Phase II Study of Afinitor vs. Sutent in Patients With Metastatic Non-Clear Cell Renal Cell Carcinoma

Phase 2

Completed

• Conditions: Advanced Non-clear Cell Renal Cell Carcinoma
• Interventions: Drug: Everolimus; Drug: Sunitinib

• Registration Number: NCT01108445
• Lead Sponsor: Duke University

Brief Summary

To compare the anti-tumor activity of everolimus and sunitinib in subjects with metastatic renal cell carcinoma (mRCC) with non-clear cell pathology.

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.

Arm && Interventions

Group	Intervention	Description
RAD001	Everolimus	Subjects in this treatment arm will receive everolimus/RAD001 10 mg orally once daily by mouth on days 1 through 42 for each 42 day cycle.
Sunitinib	Sunitinib	Subjects in this treatment arm will take sunitinib 50 mg daily by mouth on days 1 through 28 of each 42 day cycle.

Primary Outcome Measures

Name	Time	Method
Anti-tumor Activity as Measured by Median Progression Free Survival Time	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 Outcome Measures

Name	Time	Method
Overall Response Rate	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.
Progression Free Survival Rates	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	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 Survival Rates	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.
Percentage of Participants With Adverse Events	24 months	To assess toxicities associated with everolimus or sunitinib using NCI CTC version 4.0 criteria
Change in Quality-of-life	baseline, up to 40 months	To compare change in quality-of-life, as measured by the FACT-KSI scale at baseline and end of treatment per subject in each treatment arm. Functional Assessment of Cancer Therapy Kidney Symptom Index. FKSI is a questionnaire for FACT-Kidney Symptom Index used to assess QoL/participant-reported outcomes for participants diagnosed with renal cell cancer. The FKSI contained 15 questions each ranging from 0 (not at all) to 4 (very much) so that FKSI ranged between 0-60 where higher scores reflects better functioning and fewer symptoms.
Percentage of Participants With Stable Disease (SD)	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	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.
Best Tumor Shrinkage as a Percentile in Each Arm	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)	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.
Median OS	Up to 40 months	To compare the median OS in each treatment arm.
Time-to-new Metastatic Disease in Each Treatment Arm	36 months	To compare the time-to-new metastatic disease in each treatment arm, defined from the date of first study agent administration to the onset of a new evaluable site of disease, excluding the primary site and all sites documented at baseline
