Brief Summary:
This is a phase II trial that follows the completion of the phase I UCSF trial of everolimus and sorafenib for Renal Cell Carcinoma (RCC). This trial will be for patients who have not had treatment for RCC before. This trial will have 2/3 patients getting everolimus/sorafenib treatment and 1/3 getting sunitinib, an FDA approved RCC drug. All three drugs are approved for advanced RCC when used individually, the combination of everolimus and sorafenib for RCC is not approved by the FDA.

Condition or disease Intervention/treatment Phase
Locally Metastatic Malignant Neoplasm Drug: Everolimus and sorafenib Drug: Sunitinib monotherapy Phase 2

Detailed Description:
In the phase I study of the combination of everolimus and sorafenib, clinical benefit was observed in patients with no prior systemic therapy. There was no evidence of pharmacokinetic interaction and acceptable toxicity at a dosage of sorafenib of 400 mg twice daily (BID) and everolimus 5 mg daily. Based on these data and the need for more effective front-line therapy for renal cell carcinoma, the plan is to investigate this regimen in patients who have not undergone prior therapy. A sunitinib arm is being included as a concurrent reference to help provide a guideline of an activity level and toxicity that would be meaningful to move forward to a phase III study. Therefore, this study is designed as a non-comparative investigation and patients will be randomized in a 2:1 ratio to everolimus/sorafenib or to sunitinib, respectively.

Primary Purpose: Treatment
Official Title: A Randomized Non-Comparative Multicenter Phase II Study of Everolimus/Sorafenib or Sunitinib in Patients With Metastatic Renal Cell Carcinoma (RCC)
Study Start Date : July 2012
Estimated Primary Completion Date : December 2015
Estimated Study Completion Date : April 2016

Arm Intervention/treatment
Experimental: Everolimus/Sorafenib
Patients will be stratified by current smoking status (smoker: yes or no0, for each smoking stratum patients will be randomized in a 2:1 ratio
Drug: Everolimus and sorafenib
  • Starting doses: everolimus 5 mg daily and sorafenib 400 mg BID - taken fasting, no food 1 hour before or 2 hours after dosing
  • Everolimus and sorafenib are dosed continuously

(Note: everolimus and sorafenib are typically dosed in 28 day cycles, and sunitinib is typically dosed in 42 day cycles; for the purposes of this protocol to keep timing consistent, a cycle will be defined as 42 days of therapy)

Active Comparator: Sunitinib
  • Sunitinib is the concurrent control group
  • Patients will be stratified by current smoking status (smoker: yes or no), for each smoking stratum patients will be randomized in a 2:1 ratio
Drug: Sunitinib monotherapy

Starting dose: sunitinib 50 mg daily 4 weeks on, 2 weeks off - taken fasting, no food 1 hour before or 2 hours after dosing

(Note: sunitinib is typically dosed in 42 day cycles described above: 28 days treatment, 14 days off. For the purposes of this protocol, to keep timing consistent, a cycle will be defined as 42 days of therapy)

Primary Outcome Measures :
  1. Objective response [ Time Frame: 12-18 weeks ]

    Computerized Tomography Scans (CT) done at Screening and every 2 cycles

    • For Partial Response (PR) or Complete Response (CR), changes in tumor measurements must be confirmed by repeat studies no less than 4 weeks after the criteria for response are first met (RECIST 1.1 criteria)
    • For Stable Disease (SD), follow-up measurements must have met the SD criteria at least once after study entry at a minimum of 12 weeks after study entry

Secondary Outcome Measures :
  1. Safety: combination of everolimus and sorafenib [ Time Frame: 12-18 weeks ]
    Safety/Adverse Event (AE) assessments done on Day 1, 21, 42 during Cycle 1 & Day 28 of all subsuquent cycles; assessments include Eastern Oncology Group Conference (ECOG) Performance scale, physical/history, hematology & chemistry labs; other safety data (e.g. Electrocardiogram [ECG], Multigated Acquisition Scan [MUGA], etc.) will be considered as appropriate

  2. Progression-free Survival (PFS) [ Time Frame: 12-18 weeks ]
    - PFS will be measured (using RECIST 1.1 criteria) from the start of protocol therapy until the date of the first occurrence of recurrent or progressive disease or death

  3. Time-to-Progression (TTP) [ Time Frame: 12-18 weeks ]
    - TTP will be measured from the start of protocol therapy until first date that recurrent or progressive disease is documented

  4. Clinical Benefit rate [ Time Frame: 12-18 weeks ]
    Clinical benefit (defined as objective response+stable disease) will be summarized for each treatment arm by the proportion of patients achieving this outcome with 95% confidence intervals

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  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)

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.
