Once the maximum tolerated dose has been established for this regimen a dose expansion of 20 patients with metastatic RCC will be undertaken. Up to 10 patients with a positive FDG- PET scan at baseline (defined by 1 or more target lesions demonstrating an SUV > 5.0) will begin treatment per Figure 2B. Patients 1-10 will begin Sunitinib on Day 0 and begin RAD001 on Day 14 after repeat FDG-PET scan. Patients 11-20, will have a 2 week lead-in period of RAD001 and will begin Sunitinib 2 weeks later on Day 0. After repeat FDG-PET scan. Both groups of patients will repeat PET scan at Day 14 of cycle 2. Patients with negative FDG PET scans (SUV < 5.0 in all lesions) will not undergo repeat scanning. Patients will undergo evaluations for tumor response every 12 weeks with appropriate measurement studies (CT, MRI, bone scan). In the setting of a mixed response (progressive disease in 1 or more lesions but continued regression or stable disease below baseline in other lesions) patients may continue on study if it is determined by the PI, treating physician and patient that there is ongoing clinical benefit to the patient.
