Seattle Genetics and Millennium: The Takeda Oncology Company Announce Strategic Collaboration for Novel Late-Stage Lymphoma Program Brentuximab Vedotin (SGN-35)

Seattle Genetics to Receive $60 Million Upfront Payment and Retain Full Commercialization Rights to Brentuximab Vedotin in U.S. and Canada; Takeda Group to Commercialize in the Rest of the World

Seattle Genetics to Host Conference Call December 15, 2009 at 8:30 A.M. Eastern Time

BOTHELL, Wash. & CAMBRIDGE, Mass. & OSAKA, Japan--(HSMN NewsFeed)--Seattle Genetics, Inc. (Nasdaq: SGEN ) and Millennium: The Takeda Oncology Company with its parent company Takeda Pharmaceutical Company Limited (TSE: 4502 ) today jointly announced that Seattle Genetics and Millennium have entered into an agreement to globally develop and commercialize brentuximab vedotin (SGN-35). Brentuximab vedotin is an antibody-drug conjugate (ADC) targeting CD30 that is in late-stage clinical trials for the treatment of relapsed and refractory Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL).

Data from a pivotal phase II trial of brentuximab vedotin in relapsed or refractory HL, which is fully enrolled, are expected in the second half of 2010. The trial is being conducted under a special protocol assessment with the U.S. Food and Drug Administration (FDA) and is designed to provide the basis for regulatory submissions in the United States and Europe in 2011.

Under the collaboration, Seattle Genetics will receive an upfront payment of $60 million and retains full commercialization rights for brentuximab vedotin in the United States and Canada. The Takeda Group will have exclusive rights to commercialize the product candidate in all countries other than the United States and Canada. Seattle Genetics is entitled to receive progress- and sales-dependent milestone payments in addition to tiered double-digit royalties based on net sales of brentuximab vedotin within the Takeda Group’s licensed territories. Milestone payments to Seattle Genetics could total more than $230 million. Seattle Genetics and the Takeda Group will jointly fund worldwide development costs on a 50:50 basis. Development funding by the Takeda Group over the first three years of the collaboration is expected to be at least $75 million. In Japan, the Takeda Group will be solely responsible for development costs.

“This collaboration aligns with our goal of rapidly bringing brentuximab vedotin to patients worldwide. Takeda is an ideal collaborator given its global presence, demonstrated commitment to oncology, and experience in the sales and marketing of first-in-class, targeted therapies for unmet medical needs,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer, Seattle Genetics. “Our retention of full commercial rights in the U.S. and Canada along with the financial terms from this agreement gives us a strong basis to begin building a commercial infrastructure for the planned launch of brentuximab vedotin. We expect to utilize this infrastructure in the future for other product candidates in our pipeline.”

“The addition of the late-stage product candidate brentuximab vedotin to our oncology development pipeline supports our mission to develop innovative new medicines where there is a high unmet need for patients,” said Deborah Dunsire, M.D., President and CEO, Millennium. “This collaboration closely aligns with our growth strategy, which includes both internal and external opportunities. We are very excited to bring forward a novel medicine which will help us increase our reach in oncology throughout Europe and the rest of the world.”

ADCs are monoclonal antibodies that carry potent, cell-killing drugs targeted precisely to tumor cells. Seattle Genetics has developed proprietary technology employing synthetic, highly potent drugs that can be attached to antibodies through stable linker systems. The linkers are designed to be stable in the bloodstream and release the drugs under specific conditions once inside targeted cells. This approach is intended to spare non-targeted cells and thus reduce many of the toxic side effects of traditional chemotherapy. Earlier this year, Millennium obtained an exclusive license to Seattle Genetics’ ADC technology for an antigen expressed on solid tumors, as well as options for two other licenses.

About Brentuximab Vedotin

Brentuximab vedotin is an ADC targeting CD30 utilizing Seattle Genetics’ proprietary technology. Brentuximab vedotin is currently being investigated in patients with relapsed or refractory HL or systemic ALCL. Brentuximab vedotin has received orphan drug designation from the FDA and the European Medicines Agency for both HL and ALCL and has received Fast Track designation by the FDA for HL. In two separate phase I clinical trials, brentuximab vedotin achieved objective responses in greater than 50 percent of patients treated at higher dose levels, including greater than 30 percent with complete remissions. Brentuximab vedotin was generally well tolerated. The majority of adverse events were Grade 1 and 2, with the most clinically important events being fatigue, fever, peripheral neuropathy, diarrhea, nausea and neutropenia.
