Primary outcomePrimary: Objective Response Rate (ORR) Evaluated Using Response Evaluation Criteria in Solid Tumors (RECIST) — 30; 25 percentage of participants
Summary
This randomized phase II trial is studying sorafenib and interferon alfa-2b to see how well they work compared to sorafenib alone in treating patients with metastatic kidney cancer. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Interferon alfa-2b may interfere with the growth of tumor cells. Sorafenib and interferon alfa-2b may also block blood flow to the tumor. Giving sorafenib together with interferon alfa-2b may kill more tumor cells.

Eligibility Criteria
Inclusion Criteria
- Patients with histologically or cytologically confirmed metastatic clear cell RCC
- Patients must have measurable disease, defined as a lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) and measures >= 20 mm with conventional techniques or >= 10 mm with spiral CT scan
- ECOG performance status = = 1,500/μL
- Platelets >= 100,000/μL
- Hgb > 9.0 g/dL (may be transfused or receive epoetin alfa [e.g., Epogen®] to maintain or exceed this level)
- Total bilirubin = 3.0 g/dL
- Serum creatinine = = 1.5 is due to warfarin therapy; other patients with an INR >= 1.5 are excluded
- Patients must not have a history of severe depression
- Concomitant treatment with rifampin, St. John's wort, and the cytochrome p450 enzyme-inducin antiepileptic drugs (phenytoin, carbamazepine or Phenobarbital)
