Primary Outcome Measures:
  • • European Group on Graves' Orbitopathy (EUGOGO) Clinical Activity Score [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Clinical Activity Score is a validated index of Graves' orbitopathy 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 (CAS) is thus 7.


Secondary Outcome Measures:
  • • Health related quality of life questionnaires (GO-QoL) [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • • Safety and tolerability as assessed by adverse events, vital signs [ Time Frame: 6 months. ] [ Designated as safety issue: Yes ]
  • Relapse [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 14
Study Start Date: October 2012
Estimated Study Completion Date: October 2013
Estimated Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Doxycycline
Tablets Doxycycline 50 mg PO per day for three months
 Drug: Doxycycline
Tab. Doxycycline 50 mg PO per day for 3 months
Other Names:
  • Dolotard
  • Tibirox
  • Biomycin

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.
