Supplement to prevent thyroid hormone overload in at-risk people
Part of Hormones & metabolism clinical trials.
This trial tests whether a supplement containing zinc, selenium, and L-tyrosine can help prevent a condition called thyrotoxicosis (too much thyroid hormone) in people with a specific gene change. It is for people who have high levels of thyroid antibodies and a certain genetic marker.
Summary written for real people, not researchers, by Clin2.

- You must have a specific gene change called r25191G/A in the SEPP1 gene.
- Your blood test for TPO antibodies (TPOAb) must be above 300 IU/mL.
- You must be between 18 and 85 years old.
- You cannot be pregnant or breastfeeding.

This trial tests if adding a second thyroid hormone (T3) to standard levothyroxine (T4) can better relieve persistent hypothyroidism symptoms like fatigue or brain fog. You may qualify if you still have symptoms despite being on a stable dose of levothyroxine.
This trial tests a new porcine (pig) thyroid hormone replacement tablet for people with primary hypothyroidism (underactive thyroid). It aims to see if this treatment is safe and effective compared to current levothyroxine therapy.
This study tests a new approach for people with hypothyroidism who are already taking levothyroxine. You may be able to join if you are on a certain dose and do not have other health conditions that could affect the results.
This trial is for people who may have a problem with how their body responds to thyroid hormone. It aims to better understand, diagnose, and monitor these conditions to improve care.
This trial tests a new drug called SCTT11 in healthy people and in those with thyroid eye disease (TED) to see if it is safe and helpful. It may be an option if you have moderate-to-severe TED that affects your daily life.
This trial tests whether taking myo-inositol and selenium supplements can help reduce the risk of thyroid cancer in people with thyroid nodules that are considered 'indeterminate' (TIR3a). The goal is to see if these supplements can prevent the nodules from becoming cancerous.
