Combination T4/T3 vs T4 alone for autoimmune hypothyroid fatigue
Part of Hormones & metabolism, Immune system & allergy clinical trials.
This trial compares adding T3 (plus T4) versus taking only T4 to see if it improves severe ongoing tiredness in people with autoimmune hypothyroidism. You would stay on your thyroid medicine plan during the study and be monitored with blood tests and health checks.
Summary written for real people, not researchers, by Clin2.

- You’re 18 or older with primary hypothyroidism that is overt or mild/subclinical

This study aims to improve lab tests for people with hypothyroidism who take levothyroxine. It compares their test results to healthy volunteers to see if doctors can make more accurate diagnoses.
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 study is testing whether Armour Thyroid (a natural pig-derived thyroid hormone) works as well as synthetic T4 (levothyroxine) for people with hypothyroidism. If you are already on a stable dose of levothyroxine, you may be able to switch to Armour Thyroid and see how it compares.
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 study tests a mobile app designed to help adults with an underactive thyroid (hypothyroidism) take their thyroid medication more consistently. The goal is to see if better medication adherence improves tiredness, weight, and thyroid hormone levels.
This trial tests whether adding levothyroxine (a thyroid hormone) to a low-calorie diet helps people with obesity lose more weight. It is for adults aged 25-60 with a BMI of 30-39.9 who have either mild underactive thyroid or normal thyroid but higher thyroid hormone levels in the normal range.
