Seattle Genetics Adds Patent to 2025
Seattle Genetics, the developer of antibody treatments for cancer, said today it has received a new patent which will extend its proprietary rights to its lead drug for Hodgkin’s disease until at least 2025. The U.S. patent covers technology for a linker that selectively unloads a potent toxin called auristatin on the target cell of interest. This is the technology Seattle Genetics uses in its lead “empowered antibody” program called brentuximab vedotin (SGN-35), and which several of its partners use under licenses. Seattle Genetics expects to seek FDA approval of brentuximab vedotin to treat Hodgkin’s disease in the first half of 2011.
