Merck Serono, a division of Merck KGaA, announced that it has modified the license from Oncothyreon to include the right to manufacture Stimuvax (BLP25 liposome vaccine) and also has purchased current inventory and certain assets used for the manufacture of Stimuvax from Oncothyreon Inc. for a total amount of approximately US$13 million. Merck Serono already held the clinical development and commercialization rights for Stimuvax under license from Oncothyreon.
Stimuvax is a therapeutic vaccine in phase III clinical development for non-small cell lung cancer (NSCLC) and is the first investigational vaccine in unresectable stage III NSCLC to enter phase III clinical testing (the START study).
In conjunction with this transaction, EMD Serono Canada Inc., an affiliate of Merck KGaA, has assumed control of Oncothyreon's facility in Edmonton, Canada, which is primarily utilized for the manufacture and development of Stimuvax. Merck Serono now has responsibility for development of the commercial-scale manufacturing process. EMD Serono Canada intends to offer employment to the majority of Oncothyreon's 52 employees in Edmonton.
"Merck Serono's acquisition of manufacturing rights for Stimuvax reflects our confidence in its future role in the treatment of cancer and also our commitment to expanding our oncology portfolio so that we can continue to provide oncologists and patients with innovative treatment options," said Hanns-Eberhard Erle, executive vice president technical operations, Merck Serono, a division of Merck KGaA.
"In addition, with the Edmonton facility we are proud to be adding a group of experienced and dedicated individuals to our workforce who will form a vital arm of the team that supports the ongoing development of Stimuvax," Erle continued.
The transfer of Stimuvax manufacturing rights has required the license agreement between Merck Serono and Oncothyreon to be amended and restated. While potential payments upon achievement of certain milestones under the previous agreements between Merck Serono and Oncothyreon remain unchanged, the royalty rates payable to Oncothyreon on future net sales are reduced. While the previous agreements already included some limited manufacturing rights, the new agreement provides Merck Serono with the full rights.
"We believe that the license of manufacturing rights for Stimuvax to Merck Serono is in the best interest of the development of this product," said Robert L. Kirkman, M.D., president and chief executive officer of Oncothyreon. "Merck Serono will be able to bring its resources and manufacturing expertise to the development of a commercial manufacturing process for Stimuvax, which has become a key component of its oncology pipeline. At Oncothyreon we will be able to focus our resources on our proprietary pipeline of targeted small molecules in oncology."
Merck KGaA is investigating the use of Stimuvax (BLP25 Liposome Vaccine) in the treatment of NSCLC. The vaccine was granted fast-track status in September 2004 by the FDA. Merck obtained the exclusive worldwide licensing rights from Oncothyreon Inc., Bellevue, Washington, USA. Stimuvax is being developed in Europe by Merck KGaA and in the United States by its affiliate, EMD Serono Inc.
START is a multi-centre, randomized, double-blind, placebo-controlled study that will evaluate patients with documented unresectable stage IIIA or IIIB NSCLC who have had a response or stable disease after at least two cycles of platinum-based chemo-radiotherapy. The study will involve more than 1,300 patients in approximately 30 countries.
