In our sight, Exelixis enters into 2024 at a variation aspect, through which the growth of its crown jewel Cabometyx franchise is actually maintaining while pipe plans, especially zanzalintinib, are actually keeping raising task to make up for Cabometyx's market singularity expiry in 2031," William Blair professionals stated in an Aug. 7 details." In the midterm, NETs and also [metastatic castration-resistant prostate cancer cells] can become material growth opportunities for the franchise business," the analysts added.It's been actually a year of adjustment at Exelixis, which laid off 175 employees-- comparable to around 13% of its own staff-- in January as component of a wider restructuring targeted at "concentrate [ing] R&D resources to accelerate our surfacing pipe."
