Method of Endogenous TSH Stimulation in the Follow-up of Differentiated Thyroid Cancer
A study testing L-thyroxin in people with Thyroid Cancer, run by University of Tartu at 2 sites in Estonia.
Trial summary
The treatment of differentiated thyroid cancer (DCT) includes surgery followed by radioiodine treatment. In the follow-up of patients it is necessary to induce TSH elevation to test for cancer recurrence. One of the options is to stop L-thyroxin replacement for several weeks. Read more about this study

About this study
The treatment of differentiated thyroid cancer (DCT) includes surgery followed by radioiodine treatment. In the follow-up of patients it is necessary to induce TSH elevation to test for cancer recurrence. One of the options is to stop L-thyroxin replacement for several weeks. Current pilot study aims to induce the necessary TSH elevation by decreasing the L-thyroxin dose. The main hypothesis is that necessary TSH stimulation will be achieved during 4-6 weeks in majority of patients.
Read the detailed description
The treatment of differentiated thyroid cancer (DCT) includes surgery followed by radioiodine treatment. In the follow-up of patients it is necessary to induce TSH elevation for the measurement of thyreoglobulin and/or total body scanning. There are two principal methods to obtain TSH elevation: 1) injection of recombinant human TSH , and 2) to stop L-thyroxin replacement for several (3-4) weeks. As use of recombinant TSH is rather expensive, this method is not feasible in many countries. The problem with stopping L-thyroxin is development of severe hypothyroidism for several weeks with concomitant symptoms and signs.
Current pilot study aims to induce the necessary TSH elevation by decreasing the L-thyroxin dose. The main hypothesis is that necessary TSH stimulation will be achieved during 4-6 weeks in majority of patients with fixed dose of L-thyroxin. Concomitantly, blood tests and symptoms and signs of hypothyroidism will be obtained to get information about possible deviations during treatment with low dose of thyroxin.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
L-thyroxinDrug
Low dose of L-thyroxin (50 microg/day) will be used during 4 weeks. If TSH is < 30 after 4 weeks the study continues up to 6 weeks.
| Study group | Role | What they receive |
|---|---|---|
| L-thyroxin | Experimental | this is one arm study Receives: Drug: L-thyroxin |
What is being measured
The primary outcome is the main question the study is designed to answer.
TSH level at the end of study
The percentage of patients obtaining TSH level at least 30 imU/L at the end of study period.
Blood tests will be obtained after 4 weeks. If TSH > 30 the patient has completed the study. If TSH < 30 patient will continue for 1 week and blood tests will be obtained after week 5. If TSH > 30 the patient has completed the study. If TSH < 30 patient will be monitored during 1 week and blood tests will be obtained after 6 weeks.
Measured: 4-6 weeks
Secondary outcomes (1)
change in Billewitz index during the study
Billewitz index measures the severity of hypothyroidism symptoms. Billewitz index will be recorded after 4 weeks and after 5 and 6 weeks if patient continues after 4 or 5 weeks (see primary endpoint for details).
Measured: 4-6 weeks

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 3 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: finished, as of the sponsor's last update on 14 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Estonia. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
TSH level at the end of study (time frame: 4-6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Mar 2014.
