A Study Evaluating Tarceva in Combination With Avastin Versus Avastin Alone in Treating Metastatic Renal Cell Carcinoma

The primary purpose of the study is to assess the potential benefit of combining two targeted therapies (an anti-EGF inhibitor along with an anti-VEGF inhibitor). The goal will be to determine whether the addition of Erlotinib to Avastin will improve the benefit in metastatic renal cell carcinoma (RCC) with regard to time to progression, response rate, duration of response, and survival compared with Avastin alone. Since Avastin has been shown to be active in renal cancer, the goal will be to assess whether this activity can be enhanced with Erlotinib.

* Pregnancy or breast feeding
* Inability to comply with study and/or follow-up procedures
* History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that might affect the interpretation of the results of the study or render the subject at high risk from treatment complications
* Serious, non-healing wound, ulcer, or bone fracture
* Evidence of bleeding diathesis or coagulopathy
