Progression Free Survival (PFS)
PFS was defined as the time from first dose of study treatment (ie, start date) to the date of progression of disease (PD) by RECIST v 1.1 or death due to any cause, whichever occurred first. PFS data was censored on the date of the last adequate tumor assessment for participants without an event (PD or death), for participants who started new anti-cancer treatment prior to an event, or for participants with an event after two or more missing tumor assessments. PD as per RECIST v1.1 for target lesions was defined as 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed (over baseline if no decrease in the sum is observed during therapy), with a minimum absolute increase of 5 mm. For non-target lesions PD was defined as unequivocal progression of pre-existing lesions. Analysis was performed using Kaplan-Meier method.
Time frame: From start of study treatment until first documentation of PD or death due to any cause or censoring date (maximum of 24 months)
Population: Full Analysis Set included all participants who receive at least one dose of avelumab and axitinib. Participants were classified according to the study treatment received.

All nodes, both target and non-target, must decrease to normal (short axis \<10 mm). No new lesions. PR was defined as \>=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Analysis was performed using Kaplan-Meier method.
Time frame: From date of start of treatment until date of first documentation of objective tumor response (maximum up to 56 months)
