About this study

Official title: Thyroid Hormone Replacement for Subclinical Hypothyroidism (TRUST) - Subanalysis on Subclinical Hypothyroidism and Depression

Mild thyroid failure is a common condition among older adults and has been associated with numerous adverse effects on health, such as cardiovascular disease, cognition disturbances and muscular problems. Mild thyroid failure has also been associated with an increased risk of developing depression. To date, only few studies have investigated the effect of thyroid hormone replacement on depression in patients with mild thyroid failure. This study therefore aims to assess whether thyroid hormone replacement in older adults with mild thyroid failure is associated with a decrease in the presence of depressive symptoms. This study forms a substudy of a large international study on thyroid hormone replacement in older adults with mild thyroid failure (the TRUST study).

Background

Subclinical hypothyroidism is a common condition among older adults, particularly above the age of 65 years, with a prevalence reaching 10 to 15% of the population. This condition has been associated with numerous adverse outcomes, such as cardiovascular disease, cognition disturbances and muscular problems. All of these potential outcomes will be assessed in the TRUST study. Subclinical hypothyroidism has also been associated with an increased risk of developing depression. It has been suggested that subclinical hypothyroidism may lower the threshold for the development of depression. The prevalence of depression among community-dwelling elderly ranges from 2 to 10%. Patients with depression have been shown to have a lower response to anti-depressive drugs when they have subclinical hypothyroidism. Only a few randomized studies in patients with subclinical hypothyroidism have studied the effect of thyroid hormone replacement on depression, with conflicting results: the studied populations were often small (maximal number of participants: 143), using different scales to measure the presence of depressive symptoms.

Objective

To investigate whether thyroid hormone replacement in older adults with subclinical hypothyroidism is associated with a decrease in the presence of depressive symptoms in a sub-study of the TRUST study.

Methods Use of the 15-item Geriatric Depression Scale (GDS-15) to measure depressive symptoms in all 450 patients included in the TRUST study in Switzerland and the Netherlands, the most validated test for depression screening, with validity to measure longitudinal changes. GDS-15 will be applied at baseline and after 1 year to compare changes in depression scores between placebo and thyroxin arms. Power calculation (ANCOVA method) with 225 participants per treatment group, assuming a standard deviation of 3 and a baseline to follow up correlation of 0.7, results in 99.9% power for detecting a mean difference of 1.0 points at a two-sided alpha-level of 0.05. Depending on recruitment for the main trial (ClinicalTrials.gov ID: NCT01660126) in respective countries, a lower number of participants may be included, retaining a very large power for this continuous outcome.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LevothyroxineDrug

    The intervention will start with Levothyroxine 50 µg daily (reduced to 25 µg in subjects <50Kg body weight or if known coronary heart disease - previous myocardial infarction or symptoms of angina pectoris) versus matching placebo; at 3 months if the serum TSH level is <0.4 mU/L dose will be reduced by 25 µg; TSH >=0.4 and <4.6 mU/L, no change to dose; TSH >=4.6mUL, additional 25 µg. The process will be repeated at 12 months then annually. Mock titration will be performed in the placebo group. The maximum possible dose of Levothyroxine that will be prescribed is 150μg (after 4 increments of 25μg at 3 months, 1, 2 and 3 years; from the starting dose of 50μg).

  • PlaceboDrug

    Control patients will obtain a placebo pill of the same characteristics as the intervention drug, and mock titration will be carried out identically to the intervention drug.

    Pharmaceutical composition of placebo (100 mg): Lactose monohydrate 66 mg, Maize starch 25 mg, Gelatin 5 mg, Croscarmellose sodium 3.5 mg, Magnesium stearate (vegetable source) 0.5 mg.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levothyroxine in people with Subclinical Hypothyroidism and Depression, run by Insel Gruppe AG, University Hospital Bern at 3 sites in 2 countries.

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 9 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 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Switzerland, Netherlands. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Change from baseline in 15-items Geriatric Depression Scale (time frame: At 1 Year). 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 NCT01853579, which also lists 1 linked publication.

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 Jun 2018.
