About
This phase II trial studies how well iodine I-131 works with or without selumetinib in treating patients with thyroid cancer that has returned (recurrent) or has spread from where it started to other places in the body (metastatic). Many thyroid cancers absorb iodine. Due to this, doctors often give radioactive iodine (iodine I-131) alone to treat thyroid cancer as part of standard practice. It is thought that the more thyroid tumors are able to absorb radioactive iodine, the more likely it is that the radioactive iodine will cause those tumors to shrink. Selumetinib may help radioactive iodine work better in patients whose tumors still absorb radioactive iodine. It is not yet known whether iodine I-131 is more effective with or without selumetinib in treating thyroid cancer.
Full description
PRIMARY OBJECTIVE:
I. To determine the response rate at 6 months following treatment with 131I (iodine I-131) in combination with placebo or selumetinib for radioactive iodine-avid (RAIA) recurrent and/or metastatic thyroid cancer.
SECONDARY OBJECTIVES:
I. To determine the best overall response following treatment with 131I in combination with placebo or selumetinib for RAIA recurrent and/or metastatic thyroid cancer.
II. To compare the progression-free survival of patients with RAIA recurrent and/or metastatic thyroid cancer treated with 131I in combination with placebo or selumetinib.
III. To compare serum thyroglobulin changes for patients with RAIA recurrent and/or metastatic thyroid cancer treated with 131I in combination with placebo or selumetinib.
IV. To evaluate the safety and tolerability of 131I in combination with placebo or selumetinib for patients with RAI-avid recurrent and/or metastatic thyroid cancer.
CORRELATIVE OBJECTIVE:
I. To explore the genomic and transcriptomic landscape of RAIA tumors for signatures that correlate to therapeutic benefit achieved with 131I in combination with placebo or selumetinib.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive selumetinib orally (PO) twice daily (BID) starting on week 1, day 1 and continuing through 2 days after iodine I-131 therapy has been administered. Approximately 3 weeks after beginning treatment with selumetinib, patients receive iodine I-131 PO.
ARM II: Patients receive placebo PO BID starting on week 1, day 1 and continuing through 2 days after iodine I-131 therapy has been administered. Approximately 3 weeks after beginning treatment with placebo, patients receive iodine I-131 PO.
After completion of study treatment, patients are followed up at 1 and 3 months, every 3 months for 12 months, and then every 6 months for 2 years.

Inclusion criteria
NOTE 1: Modification of the RECIST v1.1 measurable disease criteria includes a change in the definition of what is considered a measurable malignant lymph node; a malignant lymph node is considered measurable if any of the following apply:
It is noted to be RAI-avid on radioactive iodine imaging (diagnostic or post-therapy whole body scans acceptable) and it measures >= 1 cm in the long axis,
It is pathologically proven to be involved with thyroid cancer (by cytology or pathology) and it measures >= 1 cm in the long axis, or
Its short axis is >= 1.5 cm when assessed by computed tomography (CT) scan NOTE 2: Patients only with biochemical evidence of disease without structural evidence of cancer are not eligible for this study
Undetectable thyroglobulin antibody AND
A serum thyroglobulin of 10 ng/ml or greater in the context of suppressed thyroid-stimulating hormone (TSH) (TSH =< 0.4 mcU/ml) =< 28 days prior to study registration; use of any thyroglobulin assay is allowed, though all serum thyroglobulin measurements for study purposes must be conducted with the same thyroglobulin assay
Note: during the Active Monitoring Phase of a study (i.e., active treatment and observation), participants must be willing to return to the consenting institution for follow-up
Exclusion criteria
131I therapy =< 6 months prior to registration; Note: 131I administered solely for diagnostic purposes is not considered 131I therapy
External beam radiation therapy =< 28 days prior to registration; note: previous treatment with radiation is allowed if the investigator judges it will not compromise patient safety on the study
Having been treated with a total cumulative (lifetime) 131I therapeutic activity > 800 mCi (excluding 131I activity administered for diagnostic scans)
Treatment with chemotherapy or targeted therapy (e.g. tyrosine kinase inhibitor) =< 28 days prior to registration
Prior exposure to mitogen-activated protein kinase kinase (MEK), RAS, or RAF inhibitors (note: previous exposure to sorafenib is allowed) OR history of hypersensitivity to selumetinib, thyrotropin alpha (Thyrogen), or any excipient agents
Unresolved toxicity > Common Terminology Criteria for Adverse Events (CTCAE) grade 2 from previous anti-cancer therapy, except for alopecia
Cardiac conditions as follows:
Ophthalmological conditions as follows:
Symptomatic or untreated leptomeningeal disease, brain metastasis, or spinal cord compression
Unable to follow a low iodine diet or requiring medication with high content in iodide (e.g., amiodarone)
Received iodinated intravenous contrast within =< 2 months of registration; avoidance of iodinated oral contrast is also preferred but not strictly required for study enrollment; NOTE: those who have had iodinated intravenous contrast within this time frame may still be eligible if a urinary iodine analysis reveals that excess iodine has been cleared (defined as urinary iodine documented to be < 300 mcg/day by either a spot urinary iodine or 24-hour urinary iodine measurement)
Any of the following:
Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
Immunocompromised patients and patients known to be human immunodeficiency virus (HIV) positive and currently receiving antiretroviral therapy; NOTE: patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, hepatitis B infection, hepatitis C infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm. (NOTE: Performance of investigational 124I PET/CT scans is allowed prior to and during conduct of this study)
Other active malignancy =< 2 years prior to registration that will interfere with conduct of this trial; EXCEPTIONS: non-melanotic skin cancer or carcinoma-in-situ of the cervix; NOTE: if there is a history of prior malignancy, patients must not be receiving other specific treatment (chemotherapy, hormonal therapy, radiation) for their cancer
Not willing to discontinue use of supplemental vitamin E
