ANB020, now called etokimab, is currently in phase 2a testing in eczema, which is also known as atopic dermatitis. Scientists from the Medical Research Council Human Immunology Unit at the University of Oxford released data from 12 patients showing that 83% who were treated with etokimab reported a reduction in disease severity after 29 days. Etokimab, an anti-IL-33 biologic, has previously demonstrated a good safety profile and favorable pharmacodynamic properties in many clinical studies. Etokimab is designed to block interleukin-33 (IL-33), an immune-signaling molecule. In peanut allergy, the body overreacts to peanuts as IL-33 activates an antibody called immunoglobin E. These antibodies cause allergic response such as mouth itchiness, hives, breathing difficulties and potentially fatal anaphylactic shock.
