About ANB033

ANB033, a potentially best-in-class CD122 antagonist, targets CD122, the common beta subunit of IL-15 and IL-2, to reduce NK cells and subsets of cytotoxic CD8+ and CD4+ T cells that are dependent on IL-15 and/or IL-2 for their maintenance, and survival and pathogenic activity. Anaptys has initiated a Phase 1b cohort in an initial indication, celiac disease.
