Kaplan Meier curve estimating PFS for 55 patients from the next line of systemic therapy for kidney cancer after discontinuation of IO-VEGF. Median PFS was 12 months (95% CI, 8.2–24.5) and 12-month PFS probability was 49.6% (95% CI, 33.2–64.0). Median follow up time for progression-free survivors was 8.5 months (range: 0, 30).
