Clinical Trial Summary

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).


Clinical Trial 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. ;
