Leflunomide suppresses immune system activity and has been shown to control autoimmune diseases, such as arthritis (joint inflammation), in animals. It has also improved symptoms in patients with rheumatoid arthritis, and the Food and Drug Administration has approved it for treating patients with this disease. Eye and joint inflammation may have similar causes, and medicines for arthritis often help patients with eye inflammation. This study will examine whether Leflunomide can help patients with uveitis.\n\nPatients with uveitis who are not responding well to steroid treatment and patients who have side effects from other medicines used to treat uveitis (such as cyclosporine, cyclophosphamide, methotrexate or azathioprine) or have refused treatment because of possible side effects of these medicines may be eligible for this study. Candidates will be screened with a medical history, physical examination, blood test and eye examination. The eye exam includes a check of vision and eye pressure, examination of the back of the eye (retina) with an ophthalmoscope and the front of the eye with a microscope. They will also undergo a procedure called fluorescein angiography to look at the blood vessels of the eye. A dye called sodium fluorescein is injected into the bloodstream through a vein. After the dye reaches the blood vessels of the eye, photographs are taken of the retina.\n\nStudy participants will be divided into two groups. One group will take 100 milligrams of Leflunomide once a day for 3 days and then 20 milligrams once a day for 6 months. The other group will take a placebo-a pill that looks like the Leflunomide pill but does not contain the medicine. All patients in both groups will also take prednisone. Patients will have follow-up examinations at weeks 1, 4, 8, 12, 16, and 24 (6 months) of the study. Each follow-up visit will include a repeat of the screening exams and an evaluation of side effects or discomfort from the medicine. Those who do well and want to continue their assigned treatment after 6 months can continue that treatment for another 6 months and will have follow-up exams at months 9 and 12.", "DetailedDescription"=>"Although corticosteroids remain the mainstay of therapy for intraocular inflammation, many patients are intolerant or resistant to corticosteroid therapy. In these patients, other immunosuppressive agents have been employed to control potentially sight-threatening uveitis. Nevertheless, ideal therapy for these patients remains elusive, and there is a need for new immunosuppressive agents with varying modes of action and side effect profiles. Leflunomide, an isoxazole derivative, has profound immunosuppressive activity. Leflunomide inhibits autoimmune disease in animal models and has been used to treat patients with rheumatoid arthritis (RA). We propose a randomized masked pilot trial of leflunomide versus placebo for the treatment of uveitis. Sixteen patients 16 years of age or older with active intermediate, posterior, or panuveitis will be randomly assigned to receive prednisone and leflunomide or prednisone and placebo. Patients will then have the prednisone tapered according to a standardized schedule. The primary purpose of the study is to investigate the safety and efficacy of leflunomide versus placebo. The primary safety endpoint is the frequency of any of the following: abdominal pain, diarrhea, skin rash, hypertension, and alopecia. In addition, weight loss distributions and change in liver function tests will be described. The primary efficacy endpoint is any one or more of the following (1) a decrease of 10 or more letters in visual acuity from the baseline score for any reason, or (2) inability to taper prednisone to 10 mg qd by week 16 post randomization, or (3) inability to maintain the prednisone taper through Month 6 or Month 12, or (4) the addition of systemic therapy to treat ocular inflammatory disease. Secondary outcomes will include change in vitreous haze and presence or absence of cystoid macular edema."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"INCLUSION CRITERIA:\n\nDiagnosis of current intermediate or posterior uveitis, or panuveitis.\n\nCurrent evidence of active intraocular inflammation based on the presence of vitreous haze, active retinal lesions, retinal vasculitis, or cystoid macular edema.\n\n16 years of age or older.\n\nVisual acuity of 73 letters or fewer (Snellen equivalent: 20/40 or worse) in at least one eye.\n\nThe ability to understand and sign an informed consent form which must be obtained prior to randomization.\n\nThe diagnosis of intermediate uveitis requires the presence of vitritis and either peripheral retinal vascular disease, cellular debris in the inferior vitreous (vitreous snowballs), exudate on the pars plana, or peripheral retinal infiltrates. The diagnosis of posterior uveitis requires the presence of infiltrative retinal lesions involving the posterior pole of the eye, usually with vitritis and often times with cystoid macular edema. The amount of cystoid macular edema will be graded by a standard protocol using Fluorescein Angiogram. The diagnosis of pan-uveitis requires the finding of active anterior segment inflammation, vitritis, and infiltrative retinal lesions.\n\nEXCLUSION CRITERIA:\n\nOcular or systemic disease requiring greater than 1 mg/kg/day of prednisone or greater than 80 mg qd if patients weigh more than 80 kg, or requiring other systemic immunosuppressants.\n\nPeriocular injections of corticosteroids within the previous 4 weeks.\n\nIntolerance or contraindications to corticosteroids.\n\nFemale who is pregnant or lactating.\n\nPatient refuses to use contraception during the study and 24 months after termination of active study therapy or undergo a cholestyramine washout regimen or an activated charcoal regimen under the care of a physician following termination of study therapy, if child-bearing or fathering potential exists.\n\nPatients with Behcet's disease.\n\nUse of Latanoprost within 2 weeks prior to enrollment, or current or likely need for Latanoprost during the course of the study.\n\nHypersensitivity to fluorescein dye.\n\nContraindications to use of steroids at dose and schedule.\n\nSGOT (AST) or SGPT(ALT) greater than or equal to 2 times the upper limit of normal.\n\nAllergic or hypersensitivity to leflunomide or any excipients."}, "IdentificationModule"=>{"NCTId"=>"NCT00001863", "BriefTitle"=>"Leflunomide to Treat Uveitis", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Institutes of Health Clinical Center (CC)"}, "OfficialTitle"=>"Pilot Study of Leflunomide for the Treatment of Uveitis", "OrgStudyIdInfo"=>{"OrgStudyId"=>"990059"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"99-EI-0059"}]}}, "ArmsInterventionsModule"=>{"InterventionList"=>{"Intervention"=>[{"InterventionName"=>"Leflunomide", "InterventionType"=>"Drug"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"20892", "LocationCity"=>"Bethesda", "LocationState"=>"Maryland", "LocationCountry"=>"United States", "LocationFacility"=>"National Eye Institute (NEI)"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Eye Institute (NEI)", "LeadSponsorClass"=>"NIH"}}}}}}
