Pozen Expects to Submit Revised Response to Trexima Approvable Letter by Year End

CHAPEL HILL, N.C., December 13, 2006 - POZEN Inc. announced today that the U.S. Food and Drug Administration (FDA) has completed its initial review of POZEN's response to the June 8, 2006 Approvable Letter for Trexima and has determined the response is not yet complete. The FDA has requested additional analyses and supporting information relating to the data submitted in the November response.

Provision of the additional information will allow the FDA to determine the comparability of the new data submitted in November to that contained within the original Trexima NDA and to more fully assess the relative safety profile of Trexima. POZEN expects to prepare and submit the revised response before year end.

Dr. Marshall Reese, executive vice president, product development of POZEN stated, "We appreciate this additional guidance from the FDA with respect to the information to be included in our complete response. Although there is no certainty that these revisions, coupled with the original data, will lead to the approval of the Trexima NDA, we continue to believe that the data for Trexima demonstrate superior efficacy and a safety profile comparable to sumatriptan."
