Overall survival was defined as the time (in months) from the date of randomization to the date of death due to any cause. Participants last known to be alive were censored at date of last contact. Analysis was performed using Kaplan-Meier method.

PFS: time from the date of randomization to the date of the first documentation of progressive disease (PD) according to Response Evaluation Criteria in Solid Tumours (RECIST version \[v\] 1.1) or death due to any cause, whichever occurred first as assessed by BICR. PFS data was censored on date of last adequate tumor assessment for participants who did not have an event (PD or death), who started new anti-cancer therapy prior to an event or for participants with an event after 2 or more missing tumor assessments. PD was defined as at least a 20 percent (%), increase in the sum of all the longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to relative increase of 20 %, sum must have also demonstrated an absolute more than (\>) of at least 5 millimeter (mm). The appearance of one or more new lesions was also considered progression.

OS was defined as the time from the date of randomization to the date of death due to any cause. Participants last known to be alive were censored at date of last contact. Analysis was performed using Kaplan-Meier method.

PFS is defined as the time from date of randomization to the date of the first documentation of progression of disease (PD) or death due to any cause, whichever occurs first. PFS time was summarized by treatment arm using the Kaplan-Meier method. PFS based on BICR assessment was evaluated for this endpoint.

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs were graded by investigator according to NCI CTCAE v.4.03 as follows: Grade 1: mild AE, Grade 2: moderate AE, Grade 3: severe AE, Grade 4: life-threatening consequences and urgent intervention indicated, Grade 5: death related to AE.

As per NCI-CTCAE v 4.03, anemia Grade 1= Less than (\<) lower limit of normal (LLN) to 100 gram per liter (g/L),Grade 2= \<100 to 80 g/L; hemoglobin increased: Grade 1= increase of greater than (\>) 0 to 2 gram per deciliter(g/dL) above upper limit of normal \[ULN\]; lymphocyte count decreased: Grade 1= \<LLN to 0.8\*10\^9/L, Grade 2= \<0.8\*10\^9/L to 0.5\*10\^9/L, Grade 3= \<0.5\*10\^9/L to 0.2\*10\^9/L ; lymphocyte count increased: Grade 2= \>4\*10\^9/L to 20\*10\^9/L; neutrophil count decreased: Grade 1= \<LLN to 1.5\*10\^9/L ,Grade 2= \<1.5\*10\^9/L to 1.0\*10\^9/L; platelet count decreased: Grade 1= \<LLN to 75.0\*10\^9/L, Grade 2= \<75.0\*10\^9/L to 50.0\*10\^9/L; white blood cell decreased: Grade 1= \<LLN to 3\*10\^9/L, Grade 2= \<3\*10\^9/L to 2\*10\^9/L.

DLT: greater than or equal to (\>=) Grade 3 hematologic/non-hematologic toxicity, Grade 3-4 liver-related laboratory test elevation (alanine aminotransferase, aspartate aminotransferase) with Grade 2 elevation of total bilirubin, non-hematologic Grade 3 laboratory abnormality (required medical intervention to treat participant/led to hospitalization), inability to complete \>=75% of first 2 cycles doses of axitinib (from Cycle 1 Day 1 after completion of lead-in period) or 2 infusions of avelumab within DLT observation period due to investigational product related toxicity.
