Burden and determinants of multi-b/tsDMARD failure in psoriatic arthritis

Arthritis Research & Therapy 2025;27:46 doi: 10.1186/s13075-025-03518-7

Haberman et al. analysed prescribing patterns and characteristics of PsA patients with
multi-b/tsDMARD failure, defined as requiring ≥4 b/tsDMARDs. Among 960 patients at the NYU Psoriatic Arthritis Centre, 17% met this criterion. These patients were more likely to be female, obese, and have higher rates of axial involvement and depression. They also exhibited greater disease activity, suggesting that both inflammatory and non-inflammatory factors contribute to multiple treatment failures.

October 2024

Kavanaugh et al. conducted a post hoc analysis of a phase 2 trial examining deucravacitinib in patients with active psoriatic arthritis, focusing on the achievement of MDA components.

The analysis demonstrated that treatment with deucravacitinib led to a higher proportion of patients meeting each MDA component compared with placebo at 16 weeks.

May 2024

FitzGerald, et al. found that Deucravacitinib significantly impacted biomarkers associated with TYK2 signalling pathways of key inflammatory cytokines, including IL-23 and Type I IFN, and those related to collagen matrix turnover.

January 2024

Week 16 coprimary endpoints of PASI 75 response and sPGA score improved in the majority of patients and was overall maintained through week 52. Deucravacitinib therapy was also associated with a low AE rate. This study presented results from the POETYK PSO-4 trial on the safety and efficacy of deucravacitinib 6mg QD in Japanese patients with psoriasis.

Researchers reported the safety and efficacy of deucravacitinib over 2 years in patients with chronic plaque PsO. The most frequently reported AEs were nasopharyngitis, URTI, and COVID-19.

August 2023

Phase IIb study of brepocitinib in patients with PsA concludes that treatment with brepocitinib 30 mg and 60 mg QD, was superior to placebo at reducing signs and symptoms of PsA and was well-tolerated over 52 weeks.

September 2022

This Phase 3 study by Strober, et al. reports deucravacitinib superiority to placebo and apremilast in patients with PsO. The authors found that deucravacitinib had significantly higher rates of PASI 75 and sPGA achievement than placebo and deucravacitinib.

July 2022

Deucravacitinib has shown efficacy in the treatment of both skin and joint disease. As a result, researchers sought to compare the efficacy and safety of deucravacitinib versus placebo and apremilast in adults with moderate to severe plaque PsO.

June 2022

In this study Mease, et al. aimed to evaluate the efficacy and safety of deucravacitinib in patients with active PsA. Treatment with the selective TYK2i deucravacitinib was well tolerated and resulted in greater improvements than placebo in ACR-20 as well as Multiplicity-controlled secondary endpoints and other exploratory efficacy measures in patients.
