A Phase 2 Multicenter Open-Label Extension Study to Evaluate the Safety and Tolerability of AK002 in Patients with Eosinophilic Gastritis and/or Eosinophilic Gastroenteritis

Brief description of study

AK002 is a humanized non-fucosylated immunoglobulin G1 (IgG1) monoclonal antibody to the inhibitory receptor Siglec-8, present on mast cells, eosinophils, and basophils. Binding of AK002 to Siglec-8 induces a signal that inhibits mast cell activation and can lead to apoptosis in eosinophils. In the presence of effector cells (such as natural killer [NK] cells), AK002 binding to Siglec-8 depletes circulating eosinophils by ADCC and may reduce eosinophil and mast cell numbers in tissue. This profile of activity may provide clinical benefit in diseases in which these cell types play a role, such as EG and/or EGE.
