Exelixis Announces Results from Subgroup Analysis of Phase 3 CABINET Pivotal Trial Evaluating CABOMETYX® (cabozantinib) in Non-Functional and Functional Neuroendocrine Tumors at ASCO 2026
– CABOMETYX significantly reduced the risk of disease progression or death by 74% and 60% in patients with non-functional and functional advanced NET, respectively, versus placebo –
Exelixis, Inc. (Nasdaq: EXEL) today announced results from a subgroup analysis of the phase 3 CABINET pivotal trial, which showed that CABOMETYX® (cabozantinib) provided significant improvements in progression-free survival (PFS) versus placebo in patients with previously treated advanced neuroendocrine tumors (NET) regardless of functional status. These data will be presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting to be held from May 29 – June 2 in Chicago.
“Understanding the effects of oral pathway inhibitors in patients with both functional and non-functional NET is critical in informing appropriate treatment-sequencing decisions,” said Nikolaos A. Trikalinos, M.D., Associate Professor of Medicine, Washington University School of Medicine and Siteman Cancer Center. “Patients with hormone-producing tumors may require approaches that not only control tumor growth but also help mitigate challenging hormone-related symptoms. It is encouraging that our results reinforce cabozantinib as a meaningful treatment option for patients with advanced NET regardless of functional status. In both non-functional and functional NET, cabozantinib delivered substantial improvements in disease control compared to placebo, with median progression-free survival increasing threefold in non-functional NET and more than doubling in functional NET compared to placebo.”
