• Severe active infection requiring systemic treatment within 28 days before the first dose of study treatment
• Serious non-healing wound/ulcer/bone fracture within 28 days before the first dose of study treatment
• Major surgery (e.g., GI surgery, removal or biopsy of brain metastasis) within 8 weeks before first dose of study treatment. Complete wound healing from major surgery must have occurred 1 month before first dose and from minor surgery (e.g., simple excision, tooth extraction) at least 10 days before first dose. Subjects with clinically relevant ongoing complications from prior surgery are not eligible.
• Concurrent uncompensated hypothyroidism
• Treatment with any investigational drug within 28 days prior to registration.

Other illness

• Uncontrolled bleeding, hypertension, or cardiovascular disease.
• The subject has active brain metastases or epidural disease
• Cavitating pulmonary lesion(s) or known endotracheal or endobronchial disease manifestation.
• Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment
• History of organ transplant
• Active infection requiring systemic therapy
• Known additional malignancy that is active and/or progressive requiring treatment; exceptions include basal cell or squamous cell skin cancer, in situ cervical or bladder cancer, or other cancer for which the subject has been disease-free for at least 2 years.

Lab values

• The subject has prothrombin time (PT)/ International Normalized Ratio (INR) or partial thromboplastin time (PTT) test ≥1.3 x the laboratory upper limit of normal (ULN)
• Cardiovascular disorders including:
  • Congestive heart failure (CHF): New York Heart Association (NYHA) Class III (moderate) or Class IV (severe) at the time of screening
  • Concurrent uncontrolled hypertension defined as sustained BP \> 150 mm Hg systolic, or \> 100 mm Hg diastolic despite optimal antihypertensive treatment within 14 days of the first dose of study treatment.
  • The subject has a corrected QT interval calculated by the Fridericia formula (QTcF) \>500 ms within 28 days before registration.

Other

• Unable to swallow tablets
• Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
• Active central nervous system (CNS) metastases

• Written informed consent and HIPAA authorization for release of personal health information.
• Age ≥ 18years at the time of consent.
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-1 within 28 days prior to registration.
• Radiographically consistent with metastatic renal cell carcinoma (with subsequent pathologic confirmation of renal cell carcinoma with a clear cell component) OR histological/ cytological evidence of metastatic renal cell carcinoma with a clear cell component
• Measurable tumor in the kidney according to RECIST 1.1
• No prior therapy for metastatic renal cell carcinoma
• Demonstrate adequate organ function as defined in the protocol; all screening labs to be obtained within 14 days prior to registration.
• Females of childbearing potential must have a negative serum pregnancy test during screening, within 14 days of Cycle 1 Day 1. NOTE: Females are considered of child bearing potential unless they are surgically sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months
• Females of childbearing potential and males must be willing to abstain from heterosexual activity or to use 2 forms of effective methods of contraception from the time of informed consent until 6 months after treatment discontinuation. The two contraception methods can be comprised of two barrier methods, or a barrier method plus a hormonal method.
• As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study
