About this study
Official title: Protection From Iatrogenic Hypothyroidism Patients With MBL and Pediatric Patients With HL and Non-HL Needing Radiotherapy on Thyroid Site
To offer the possibility of a treatment that could achieve a meaningful reduction in the incidence of post-radiation therapy hypothyroidism. Thyroid dysfunction may develop from a few months to several years after patients have completed their radiation treatment. In children with chronic diseases, or given lengthy anti-neoplastic treatments, recurrent or persistent endocrine disorders may have a negative effect on growth and development into adulthood.
Read the detailed description
Patients will undergo basal thyroid ultrasound and FT3, FT4, TSH assay. Simulations with computed tomography, and computer assisted three-dimensional treatment planning with a dose volume histogram will be used to identify thyroid volumes and corresponding RT isodose distributions.
The enrolled patients will be randomly assigned (1:1) to TSH suppression group (experimental group) or non-TSH suppression group (control group). Random allocation will be managed centrally by Clinical epidemiology and Trial organization of the Fondazione IRCCS Istituto Nazionale dei Tumori. The randomization list will be generated by SAS software. Investigators and patients will not be masked to treatment allocation.
From 14 days beforehand and throughout their RT, patients in the experimental arm will receive L-thyroxine in the morning on an empty stomach (half an hour before breakfast), starting with 1-2 μg/kg, and adjusting the dose every 3 days to ensure TSH < 0.3 μIU/mL before RT beginning. The 0.3 μIU/mL threshold is just below normal range not causing hyperthyroidism, and is defined as "mild" TSH suppression. Based on hormone status, L-thyroxine doses will be gradually increased to patients' individual minimum TSH-suppressive dose before starting RT, maintained throughout the treatment, then rapidly tapered off (half dose the next day after RT, 25% the following day and stop).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LevothyroxineDrug
Also called Thyroid drugs
Levothyroxine is used to treat hypothyroidism (low thyroid function). This medicine is given when your thyroid does not produce enough of this hormone on its own.
| Study group | Role | What they receive |
|---|---|---|
| TSH suppression during irradiation | Experimental | From 14 days beforehand and throughout their RT, patients in the experimental arm will receive L-thyroxine in the morning, starting with 1-2 μg/kg, and adjusting the dose every 3 days to ensure TSH < 0.3 μIU/mL before RT beginning. The 0.3 μIU/mL threshold is just below normal range not causing hyperthyroidism, and is defined as "mild" TSH suppression. Based on hormone status, L-thyroxine doses will be gradually increased to patients' individual minimum TSH-suppressive dose before starting RT, maintained throughout the treatment, then rapidly tapered off and stopped. During radiation treatment course will be checked twice a week for serum FT3, FT4, TSH assays in order to maintain TSH < 0.3 μIU/mL, possibly without exceeding normal levels of FT3 and FT4. Once a week patients will also have a full visit and any other blood examination according to protocol in use and Institutional practice. Receives: Drug: Levothyroxine |
| Any TSH suppression during irradiation | No intervention | Patient in the standard arm will perform radiotherapy treatment without any TSH suppression. At the end of radiation they will do serum FT3, FT4, TSH assay and then, after one year from RT, thyroid ultrasound + serum FT3, FT4, TSH assay. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hypothyroidism-free survival
Hypothyroidism-free survival at 3 years after radiotherapy including part or the whole thyroid parenchyma on the intention-to-treat population will be the main end-point.
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Levothyroxine in people with Hypothyroidism; Irradiation, run by Fondazione IRCCS Istituto Nazionale dei Tumori, Milano at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 6 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Maura Massimino, MD (+0390223902593, maura.massimino@istitutotumori.mi.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hypothyroidism-free survival (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05316922, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2023.
