In our perspective, Exelixis enters into 2024 at a variation point, in which the growth of its main Cabometyx franchise business is maintaining while pipe systems, particularly zanzalintinib, are keeping raising duty to make up for Cabometyx's market exclusivity expiry in 2031," William Blair professionals said in an Aug. 7 keep in mind." In the midterm, Webs and also [metastatic castration-resistant prostate cancer] could become material growth opportunities for the franchise business," the professionals added.It's been actually a year of improvement at Exelixis, which laid off 175 workers-- equivalent to about 13% of its own staff-- in January as component of a more comprehensive rebuilding focused on "concentrate [ing] R&ampD resources to accelerate our surfacing pipeline." At the time, that tactic featured advancing XB002 with a phase 1 hardship.
