Seattle Genetics and Eos Biotechnology Collaborate To Develop Next Generation Antibody-Drug Conjugates For Cancer Therapy
June 5, 2001 at 12:00 AM EDT
Bothell, WA and South San Francisco, CA – June 5, 2001 – Seattle Genetics, Inc. (Nasdaq: SGEN) and Eos Biotechnology, Inc. announced today a collaboration to use Seattle Genetics’ toxic payload technology with Eos’ proprietary monoclonal antibodies directed against novel cancer targets derived from their analyses of the human genome. Seattle Genetics has fully synthetic, highly potent, novel drugs that can be used as payloads to dramatically increase the potency of monoclonal antibodies as therapeutic agents. Under the multi-year agreement, Seattle Genetics will provide broad access to their proprietary, novel classes of cell-killing drugs and their proprietary, specialized linkers, used to attach the drugs to antibodies. Eos will apply this technology towards developing therapeutic antibodies linked to these toxic payloads, to specifically target and kill tumor cells.
“The binding of an antibody to the surface of a cancer cell rarely induces cell death by itself,” stated Clay B. Siegall, Ph.D., President and Chief Scientific Officer at Seattle Genetics. “Enhancing the potency of antibodies through the linkage of drug payloads provides a means to selectively kill cancer cells while limiting damage to normal tissue.”
“Gaining access to Seattle Genetics’ technologies represents another important step for Eos in assembling and integrating the necessary tools to progress from new genome–derived targets directly to therapeutic candidates,” said David Martin, M.D., President and Chief Executive Officer of Eos. “Our goal is to quickly determine whether our antibodies interact with our novel targets in a therapeutically meaningful way. Since we choose our targets based on their specificity for the cancer cell, we believe that antibodies armed with potent payloads and directed to these targets could achieve that goal rapidly and frequently,” added Martin.
Under the terms of the agreement, Seattle Genetics will provide access both to its current technology of novel, fully synthetic payloads as well as any new technology developed during the course of the collaboration. Eos will pay an upfront technology access fee, milestone payments and royalties on net sales of any resulting products. Eos will be responsible for product development, manufacturing and marketing of any products generated through the collaboration.
“Seattle Genetics is committed to discovering and developing leading-edge antibody-drug conjugate technology for use with our internal programs as well as to partner with other companies,” stated H. Perry Fell, Ph.D., Chief Executive Officer of Seattle Genetics. “By working with Eos, we benefit by leveraging our internal work into a collaboration with a company committed to developing therapeutically useful products based on novel discoveries from analyzing the human genome. Eos benefits by gaining access to a sophisticated arsenal of next generation payloads to couple to their proprietary antibodies.”
About Seattle Genetics
Seattle Genetics discovers and develops monoclonal antibody, or mAb, -based therapeutics to treat cancer and related diseases. The Company utilizes its mAb-based technologies to increase the potency and efficacy of antibodies with specificity for cancer. Seattle Genetics has four mAb-based technologies: engineered mAbs, mAb-drug conjugates, single-chain immunotoxins and antibody-directed enzyme prodrug therapy. Using these technologies and its expertise in cancer, Seattle Genetics has built a diverse portfolio of drug candidates targeted to many types of human cancers, including two currently being tested in clinical trials.
