RAD001 for Patients With Radioiodine Refractory Thyroid Cancer

• RAD001 will be taken once a day in the morning starting on Day 1 and continue until the participant is no longer participating in the study treatment.
• A history and physical exam will be performed the first day of the study and then once a month. Blood tests including coagulation studies, and thyroid studies will be performed monthly. A urine sample will need to be provided on the first day of treatment and then every 2 months. Imaging consisting of a CT or MRI of the neck, chest and abdomen will be done every 8 weeks after starting RAD001.
• Participants will remain on this research study for up to 24 months. However, if the participants doctor feels that they are benefiting from the study drug and they do not have severe side effects, they may be given the option to continue taking RAD001.

• Anaplastic thyroid cancer with disease progression with documented disease progression by modified RECIST within 6 months of study day 1.
