Primary Outcome Measures:
  • Clinical response to treatment, alteration in immunoglobulin levels [ Time Frame: One year post infusion ]
  • To assess the safety and tolerability of Rituximab in Graves' dysthyroid disease up to 24 weeks. Adverse and serious adverse events during the study period, reasonably or probably related to Rituximab, will be assessed at each study visit up to 12 month [ Time Frame: One year ]
  • Efficacy: [ Time Frame: One year after treatment ]
  • A significant (25%) reduction in progression of Thyroid Associated Ophthalmopathy or disease activity as measured by the thyroid associated ophthalmopathy scale (University of British Columbia Thyroid Orbitopathy Inflammatory Score) up to 24 weeks. [ Time Frame: One year ]

Secondary Outcome Measures:
  • To evaluate for a reduction in disease activity as measured by: [ Time Frame: One year ]
  • Reduction (25%) of elevated antibody levels- serum thyroid stimulating immunoglobulin (TSI), antithyroidperoxidase antibody (TPO) or antithyroglobulin levels at 24 weeks. [ Time Frame: One year ]
  • MRI of the orbit with coronal and axial views to evaluate evidence of optic nerve crowding, muscle size reduction or decreased proptosis during treatment and follow up interval at 24 weeks. [ Time Frame: Six months ]

Detailed Description:
Graves' Dysthyroid ophthalmopathy is an autoimmune disease characterized by inflammatory changes of the periocular and orbital region often in association with an underlying thyroid abnormality. These changes can be extremely debilitating and may lead to visual loss. Attempts at limiting or reversing the phenotypic expression of Graves' ophthalmopathy through aggressive orbital decompression surgery or targeting the inflammatory disease, using high dose systemic corticosteroids and/or orbital radiotherapy, have been limited to date by treatment ineffectiveness and co-morbidities. Selective B-cell depletion therapy offers a potential treatment alternative. This study is designed to treat patients with Graves' disease with Rituximab in an attempt to prevent or reverse the physically deforming and debilitating consequences of this disease.
