Spondyloarthritis & psoriatic arthritis

Phase 2 Trial of Deucravacitinib in Psoriatic Arthritis: Biomarkers Associated With Disease Activity, Pharmacodynamics, and Clinical Responses

Arthritis RheumatolPublished Secondary analysis of a phase 2 randomised trial

Authors' conclusion

Deucravacitinib significantly impacted biomarkers associated with Tyk2 signaling pathways of key inflammatory cytokines, including IL-23 and type I interferon, and those related to collagen matrix turnover.
