Inclusion Criteria

• Subjects with a documented history of non-infectious anterior, anterior and intermediate, or pan-uveitis

• Uncontrolled uveitis, as evidenced by Grade 2+ or higher anterior chamber cells, in at least one eye for = 2 weeks prior to randomization

• In subjects whose diagnosis is not exclusively anterior uveitis, the predominant manifestation of their condition at the time of enrollment must be anterior segment inflammation

• Current uveitis therapy must conform to one of the following:
• Prednisone monotherapy at a dose of = 10 mg/day (or equivalent) for = 2 weeks prior to randomization
• Have received = 2 injections of corticosteroid (intravitreal or periocular) for control of disease within the past 8 months, but not within 2 weeks of randomization; subjects may also be receiving systemic corticosteroid therapy
• Receiving monotherapy with azathioprine, mycophenolate mofetil, mycophenolic acid or methotrexate for at least 2 weeks prior to randomization
• Receiving prednisone in addition to one immunomodulatory agent from among cyclosporine, tacrolimus, azathioprine, mycophenolate mofetil, mycophenolic acid and methotrexate for at least 2 weeks prior to randomization
• Subjects for whom corticosteroid therapy (systemic or local) is medically inappropriate or who refuse corticosteroid therapy

• Considered by the Investigator to require immunomodulatory therapy

• Subject does not plan to undergo elective ocular surgery (e.g., cataract extraction) during the study

• A minimum ability to count fingers at a distance of 30 cm (1 foot) using the study eye

All other female subjects (including those with tubal ligations) will be considered to be of childbearing potential

• Subjects must weigh at least 38 kg (84 lbs) and no more than 110 kg (242 lbs) (Note: this restriction is imposed to allow for the masking of treatment assignments.)
