• Expansion Cohort Only: Participants must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension at 20mm or greater with conventional techniques or as 10mm or greater with spiral CT.
• Expansion Cohort Only: Previously treated with at least one anti-angiogenic agent, including but not limited to bevacizumab, sunitinib, or sorafenib. No more than 4 lines of prior systemic therapy for kidney cancer, mTOR pathway inhibitors other than RAD001 are allowed.

• Life expectancy of greater than 3 months
• ECOG performance status of 0 or 1
• Normal organ and marrow function as outlined in the protocol
• Able to swallow oral medications

• History of malabsorption syndrome, disease significantly affecting gastrointestinal function or major resection of stomach or small bowel that could interfere with absorption, distribution, metabolism, or excretion of study drugs
• Any ongoing toxicity from prior anti-cancer therapy that is greater than grade 1 and/or that is progressing in severity.
