Title A Randomized Phase II Study of Everolimus (Afinitor) vs. Sunitinib (Sutent) in Patients with Metastatic Non-Clear Cell Renal Cell Carcinoma (ASPEN)


CC CC00006

Hospital Main Campus

Stage N/A

Phase Phase 2

Disease Renal

Drug Everolimus, Sunitinib



  1. The primary objective will be to compare the anti-tumor activity of everolimus and sunitinib in subjects with mRCC with non-clear cell pathology, as measured by progression-free survival (PFS) following treatment initiation according to RECIST criteria. In addition, the rates of PFS will be compared at 6, 12 and 24 months.
  1. A secondary objective will be to compare the antitumor activity of these agents against historic interferon-treated controls from the phase III sunitinib trial of untreated patients with RCC using the log-rank test. Other secondary objectives will be to compare the safety, tolerability, and quality-of-life associated with everolimus or sunitinib administration in this population, to compare the overall response rates and degree of tumor shrinkage in each arm, overall survival in each arm, and to compare the time to new metastases in each arm. Finally, tumor, plasma and urine biomarkers will be correlated with response and PFS in patients with advanced non clear cell RCC treated with everolimus or sunitinib, with an emphasis on mTOR pathway and VEGF pathway activation, DNA polymorphisms and mutational analysis, and longitudinal plasma/urine angiokine levels.

Exclusion Criteria

Exclusion Criteria

  1. Subjects with active central nervous system (CNS) metastases. CNS metastases are allowed provided they have been treated and have been stable without new or growing lesions for 6 weeks.
  2. Prior systemic therapy for RCC, including mTOR and anti-angiogenic therapy, chemotherapy, biologic or experimental therapy.
  3. Collecting duct, medullary, small cell, oncocytoma, or lymphoma-type pathology is not allowed. Sarcomatoid variants of papillary or chromophobe carcinoma is permitted but not if clear cell features are predominant (> 50% involvement).
  4. Subjects receiving known strong CYP3A4 isoenzyme inhibitors and/or inducers (Attachment 3). Subjects on acceptable CYP3A4 isoenzyme inhibitors and/or inducers are eligible, provided they have been taking a stable regimen for at least 4 weeks prior to screening. Agents not appearing in Attachment 3 are permitted.
  5. Major surgery, open biopsy, traumatic injury, or radiotherapy within 4 weeks of the screening visit.
  6. Subjects who have not recovered from prior biopsy, surgery, traumatic injury, and/or radiation therapy.
  7. Presence of a non-healing wound or ulcer.
  8. Grade ≥ 3 hemorrhage within the past month.
  9. Hypertension with systolic blood pressure of ≥ 180 mm Hg and/or diastolic pressure ≥ 100 mm Hg. Anti-hypertensive medications are permitted.
  10. Subjects with American Heart Association (AHA) Class 2-4 heart disease (Attachment 4) or any history of congestive heart failure with an ejection fraction < 50%, or history of unstable angina, myocardial infarction, coronary artery bypass graft, cerebrovascular accident, transient ischemic attack, or pulmonary embolism within 6 months of entry.
  11. Diabetes mellitus with glycosylated hemoglobin A1c (HbgA1c) > 10% despite therapy. Note: Optimal glycemic control should be achieved before starting trial therapy.
  12. A history of interstitial pneumonitis.
  13. Subjects with active autoimmune disorder(s) being treated with immunosuppressive agents within 4 weeks prior to the screening visit.
  14. Subjects receiving immunosuppressive agents and those with chronic viral/bacterial/fungal illnesses such as human immunodeficiency virus (HIV). Replacement doses of corticosteroids are permitted. See below for eligibility of HBV/HCV-infected individuals.
  15. 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.
