Detailed Description

This will be an international (USA, Canada, and UK) open-label, outpatient, multicenter, randomized study of treatment with RAD001 (everolimus (Afinitor®) or sunitinib (Sutent®) in subjects with mRCC and non-clear cell histology. Special emphasis is placed on papillary and chromophobe histologies while sarcomatoid clear cell variants, medullary, and collecting duct carcinomas will be excluded (see eligibility). Subjects may continue receiving study drugs until disease progression, unacceptable toxicities, or withdrawal of consent, for a maximum of 24 months. Continuation of study assigned treatment will be allowed beyond 24 months at the discretion of the sponsor. Stratification variables will include histology (papillary vs. chromophobe) and Motzer risk criteria (0, 1-2, and 3). Tumor progression will be assessed locally and by independent review, in strict accordance with Response Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria measured every 12 weeks. At the time of progression, subjects will be taken off study other than simple administrative mortality follow-up. Primary pathologic samples and plasma/urine angiokine levels at baseline and over time will be collected and stored centrally for biomarker analysis.

Clinical Trial Outcome Measures

Primary Measures

  • Anti-tumor Activity as Measured by Median Progression Free Survival Time
    • Time Frame: 24 Months
    • 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 1.1 criteria. Progressive disease is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

Secondary Measures

  • Progression Free Survival Rates
    • Time Frame: 6, 12 and 24 months
    • 6-, 12-, and 24-month rates of PFS in each arm will be compared for each treatment arm. Progressive disease is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).
  • PFS Expressed in Months
    • Time Frame: 24 months
    • Progression-free survival (PFS) expressed in months as compared to an historic control (interferon-treated clear cell RCC control arm from the sunitinib phase III study). Progressive disease is defined as at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).
  • Overall Response Rate
    • Time Frame: 24 months
    • Defined as complete response [CR] and partial response [PR] by RECIST 1.1 criteria in each treatment arm.Overall Response Rate (ORR) = CR + PR. Complete Response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR) is at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
  • Percentage of Participants With Stable Disease (SD)
    • Time Frame: Baseline to 36 months
    • Percentage of participants with stable disease during treatment is defined as stable disease [SD] by RECIST 1.1 criteria as calculated in each treatment arm. Stable Disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.
  • 12 Week Clinical Benefit Rate as Percentage
    • Time Frame: Baseline to 36 months
    • Rate of complete or partial response or stable disease by the RECIST 1.1 criteria lasting ≥ 12 weeks prior to progression. Benefit rate is defined as complete response [CR] and partial response [PR] and stable disease [SD] by RECIST 1.1 criteria in each treatment arm. Benefit rate = CR + PR + SD. Complete Response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR) is at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.
  • Overall Survival Rates
    • Time Frame: 6, 12, 24, 36 months
    • To compare overall survival (OS) rates at 6, 12, 24, and 36 months and over time in each treatment arm.
  • Best Tumor Shrinkage as a Percentile in Each Arm
    • Time Frame: 24 months
    • To compare the best tumor shrinkage as a percentile in each treatment arm. The percentile change at each follow up visit is calculated by measuring the percentage change in the Sum of lesion measurement from baseline. The best tumor shrinkage is lowest percentile change. A decrease is indicated by a negative percentage.
  • Median Duration of Response (CR, PR, and SD)
    • Time Frame: 24 months
    • To compare the median duration of response (CR, PR, and SD) in each treatment arm. According to RECIST 1.1, Complete Response (CR) is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial Response (PR) is at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.
