In our view, Exelixis enters into 2024 at a variation aspect, in which the development of its own flagship Cabometyx franchise is actually supporting while pipeline programs, particularly zanzalintinib, are keeping improving task to counter Cabometyx's market singularity expiration in 2031," William Blair professionals pointed out in an Aug. 7 keep in mind." In the midterm, NETs and [metastatic castration-resistant prostate cancer cells] could emerge as worldly development opportunities for the franchise," the professionals added.It's been actually a year of improvement at Exelixis, which laid off 175 staff members-- equivalent to all around 13% of its own workforce-- in January as aspect of a more comprehensive restructuring intended for "concentrate [ing] R&D resources to progress our surfacing pipeline."
