Sorafenib in Treating Patients With Metastatic Kidney Cancer That Has Not Responded to Sunitinib or Bevacizumab
RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
PURPOSE: This phase II trial is studying how well sorafenib works in treating patients with metastatic kidney cancer that has not responded to sunitinib or bevacizumab.

Primary Purpose: Treatment
|Official Title:||A Phase II Study of Sorafenib in Patients With Metastatic Renal Cell Carcinoma (RCC) Refractory to SU11248 or Bevacizumab Therapy|
- Tumor Burden Reduction Rate (TBRR) [ Time Frame: at 8 weeks (2cycles of treatment) ]The primary endpoint of the study is defined as the percentage of patients who experience larger than or equal to 5% reduction in tumor burden as measured by RECIST-defined target lesions without progression of non-target lesions or the appearance of any new lesions, confirmed at least 4 weeks after first documentation. RECIST criteria will be used for the purpose of designating target lesions, calculating total tumor burden (the sum of the unidimensional measurement of target lesions) and defining disease progression.Additional RECIST-defined partial or complete responses will be recorded.
- Overall Survival [ Time Frame: followed until progression or death for approximately 3 years ]Overall survival measured in months and summarized using the Kaplan-Meier method. This will be calculated from the date of registration on-study to the dates of documented evidence of progression and death, respectively.
- Time to Progression [ Time Frame: followed to progression for approximately 3 years ]
Time to objective progression will be measured from the start of treatment until the criteria for RECIST-defined progression are met, taking as reference the smallest measurements recorded since the treatment started, including baseline.
Progression-free survival measured in months and summarized using the Kaplan-Meier method.
- Duration of Overall Response (Tumor Burden Reduction) [ Time Frame: followed for overall response for approximately 3 years ]Measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented.

Chemotherapy single agent systemic. Sorafenib given up to 600mg orally every 12 hours for up to 10 months (40 weeks).
Drug: sorafenib tosylate
Sorafenib (BAY 43-9006) is an oral multi-kinase inhibitor targeting both tumor cells and the tumor vasculature. Patients with metastatic RCC meeting eligibility criteria will receive 400 mg BID of sorafenib in a single-arm phase II study. Treatment will be administered on an outpatient basis.
- To determine the tumor burden reduction rate in patients with sunitinib malate- or bevacizumab-refractory, metastatic clear cell renal cell carcinoma treated with sorafenib tosylate.
- To determine the safety of sorafenib tosylate in these patients.
- To record the duration of tumor reduction, time to disease progression, and overall survival of patients treated with sorafenib tosylate.
OUTLINE: Patients receive oral sorafenib tosylate twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
