Study Type: Interventional

Official Title: Pilot Study of the Evaluation of Infliximab in the Treatment of Non-Infectious Scleritis

Brief Summary:

This small, preliminary study will examine whether multiple infusions of infliximab (Remicade® (Registered Trademark)) can control inflammation in patients with active scleritis. The sclera is the tough white outer coat enclosing the eyeball. Infliximab is a combination of part human and part mouse proteins that block a natural body protein called tumor necrosis factor (TNF). TNF appears to be involved in scleritis, and stopping its action may help reduce the inflammation in the disease. The drug has been approved by the Food and Drug Administration for treating Crohn's disease and rheumatoid arthritis.

Patients 18 years of age or older with active non-infectious scleritis may be eligible for this study. Participants will undergo the following tests and procedures:

  • Medical history and physical examination.
  • Eye examination, including a vision test and examination of the retina (back part of the eye) and of the sclera and its blood vessels.
  • Questionnaire about vision and daily activities.
  • Tuberculin skin test.
  • Pregnancy test: Women who can have children are tested for pregnancy at study weeks 0, 14, 30, 38, and 46.
  • Infliximab treatment: Infliximab is infused over a 2-hour period through a needle in a vein, usually in the arm. The patient's vital signs are checked before the patient begins each infusion starts and again before leaving the clinic. After the first two infusions, if the disease remains quiet, other scleritis medications will be attempted to be reduced to half the original dose over 8 to 12 weeks and possibly to nothing if the patient continues to do well. Patients receive a maximum of 9 infusions over a

    Detailed Summary: We propose to investigate the possible efficacy of multiple infliximab infusions to control the inflammation in participants presenting with active scleritis. This will be performed using an open-label pilot study. Subjects will receive 5mg/kg intravenous infusions of infliximab at 0, 2, 6 and 10 weeks. After these initial infusions, participants may contine to receive 5 mg/kg dose infusions or may receive 8 mg/kg dose infusions depending on the treamtent response. Treatment response is defined as a decrease in inflammation by at least 2 steps on the scale of grades 0-4 , or a decrease to 0 assessed at week 14. A combination of thse two dose infusions (5 mg/kg or 8 mg/kg) will be given for the remainder of the study according to set schedules. The primary outcome will be the ability to control active scleritis defined as at least a 2-step decrease in sleral inflammation,scleritis within 14 weeks of initiating infliximab therapy. Secondary outcomes will be the amount of reduction in concomitant immunosuppressive medication (measured using the grading scale in Section 4.5.2), changes in pain, redness (measured using a visual analogue scale), photophobia, changes in visual acuity (changes of 10 letters from baseline in best-corrected visual acuity will be considered clinically significant), the typical time between flares, and numbers of flares and times between flares while in the study.
