In our view, Exelixis enters 2024 at an inflection factor, through which the development of its main Cabometyx franchise business is actually supporting while pipe plans, particularly zanzalintinib, are carrying enhancing responsibility to offset Cabometyx's market singularity expiration in 2031," William Blair professionals pointed out in an Aug. 7 details." In the midterm, Webs and [metastatic castration-resistant prostate cancer] could become material growth possibilities for the franchise," the professionals added.It's been a year of modification at Exelixis, which laid off 175 staff members-- equivalent to around thirteen% of its own labor force-- in January as component of a wider rebuilding intended for "concentrate [ing] R&D information to evolve our arising pipeline."
