        Inclusion Criteria:

          -  Patients must be 18 years old or older.

          -  ECOG performance status < 2 (Appendix 1).

          -  Patients must have histologically confirmed differentiated thyroid cancer, that is
             metastatic or unresectable and for which standard curative or palliative measures do
             not exist or are no longer effective.

          -  Patients may have received multiple treatments of radioactive iodine. Patients may
             have received one or more prior MKI treatments that are not lenvatinib (note: all
             patients will have been required to have had lenvatinib for entry, see below). At
             least 4 weeks must have elapsed since prior non-lenvatinib MKI treatment.

             have had documented progression while on the prior treatment with lenvatinib and must
             have had a minimum of stable disease for 4 months.

          -  Measurable disease defined as at least one malignant lesion that can be accurately and
             serially measured in at least one dimension (longest diameter to be recorded) using
             conventional methods (CT, MRI, x-ray, PE) (diameter > 20 mm) or spiral CT (diameter >
             10 mm).

          -  Life expectancy greater than 3 months.

          -  Serum creatinine < 1.5 times ULN, or 24-hour creatinine clearance > 75 cc/min. (Note:
             creatinine clearance need not be determined if the baseline serum creatinine is within
             normal limits).

          -  Serum bilirubin < 2.0mg/dL; ALT and AST < 2.5 ULN;

          -  INR < 2.0 or a PT/PTT within normal limits. Exception allowed for patients receiving
             anti-coagulation treatment with an agent such as warfarin or heparin who may be
             allowed to participate. For patients on warfarin, the INR should be measured prior to

             performed on-study as long as the lymph nodes are not followed as part of RECIST
             criteria and all study medications are held from three days prior to the procedure to
             one week following or until deemed safe by the treating physician

          -  Patients with carcinomatous meningitis are excluded from the study. Patients with
             treated sites of leptomeningeal disease may be included at the discretion of the
             principal investigator.

          -  Patients who are not expected to tolerate a starting dose of 18mg lenvatinib and 5mg
             everolimus daily will not be considered eligible for the study.

             indicated is allowed as long as it is not evidence of progressive disease and is not
             required to be measured as a target lesion per RECIST Biological response modifiers,
             such as G-CSF, within 3 week prior to study entry. (G-CSF and other hematopoietic
             growth factors may be used in the management of acute toxicity such as febrile
             neutropenia when clinically indicated or at the discretion of the investigator;
             however they may not be substituted for a required dose reduction).
