Bioactivity Comments
Mirikizumab (Antibody I) binds monkey IL-23 with a Kd of 0.056nM, and rabbit IL-23 with a Kd of 53nM, but does not bind rat or mouse IL-23 or human IL-12, IL-27 or IL-35 [2]. Antibody I blocks binding of IL-23 to the IL-23R in vitro, but does not inhibit IL-23 binding to IL-12Rβ1 (the other subunit of the functional IL-23R heterodimer). Effects of Antibody I in vivo are described in the associated patent documentation [2].
