Clinical Data At the time of the analysis, the median duration of treatment in the trial was 8.3 months with CABOMETYX versus 4.4 months with everolimus. Dose reductions occurred for 62 percent and 25 percent of patients, respectively. Discontinuation rate due to an adverse event not related to disease progression was 12 percent with CABOMETYX and 11 percent with everolimus.
The most common grade 3 or 4 adverse events were hypertension (15 percent), diarrhea (13 percent) and fatigue (11 percent) in the CABOMETYX arm and anemia (17 percent), fatigue (7 percent) and hyperglycemia (5 percent) in the everolimus arm. Serious adverse events ≥ grade 3 occurred in 130 (39 percent) of cabozantinib-treated patients and in 129 (40 percent) of everolimus-treated patients.
