In our sight, Exelixis enters 2024 at a variation point, in which the development of its own flagship Cabometyx franchise is actually stabilizing while pipe systems, particularly zanzalintinib, are supporting improving responsibility to make up for Cabometyx's market exclusivity expiration in 2031," William Blair professionals claimed in an Aug. 7 note." In the midterm, NETs as well as [metastatic castration-resistant prostate cancer] could possibly emerge as worldly growth options for the franchise business," the experts added.It's been a year of improvement at Exelixis, which gave up 175 workers-- comparable to about thirteen% of its labor force-- in January as aspect of a broader rebuilding intended for "concentrate [ing] R&D sources to progress our arising pipeline."
