Biomira Inc. announced the signing of amended and restated collaboration and supply agreements related to Stimuvax with Merck KGaA of Darmstadt, Germany. The amended agreements restructure the agreements originally signed in 2001, and are based upon the letter of intent signed in January 2006.

Stimuvax is an innovative investigational therapeutic cancer vaccine designed to induce an immune response to cancer cells that express MUC1, a protein antigen widely expressed on common cancers. Merck KGaA currently is conducting a global phase III trial of Stimuvax in patients with unresectable stage III non-small cell lung cancer (NSCLC).

Under the terms of the restated agreements, Merck will have world wide marketing rights to and will be entirely responsible for the further clinical development of Stimuvax. Biomira is entitled to development and sales-based milestone payments and a royalty on net sales. Biomira retains responsibility for the manufacture of Stimuvax, including process development and scale-up for commercial manufacturing. Merck will exclusively purchase Stimuvax from Biomira; with respect to purchases for commercial sales, the purchase price will be subtracted from Biomira's royalty. The restated agreements provide Biomira with revised payments based on certain milestones related to manufacturing scale-up and process transfer. Biomira also will receive a payment of US $2.5 million upon clearance of the transaction with the US anti-trust authorities.

"We are pleased to conclude these revised agreements with Merck, enhancing our relationship for this exciting product," said Dr Robert L Kirkman, MD, president and CEO of Biomira. "Given the significant clinical and commercial potential for Stimuvax, we believe that Merck KGaA's expertise and resources in global clinical development, sales and marketing will help to bring this innovative vaccine to as many patients as possible. Merck KGaA has demonstrated its ability to bring important new cancer therapies to market, and we believe this collaboration will enable robust and efficient development of Stimuvax in NSCLC and, potentially, several additional cancer indications."
