Abbreviations: CR, complete response; NE, not estimable; OS, overall survival; PFS, progression-free survival; PR, partial response; RCC, renal cell carcinoma.
Objective response rates were calculated based on confirmed responses: ([CR + PR]/ No.) × 100. CIs were calculated using Clopper-Pearson method. Individual patient responses were adjudicated per RECIST (version 1.0) with modification. One CR was noted (in 10-mg/kg cohort).
Kaplan-Meier estimate; time from first response to time of documented progression, death, or (for censored data denoted by +) time to last tumor assessment.
