Median duration of response (DOR) was 10.2 versus 5.7 months in spartalizumab versus chemotherapy arms, respectively. Median overall survival (OS) was 25.2 and 15.5 months in spartalizumab and chemotherapy arms, respectively. Tumor RNA sequencing showed a correlation between response to spartalizumab and IFN-γ, LAG-3, and TIM-3 gene expression.
