FDA accepted the supplemental new drug application for Cabometyx (cabozantinib) for patients with advanced neuroendocrine tumors
Exelixis, Inc. announced that its supplemental New Drug Application (sNDA) for cabozantinib (Cabometyx) has been accepted in the U.S.
for: 1) the treatment of adults with previously treated, locally advanced/unresectable or metastatic, well- or moderately differentiated pancreatic neuroendocrine tumors (pNET), and 2) the treatment of adults with previously treated, locally advanced/unresectable or metastatic, well- or moderately differentiated extra-pancreatic NET (epNET).
The FDA also granted orphan drug designation to cabozantinib for the treatment of pNET. The FDA assigned a standard review with a Prescription Drug User Fee Act target action date of April 3, 2025.
The sNDA is based on the final results of the phase III CABINET pivotal trial evaluating cabozantinib compared with placebo in two cohorts of patients with previously treated NET: advanced pNET and advanced epNET. As previously announced, CABINET was stopped early for compelling activity; all patients were unblinded and those on placebo were given the option to cross over to active treatment with cabozantinib. This early stopping was due to a dramatic improvement in progression-free survival (PFS) observed at an interim analysis in both cohorts.
