Takeda announced positive topline results for the Phase 3, randomized, multicenter, double-blind study comparing zasocitinib (TAK-279), an investigational, next-generation, highly selective and potent oral tyrosine kinase 2 (TYK2) inhibitor, to deucravacitinib in adults with moderate-to-severe plaque psoriasis (PsO).

In the LATITUDE Atlas (TAK-279-PsO-3004) head-to-head study, zasocitinib demonstrated statistical superiority over deucravacitinib for the primary endpoint, Psoriasis Area and Severity Index (PASI) 100 response rate at week 16. The study also demonstrated statistical superiority over deucravacitinib for all key secondary endpoints, including PASI 90 response and Static Physician's Global Assessment (sPGA) 0 at week 16. Zasocitinib was generally well tolerated with a consistent safety and tolerability profile and no new safety signals identified.

These head-to-head results build on the strong efficacy seen across our Phase 3 program, with more than 35% of zasocitinib-treated patients achieving complete skin clearance (PASI 100) at week 16 – more than 2.5 times the response rate for deucravacitinib – and separation from the deucravacitinib curve as early as week 8, together, these findings reinforce the promise of zasocitinib to deliver rapid and durable skin clearance in a convenient once-daily pill and demonstrate the transformative potential of highly selective and potent TYK2 inhibition for patients suffering with plaque psoriasis.
