I. To determine whether a statistically significant improvement in progression free survival exists for patients receiving the combination.
I. To determine whether the combination is safe and whether objective response rate (ORR), duration of response (DOR) and overall survival (OS) improve as a result of treatment with combination of axitinib + anti-OX40 antibody PF-04518600 (PF‐04518600 [OX40 Ab]) compared to axitinib + placebo.
I. To determine whether pre and post treatment specimens collected during the trial demonstrate significant changes in tumor microenvironment and enhanced immune response to tumor cells.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive axitinib orally (PO) twice daily (BID) on days 1-14 and anti-OX40 antibody PF-04518600 intravenously (IV) over 60 minutes on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive axitinib as in Arm I and placebo IV on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30, 90, and 180 days.

Experimental: Arm I (axitinib, anti-OX40 antibody PF-04518600)
Patients receive axitinib PO BID on days 1-14 and anti-OX40 antibody PF-04518600 IV over 60 minutes on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
Biological: Anti-OX40 Antibody PF-04518600
Other Name: PF-04518600
Other: Laboratory Biomarker Analysis
Active Comparator: Arm II (axitinib, placebo)
Patients receive axitinib as in Arm I and placebo IV on day 1 beginning with course 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
Other: Laboratory Biomarker Analysis
- Progression‐free survival (PFS) [ Time Frame: Time from randomization until the earliest of documented disease progression (confirmed progression of disease) or death, assessed for up to 180 days ]The statistical comparison of PFS in the two treatment arms will be based on the stratified logrank test.
- Incidence of unacceptable toxicity [ Time Frame: Up to the beginning of the third course (29 days) ]Defined as any toxicity or toxicities that necessitate the patient being removed from protocol therapy within the first 2 courses of therapy, or which cause a more than 6‐week interruption of therapy or delay in starting a next course, up to the beginning of the 3rd therapy course.
- ORR defined as either complete response or partial response occurring any time during treatment and assessed by RECIST 1.1 and immune-related RECIST (irRECIST) criteria [ Time Frame: Up to 180 days ]The two arms will also be compared using a one‐sided 0.05‐level Pearson chi‐square test.
