CATT Trial
After a one year delay the CATT Trial will begin recruiting patients in January 2008. It will have two primary purposes:

  • Compare the safety and efficiency of Lucentis and Avastin
  • Determine whether or not as-needed dosing can produce a visual result that is as robust as what has previously been demonstrated with fixed dosing

The study chairman is David F. Martin, M. D., at Emory University.

Gene RPE65 replacement therapy in Leber Congenital Amaurosis (LCA) is in clinical trials.

Investigational Therapies For Dry Age Related Macular Degeneration

Complement Inhibitors
Support for a paradigm that links aberrant complement activation with AMD was revealed in studies associating AMD with three genes, including factor H. Collectively, the three gene variations account for nearly 75% of all AMD cases in European and North American populations. The unanswered question is whether inhibiting complement so late in the disease process will alter disease progression or vision loss.

This agent halts accumulation of lipofuscin and toxic vitamin A metabolites. A two-year, phase 2 dose-ranging trial by Sirion is under way.

The National Eye Institute (NEI) is adding lutein and zeaxanthin to the Age Related Eye Disease Study (AREDS) formulation and is testing it in patients.

Ciliary Neurotrophic Factor (CNTF)
The company Neurotech is testing an implantable drug delivery system releasing the growth factor CNTF into the eye over time.

The company Potentia Pharmaceuticals is testing this complement inhibitor, which may block inflammation and angiogenic factors seen in age related macular degeneration (ARMD).

The company Othera and NEI are testing this agent, which may protect retinal pigment epithelium (RPE) cells and photoreceptors from oxidative damage and angiogenesis stimulated by vascular endothelial growth factor (VEGF).

Glatiramer Acetate
An ongoing study to test the drug Copaxone, which is used in treating multiple sclerosis, is being evaluated for its use in preventing progression of dry to the wet form of age related macular degeneration (ARMD).
