Stellar Pharmaceuticals Inc. Enters Into a Partnership With Pfizer Canada Inc. to Promote Gelfoam(R) in Canada

MILTON, ONTARIO--(Marketwire -08/23/12)- Stellar Pharmaceuticals Inc. (“Stellar”) (SLXCF)(SLXCF)(SLXCF) today announced that it has signed an agreement granting Stellar the exclusive Canadian promotional rights for Gelfoam® from Pfizer Canada Inc. (“Pfizer”) (PFE).

Gelfoam® is a medical device approved in Canada and the United States for use in surgical procedures as a haemostatic agent, when control of capillary, venous, and arteriolar bleeding by pressure, ligature, and other conventional procedures is either ineffective or impractical. “Gelfoam® is an absorbable haemostatic device used in hospitals and surgical centres across Canada” noted Mr. Rob Harris, President & CEO of Stellar. “The addition of Gelfoam is another step forward as we expand our hospital, specialty care business, which is a target area of growth for Stellar.”

Under the terms of the promotional agreement (the “Agreement”), Stellar is granted the exclusive Canadian promotional rights to Gelfoam® by Pfizer. Throughout the term of the Agreement, Stellar will act on behalf of Pfizer in the promotion, sales and marketing of Gelfoam® to surgeons and other health care practitioners in Canada. Pfizer will continue to be responsible for all distribution, regulatory affairs and medical related activities.

Mr. Harris further commented, “Gelfoam® should benefit from the increased promotion planned by Stellar, as well as the complimentary presence of our recently announced Collatamp G® acquisition. In addition, we feel that our existing specialty care products, NeoVisc® and Uracyst®, should benefit from Stellar’s greatly enhanced presence in the hospital and specialty care markets. We are very excited about the growth potential from Gelfoam® and look forward to building a long-term partnership with Pfizer.”
