Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Thyroid ophthalmopathy, also known as thyroid eye disease or Graves' ophthalmopathy, is a condition characterized by inflammation and swelling of the tissues around the eyes, often accompanied by protrusion of the eyeballs. This condition can lead to significant discomfort, visual disturbances, and in severe cases, permanent vision loss.

Primary treatment modalities are intravenous methylprednisolone (IVMP) and other medications for patients with moderate to severe and active thyroid eye disease. In addition, external beam radiation therapy (ERT) is an another treatment option in combination with IVMP.

Radiation therapy delivers targeted doses of ionizing radiation to the affected orbital tissues, effectively reducing inflammation. This approach is particularly beneficial for patients who may not respond adequately to steroid therapy alone or those who experience recurrent disease flares.

This study will test the efficacy of a shortened treatment regimen comprising 5 sessions of ERT to a standard protocol of 10 treatments. The primary aim is to ascertain the effectiveness of shorted radiation treatment while improving patients' quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The research methodology of this study involves comparing the standard protocol of 10 radiation treatments with a modified approach comprising 5 treatments of daily External Beam Radiation Therapy (ERT).

The primary objective of this investigation is to assess whether reducing the number of radiation treatments while maintaining the effectiveness of the therapy can lead to improvements in the quality of life for patients with thyroid ophthalmopathy.

By comparing these two treatment regimens, researchers aim to evaluate the efficacy and safety of the abbreviated radiation schedule in managing the symptoms and progression of the disease.

Participants enrolled in the study will be randomized into two groups: one receiving the standard 10 treatments and the other receiving the modified 5-treatment regimen of daily ERT. Throughout the study period, participants will undergo comprehensive assessments to monitor changes in symptoms, vision, and quality of life. These evaluations will include ophthalmic examinations, imaging studies, and patient-reported outcome measures to capture both objective and subjective measures of treatment response.
