POZEN Inc. and Sanofi US Mutually Agree to Terminate U.S. Partnership for PA8140/PA32540

FDA Provides Preliminary Approval for Tradename ‘YOSPRALA’ Pending Approval of the PA8140/PA32540 NDA

CHAPEL HILL, N.C.--(BUSINESS WIRE)--Dec. 1, 2014-- POZEN Inc. (NASDAQ: POZN), a pharmaceutical company committed to transforming medicine that transforms lives, today announced that it and Sanofi US have mutually agreed to terminate their agreement for commercialization of the investigational products, PA8140 and PA32540 effective November 29, 2014. As of the effective date of the termination, all licenses granted to Sanofi US will be terminated and all rights to the products will revert to POZEN.

Additionally, the proposed tradename for these products, YOSPRALA, was provisionally approved by the U.S. Food and Drug Administration (FDA) pending final approval of the New Drug Application (NDA). In the future, PA8140 will be referred to as YOSPRALA 81/40 (enteric-coated aspirin 81 mg/immediate release omeprazole 40 mg) and PA32540 (enteric-coated aspirin 325 mg/immediate release omeprazole 40 mg) will be referred to as YOSPRALA 325/40.

“Our goal at POZEN continues to be to maximize shareholder return. Management and the Board of Directors are taking this opportunity to evaluate all strategic options for YOSPRALA and POZEN,” said Dr. John Plachetka, Chairman, President and Chief Executive Officer. “As we continue to work with the FDA during these final weeks leading up to our December 30th PDUFA date, we are very happy with the current FDA-proposed package insert. With respect to how well YOSPRALA may perform in the marketplace, we believe that the clinical profile of the drug, as described in the current FDA-proposed package insert, will meet or exceed the assumptions we made when we started our development and evaluated the commercial potential for this product. Given that the target population for YOSPRALA could exceed 20 million patients in the US, we will be fully engaged in the near term evaluating strategic options available to the company.”

Two (2) phase 3 clinical studies randomized 1,049 subjects to either investigational YOSPRALA 325/40 (enteric-coated aspirin 325 mg/immediate release omeprazole 40 mg) or EC aspirin 325 mg for 6 months of treatment. Subjects taking YOSPRALA 325/40 reported 63 percent fewer (p<0.001) gastric ulcers than those taking 325 mg enteric-coated aspirin. In addition, patients taking YOSPRALA 325/40 reported 82% fewer (p<0.001) discontinuations due to pre-specified upper gastrointestinal (GI) adverse events than patients taking 325 mg enteric-coated aspirin. Major adverse cardiac events (MACE) were similar between treatment groups and occurred in 1.7% of subject on YOSPRALA 325/40 and 2.5% of subjects on enteric-coated aspirin 325 mg. Seventy-two percent (72%) of subjects on YOSPRALA 325/40 reported any adverse events compared to 85% of subjects on EC aspirin 325 mg. The most commonly reported adverse events with YOSPRALA 325/40 were gastritis, erosive gastritis, dyspepsia, duodenitis, nausea, esophagitis, diarrhea, gastric polyps, and non-cardiac chest pain.

About YOSPRALA (Formerly known as PA)

POZEN has created a portfolio of investigational integrated aspirin therapies - the YOSPRALA product platform. The products in the YOSPRALA portfolio are being developed with the goal of significantly reducing GI ulcers and other GI complications compared to taking enteric-coated or plain aspirin alone.

The first candidates are YOSPRALA 81/40, containing 81 mg of aspirin, and YOSPRALA 325/40, containing 325 mg of aspirin. Both products are a coordinated-delivery tablet combining immediate-release omeprazole (40 mg), a proton pump inhibitor, layered around a pH-sensitive coating of an aspirin core. This novel, patented product is intended for oral administration once a day and an indication is being sought for use for the secondary prevention of cardiovascular disease in patients at risk for aspirin-induced gastric ulcers.
