This phase II trial studies the side effects and how well pazopanib hydrochloride works in treating patients with advanced thyroid cancer. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stopping blood flow to the tumor.

Primary Outcome Measures:
  • Confirmed tumor response (DTC expanded cohort) [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Tumor response (complete or partial response) as assessed by RECIST criteria noted as objective status on 2 consecutive evaluations at least 8 weeks apart for patients with DTC who are thyroglobulin antibody negative.

  • Proportion of patients who have achieved an objective response to the study agent [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Objective response as assessed by Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

Secondary Outcome Measures:
  • Biomarker-based response [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Rates will be summarized assuming they are binomially distributed, and the biomarker levels themselves will be explored both quantitatively and graphically before and after treatment

  • Duration of response [ Time Frame: From the date of documentation of response (PR or CR) until the date of progression or last follow-up (whichever comes first) in the subset of patients with confirmed response, assessed up to 3 years ] [ Designated as safety issue: No ]
  • Incidence of toxicity [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Toxicity will be assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.

  • Overall survival [ Time Frame: Time from registration to date of last follow-up or death due to any cause, assessed up to 3 years ] [ Designated as safety issue: No ]
    Estimated using the method of Kaplan-Meier.

  • Proportion of patients achieving a biochemical response in appropriate tumor markers [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Levels of free VEGF and PDGF will be explored in a graphical manner in pre-treatment and multiple on-treatment samples.

  • Proportion of patients in which the radioactive iodine scan have changed from "no uptake" to "any uptake" [ Time Frame: At 6 months (at 3 months for patients with ATC) ] [ Designated as safety issue: No ]
  • Proportion of patients with differentiated thyroid cancer (DTC) and medullary thyroid cancer (MTC) who have not failed treatment at 6 months (3 months for anaplastic thyroid cancer [ATC]) [ Time Frame: Up to 6 months ] [ Designated as safety issue: No ]
    The proportion of patients who have not failed treatment due to disease progression, adverse reactions, refusal for further participation, or who went on to alternate therapy at 6 months (3 months for ATC patients) will be calculated and summarized independently within each of the patient groups. Assuming that the incidence of response is binomially distributed, 90% binomial confidence intervals will also be calculated.

  • Time to subsequent therapy [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
    Estimated using the method of Kaplan-Meier.

  • Time to treatment failure [ Time Frame: Time from registration to the date the patient discontinues treatment, assessed up to 3 years ] [ Designated as safety issue: No ]
    Estimated using the method of Kaplan-Meier.

  • Times to progression [ Time Frame: Time from registration to the date of progression or last follow-up, whichever comes first, assessed up to 3 years ] [ Designated as safety issue: No ]
    Time to progression will be estimated using the method of Kaplan-Meier. In addition, the 6-month progression-free rate will be evaluated using the 6-month rates and associated confidence intervals. Competing risk analyses may be done to evaluate time to progression, allowing for going on to alternate treatment or death prior to progression as competing risks.

Other Outcome Measures:
  • Change in blood markers for angiogenesis [ Time Frame: Baseline to up to 3 years ] [ Designated as safety issue: No ]
    Blood markers for angiogenesis including levels of free VEGF, free GW786034, and GW786034/VEGF complexes will be evaluated before and during therapy. Changes in these levels will largely be explored in a graphical manner as well as exploring any potential relationships between these levels and clinical outcome such as response or progression-free rate and toxicity incidence.

  • Receiving cytochrome P450 (CYP) interactive concomitant medications; certain medications that act through the CYP450 system are specifically prohibited in patients receiving GW786034 (pazopanib) because in vitro data indicate that the agent has the potential to interact with the cytochrome P450 isoenzymes cytochrome P450, family 2, subfamily C, polypeptide 9 (CYP2C9) and cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4); certain other agents should be used with caution

    • Poorly controlled depression or anxiety disorder, or recent (=< 6 months) suicidal ideation
  • Known active and/or untreated brain metastases and/or brain metastases requiring ongoing therapy (e.g. corticosteroids); NOTE: (because of the poor prognosis often associated with brain metastases and because of the potential risk of bleeding in active brain metastases associated with multi-targeted tyrosine kinase inhibitor therapy, patients with active and/or untreated brain metastases and/or those with brain metastases requiring ongoing therapy - e.g. corticosteroids - are excluded from trial enrollment; enrollment will, however, be permitted in cases of patients with longstanding treated and inactive brain metastases not requiring ongoing therapy, providing that stability of brain metastases has been demonstrated for a period of 3 months or greater as assessed by intracranial imaging - and providing that there is no indication of increased vascularity of the treated metastases by magnetic resonance imaging (MRI) imaging conducted =< 14 days prior to registration; when questions arise related to these criteria, the PI of the trial, Dr. Keith Bible, should be contacted for assistance on eligibility)

  • Receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of GW786034 (pazopanib); NOTE: the eligibility of patients will be determined following review of their case by the Principal Investigator; efforts should be made to switch patients who are taking enzyme-inducing anticonvulsant agents to other medications
  • Receiving any concomitant medications that are associated with a risk of QTc prolongation and/or Torsades de Pointes; NOTE: these medications should be discontinued or replaced with drugs that do not carry these risks, if possible
