The Safety and Efficacy of a Tumor Necrosis Factor Receptor Fusion Protein on Uveitis Associated With Juvenile Rheumatoid Arthritis
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Patients will be switched to open label Etanercept, or withdrawn from study therapy prior to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.
