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.

Inclusion Criteria:

- Histologically confirmed locally advanced or metastatic thyroid cancer, excluding
thyroid lymphomas not amenable to or refractory to surgical resection, external beam
radiotherapy, radioiodine or other local therapies.

- Prior therapy with chemotherapy and targeted therapies except for mTor inhibitors is
allowed.

- Medullary thyroid cancer with documented evidence of disease progression by modified
RECIST within 6 months before study day 1 or symptomatic disease at the time of
screening in the absence of documented disease progression.

- Differentiated thyroid cancer with documented evidence of disease progression by
modified RECIST within 6 months before study day 1.

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

- Patients must have at least one measurable site of disease according to RECIST
criteria that has not previously irradiated. If the patient has has previous radiation
to the marker lesion(s), there must be evidence of progression since radiation.
