Spots Global Cancer Trial Database for Iodine I-131 With or Without Selumetinib in Treating Patients With Recurrent or Metastatic Thyroid Cancer

Study Description

Brief Summary: 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.

Detailed 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.
