About this study

The purpose of this study is to examine the effects of Azithromycin (a macrolide class antibiotic), given three times weekly, for patients with active moderate-severe, non sight-threatening, Graves Orbitopathy.

Indices for follow-up will include:

  • Clinical activity score
  • Anti-TSH receptor antibody levels
  • Thickening of extraocular muscles per ultrasound
  • Quality of life score for Graves Orbitopathy patients
Read the detailed description

Graves Orbitopathy (GO) is an autoimmune inflammatory disorder causing visual morbidity, cosmetic morbidity and interference with quality of life. The disease has an inflammatory stage and a non-inflammatory, fibrotic stage.

Treatment of inflammatory stage moderate-severe GO includes steroids, as recommended by the EUGOGO consortium. However, the length of treatment needed and the risk of steroid side-effects may lead to multiple undesired treatment induced morbidity.

Antibiotics of the macrolide group posses known immune-modulatory effects that are separate from their antibacterial mode of action. This mode of action has lead to the routine use of macrolide antibiotics for delaying graft rejection following lung transplants.

We propose to test the effect of this class of antibiotics for non-sight threatening, moderate-severe, inflammatory GO.

What is being measured

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

  1. Change in clinical activity score between baseline and after three months

    Change in the clinical activity score between baseline and after 3 months

    (Clinical Activity Score is a validated index of Graves Ophthalmopathy that assigns one point to the presence of: 1.spontaneous retrobulbar pain, 2. pain on up/downgaze, 3. redness of eyelids, 4. redness of conjunctiva, 5. swelling of eyelids, 6. inflammation of caruncle/plica, 7. chemosis). The maximal clinical activity score is thus 7.

    Measured: Three months

Secondary outcomes (2)
  1. Measurement of extraocular muscle thickening

    Ultrasonic measurement of extraocular muscle thickening

    Measured: 3 months

  2. ANTI TSH Receptor antibody levels

    Serum measurements of ANTI TSH Receptor antibody levels

    Measured: 0, 3 and 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Azithromycin in people with Graves Ophthalmopathy, run by Rabin Medical Center.

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 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: withdrawn, as of the sponsor's last update on 27 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 was withdrawn before enrolling participants, so there are no results.

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 in clinical activity score between baseline and after three months (time frame: Three months). 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 27 Apr 2017.
