TNRF:Fc to Treat Eye Inflammation in Juvenile Rheumatoid Arthritis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00001862

Brief Summary:

This study will investigate the safety and effectiveness of the drug TNFR:Fc to treat uveitis (eye inflammation) in patients with juvenile rheumatoid arthritis. In other studies, TNFR:Fc significantly reduced joint pain and swelling in adult patients with rheumatoid arthritis, and the Food and Drug Administration has approved the drug for that use. Because medicines for arthritis often help patients with eye inflammation, this study will examine whether TNFR:Fc can help patients with uveitis.

Patients with uveitis who are not responding well to standard treatment, such as steroids, and patients who have side effects from other medicines used to treat their uveitis or have refused treatment because of possible side effects may be eligible for this study. Candidates will be screened with a medical history, physical examination, and eye examination. The eye exam includes a check of vision and eye pressure, examination of the back of the eye (retina), and front of the eye, including measurements of protein and inflammation. Candidates will also undergo fluorescein angiography-a procedure in which photographs are taken of the retina to see if there is any leakage in the eye's blood vessels. A blood test and joint evaluation will also be done.

Study participants will be given a shot of TNFR:Fc twice a week for up to 12 months and may continue other medicines they may be taking, such as prednisone or methotrexate. They will have follow-up examinations at week two and months one, two, three and four. Those who wish to continue treatment after the fourth month can receive the drug for another eight months and will have follow-up exams at months six, nine and 12, and one month after treatment ends. Each follow-up visit will include a repeat of the screening exams and an evaluation of side effects or discomfort from the medicine.

Condition or disease Intervention/treatment Phase
Juvenile Rheumatoid Arthritis Uveitis Drug: Enbrel Phase 2

Detailed Description:
Current treatment modalities for uveitis associated with Juvenile Rheumatoid Arthritis (JRA) including corticosteroids and other immunosuppressive agents are associated with significant side effects. These treatments are not effective for all children. A soluble tumor necrosis factor receptor (TNFR:Fc) named Etanercept, may inhibit the inflammatory response of uveitis. This randomized double-masked phase I/II clinical trial will provide limited safety and efficacy information regarding the use of Etanercept for the treatment of uveitis associated with JRA. Fifteen patients will be randomized with a 2 to 1 randomization plan (10 to receive Etanercept, 5 to receive placebo) and followed for 6 months. After the 6 month visit, all patients will receive open label Etanercept for an additional 6 months. Patients will be switched to open label Etanercept, or withdrawn from study therapy prior to 6 months, if they a) experience a greater than 10 letter or greater drop in visual acuity due to inflammation, for patients using the ETDRS chart (a 2 line drop due to inflammation, for patients using the B-VAT method) or b) develop a sight-threatening inflammatory ophthalmic or joint lesion requiring immediate increase in systemic anti-inflammatory therapy or a periocular injection of corticosteriods or c) at 4 months, have greater than 1 plus anterior chamber cell grade in either eye and are receiving topical corticosteroids on a schedule of TID or more frequently. Investigators will remain masked to original treatment assignment unless warranted by clinical care considerations. Primary safety outcomes include the occurrence of any severe adverse event at least possibly related to study therapy, including a two step increase in anterior chamber cells, or the occurrence of serious infection or sepsis. Primary ophthalmic outcomes include measures of anterior chamber cells and a change in topical or systemic anti-inflammatory medications used to treat uveitis. Primary ophthalmic and JRA outcome analysis will be performed at 6 months, and again at 12 months. Patients unmasked or switched to open label Etanercept prior to month 6 or withdrawing from the study drug prior to month 12 will be considered failures.
