Novel Approaches to the Treatment of Hypothyroidism
United States90 participantsStarted 2024-12-10
Plain-language summary
Hypothyroidism is a common condition, more frequent in females, associated with excess of cardiovascular risk and poor quality of life not completely abrogated by treatment with levothyroxine.
There is an unmet need to define a safe, effective, and feasible regimen to be applied in large trials aimed at assessing levothyroxine/liothyronine combination therapy in patients living with hypothyroidism.
To address this knowledge gap we propose a randomized, three-arm, double-blind, controlled, escalating dose parallel pilot study whose results will lay the foundation of large multicenter trial(s) able to demonstrate the effectiveness (or lack thereof) of levothyroxine/liothyronine combination therapy.

Inclusion Criteria:
History of hypothyroidism Treatment with levothyroxine Levothyroxine dose \>1.2 mcg/kg
Exclusion Criteria:
Body weight \<50 or \>100 Kg.
Indication for TSH suppression (high risk follicular-derived thyroid cancer).
Secondary (pituitary) hypothyroidism (ICD-10 E23.0); Pregnancy; breastfeeding; uncontrolled diabetes (HbA1c \>8.5% at screening); use of oral Semaglutide (Rybelsus); Uncontrolled Hypertension (BP \> 140/90 at screening); current use of T3-containing therapies (Liothyronine, desiccated thyroid extracts).
Patients receiving lipid-lowering therapies must maintain the same dose throughout the participation in the study. Changes in lipid lowering therapy/dose will result in termination from the study.
Patients receiving anti-acid (H2 blockers, proton pump inhibitors) therapies must maintain the same dose throughout the participation in the study. Changes in anti-acid therapy/dose will result in termination from the study. Use of other medications known to interfere with the absorption of thyroid hormone, or affecting the thyroid hormone axis (Burch 2019) will be considered exclusion criteria.
Bariatric surgery, initiation of GLP-1 agonist therapy (irrespective of the indication), enrollment in structured weight loss programs will result in dismissal from the study.
Current pregnancy, pregnancy planned within the next 6 months, and lack of contraception in women of reproductive age will be exclusionary. We will verify that the participant is …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
