Lifitegrast (under brand name Xiidra) was approved as an ophthalmic solution for the treatment of the signs and symptoms of dry eye disease. Lifitegrast binds to the integrin lymphocyte function-associated antigen-1 (LFA-1); a cell surface protein found on leukocytes and blocks the interaction of LFA-1 with its cognate ligand intercellular adhesion molecule-1 (ICAM-1). This LFA-1/ICAM-1 interaction is a key step in the inflammatory cascade that contributes to dry eye disease. Besides lifitegrast participates in phase II clinical trials for prevention of the signs and symptoms of allergic conjunctivitis.
