Additional Relevant Details Cabozantinib reduced the risk of disease progression or death by 78% with a hazard ratio of 0.22 (96% CI 0.13 – 0.36; p<0.0001) at this planned interim analysis. The safety profile was consistent with that previously observed for cabozantinib.
“Considering the poor prognosis and lack of progress in the treatment of differentiated thyroid cancer following anti-VEGFR therapy, a significant improvement in progression-free survival is a long-awaited clinical advance,” said Marcia S. Brose, M.D., Ph.D., Full Professor of Otorhinolaryngology: Head and Neck Surgery and Director of the Center for Rare Cancers and Personalized Therapy at the Abramson Cancer Center of the University of Pennsylvania, and principal investigator of the trial. “These encouraging results from COSMIC-311 suggest cabozantinib has the potential to become an important new option for these patients. We look forward to sharing the detailed data from the trial at an upcoming medical meeting.”
