Lucentis for Inflammatory Macular Edema Trial
Uveitis is an inflammation (swelling and irritation) inside the eye, affecting the uvea. The uvea is the layer of the eye between the sclera and the retina and provides most of the blood supply to the retina.
Uveitis is an important cause of visual loss. There are 30,000 new cases of legal blindness each year due to uveitis in the U.S. Sight-threatening complications associated with uveitis include macular edema, which may persist even when inflammation is controlled. The only current treatment for cystoid macular edema (CME) in uveitis patients is oral or regional steroid injections. For patients who don't respond to steroids or who are unable to tolerate steroid therapy, there are no other medical treatments.
The aim of this study is to determine if ranibizumab, an FDA-approved treatment for neovascular age-related macular degeneration, is an effective treatment for those patients with uveitis-induced CME who are unable to be treated with or non-responsive to steroids.
Uveitis, an inflammation that affects the uvea (iris, ciliary body and choroid), is an important cause of visual loss. There are 30,000 new cases of legal blindness each year due to uveitis in the U.S. Sight-threatening complications associated with uveitis include macular edema, which may persist even when inflammation is controlled. The only current treatment for cystoid macular edema (CME) in uveitis patients is oral or regional steroid injections. For patients who don't respond to steroids or who are unable to tolerate steroid therapy, there are no other medical treatments.
The aim of the proposed research is to determine if ranibizumab is an effective treatment for those patients with uveitis-induced CME who are unable to be treated with or non-responsive to steroids. Ranibizumab is a recombinant, humanized monoclonal antibody antigen-binding fragment (Fab) that neutralizes all active forms of vascular endothelial growth factor (VEGF). VEGF is suspected to play a role in the loss of vascular integrity in the eye, which is thought to be involved in the pathogenesis of macular edema in the eyes of patients with uveitis. Ranibizumab was approved by the FDA for the treatment of neovascular age-related macular degeneration on June 30, 2006, and a number of published papers have shown efficacy for other causes of macular edema, including that due to diabetes mellitus.
The F. I. Proctor Foundation at UCSF will be enrolling 10 subjects 18 years of age or older with uveitis-induced CME to clinically evaluate the safety and effectiveness of ranibizumab administered monthly for three months followed by PRN monthly dosing (up to 12 months). The study will measure visual acuity, changes in foveal thickness on optical coherence tomography, and changes in cystoid macular edema by fluorescein angiograpy to determine the efficacy of ranibizumab treatment.

Medical and Biotech [MESH] Definitions
Human histocompatibility (HLA) surface antigen encoded by the B locus on chromosome 6. It is strongly associated with acute anterior uveitis (UVEITIS, ANTERIOR); ANKYLOSING SPONDYLITIS; and REACTIVE ARTHRITIS.
Inflammation of the choroid as well as the retina and vitreous body. Some form of visual disturbance is usually present. The most important characteristics of posterior uveitis are vitreous opacities, choroiditis, and chorioretinitis.
Inflammation of the pars plana, ciliary body, and adjacent structures.
Abnormally low intraocular pressure often related to chronic inflammation (uveitis).
Inflammation of part or all of the uvea, the middle (vascular) tunic of the eye, and commonly involving the other tunics (sclera and cornea, and the retina). (Dorland, 27th ed)
Uveitic CME is a major cause of visual loss associated with uveitis. Systemic and/or local corticosteroid therapy and systemic immunosuppression with steroid-sparing agents such as cyclosp...
This is a pilot study to investigate the safety and efficacy of intravitreally administered ranibizumab (Lucentis) compared to steroid injection for the treatment of macular edema due to c...
The purpose of this study is to understand whether genes or certain factors in the environment determine how eyes will respond to Lucentis (ranibizumab) treatment. For example, whether ha...
