Cornerstone BioPharma, Inc. and Athlon Pharmaceuticals Sign Co-Promotion Agreement

Cary, NC, June 06, 2006 --( Cornerstone BioPharma™, the Triangle-based specialty pharmaceutical company currently focused on the development and commercialization of niche prescription medications in the respiratory arena, today announced the company has signed a co-promotion agreement with Athlon Pharmaceuticals (Athlon). This agreement names Athlon as a partner in the promotion of Balacet 325™, a mild-to-moderate pain medication.

Balacet 325 was approved by the Food and Drug Administration in May 2005 and has since been promoted to pain specialists and primary care providers by Cornerstone BioPharma’s sales force. Commencing immediately, the Athlon sales force will co-promote Balacet 325, significantly increasing awareness, promotional efforts and reach of the medication. This partnership represents a significant expansion into the $14 billion U.S. pain market and will serve to increase the recognition of Balacet 325 among healthcare providers.

Commenting on the agreement, Athlon President Jeff Mason said, “We are very excited to be partnering with Cornerstone. The market demand for pain medications with lower levels of acetaminophen such as Balacet 325 is growing and will only continue to do so. Including Balacet 325 in our pain line will further strengthen Athlon's position in the specialty area of pain management."

“The strategic value of this partnership for Balacet 325 quickly became clear during our discussions with Athlon,” said Craig Collard, CEO of Cornerstone BioPharma. "Athlon’s experienced pain sales force is deeply entrenched in the market and will allow us to reach new marketplaces and increase our overall market share."

In March 2006 Cornerstone BioPharma announced a co-promotion agreement with ASCEND Therapeutics naming the company a partner in the promotion of Balacet 325. Since that announcement, the ASCEND sales force has co-promoted Balacet 325 with a focus on obstetrics and gynecology healthcare providers.
