Titrating Cabozantinib in Metastatic Renal Cell Carcinoma Patients Using Goldilocks Principle: A Real-World Evidence Study

This study reinforces the existing data on effectiveness of cabozantinib as a later-line treatment for mRCC in real-world settings. We report 40 mg as the preferred landing zone. Furthermore we identify patients needing dose reductions due to toxicity as a subgroup carrying a significantly better prognosis. The results emphasize the importance of individual dosage for optimizing treatment outcomes and points out treatment-related toxicity as a surrogate marker for sufficient serum concentration of the active substance.
