About this study

Official title: An Observational, Retrospective, Single-center, Clinical Study to Evaluate the Efficacy of Sirolimus (Rapamycin) in Patients With Graves' Disease and Moderate-to-severe and Active Graves' Orbitopathy (GO)

Graves' Orbitopathy (GO) is a disabling and disfiguring condition associated with Graves' Disease, due to autoimmunity against antigens expressed by the thyroid and orbital tissues, and resulting in orbital fibroblast proliferation and release of glycosaminoglycans. The current treatments available, especially glucocorticoids, are not effective in all patients. Two cases of patients with GO treated with Sirolimus have been reported with an excellent response to the drug.

The rationale for the use of Sirolimus lies in its mechanisms of action. Sirolimus is able to inhibit T-cell activation as well as fibroblast proliferation. In addition, acts indirectly on the Insulin-Like Growth Factor-1 (IGF-1) pathway, and recent clinical trials have shown that a monoclonal antibody against the IGF-1 receptor (Teprotumumab) is effective in patients with GO. Thus, Sirolimus could be used in GO as monotherapy in patients with GO.

The aim of the present drug vs standard treatment, observational study is to evaluate the efficacy of Sirolimus as a second-line treatment in patients with moderately severe, active GO.

What is being measured

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

  1. GO overall response

    Percentage of subjects with at least two of the following compared to baseline: a) Improvement in clinical activity score (CAS) by at least 1 point ; b) Improvement in exophthalmos by at least 2 mm; c) Improvement in lid aperture by at least 2 mm; d) Improvement in eye muscle ductions ≥8 degrees; e) Improvement of visual acuity by at least 0.2/1, without worsening of any of these parameters in the contralateral eye if applicable.

    Measured: 24 weeks

Secondary outcomes (6)
  1. Change in exophthalmos

    Percentage of subjects with a reduction greater than or equal to 2 mm compared with the baseline evaluation in the study eye, without worsening in the contralateral eye

    Measured: 24 weeks

  2. Change in the clinical activity score (CAS)

    Percentage of subjects with a reduction of CAS by at least two points in the study eye, without worsening in the contralateral eye

    Measured: 24 weeks

  3. Change in quality of life

    Comparison of the quality of life scores between the two groups, determined with a questionnaire specific for GO (GO-QoL)

    Measured: 24 weeks

  4. Change in eye ductions

    Percentage of subjects with an increase in eye ductions at least 8 degrees

    Measured: 24 weeks

  5. Change in eyelid aperture

    Percentage of subjects with a reduction greater than or equal to 2 mm

    Measured: 24 weeks

  6. Change in diplopia

    Percentage with an improvement in diplopia

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Graves Ophthalmopathy, 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 5 inclusion and 3 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 25 Apr 2022. 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?

GO overall response (time frame: 24 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 25 Apr 2022.
