Can the Next-Generation TYK2 Inhibitor, Zasocitinib, Raise the Bar in Plaque Psoriasis?
After strong Ph. 3 results and a completed head-to-head trial against ’s deucravacitinib (Sotyktu®), Takeda/Nimbus’ zasocitinib is emerging as a potential best-in-class oral TYK2 inhibitor.
Zasocitinib (TAK-279, NDI-034858) is an allosteric TYK2-JH2 inhibitor designed to selectively target the catalytically inactive pseudokinase domain of TYK2, avoiding the more conserved JH1 ATP-binding site shared across the JAK family.
In Takeda’s Ph. 3 Latitude PsO trials, ~70% of zasocitinib-treated patients achieved clear or almost clear skin at week 16, compared with ~10% on placebo and ~30% on the PDE4 inhibitor apremilast (Otezla®). Zasocitinib also produced substantially higher PASI90 and PASI100 responses, strengthening its case as an oral therapy with the potential to move closer to biologic-like efficacy.
Will zasocitinib pharmacologic differentiation translate into a clinically meaningful advantage over deucravacitinib?
