Randomized Double-Blind Phase II Study of Radioactive Iodine (RAI) in Combination With Placebo or Selumetinib for the Treatment of RAI-Avid Recurrent/Metastatic Thyroid Cancers

This randomized phase II trial studies how well iodine I-131 works with or without
selumetinib in treating patients with thyroid cancer that has returned or has spread from
where it started to other places in the body. 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.

PRIMARY OBJECTIVES:

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.

TERTIARY OBJECTIVES:

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:

- Diagnosis of recurrent and/or metastatic thyroid cancer

- Histological or cytological confirmation of thyroid carcinoma of follicular origin
(including papillary, follicular, or poorly differentiated subtypes and their
respective variants); NOTE: medullary and anaplastic thyroid cancers are excluded;
Hurthle cell carcinomas are excluded (defined as having an invasive tumor composed of
> 75% oncocytic [Hurthle] cells lacking the nuclear features of papillary carcinoma,
tumor necrosis, and marked mitotic activity); patients with oncocytic (Hurthle cell)
variants of papillary thyroid carcinoma (defined as a tumor composed of a majority of
oncocytic [Hurthle] cells having the nuclear features of papillary carcinoma) are
eligible to participate

- RAI-avid lesion on a radioiodine scan (a diagnostic, post-therapy, or post-ablation
scans) performed =< 24 months prior to registration, which suggests that therapy with
131I is justifiable in the judgment of the investigator

- Clinically or radiographically evident structural disease; patients with measurable
disease and those with only non-measurable (?non-target?) structural disease
(according to modified Response Evaluation Criteria in Solid Tumors [RECIST] version
[v] 1.1 criteria) are eligible;

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

- For patients with non-measurable, structural disease the following must apply:

- 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

- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1 or 2

- Able to swallow and retain orally-administered medication with no clinically
significant gastrointestinal abnormalities that may alter absorption

- Absolute neutrophil count (ANC) >= 1500/mm^3 (obtained =< 28 days prior to
randomization)

- Platelet count >= 100,000/mm^3 (obtained =< 28 days prior to randomization)

- Hemoglobin > 9.0 g/dL (obtained =< 28 days prior to randomization)

- Total bilirubin =< 1.5 x upper limit of normal (ULN) (obtained =< 28 days prior
to randomization)

- Aspartate transaminase (AST) =< 2.5 x ULN (or =< 5 x ULN in presence of liver
metastases) (obtained =< 28 days prior to randomization)

- Creatinine =< 1.5 mg/dL OR calculated creatinine clearance of >= 50 ml/min by
either the Cockcroft-Gault formula or 24-hours urine collection analysis
(obtained =< 28 days prior to randomization)

- Negative pregnancy test performed =< 7 days prior to registration for women of
childbearing potential only

- Provide informed written consent

- Willing to return to enrolling institution for follow-up (during the Active
Monitoring Phase of the study)

- 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

- Willing to provide mandatory archival tumor tissue (block or minimum of 30
unstained slides from a primary or recurrent/metastatic thyroid cancer) for
correlative research purposes; NOTE: patients with less archival tumor tissue
available may still be eligible for the study after discussion with Academic and
Community Cancer Research United (ACCRU); receipt of archival tumor tissue is not
required for study registration and initiation of therapy

- Willing to provide mandatory blood samples for correlative research purposes

Exclusion Criteria:

- 131I therapy =< 6 months prior to registration; Note: 131I administered solely for
diagnostic purposes is not considered 131I therapy

treatment with radiation is allowed if the investigator judges it will not compromise
patient safety on the 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
