The purpose of this study is to investigate the safety and tolerability of otelixizumab in patients with Graves' ophthalmopathy (thyroid eye disease). There is currently no alternative therapy available for this condition other than treatment with steroids, or radiotherapy and surgery. The study also includes a comparison of the current steroid treatment, methylprednisolone, with the proposed new otelixizumab treatment.
This is a study of otelixizumab, a monoclonal antibody (MAb) directed against the human lymphocyte antigen CD3 (a protein found on a certain type of white blood cell). This will be an open-label, comparator-controlled, two part study to evaluate the safety and tolerability of otelixizumab in patients with Graves' ophthalmopathy (GO). It will also look to see if otelixizumab affects GO and how it works compared to methylprednisolone (the standard treatment for active GO).
In Part A, between one and four groups of 5 patients will receive doses of otelixizumab administered over 8 days. The first dose level will provide a cumulative 3.1mg dose, this dose has been safely administered in previous studies. Safety and clinical response data will be reviewed after 8 weeks, if no clinical response is seen and there are no safety concerns, the dose of otelixizumab will be increased and a new group of subjects will enter Part A. In subsequent groups cumulative doses of 4.6, 7.1 and 10.1mg may be investigated. However if a clinical response is seen at the lowest dose the study will move directly to Part B.
In Part B, patients will receive either otelixizumab at the dose set from Part A, over 8 days (5 patients) or methylprednisolone weekly for 12 weeks (5 patients). All dosing will be by intravenous infusion. All participants will undergo long term safety evaluation for 48 months.
Key assessments include vital signs, 12-lead ECG, liver function tests, thyroid function, viral monitoring, monitoring of cortisol and ACTH levels, laboratory safety tests and adverse event (side effect) data. Assessment of GO severity will be evaluated using recommended assessments including clinical activity assessments and quality of life questionnaires. Measurements of exploratory biomarkers (proteins found naturally in the blood) are also included in this study.

An autoimmune disorder of the EYE, occurring in patients with Graves disease. Subtypes include congestive (inflammation of the orbital connective tissue), myopathic (swelling and dysfunction of the extraocular muscles), and mixed congestive-myopathic ophthalmopathy.
A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
A water-soluble ester of METHYLPREDNISOLONE used for cardiac, allergic, and hypoxic emergencies.
A PREDNISOLONE derivative with similar anti-inflammatory action.
Immune-mediated inflammation of the PITUITARY GLAND often associated with other autoimmune diseases (e.g., HASHIMOTO DISEASE; GRAVES DISEASE; and ADDISON DISEASE).
