BOTHELL, Wash.–(BUSINESS WIRE)–Seattle Genetics, Inc. (Nasdaq:SGEN) today released the following statement in response to Daiichi Sankyo’s filing of a Declaratory Judgment action alleging Seattle Genetics is not entitled to intellectual property rights under a collaboration between the two companies for the development of antibody-drug conjugates (ADCs):
ADC technology used in Daiichi Sankyo’s metastatic breast cancer drug candidate (DS-8201, [Fam-] trastuzumab deruxtecan) among other product candidates, rightfully belongs to Seattle Genetics under the agreement entered into between the two parties in 2008. The linker and other ADC technology used in these drug candidates are improvements to Seattle Genetics’ pioneering ADC technology, the ownership of which are automatically assigned to Seattle Genetics under the terms of the agreement. Seattle Genetics has been abiding by the dispute resolution provisions under the agreement to pursue its legal rights. By filing this lawsuit, Daiichi Sankyo has circumvented the process underway between the parties pursuant to these provisions. Seattle Genetics is committed to protecting the company’s intellectual property rights as it continues to find revolutionary new treatments for cancer patients.
