Patients with advanced or metastatic renal cell carcinoma (RCC) derive a significant overall survival (OS) benefit from second-line treatment with the multi-tyrosine kinase inhibitor (TKI) cabozantinib relative to everolimus.
These findings come from the final analysis of the phase III METEOR trial in which 330 participants were randomly assigned to receive cabozantinib 60 mg/day and 328 allocated to the mammalian target of rapamycin inhibitor everolimus at a dose of 10 mg/day. All patients had received at least one previous vascular endothelial growth factor receptor TKI.
After a median follow-up of 18.7 and 18.8 months in the cabozantinib and everolimus arms, respectively, the corresponding median OS times were 21.4 and 16.5 months, a significant difference equating to a hazard ratio for death of 0.66.
Progression-free survival was also significantly improved in the cabozantinib arm, as was the objective response rate - findings that were consistent with the previously reported results for the first 375 randomly assigned patients, report Toni Choueiri (Dana-Farber Cancer Institute, Boston, Massachusetts, USA) and team.
They conclude in The Lancet Oncology: "Based on these results, cabozantinib should be considered as a new standard-of-care treatment option for previously treated patients with advanced renal cell carcinoma."
