New and Noteworthy in Psoriasis

April W. Armstrong, MD, MPH, reviewed major recent developments shaping modern psoriasis management, beginning with the first consensus definition of on-treatment remission established through a Delphi process led by the National Psoriasis Foundation. This consensus defines remission as maintaining BSA 0% or IGA 0 for at least six months, providing a standardized, clinically meaningful target for long-term disease control and a consistent benchmark for evaluating durability across therapies and clinical trials.

Dr Armstrong also highlighted emerging oral therapies that are redefining expectations for systemic treatment. Icotrokinra, a novel targeted oral peptide that selectively inhibits IL-23 signaling, demonstrated superior efficacy compared with deucravacitinib in the ICONIC-ADVANCE trials, achieving higher rates of IGA 0/1 and PASI 90 at Weeks 16 and 24. Additional ICONIC data showed robust PASI 90 responses in adults and durable maintenance of PASI 75 and PASI 90 through 52 weeks in adolescents, supporting both potency and durability across age groups. Long-term extension data for the TYK2 inhibitor deucravacitinib demonstrated stable efficacy and a favorable safety profile through five years, including benefit in patients with psoriatic arthritis. Dr Armstrong also reviewed emerging data for highly selective TYK2 inhibitors such as envudeucitinib, which achieved stringent treat-to-target thresholds in a majority of patients at one year. Together, these advances reflect a shift toward precise, durable, and patient-friendly oral therapies that align with newly established remission goals in psoriasis.
