( Chapel Hill N.C. March 6 2007-Pozen...)Pozen Announces Positive Outcome for PA 325,Health

Chapel Hill, N.C., March 6, 2007-Pozen Inc. (NASDAQ: POZN), today announced top-line results of its "Safer Aspirin" PA 325 proof-of-concept study conducted during the fourth quarter of 2006. PA 325 is a patented formulation of 325mg of aspirin surrounded by a 20mg coating of an immediate release formulation of a proton pump inhibitor.

The PA 325, 28 day study, involved two groups of 40 subjects over the age of 50. Each subject was treated with either once a day commercially available enteric coated aspirin 325mg or PA 325. The primary endpoint was gastrointestinal damage as measured by the Lanza scoring system used in our previous PN studies. The results were highly significant with 10 percent of the PA group having Lanza 3 or 4 gastrointestinal damage, whereas 57.5percent of the enteric coated aspirin group had this level of gastrointestinal damage. Furthermore, no ulcers were seen in the PA group, while 20 percent of subjects in the enteric coated aspirin 325mg group developed a gastric ulcer during the study. This difference was also statistically significant.

Dr. John R. Plachetka, chairman, president and chief executive officer stated, "The data from this first clinical study with PA 325 is very encouraging."
