Brief Summary:
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 eyes 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

Detailed Description:
Pediatric uveitis represents 5-10 of all patients with uveitis Uveitis refers to intraocular inflammatory diseases The most common type of non-infectious pediatric uveitis associated with a systemic disease is JIA-associated chronic anterior uveitis Therapeutic considerations for pediatric uveitis are often very challenging Current therapeutic modalities include corticosteroids and other immunosuppressive agents These modalities are not always effective at controlling the disease In addition they can also be associated with a higher rate of ocular side effects To further add to this challenge pediatric uveitis has a higher rate of ocular complications even with the current therapies Consequently an effective treatment with a safer side effect profile is highly desirable Daclizumab is a humanized monoclonal antibody directed against the high affinity interleukin-2 IL-2 receptor CD25 or Tac subunit The IL-2 receptor system plays a central role in mediating immune responses Blocking this system impedes immune responses and can inhibit local inflammatory responses including uveitis Pilot studies using intravenous or subcutaneous daclizumab treatments suggest that daclizumab treatments at 2 mgkg every 2-4 weeks for quiescent uveitis may effectively replace the other immunosuppressive medications in a majority of cases
Because we have little experience using daclizumab for active uveitis in a pediatric population this feasibility study will enroll seven study participants that would normally be treated with systemic high-dose corticosteroids or other cytotoxic systemic immunosuppressive medications Since daclizumab for other indications can be tolerated with repeated dosing at 8-10 mgkg we will administer daclizumab to reach high serum levels with a pair of doses at 8 mgkg and 4 mgkg two weeks apart The primary objective of this study is to collect preliminary information on the utility of acute daclizumab therapy on active ocular inflammation in a pediatric population The primary outcome is resolution of active disease defined as a two step reduction in the anterior chamber cell scale from baseline Safety assessment will be made at 28 days and efficacy assessment at 8 weeks after the initial daclizumab injection Secondary outcomes will include fluorescein retinal vascular leakage cystoid macular edema vitreous haze and visual acuity In addition all adverse events will be collected regardless of possible relation to daclizumab Participants who do not meet the safety end point at day 28 will be permitted to continue IV daclizumab maintenance treatments beginning at Day 28 with 2 mgkg every 4 weeks An efficacy assessment will be made at 8 weeks and patients who show a 2 step reduction in their intraocular inflammation and has not met the safety end point will continue daclizumab treatment with 2mgkg every 4 weeks for a total of 52 weeks in the study At any time during the follow-up period if a participant loses greater than 3 lines of visual acuity from baseline study or meet the safety end point treatments will be discontinued
The primary objective of this feasibility study is to gain preliminary information regarding the safety and possible efficacy of daclizumab to treat active uveitis associated with JIA
The primary focus of this feasibility study is a short or acute response trial to relatively high-dose daclizumab infusions to observe if the anterior cell and flare associate with active JIA-associated uveitis can be promptly reduced In order to qualify for enrollment each participant must meet all of the inclusion criteria and not meet any of the exclusion criteria This study will enroll seven participants at the National Eye Institute NEI who currently have active JIA-associated active uveitis Enrollment is expected to take approximately three months The two induction treatments will be completed within 14 days with the primary safety evaluation at Day 14 and Day 28 and primary efficacy assessment at 12 weeks An induction regimen of intravenous IV daclizumab at 8 mgkg is given on Day 0 followed by another IV dose of 4 mgkg at Day 14 provided the safety endpoint has not been met
An efficacy assessment will be made at 12 weeks and patients who show a 2-step reduction in their intraocular inflammation and has not met the safety endpoint will continue with daclizumab therapy Meeting the safety failure criterion or having a serious adverse affect attributable to the daclizumab therapy will be cause for termination from further daclizumab study treatments Continuing follow-up and standard-of-care alternative treatments with a potentially reduced visit schedule will be provided through the duration of the trial if daclizumab treatments are suspended After the trial participants may seek other standard-of-care treatments from their own physician or ophthalmologist or they may be eligible to enroll in other research trials if these are available
Participants who show a 2-step reduction in their ocular inflammation or a decrease to inactivity without serious adverse events will have the option to receive extended treatments of 2 mgkg IV daclizumab treatments at 4-week intervals beginning day 28 for up to a total of 52 weeks in the study
