AI-Based Wearable Monitoring (Glandy HYPER) for Antithyroid Drug Dose Adjustment in Graves' Disease

Graves' disease is the most common cause of hyperthyroidism and is usually treated with antithyroid drugs such as methimazole (MMI). The MMI dose is adjusted according to periodic blood tests, but individual responses vary, so some patients remain hyperthyroid longer than necessary while others become hypothyroid from overtreatment. Glandy HYPER is a CE-marked, AI-based software medical device that analyzes sleep heart rate data collected by a smartwatch, together with thyroid function test results, to provide daily information on thyrotoxicosis status. This exploratory, post-market, two-center, randomized, open-label study in Germany evaluates whether MMI dose adjustment supported by Glandy HYPER shortens the time to normalization of free T4 compared with standard care, and also assesses overtreatment, thyroid-related quality of life, and safety.

Trial to Evaluate the Efficacy of a Zinc, Selenium, and L-Tyrosine Supplement in the Prevention of Thyrotoxicosis in Subjects With r25191G/A SEPP1 Polymorphism

This randomized, double-blind, placebo-controlled trial evaluates the efficacy of a zinc, selenium, and L-tyrosine supplement in preventing thyrotoxicosis among adults aged 18-85 with elevated TPOAb levels and the r25191G/A SEPP1 polymorphism. The study excludes those with thyroid disease, pregnant/breastfeeding women, and individuals allergic to the supplement. Key endpoints include changes in thyroid antibodies and hormones over a 6-month period. With an estimated sample size of 150 participants per group, accounting for a 20% dropout rate, the trial seeks to demonstrate the supplement's potential in reducing thyrotoxicosis risk through a genetically-informed approach.
