POZEN Provides Update on Its PA Program and Results of Its Type A Meeting with the FDA

,a pharmaceutical company committed to transforming medicine that transforms lives, today announced the results of the Company’s Type A meeting with the U.S. Food and Drug Administration (FDA) regarding issues related to POZEN’s planned New Drug Application (NDA) for PA32540 and PA8140 (high and lower dose versions of 325 mg aspirin delayed-release and 40 mg omeprazole immediate-release, and 81 mg aspirin delayed-release and 40 mg omeprazole immediate-release, respectively) for the secondary prevention of cardio - and cerebrovascular events and to reduce the risk of gastric ulcers in patients at risk of aspirin induced gastric ulcers.

The FDA confirmed that, although the Agency believes bioequivalence of PA32540 to enteric-coated Ecotrin 325 mg, the Reference Listed Drug (RLD), was not strictly established in Study 115 according to the predetermined criteria, the results from Study 115, together with additional information that will be submitted in the NDA, constitutes sufficient data to support the establishment of a bridge to Ecotrin 325 mg under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act. The FDA will make a final determination during the NDA review. Based on our discussions with the FDA, POZEN does not plan to conduct any further bioequivalence studies with PA32540.

The FDA also indicated that a similar strategy to bridge to the RLD under Section 505(b)(2), inclusive of a new, single pharmacokinetic study, could be utilized for a low dose version of PA32540 (currently, PA8140). POZEN plans to conduct this study with the low dose version against the RLD, EC-Ecotrin 81 mg, and submit these results and other supporting data in the NDA. POZEN also confirmed with the FDA that no additional clinical data would be submitted for a lower dose version and, in particular, that no Phase 3 program will be conducted.

In addition, the FDA has confirmed its preference to have both PA32540 and a lower dose version available in the market so that physicians can have both a low and high dose option available, and agreed that, if both dosage strengths were included in the NDA and subsequently approved, the indications for both will be consistent with the full range of indications described in the current aspirin monograph.

Finally, the FDA has agreed to provide additional feedback with respect to certain aspects of the proposed content of the NDA as it relates to the lower dose formulation. Once that is received, the Company will provide a final update on the timing of the NDA submission, but a first half 2013 NDA submission is likely.

“We are pleased with the high level of cooperation we have received from the FDA and appreciate all of the time spent with us to help bring both doses of this promising product concept to the NDA stage. We will continue to work closely with the Agency on the final content of the NDA with the expectation that all remaining details will be finalized by the end of the year,” said John R. Plachetka, Chairman, President and Chief Executive Officer of POZEN Inc. “Since most patients take the lower dose of cardioprotective aspirin, we believe the opportunity to include both doses in the NDA in such an efficient manner and with only a short delay in submission timing greatly improves both the clinical and the commercial value of the PA franchise. We are excited about the prospect of offering both doses to practicing clinicians and patients, and we plan to talk with potential partners about these developments as soon as possible.”

We currently anticipate cash and short-term investments to be in line with our original guidance of $85 million at the end of 2012.

POZEN will host a webcast to further discuss these outcomes on Friday, August 24, 2012 at 9:00 a.m. (ET). The webcast can be accessed live and will be available for replay at .

POZEN is creating a portfolio of integrated aspirin therapies - the PA product platform. 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.
