Heat therapy plus pills could tame overactive thyroid
NCT ID NCT07557810
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new approach for treating hyperthyroidism (overactive thyroid) by combining a minimally invasive heat procedure with standard medication. About 454 adults with hyperthyroidism will receive thermal ablation to destroy overactive thyroid tissue, plus antithyroid drugs to control hormone levels. The goal is to see if this combination can better control symptoms, reduce drug side effects, and improve quality of life compared to medication alone.

Who is studied
The population receiving thermal ablation combined with antithyroid drug therapy for hyperthyroidism primarily includes patients diagnosed with hyperthyroidism (e.g., Graves' disease, toxic multinodular goiter, or toxic adenomas). These patients typically choose this combined approach due to inadequate response or intolerance to antithyroid drugs alone, refusal of radioactive iodine, or unsuitability/unwillingness for surgery. The combined strategy aims to ablate hyperfunctioning tissue while maintaining stable thyroid function with medication, preserving normal glandular tissue, avoiding lifelong replacement therapy, and achieving minimal scarring, rapid recovery, and short hospitalization. Candidates generally have moderate thyroid volumes and localized lesions amenable to ultrasound-guided ablation.

Inclusion Criteria: * Patients diagnosed with primary hyperthyroidism based on clinical manifestations and laboratory findings; * Patients whose basal metabolic rate (BMR) remains within ±20% of the normal reference range, and whose resting heart rate is controlled at ≤90 beats/min; * Patients with inadequate response to standard antithyroid drug (ATD) therapy, those experiencing severe adverse reactions to ATDs, those unsuitable for or unresponsive to radioactive iodine (RAI) therapy, or those who decline conventional surgical resection and wish to undergo ablation combined with medication to shorten the treatment course and achieve rapid improvement of hyperthyroid symptoms, including patients with mild, moderate, or severe disease; * Patients with concomitant moderate-to-severe Graves' ophthalmopathy (GO); * Patients with a safe needle trajectory for ablation access; * Patients who are able to understand the purpose of the study, voluntarily participate, and provide written informed consent. Exclusion Criteria: * Severe coagulopathy; * Poor general condition, such as concomitant severe cardiac, hepatic, renal, or other major organ dysfunction; * Substernal goiter or a thyroid gland largely located in the retrosternal space (relative contraindication; staged treatment may be considered); * Patients with malignant exophthalmos in whom the condition may worsen post-procedure; * Patients with significant tracheal compression requiring urgent decompression; * Unilateral vocal cord dysfunction confirmed by laryngoscopy; * Women in the first or third trimester of pregnancy, lactating women, or those planning pregnancy in the near future.
