In the combined data from the two trials, 85.1% of subjects on enteric-coated aspirin (325 mg) reported adverse events compared to 71.8% of subjects on PA32540. The most commonly reported adverse events with PA32540 and enteric-coated aspirin (325 mg) were of the GI tract and include dyspepsia (11.3% vs. 30.2%), erosive gastritis (11.5% vs. 26.3%), and gastritis (17.5% vs. 16.0%) respectively. The incidence and nature of adjudicated Major Adverse Cardiac Events (MACE) such as heart attacks was similar between the 2 treatment arms: 9 subjects (1.7%) on PA32540 experienced adjudicated MACE compared to 13 subjects (2.5%) on aspirin (325 mg). Please see the complete AHA poster, available at www.pozen.com, for more detail of the study results.“Aspirin is often recommended for the secondary prevention of cardiovascular events; however, it also can be a contributing factor to the development of gastric ulcers as well as abdominal discomfort (dyspepsia) and other troublesome upper GI tract symptoms,” said Dr. Jay L. Goldstein, Vice Chairman of the Department of Medicine, and Head of the Division of Gastroenterology at NorthShore University Health System as well as one of the authors of the studies. “In these two randomized trials, the use of the combination product PA32540 was associated with fewer gastric ulcers and a lower rate of dyspepsia and other upper GI tract symptoms than aspirin alone. With a reduction of these symptoms, patients can be provided the option of an overall better-tolerated therapy for ongoing secondary prevention of cardiovascular events.” The two Phase 3, double-blind, randomized, multicenter studies enrolled 1,049 subjects who were prescribed daily aspirin (325 mg) for greater than or equal to three months for secondary prevention of cardiovascular events. The primary endpoint was the cumulative observed incidence of gastric ulcers over six months. Secondary endpoints included cumulative incidence of gastric and duodenal ulcers, discontinuation due to pre-specified UGI adverse events and heartburn resolution. Subjects were randomly assigned to once-daily treatment with PA32540 or 325 mg of enteric-coated aspirin. Endoscopic assessments were performed at screening and at one, three and six months. Major adverse cardiac events were reviewed and adjudicated by an independent, blinded endpoint committee composed of Cardiologists.
Cardiovascular disease is the leading cause of death in the United States, and there are currently 24 million secondary prevention patients, most of whom are on a daily aspirin therapy. However, approximately 15 percent of people on low-dose aspirin are at risk for upper GI adverse events, and 12 percent discontinue or reduce intake due to these serious UGI side effects.Additional data from the two pivotal Phase 3 PA32540 trials recently were presented at the American College of Gastroenterology 2012 Annual Meeting.

The products in the PA portfolio are intended to significantly reduce GI ulcers and other GI complications compared to taking aspirin alone. The first candidates are PA32540, containing 325 mg of aspirin, and PA8140, containing 81 mg of aspirin. Both products are a coordinated-delivery tablet combining immediate-release omeprazole (40 mg), a proton pump inhibitor, layered around pH-sensitive aspirin. This novel, patented product is administered orally once a day and an indication will be sought for use for the secondary prevention of cardiovascular disease in patients at risk for aspirin-induced ulcers. About POZEN POZEN Inc. is a progressive pharmaceutical company that is transforming how the healthcare industry addresses unmet medical needs. By utilizing a unique in-source model and focusing on integrated therapies, POZEN has successfully developed and obtained FDA approval of two self-invented products in two years. Funded by these milestone/royalty streams, POZEN is now creating a portfolio of cost-effective, evidence based integrated aspirin therapies designed to enable the full power of aspirin by reducing its GI damage.
POZEN is currently seeking strategic partners to help maximize the opportunity for its portfolio assets.The Company's common stock is traded under the symbol “POZN” on The NASDAQ Global Market.
