Developing treatment strategies to optimize outcomes in patients with psoriatic arthritis

Achieving sustained remission in psoriatic arthritis (PsA) remains challenging despite the availability of multiple biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Heterogeneous disease expression, comorbidities, and variable durability of response limit treatment effectiveness.

This review summarizes contemporary and emerging pharmacologic approaches to PsA, spanning established therapies targeting tumor necrosis factor (TNF), the interleukin-23/interleukin-17 (IL-23/IL-17) axis, and Janus kinase (JAK) signaling, as well as emerging strategies such as selective tyrosine kinase 2 (TYK2) inhibition, dual JAK1/TYK2 inhibition, oral interleukin-23 receptor-targeted peptides, and novel biologic platforms. A structured literature search of PubMed, MEDLINE, and ClinicalTrials.gov was conducted for studies published between January 2000 and April 2026. Evidence from randomized controlled trials, long-term extension studies, and real-world observational cohorts informed assessment of efficacy, durability, safety, treatment sequencing, and drug survival, with emphasis on multidomain involvement and metabolic and non-inflammatory drivers of disease activity.

Progress in PsA management will depend less on expanding therapeutic options and more on improving sustained remission rates. Phenotype- and mechanism-informed treatment selection, proactive treat-to-target implementation, and systematic reassessment of residual inflammatory versus non-inflammatory disease activity are central to optimizing long-term outcomes. Emerging therapies may refine existing strategies by improving durability and safety.
