About this study

Official title: Efficacy of Subantimicrobial Dose Doxycycline for Moderate to Severe and Active Graves' Orbitopathy: a Prospective, Uncontrolled Pilot Study

The aim of this study is to evaluate the effects of subantimicrobial dose doxycycline (50 mg/d), administered for 12 wk, for patients with active moderate-severe Graves' Orbitopathy (GO).

Read the detailed description

Graves'orbitopathy is an autoimmune disease characterised by an inflammatory phase followed by fibrosis. Surgery to correct eyelid swelling, proptosis, and diplopia is effective, but can not be done until the inflammatory phase has passed. To arrest the inflammatory phase, several types of immunosuppressive treatments have been investigated. Corticosteroids are the first-choice immunosuppressive treatment, but they often cause severe side-effects.

Subantimicrobial dose doxycycline posses known anti-inflammatory effects that are separate from their antibacterial mode of action. This mode of action has lead to the routine use of subantimicrobial dose doxycycline for rosacea, periodontitis and multiple sclerosis.

We propose to test the effect of subantimicrobial dose doxycycline 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. • Treatment response

    As definition of treatment response, we used the major and minor criteria . Three major criteria were: improvement in diplopia grade (disappearance or change in grade); improvement of ≥8 degrees in any direction of eye movements; reduction of three points or more in CAS. Four minor criteria were: reduction of 2 mm or more in eyelid aperture; reduction of 2 mm or more in proptosis; improvement in grade of soft tissue swelling; decrease in CAS by at least two points. A successful response was defined as an improvement in one or more major criteria or in two minor criteria, in absence of deterioration of any criterion in that observed eye. Deterioration was defined as occurrence of DON, and/or worsening of soft tissue swelling, and/or worsening of diplopia, and/or an increase of ≥2 mm in lid aperture, and/or an increase of ≥2 mm in proptosis, and/or a decrease of ≥8 degrees in duction. No success was defined if there was no change or the changes did not reach the success criteria.

    Measured: 24 weeks

Secondary outcomes (2)
  1. Safety and tolerability as assessed by adverse events, vital signs

    Measured: 24 weeks

  2. Graves' orbitopathy-Specific Quality of Life (GO-QoL)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Doxycycline in people with Graves Ophthalmopathy and Graves Disease, run by Sun Yat-sen University at 1 site in China.

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 6 inclusion and 10 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 10 Dec 2013. 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 China. 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.

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 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?

• Treatment 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?

On the ClinicalTrials.gov record for NCT01727973, 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 10 Dec 2013.
