Filter by:This study will determine whether treatment with a combination of the drugs daclizumab and denileukin diftitox can eliminate the need for long-term daclizumab treatment in adult patients with uveitis. Denileukin diftitox kills white blood cells called lymphocytes that cause inflammation and may be the cause of uveitis. Patients 18 years of age and older with uveitis in one or both eyes who are on daclizumab therapy and have not had a disease flareup in 6 months may be eligible for this study. Candidates are screened with a medical history, physical examination, eye examination (including vision test, examination of the front of the eye, and pupil dilation for examination of the retina at the back of the eye), blood tests and a questionnaire about their vision and daily activities. After screening, participants undergo the following procedures: - Daclizumab/ denileukin diftitox treatment. Patients receive their regular dose of daclizumab intravenously (through a vein). The interval between doses is increased by 1 week after each dose. When the doses are 10 weeks apart, the daclizumab is stopped. Patients who experience a flare or uveitis are treated with intravenous denileukin diftitox and possibly local injections of steroids around the eye or increasing or adding other medicines as needed to control the uveitis. - Fluorescein angiography to look for blood vessel abnormalities in the eyes. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina (the back portion of the eye) are taken with a special camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible abnormalities. - Ultrasound and urine tests at enrollment and after 1 year to check kidneys, lymph nodes and pelvic area. - Blood tests at enrollment and every 3-6 months for laboratory and immunology tests and other research tests on blood cells to examine the immune response. - Follow-up visits approximately every 6 weeks for 2 years for repeat examinations to determine the response to treatment and drug side effects.
This research study is for patients that have been diagnosed with chronic uveitis, a disease that causes inflammation in the eye. Patients are currently being treated with Remicade, Humira, Methotrexate and or similar chemotherapy type drugs to control this inflammation. Despite these medications, patients still have inflammation in their eyes. Patients are being asked to add an additional drug, thalidomide.
This study examined the safety and potential efficacy of the monoclonal antibody efalizumab (Raptiva) for treating sight-threatening uveitis (eye inflammation). Efalizumab controls the activity of white blood cells called lymphocytes that cause inflammation. The drug is currently approved in the United States to treat patients with moderate to severe psoriasis. Participants 18 and older with sight-threatening intermediate or posterior uveitis of at least 3 months duration, causing persistent macular edema in one or both eyes, were eligible for this study. The uveitis required treatment with at least 20 milligrams per day of prednisone, or the equivalent, or a combination of two or more anti-inflammatory treatments such as prednisone, methotrexate, cyclophosphamide, cyclosporine, etc. Participants underwent the following tests and procedures: - Medical history and physical examination. - Weekly efalizumab treatment. - Weekly eye examination, including measurement of vision and pressure in the eyes, dilation of the eyes and examination of the front and back parts of the eye. - Weekly blood tests to measure the number and types of cells in the blood and to check for signs of inflammation and treatment side effects. At some visits, blood samples were collected to measure how much efalizumab remains in the blood and whether the body has developed an immune response to the medicine. - Blood draw at enrollment and at 2 and 4 months for research tests to examine how participants' immune response was operating. - Fluorescein angiography at enrollment and 1 and 3 months after enrollment, unless additional tests are needed, for medical management. This test checked for abnormalities of eye blood vessels. A yellow dye was injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina (the back portion of the eye) were taken with a special camera that flashes a blue light into the eye. The pictures show whether any dye has leaked from the vessels into the retina, indicating possible abnormalities. - Monthly pregnancy test for women who could become pregnant. Participants returned for treatment and clinic visits weekly for 16 weeks. After 16 weeks, participants whose macular edema had decreased and whose vision may have improved were offered to continue the injections.
This project is designed to test the hypothesis that inhibition of binding between tumor necrosis factor alpha (TNF-alpha) and its receptors using Remicade (infliximab, chimeric mouse/human IgG1K monoclonal antibody directed against human TNF-alpha, Centocor, Malvern,PA) is clinically useful for patients with uveitis that is refractory to other forms of systemic immunosuppressive therapy.
