Bristol Myers Sotyktu Shows Two-Year PsA Efficacy in POETYK Study
Bristol Myers Squibb announced positive two-year results from the late-stage POETYK PsA-2 study of Sotyktu, or deucravacitinib, including its open-label extension. Among patients entering the extension, clinical responses improved from week 16 through week 52 and were sustained through week 104, with robust results across ACR20/50/70 and Minimal Disease Activity in both continuous Sotyktu patients and those who switched from placebo at week 16. The safety profile remained consistent through week 104 with no new safety signals; adverse events occurred in 86.6% of 604 patients exposed to Sotyktu, while serious adverse events and discontinuations due to adverse events were reported in 12.6% and 7.6% of patients, respectively. Sotyktu, an oral selective tyrosine kinase 2 inhibitor approved in the United States and numerous other countries for moderate-to-severe plaque psoriasis and active psoriatic arthritis, generated $156 million in first-half 2026 revenues, up 24% year over year. Data from the POETYK SLE-1 and SLE-2 studies in systemic lupus erythematosus are expected later in 2026, while Amgen's Otezla and Takeda's investigational zasocitinib, whose new drug application the FDA recently accepted for plaque psoriasis, remain competitive threats.
