Brief summary:
This phase II trial is studying how well selumetinib works in treating patients with papillary thyroid cancer that did not respond to radioactive iodine. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description:
PRIMARY OBJECTIVES:

I. Ascertain the objective response rate (complete response and partial response) in patients with iodine I 131-refractory papillary thyroid cancer treated with selumetinib.

SECONDARY OBJECTIVES:

I. Determine the toxicity of this treatment in these patients. II. Determine the pharmacokinetic profile of this treatment in these patients. III. Determine the progression-free and overall survival of these patients. IV. Assess proxy measures of treatment response (thyroglobulin and PET scan) in patients treated with selumetinib.

IV. Compare relevant laboratory correlates between responders and non-responders.

OUTLINE: This is a multicenter study.

Patients receive oral selumetinib twice daily on days 1-28. Treatment repeats every 28 days in the absence of unacceptable toxicity or disease progression.

Archived tissue is examined for gene mutations, including RET, BRAF, NTRK, and RAS, by fluorescence in situ hybridization and/or polymerase chain reaction and fluorescence melting curve analysis. Protein expression of ERK and phosphorylated ERK is assessed by immunohistochemical staining.

Blood samples are collected periodically for pharmacokinetic analysis and biomarker assessment (thyroglobulin and antithyroglobulin autoantibodies).

After completion of study therapy, patients are followed periodically for up to 2 years.

Arms:
arm 1: Patients receive oral selumetinib twice daily on days 1-28. Treatment repeats every 28 days in the absence of unacceptable toxicity or disease progression.

Interventions: intervention 1: Laboratory Biomarker Analysis intervention 2: Selumetinib
Intervention descriptions: intervention 1: Correlative studies intervention 2: Selumetinib was administered orally as a free base suspension at a dose of 100 mg twice daily for 28-day cycles. Those participants experiencing Common Terminology Criteria for Adverse Events (CTCAE) v3.0 grade 3 toxicity or worse had their dose reduced to 50 mg twice daily and then to 50 mg once daily, if necessary.
