageal reflux disease (GERD). Refractory GERD is a chronic condition in which patients continue to suffer from symptoms such as heartburn and regurgitation despite receiving treatment with a proton pump inhibitor (PPI). Data from this trial are expected in 2017.
“There is a significant unmet medical need among the estimated 10 million patients in the U.S. with refractory GERD,” said Mark Currie, Ph.D., chief scientific officer and president of research and development at Ironwood. “For these patients, PPIs are not enough to control their heartburn and regurgitation. They continue to suffer from frequent and bothersome symptoms, and there is a dearth of approved prescription medicines for this condition. For these reasons, the advancement of IW-3718 is a top priority for Ironwood.”
The randomized, double-blind, placebo-controlled, dose-ranging Phase IIb clinical trial is designed to evaluate the safety, efficacy, and dose-response relationship of IW-3718. The trial is expected to enroll approximately 260 adult patients who have been diagnosed with GERD and report experiencing heartburn or regurgitation at least four days per week during the previous eight weeks despite ongoing PPI treatment. The study design calls for eligible patients to continue taking their daily PPI therapy and to be randomized to receive additional treatment with placebo or one of three doses of IW-3718, twice-daily for eight weeks. The primary efficacy endpoint is change from baseline in heartburn severity.
Ironwood previously reported positive data from its randomized, double-blind, placebo-controlled Phase IIa study of IW-3718 for refractory GERD. Data from that study showed that IW-3718 improved heartburn severity in the intent-to-treat population. IW-3718 was generally well-tolerated with the most common adverse event being constipation.
About Refractory Gastroesophageal Reflux Disease
An estimated 45 million Americans have gastroesophageal reflux disease (GERD), an estimated 10 million of whom are thought to suffer from the refractory form of the condition, meaning they continue to experience symptoms such as heartburn and regurgitation despite receiving the current standard of care treatment with a proton pump inhibitor (PPI). While PPIs suppress production of stomach acid, research suggests reflux of bile from the intestine into the stomach and esophagus may play a role in the ongoing symptoms of refractory GERD. There are few FDA-approved treatment options for these patients. If left untreated, refractory GERD can lead to serious complications including Barrett’s esophagus and, in rare instances, esophageal cancer.
About IW-3718
IW-3718 is a novel, investigational gastric retentive formulation of a bile acid sequestrant, developed by Ironwood using the proprietary Acuform® drug delivery technology licensed from Depomed, Inc. IW-3718 is designed to remain in the stomach and duodenum (upper small intestine) over an extended period of time and to work in combination with a PPI to reduce the detrimental effects of bile and acid on the esophagus.
