Women must not be breastfeeding
Men who are sexually active with women of childbearing potential must use any contraceptive method with a failure rate of less than 1% per year
Contraception should be continued using two highly effective methods for a period of 90 days
Serum creatinine =< 1.5 x upper limit of normal (ULN) OR creatinine clearance (CrCl) >= 40 mL/min (measured or calculated using the Cockcroft-Gault formula) using actual weight (ideal or adjusted weights are unacceptable)

Exclusion Criteria:

Patients with known symptomatic brain metastases requiring systemic corticosteroids; patients with previously diagnosed brain metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to the start of study medication, have discontinued corticosteroid treatment for these metastases for at least 4 weeks and are neurologically stable; mild neurological deficit is allowed, if it does not interfere with the ability to judge the safety on the trial
Prior treatment with an mTOR inhibitor (including, but not limited to, everolimus, temsirolimus, sirolimus, and ridaforolimus)
Prior treatment with axitinib
History of or active autoimmune disorders (including but not limited to: Crohn's disease, rheumatoid arthritis, scleroderma, systemic lupus erythematosus, Grave's disease) and other conditions that compromise or impair the immune system
Active bacterial, fungal or viral infection including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) -related illness
Any condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days prior to the first dose of study drug; inhaled steroids and adrenal replacement steroid doses > 10 mg daily prednisone equivalent are permitted in the absence of active autoimmune disease
Uncontrolled adrenal insufficiency
Any known active chronic liver disease

Known medical condition (e.g., a condition associated with diarrhea or acute diverticulitis) that, in the investigator's opinion, would increase the risk associated with study participation or study drug administration or interfere with the interpretation of safety results
Prior treatment with an anti-CD137, or OX40 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways except anti-PD1, anti-PDL1/2 antibodies or ipilimumab
Major surgery less than 6 weeks prior to the first dose of study drug; minor surgery less than 4 weeks prior to the first dose of study drug

Presence of toxicities attributed to prior therapy other than alopecia that have not resolved to grade 1 (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] version 4) or baseline before administration of study drug
History of grade 3 or higher immune-mediated adverse event (including AST/ALT elevations that where considered drug related and cytokine release syndrome) that was considered related to prior immune-modulatory therapy (e.g., checkpoint inhibitors, costimulatory agents etc.) or any grade immune-related adverse events (AEs) that required immune suppressive therapy
