Inclusion Criteria:

Each patient must meet all of the following criteria to be enrolled in this study:

* Histologically and radiologically confirmed advanced metastatic CCRCC in patients who have had at least one prior systemic therapy, which can include axitinib for the dose escalation part. In the expansion and pilot phases, patients with prior axitinib are allowed, as long as the last dose of axitinib was longer than 6 months ago.
* Written and voluntary informed consent.
* At least one Response Evaluation Criteria In Solid Tumors (RECIST)-defined target lesion. \*Patient must have documented disease progression.
* Renal function (creatinine level within normal institutional limit, or creatinine clearance \>15 mL/min/1.73 m2 for patients with creatinine levels above institutional normal, calculated using the Cockcroft-Gault formula).
* Liver function (AST/ALT \<2.5 X institutional upper limit of normal OR \< 5 x institutional upper limit of normal in cases of liver metastases; Total bilirubin ≤ 1.5 times ULN.)
* Adequate hematological lab values including;

  * Absolute Neutrophil Count (ANC) ≥ 1.0 x 109/L
  * Platelets ≥ 100 x 109/L
  * Hemoglobin ≥ 7.0 g/dL
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 (fully active, able to carry on all pre-disease performance without restriction), 1 (restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, such as light housework or office work) or 2 (Ambulatory and capable of all self-care but unable to carry out any work activities; up and about more than 50% of waking hours).
* Age of at least 18 years.
* Life expectancy of 12 weeks and more.
* 2 weeks or more since end of previous systemic treatment (4 weeks or more for bevacizumab plus interferon-alfa). 3 days wash out for palliative radiation.
* Must have a safely accessible biopsy per treating physician and the provider performing that biopsy. Patient must agree to have this biopsy done as outlined in the calendar. If patient does not have safely accessible biopsy, the patient may still be enrolled per investigator discretion.

Exclusion Criteria:

Patients eligible for this study must not meet any of the following criteria:

* Patients with prior malignancies of the same or different tumor type in the last 5 years and patients with concurrent malignancies of the same or different tumor type UNLESS the natural history of the disease or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational drug.
* Symptomatic untreated metastases in the central nervous system.
* Subject that is pregnant or lactating.
* Pre-existing uncontrolled hypertension defined as \> 150/90 mm Hg with medication.