The primary objective was to demonstrate that two days of treatment with 0.5% prednisolone acetate eye-drops after cataract surgery are superior to vehicle in reducing the flare in the anterior chamber of the operated eye.
The purpose of this study is to investigate if interferon-alpha2a is superior to the standard treatment with cyclosporin A for the treatment of severe ocular manifestations of Behcet`s disease.
The purpose of this study is to compare the effectiveness of standardized systemic therapy versus fluocinolone acetonide implant therapy for the treatment of severe cases of non-infectious intermediate uveitis, posterior uveitis, or panuveitis.
This study will examine the safety and effectiveness of a monoclonal antibody called humanized anti-Tac (HAT, also called daclizumab) to treat children and adolescents with uveitis (chronic inflammatory eye disease) associated with juvenile idiopathic arthritis (JIA). Monoclonal antibodies are genetically engineered proteins made in large quantities and directed against a specific target in the body. The HAT antibody is designed to prevent a specific chemical interaction needed for immune cells to produce inflammation. Current treatments for uveitis include steroids and immune-suppressing drugs. These treatments do not always work or they may cause significant side effects. This study will determine whether daclizumab can improve uveitis in children and reduce the need for other medicines. Patients between 6 and 18 years of age with active non-infectious JIA-associated uveitis requiring treatment with anti-inflammatory medications as often as three times a day or more may be eligible for this study. Each candidate is screened with a medical history, physical examination, blood tests, eye examination, and the following specialized tests: - Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating the presence of inflammation. - Optical coherence tomography to measure retinal thickness. The eyes are examined through a machine that produces cross-sectional pictures of the retina. These measures are repeated during the study to determine changes, if any, in retinal thickening. - Stereoscopic color fundus photography to examine the back of the eye. The pupils are dilated with eye drops to examine and photograph the back of the eye. Upon entering the study, participants receive a 90-minute infusion of daclizumab through a catheter (plastic tube) placed in an arm vein. They return to the clinic after 14 days and again after 28 days for repeat eye examinations, blood tests, and daclizumab infusions. Four weeks after the third infusion, patients are examined for response to treatment. Those who have benefited from daclizumab may continue receiving monthly infusions of the drug for up to one year. A blood test and eye examination are done at the time of each infusion. Patients whose disease has remained active 12 weeks after the first infusion are taken off the study and treated with other medications.
This study will evaluate whether therapy that suppresses the immune system given to treat inflammatory diseases of the eye is associated with a greater risk of death and of cancer. Inflammatory diseases of the eye, including uveitis, scleritis, and mucous membrane pemphigoid, are major blinding diseases. For some patients, treatment with corticosteroids is not enough to control the diseases. Researchers expect to gain information about whether immunosuppressive therapy is suitable for patients and which substances should be avoided. Also, the study will evaluate the frequency of short-term complications with immunosuppressive therapy as well as benefits that the therapy can bring to treatment of eye diseases. The medical charts of patients up to age 65 (median age range of 21 to 65) who have had an inflammatory, noninfectious eye disease may be examined for this study. A database will be constructed through a chart review of patients seen in the uveitis clinic of the National Eye Institute since 1977 and three other sites. Patients who are considered exposed to immunosuppressive therapies will be compared with two groups: the general U.S. population and an internal group of patients with the same inflammatory eye diseases who did not receive immunosuppression. Data regarding about 10,000 to 15,000 patients will be collected. Patients will not be identified by the chart reviews. The incidence of cancer will be examined as well as the outcomes of immosuppressive therapy as measured by control of the eye disease, visual sharpness, changes in the use of corticosteroids, and rates of remission-when disease symptoms are lessened. Also examined will be medical charts of a control group of patients who did not receive immunosuppressive therapy for their uveitis. Data on cancer incidence would be more difficult to obtain, requiring personal contact with patients. In such situations, patients will be contacted by phone or mail, and those providing informed consent will be asked about their medical history, including previous occurrence of cancer and other conditions. For patients who have died, the researchers will attempt to communicate with the next of kin regarding this medical information.
The purpose of this study is to determine whether denufosol tetrasodium (INS37217) Intravitreal Injection is well tolerated and has the potential to treat uveitis associated macular edema.
