This phase II trial studies how well lenvatinib works when given together with standard of care iodine I-131 in treating patients with radioactive iodine-sensitive differentiated thyroid cancer. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.


I. Evaluate the efficacy of lenvatinib pretreatment along with radioactive iodine (RAI) in patients with previously treated RAI sensitive thyroid cancer.

I. Demonstrate the safety of the combination of lenvatinib and RAI in patients with Iodine sensitive differentiated thyroid carcinoma (DTC).
II. Assess dynamic changes in established serum based biomarkers of DTC (thyroglobulin [Tg] and Tg antibody).
III. Explore the utility of protein and genetic biomarkers to predict treatment efficacy.

Patients receive lenvatinib orally (PO) once daily (QD) for 8 weeks and up to 12 weeks in the absence of disease progression or unaccepted toxicity. Patients also receive iodine I-131 PO daily as standard of care.

After completion of study treatment, patients are followed up within 6 weeks, every 3 months for 1 year, and then periodically thereafter.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
