Summary:

      The purpose of this study is to find out what effects, good and/or bad, the combination of
      sorafenib and temsirolimus will have on thyroid cancer. Treatment guidelines from the
      National Comprehensive Cancer Network include sorafenib as a treatment option for thyroid
      cancer.

      Temsirolimus is an intravenous medication that is FDA approved for other type of cancers. In
      laboratory studies, the addition of temsirolimus to sorafenib works better than sorafenib
      alone.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Patients must have histopathologically confirmed at MSKCC thyroid carcinoma of
             follicular cell origin (D-TC-FCO), which includes papillary, follicular, Hürthle cell
             histology, or anaplastic along with their respective variants.

          -  Available pathology for RAF mutational testing (e.g., paraffin block or 5-10 unstained
             slides). It is not required that mutational testing be completed before starting the
             clinical study.

          -  Patients must have surgically inoperable and/or recurrent/metastatic disease.

          -  Patients must have a PET scan prior to the protocol start date and have at least one
             FDGavid lesion that has not been removed surgically or radiated (unless it has
             progressed by RECIST criteria after the completion of radiation therapy and is still
             FDG-avid). FDGavidity will be defined as any focus of increased FDG uptake greater
             than normal activity with SUV maximum levels greater than or equal to 3. PET scan can
             have been done at any time prior to the start of therapy, although it is recommended
             that it be done within 3 months prior to the start of therapy.

          -  Patients must have measurable disease by RECIST criteria, defined as at least one
             lesion that can be accurately measured in at least one dimension (longest diameter to
             be recorded) as ≥ 20 mm with conventional techniques or as ≥ 10 mm with spiral CT
             scan; performed ≤ 4 weeks of protocol start date.

          -  Patients must have progressive disease defined by at least one of the following
             occurring during or after previous treatment (including RAI treatment):

          -  The presence of new or progressive lesions on CT/MRI.

          -  New lesions on bone scan or PET scan.

          -  Rising thyroglobulin level (documented by a minimum of three consecutive rises, with
             an interval of > 1 week between each determination).

          -  Prior RAI therapy is allowed if > 3 months prior to initiation of therapy on this
             protocol and evidence of progression (as defined above) has been documented in the
             interim. A diagnostic study using <10 mCi of RAI is not considered RAI therapy.

          -  Patients may have received prior external beam radiation therapy to index lesions ≥ 4
             weeks prior to initiation of therapy on this protocol if there has been documented
             progression by RECIST criteria. Prior external beam radiation therapy to the non-index
             lesions is allowed if ≥ 4 weeks prior to initiation of therapy on this protocol.

          -  ECOG performance status ≤ 2 (or Karnofsky performance status ≥ 60%).

          -  Patients must have normal organ and marrow function as defined below:

          -  Absolute neutrophil count ≥1,500/mcL

          -  Platelets ≥100,000/mcL

          -  Total bilirubin ≤ 1.5 X institutional ULN

          -  Creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above 1.5
             X institutional ULN [in this circumstance, either of a measured level based on a 24
             hour urine collection, or a calculated level using the Cockcroft and Gault equation:
             (140 - age in years) X (weight in kg) X (0.85 if female)/72 X serum Cr may be used].

          -  International normalized ratio (INR) ≤ 1.5 (or in range INR, usually between 2 and 3,
             if patient is on a stable dose of therapeutic warfarin).

          -  While the use of Angiotensin-Converting Enzyme (ACE) inhibitors is not absolutely
             excluded, efforts should be made to see if patients on ACE inhibitors can be taken off
             the medication or switched to another medication.

             carbamazepine, phenytoin, barbiturates, rifabutin, rifampicin, and St. John's Wort.
             Potential CYP3A inhibitors include protease inhibitors, antifungals, macrolide
             antibiotics, nefazodone, and selective serotonin inhibitors.
