Supported by revenues from their marketed products and collaborations, they are committed to prudently reinvesting in their business to maximize the potential of their pipeline. /They are supplementing their existing therapeutic assets with targeted business development activities and internal drug discovery — all to deliver the next generation of Exelixis medicines and help patients recover stronger and live longer.
