About Allakos Allakos is a clinical stage biotechnology company developing antibodies that target immunomodulatory receptors present on immune effector cells involved in allergic, inflammatory, and proliferative diseases. The Company’s lead antibody, antolimab (AK002), targets Siglec-8, an inhibitory receptor selectively expressed on human mast cells and eosinophils. Antolimab (AK002) has been shown to inhibit mast cells and deplete eosinophils. Inappropriately activated eosinophils and mast cells have been identified as key drivers in a number of severe diseases affecting the gastrointestinal tract, eyes, skin, lungs and other organs. Antolimab (AK002) has been tested in five clinical studies. In these studies, antolimab (AK002) eliminated blood eosinophils and improved disease symptoms in patients with eosinophilic gastritis and/or eosinophilic gastroenteritis, eosinophilic esophagitis, severe allergic conjunctivitis, chronic urticaria, and indolent systemic mastocytosis.
