This early-phase trial tests a single infusion of genetically modified immune cells (CAR-T cells) in 4 people with refractory Graves' disease, a thyroid condition that doesn't respond well to standard medication. The cells target two proteins (CD19 and BCMA) to reset the immune s…

This pilot study will test the safety of thyroid artery embolization (TAE) in 10 UK patients with benign thyroid nodules or goitre. TAE is a minimally invasive procedure that blocks blood flow to the thyroid gland using tiny particles, causing it to shrink. The goal is to see if …

This study tests a computer model called OptiThyDose that helps doctors find the best dose of thyroid medication for children with congenital hypothyroidism or Graves' disease. The model uses past lab results to keep thyroid hormone levels in a healthy range. About 150 children w…

This study tests whether an artificial intelligence (AI) model can accurately diagnose thyroid eye disease, assess its activity and severity, and predict its outcome using specialized MRI scans of the eye socket. Researchers will enroll 1200 people, including patients with thyroi…

This study tests a software called Glandy HYPER that uses artificial intelligence to detect thyrotoxicosis—a dangerous overactive thyroid state—in people with Graves' disease. The AI analyzes resting heart rate data from wearable devices like smartwatches and compares it with sta…

This study tests a new imaging method called Al18F-NOTA-FAPI-04 PET/CT or PET/MRI to see if it can better detect and guide treatment for malignant tumors, heart problems, and autoimmune diseases like hyperthyroidism. About 600 adults will receive the imaging agent and be monitore…
