Study Overview
Brief Summary
Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for their growth or by blocking blood flow to the tumor. Interferon alfa may interfere with the growth of tumor cells and slow the growth of kidney cancer. Sorafenib may help interferon alfa kill more tumor cells by making tumor cells more sensitive to the drug. Giving sorafenib together with interferon alfa may kill more tumor cells. This phase II trial is studying how well giving sorafenib with interferon alfa works in treating patients with locally advanced or metastatic kidney cancer.
Detailed Description
PRIMARY OBJECTIVES:
I. Determine the feasibility and tolerability of sorafenib and interferon alfa in patients with locally advanced or metastatic renal cell carcinoma.
II. Determine the response rate (complete response and partial response) in patients treated with this regimen.
SECONDARY OBJECTIVES:
I. Determine the progression-free survival and response duration of patients treated with this regimen.

Outcomes
Primary Outcomes
Overall response rate (CR+PR) using RECIST criteria
Time Frame: Up to 5 years
CR+PR rate will be calculated with exact 90% confidence intervals.
Grade 3+ toxicities assessed using NCI CTCAE version 3.0

Toxicities will be tabulated by type and grade. Toxicity rates will be calculated with exact 90% confidence intervals.
Progression-free survival
Time Frame: Up to 5 years
Kaplan-Meier curves will be used.
Overall survival
Time Frame: Up to 5 years
Kaplan-Meier curves will be used.
Duration of response
Time Frame: 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 , assessed up to 5 years
Kaplan-Meier curves will be used.
