About the Seattle Genetics / Agensys CollaborationSeattle Genetics and Agensys entered into the ADC collaboration in January 2007, and expanded it in November 2009. Under the collaboration, Agensys has the right to obtain exclusive ADC licenses for multiple cancer targets. The companies are co-developing and will globally co-commercialize and share profits on a 50:50 basis for ASG-5ME, ASG-22ME and ASG-15ME. Any ADC programs to which Seattle Genetics does not opt-in will be developed and commercialized exclusively by Agensys, and Seattle Genetics is entitled to progress-dependent fees, milestone payments and mid-single-digit royalties on worldwide net sales of such products. ADCs are monoclonal antibodies that are designed to selectively deliver cytotoxic agents to tumor cells. With over a decade of experience and knowledge in ADC innovation, Seattle Genetics has developed proprietary technology employing synthetic cytotoxic agents and stable linker systems that attach these cytotoxic agents to the antibody. Seattle Genetics’ linker systems are designed to be stable in the bloodstream and release the potent cell-killing agent once inside targeted cancer cells. This approach is intended to spare non-targeted cells and thus reduce many of the toxic effects of traditional chemotherapy while enhancing antitumor activity. Agensys utilizes its portfolio of novel cancer targets to generate high-affinity fully human, proprietary antibodies, and combines selected antibodies with Seattle Genetics’ ADC technology to produce new cancer therapies. About Seattle Genetics Seattle Genetics is a biotechnology company focused on the development and commercialization of monoclonal antibody-based therapies for the treatment of cancer. The company’s lead program, ADCETRIS ® (brentuximab vedotin), received accelerated approval from the U.S. Food and Drug Administration in August 2011 and approval with conditions from Health Canada in February 2013 for two indications.
