First patients at St. Joseph's Hospital and Medical Center implanted in EndoStim's LESS GERD clinical trial for gastroesophageal reflux disease (GERD)

GERD affects nearly 65 million people in the United States¹. It occurs when stomach acid or other stomach contents flow back into the esophagus, often caused by a weak valve, or sphincter, between the esophagus and the stomach called the lower esophageal sphincter (LES). Frequent and troublesome symptoms can include heartburn, regurgitation, sleep disruption, vocal impairment and respiratory complications. Most GERD symptoms are successfully treated with acid blocking medications such as proton pump inhibitors (PPI). However, nearly 30 percent of patients on PPI medication continue to suffer from symptoms. The traditional anti-reflux surgery is laparoscopic fundoplication surgery, a procedure in which the surgeon wraps the top of the stomach around the lower esophagus to reinforce the lower esophageal sphincter. While typically effective, fundoplication can cause significant side effects.

The LESS GERD trial will evaluate the safety and efficacy of the EndoStim Lower Esophageal Sphincter (LES) Stimulation System in patients with gastroesophageal reflux disease (GERD) who experience symptoms despite taking high-dose proton pump inhibitor (PPI) medications.

"GERD disrupts the lives of millions of Americans, and many continue to suffer from symptoms like heartburn and regurgitation even when taking PPI medications," commented Sumeet Mittal, MD, surgical director of the Esophageal & Foregut Program at St. Joseph's and a principal investigator in the study.

"I look forward to the results of the trial and am hopeful that EndoStim can help a significant population suffering from disruptive GERD symptoms," commented Ross Bremner, MD, director of the Norton Thoracic Institute at St. Joseph's and a sub-investigator in the study.

"We are excited to start the LESS GERD Clinical trial at St. Joseph's Hospital and Medical Center to generate evidence for a novel new treatment for Chronic GERD, an undertreated disease that is disrupting the lives of millions of patients worldwide," said Rohan Hoare, Ph.D., President and Chief Executive Officer of EndoStim. "Unlike many common treatment options that work to alleviate GERD symptoms, EndoStim targets the underlying pathophysiology of GERD with the potential to restore normal function to the lower esophageal sphincter (LES)."

About the Lower Esophageal Sphincter Stimulation for GERD (LESS GERD) Trial
The LESS GERD trial will examine the effects of the EndoStim LES Stimulation System on GERD outcomes such as: esophageal acid exposure; GERD symptoms (heartburn and regurgitation); ability to avoid dependence on PPI medications; and the effect on overall quality of life. A minimum of 110 subjects will be implanted with the EndoStim device. The study is open to GERD patients who are between the ages of 22 and 75; have been diagnosed with GERD; have taken daily PPI medication and whose GERD symptoms are not completely resolved or have side effects from the PPI; and have had no prior surgery involving the esophagus.
