Description/comment

Molecular format included in "Pharmacological agents in development for diabetic macular edema" but this article was retracted for legal reasons. mAb for diabetic macular edema; longer half life. EBI-031 is a novel inhibitor of the cytokine IL-6 and is an optimized version of the company's anti-IL-6 antibody, EBI-029. The company believes that 031 has the identical binding site on IL-6 and same mechanism of action as 029. The company designed 031 to block IL-6 signaling at much lower concentrations that 029, potentially increasing the potency and potentially extending the time between required administrations. Humanized monoclonal antibody that potently binds interleukin-6 (IL-6) and inhibits all known forms of IL-6 cytokine signaling, for treatment of ocular diseases.
