HAT in Eye Complications of Behcet's Disease
This study will evaluate the safety and effectiveness of Zenapax in controlling recurrent eye inflammations associated with Behcet's disease.
Behcet's disease is usually treated with corticosteroids to suppress inflammation. Other medicines such as methotrexate, cyclophosphamide, or azathioprine may also be used. These drugs all can have serious side effects, including liver or kidney damage. Zenapax is a monoclonal antibody that binds to certain proteins (receptors) on white blood cells, preventing them from interacting with a chemical called interleukin-2. Blocking this interaction prevents inflammation.
This study will include 20 patients who had unacceptable side effects from other medicines used to treat their disease; did not benefit from standard treatment; and refused standard treatment because of possible side effects of the medicines.
All patients in the study will continue to take their current medicines at the start of the study. In addition, one group of patients will receive Zenapax and a second group will receive a placebo. The drug or placebo will be infused into the vein at the start of the study and every two weeks for the next six weeks, and then every four weeks for the rest of the study period (24 months). Each infusion lasts about 15 minutes. Patients will have eye examinations at the time of every treatment, and medicines will be added if needed to control eye disease. Drugs will be tapered after six months in patients whose eye disease is quiet, and readjusted as necessary. Neither the doctors nor the patients will know who is receiving placebo and who is receiving Zenapax until the study ends.
Patients will be given a physical examination, medical history, eye examination, fluorescein angiography (special photographs of the retina to evaluate the blood vessels in the eye), and blood tests.
Zenapax was previously studied in 10 patients with uveitis with positive results. The patients were able to reduce the other medicines they were taking with minimal side effects.
