In our viewpoint, Exelixis enters into 2024 at an inflection aspect, through which the development of its front runner Cabometyx franchise business is stabilizing while pipeline programs, particularly zanzalintinib, are actually carrying increasing task to balance out Cabometyx's market singularity expiration in 2031," William Blair professionals stated in an Aug. 7 note." In the midterm, Internet and [metastatic castration-resistant prostate cancer] could emerge as material development opportunities for the franchise," the analysts added.It's been actually a year of modification at Exelixis, which gave up 175 workers-- equal to about thirteen% of its labor force-- in January as component of a broader rebuilding focused on "concentrate [ing] R&ampD resources to evolve our arising pipe."
