Approvals in Europe and Japan are expected to follow on the heels of the U.S. Food and Drug Administration (FDA) approval for deucravacitinib in September 2022. As a novel oral, targeted agent that selectively inhibits tyrosine kinase 2 (TYK2), a Janus kinase (JAK) family member that mediates cytokine-driven immune and inflammatory signals, it has the potential to fill a gap in the treatment armamentarium for plaque psoriasis. In addition to its impact for these patients, it is being evaluated for other indications that could benefit more patient populations and boost overall sales.
Deucravacitinib is a first-in-class oral TYK2 inhibitor with a unique mechanism of action that inhibits signaling of IL-23, IL-12 and type 1 interferon (IFN), key cytokines involved in the pathogenesis of the multiple immune-mediated diseases for which deucravacitinib is being evaluated.
U.S. FDA approval was supported by results from two phase 3 trials, POETYK PSO-1 (deucravacitinib vs placebo) and POETYK PSO-2 (deucravacitinib vs twice-daily apremilast/Otezla®), with adults with moderate-to-severe plaque psoriasis in the United States, Europe and Japan, which showed:
