Everolimus/Sorafenib or Sunitinib in Patients With Metastatic Renal Cell Carcinoma (RCC)

INCLUSION CRITERIA

1. Histologically- or cytologically-confirmed renal cell carcinoma, which is unresectable or metastatic and of any of the following histologies: clear cell, papillary, chromophobic, oncocytic, unclassified, or mixed. A component of clear cell histology must be present. Tumors with pure collecting duct histology are not eligible.
2. Cytoreductive nephrectomy is allowed but not required
3. Evidence of RECIST-defined measurable disease (lesions that can be accurately measured in at least one dimension with the longest diameter ≥ 20mm using conventional techniques or ≥ 10 mm with spiral CT scan)

4. Male or female at least 18 years old

   1. Female patients must be either surgically sterile or postmenopausal, or if of childbearing potential must have a negative pregnancy test (serum or urine) prior to enrollment and agree to use effective barrier contraception during the period of therapy, and for 3 months after the end of treatment/end of participation in the study. Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are therefore not considered effective for this study.
   2. Male patients must be surgically sterile or must agree to use effective contraception during the period of therapy, and for 3 months after the end of treatment/end of participation in the study.
   3. The definition of effective contraception will be based on the judgment of the investigator.
5. ECOG performance status 0-1

6. Adequate bone marrow function:

   1. ANC ≥ 1500/uL
   2. platelet count ≥ 100,000/uL
   3. hemoglobin ≥ 9.0 g/dL

7. Adequate hepatic function:

   1. Total bilirubin ≤ 1.5 X ULN
   2. AST (SGOT) ≤ 2.5 X ULN
   3. ALT (SGPT) ≤ 2.5 X ULN

8. Adequate renal function as determined by either:

   1. Calculated or measured creatinine clearance ≥ 40 mL/min (for calculated creatinine clearance, Cockroft-Gault equation will be used)

      Modified Cockcroft-Gault formula:

      ((140 - age (yrs)) x (actual weight(kg))) / (72 x serum creatinine(mg/dl))

      * Multiply by another factor of 0.85 if female

   2. Serum creatinine ≤ 1.5 X ULN
9. Able to swallow oral medications
10. Total fasting serum cholesterol ≤ 300 mg/dL
11. Resolution of any pre-existing toxicity from prior therapy to NCI CTCAE V3.0 ≤ grade 1 (with the exception of hypertension, hypothyroidism)
12. Signed and dated informed consent document
13. Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.
14. More than 28 days since any prior therapy, including investigational agents and surgical procedures.

EXCLUSION CRITERIA

1. Collecting duct renal cell carcinoma is excluded. Transitional cell carcinoma of the renal pelvis is excluded.
2. Prior systemic regimens for renal cell carcinoma (neoadjuvant therapy is acceptable as long as it did not include sunitinib, sorafenib, everolimus, or temsirolimus). A prior therapy which was started and stopped after no more than four weeks of therapy will not constitute a prior systemic regimen.
3. Prior surgery, radiation therapy, or systemic therapy for renal cell carcinoma within 4 weeks of starting study treatment.
4. History of or known brain metastasis, spinal cord compression, or carcinomatous meningitis, or new evidence of brain or leptomeningeal disease on screening CT or MRI scan (evaluation for CNS disease is required to be performed for eligibility).
5. Any of the following within 6 months prior to study drug administration: myocardial infarction, unstable or severe angina, coronary or peripheral artery bypass graft, NYHA functional Class II, III, IV congestive heart failure, cerebrovascular accident or transient ischemic attack, or pulmonary embolism.
6. Ejection fraction lower than institutional lower limit of normal by echocardiogram or MUGA.
7. Hypertension that is unable to be controlled with medications to a blood pressure of ≤ 150/90.
8. Hypothyroidism that is unable to be controlled with medications such that FT4 is outside of normal limits.
9. QTc prolongation (QTc interval ≥ 480 msecs) or any other clinically significant ECG abnormalities.
10. Known human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS)-related illness (because of the immunosuppressive effects of therapy). Testing for HIV in the absence of a history or symptoms is not required.
11. Hepatitis B or C (because of the risk of reactivation). The following serologies are acceptable for enrollment: HBsAg-/anti-HBc-/anti-HBs-; HBsAg-/anti-HBc+/anti-HBs+; HBsAg-/anti-HBc-/anti-HBs+. The following serologies are not acceptable for enrollment: HBsAg+/anti-HBc+(IgM+/-)/anti-HBs-. If the following serologies are obtained, additional testing will be required to ascertain the patient's hepatitis B status: HBsAg-/anti-HBc+/anti-HBs-.
12. "Currently active" second malignancy other than non-melanoma skin cancers. Patients are not considered to have a "currently active" malignancy if they have completed therapy and are considered to have a less than 30% risk of relapse.
13. Current treatment on another clinical trial.
14. Pregnant or breastfeeding.
15. Chronic treatment with systemic steroids or other immunosuppressive agent.
16. On oral vitamin K antagonist medication (except low dose warfarin) (other anticoagulants are allowed).
17. History of malabsorption syndrome, disease significantly affecting gastrointestinal function or major resection of stomach or small bowel that could interfere with absorption, distribution, metabolism, or excretion of study drugs.
18. Any serious and/or unstable pre-existing medical, psychiatric, or other condition (including lab abnormalities) that could interfere with subject safety or obtaining informed consent. Examples of such include uncontrolled diabetes as defined by fasting serum glucose >1.5 x ULN (Note: optimal glycemic control should be achieved before starting trial therapy), nonhealing wound, severe infection, severe malnutrition, ventricular arrhythmias, active ischemic heart disease, chronic liver or renal disease, or active upper GI tract ulceration.
19. Patients should not receive immunization with attenuated live vaccines within one week of study entry or during study period. Close contact with those who have received attenuated live vaccines should be avoided during treatment with everolimus. Examples of live vaccines include intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella and TY21a typhoid vaccines.
