Tildrakizumab

Tildrakizumab (SCH 900222) is a humanized anti-IL-23 (p19 subunit) monoclonal antibody. IL-23 is a critical cytokine to maintain the Th17 cell phenotype. Tildrakizumab has high-affinity for single-chain IL-23 (Kd: 136 pM). Tildrakizumab is effective against moderate to severe plaque psoriasis[1][2][3].
