Abstract

Dry eye disease is an extremely common condition affecting millions worldwide. The underlying pathophysiological mechanism is thought to be localized inflammation of the ocular surface resulting in the localization of T cells at this surface followed by their activation and subsequent liberation of cytokines. This effect on T cells results from the binding of lymphocyte function-associated antigen-1 (LFA-1) located on T cells to intercellular adhesion molecule 1 (ICAM-1) expressed on inflamed epithelium and endothelium, and on T cells. Lifitegrast is a T-cell integrin antagonist designed to mimic ICAM-1, thus blocking the interaction of LFA-1 and ICAM-1. Lifitegrast enters the systemic circulation to a limited extent thus reducing the likelihood of unwanted systemic reactions. Clinical trials in over 2,500 subjects with dry eye disease have shown that 5.0% lifitegrast given by ocular instillation causes a significant reduction in objective and subjective signs and symptoms of the disease. These beneficial effects are associated with a relatively low incidence of unwanted effects, almost all local in nature. In light of these findings, lifitegrast was approved by the Food and Drug Administration (FDA) in 2016 for the treatment of dry eye disease, the first drug with this mechanism of action to be so approved.
