This phase II trial studies the effects, good and bad, of using everolimus along with sorafenib versus sorafenib alone in treating patients with thyroid cancer that has spread to other places in the body (advanced) or cannot be removed by surgery (unresectable) and has not responded to treatment with radioactive iodine (refractory). Sorafenib and everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The addition of everolimus to sorafenib may cause more shrinkage of thyroid cancer and may prevent it from growing but it could also cause more side effects than sorafenib alone. It is not yet known whether this treatment with sorafenib and everolimus is better, the same, or worse than sorafenib alone.

PRIMARY OBJECTIVE:
I. To compare the progression-free survival (PFS) between sorafenib tosylate (sorafenib) and everolimus versus (vs.) sorafenib alone in patients with radioactive iodine refractory Hurthle cell thyroid cancer.
SECONDARY OBJECTIVE:
I. To compare the confirmed response rate, overall survival (OS), and adverse event rates between sorafenib and everolimus vs. sorafenib alone.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive sorafenib tosylate orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients with progressive disease may then receive everolimus PO once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive sorafenib tosylate as in Arm I and everolimus PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 2-6 weeks and then every 3-6 months for up to 5 years after registration.
