Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 1. Patients with Graves' disease, with or without GO. The presence of GO will be established in any patient who had at least one of the following eye features: a) exophthalmometry ≥17 mm in women and ≥19 mm in men, based on measurements conducted for the normal population; b) eyelid aperture ≥9 mm; c) clinical activity score ≥1/7; iv) presence of diplopia; v) presence of corneal alterations; vi) presence of GO-related alterations of the fundi; and vii) reduction in visual acuity that could be attributed to GO. 2. Patients with autoimmune thyroiditis 3. healthy subjects

Who may be able to join

  • for Graves' disease: a history of hyperthyroidism, associated with previous or present detectable serum autoantibodies against the TSH-R;
  • for autoimmune thyroiditis: the presence of at least two of the following: a) primary hypothyroidism; b) detectable serum autoantibodies against thyroglobulin or thyroperoxidase ; c) a hypoechoic pattern of the thyroid by ultrasound examination.
  • for healthy subjects: absence of any clinical, biochemical or instrumental evidence of thyroid diseases.
  • For all subjects: Informed consent

Who cannot join

  • 1) lack of informed consent

About this study

Official title: Serum Antibodies Against the Insulin-like Growth Factor-1 Receptor (IGF-1R) in Graves' Disease and Graves' Orbitopathy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of serum IGF-1R-Abs above the upper normal levels

    Percent prevalence of serum IGF-1R-Abs above the upper normal levels in patients with GO, compared with healthy subjects, patients with Graves' disease without a clinically relevant GO, and patients with autoimmune thyroiditis.

    Measured: Baseline

Secondary outcomes (5)
  1. Serum concentrations of IGF-1R-Abs

    Comparison of the serum concentrations of IGF-1R-Abs in patients with GO, compared with healthy subjects, patients with Graves' disease without GO, and patients with autoimmune thyroiditis;

    Measured: Baseline

  2. Relationship between serum IGF-1R-Abs and the activity of GO

    Relationship between serum IGF-1R-Abs (both levels and prevalence), with the the activity GO, namely the clinical activity score, including 7 items (spontaneous orbital pain, gaze provoked pain, palpebral redness, palpebral oedema, conjuctival redness, caruncle edema, chemosis) resulting in a score from 1 to 7

    Measured: Baseline

  3. Relationship between serum IGF-1R-Abs and anti-TSH receptor autoantibodies

    The relationship between serum IGF-1R-Abs (both levels and prevalence) and anti-thyrotropic hormone-receptor serum autoantibodies

    Measured: Baseline

  4. Relationship between serum IGF-1R-Abs and anti-thyroperoxidase autoantibodies

    The relationship between serum IGF-1R-Abs (both levels and prevalence) and anti-thyroperoxidase serum autoantibodies

    Measured: Baseline

  5. Relationship between serum IGF-1R-Abs and anti-thyroglobulin autoantibodies

    The relationship between serum IGF-1R-Abs (both levels and prevalence) and anti-thyroglobulin serum autoantibodies

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Graves Ophthalmopathy and Graves Disease, run by University of Pisa 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 4 inclusion and 1 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 30 Jul 2018. 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.

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?

Frequency of serum IGF-1R-Abs above the upper normal levels (time frame: Baseline). 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 30 Jul 2018.
